Autores: Giura, L.; Urtasun Izquierdo, Leyre; Ansorena Artieda, Diana María (Autor de correspondencia); et al.Revista: FOOD RESEARCH INTERNATIONALISSN: 0963-9969 Vol.170 2023 págs. 112975ResumenEnriched lentil protein vegetable purees (10% zucchini, 10% carrots, 2.5% extra virgin olive oil and 21.8% lentil protein concentrate) suitable for people with dysphagia were developed with 0.8% xanthan gum (XG) or 600 MPa/5 min high pressure processing (HPP) treatment with the aim of comparing their rheological and textural properties. Selection of the appropriate XG % and HPP conditions was made by performing initial pilot trials. Purees showed a good nutritional profile (12% protein, 3.4% fiber, 100 Kcal/100 g), being adequate for people with dysphagia. Microbiological testing of HPP treated purees indicated that it has a good shelf-life under refrigerated conditions 14 days). Both types of purees showed a gel-like character (tan delta 0.161-0.222) and higher firmness, consistency and cohesiveness than control samples. Comparing XG and HPP samples at time 0, HPP treated purees showed the highest stiffness ( G '), the lowest deformability capacity (yield strainLVR) and the lowest structural stability (yield stressLVR). With storage, HPP treatment samples showed significant increases in all rheological and textural parameters. These results confirm the suitability of HPP as an alternative technology to hydrocolloids for the obtained dysphagia dishes.

Different treatments (250 MPa/15 min; 600 MPa/5 min) and protein concentrations (10-15%) were combined and evaluated for choosing the optimum combination leading to an adequate texture. The selected formulation was a dessert containing 4% cocoa and 10% casein and subjected to 600 MPa for 5 min. It showed a high nutritional value (11.5% protein) and high antioxidant capacity, which was slightly affected by the HPP processing. The rheological and textural properties showed that HPP had a clear effect on the dessert structure. The loss tangent decreased from 2.692 to 0.165, indicating the transition from a liquid to a gel-like structure, which is in a suitable range for dysphagia foods. During storage (14 and 28 days at 4 degrees C), progressive significant changes in the structure of the dessert were observed. A decrease in all rheological and textural parameters occurred, except for the loss of tangent, which increased its value. In any case, at 28 days of storage, samples maintained the weak gel-like structure (0.686 loss tangent) that is acceptable for dysphagia management.

In vitro digestion was not affected by the GA, with >90% lipolysis in all formulations, but was the most relevant variable, promoting oxidation (MDA) regardless of the oil type, GA or temperature applied. Tocopherols and phenolic decreased with digestion, which could be interpreted as a protective response to pro-oxidative conditions during digestion. Temperature decreased olive oil phenolics. Gelification of echium oil using alginate reduced secondary oxidation products formation in comparison with carrageenan, with oxidation degrees after digestion equivalent to those shown with olive oil. The use of alginate with olive oil resulted in the most stable formulations, although not protecting its minor bioactive compounds from thermal degradation.

This paper reviewed the effect of different vehiculization systems (hydrogels, emulgels and oleogels) as fat replacers in different types of bakery goods, focusing on technological and nutritional properties of the reformulated products. The most commonly used fat source for replacement purposes were vegetable oils with high monounsaturated fatty acid content, such as olive oil and canola oil (44% of the revised papers used them), whereas high polyunsaturated fatty acid content oils were used in 34% of papers. Oleogelation was the most frequent used method of oil structuring, using waxes and fibers as stabilizers. Reductions of total fat between 19% and 46% and saturated fatty acid between 33% and 87% were achieved, enough to reach the minimum legal limit to state nutrition claims, under the EU legislation, on several products. Sensory evaluation results showed that partially replaced products (<75% replacement) were more appreciated by panelists than fully replaced ones. This review highlights the wide range of alternatives within gel-like fat replacers, that have potential to be applied in different bakery products and the challenge to produce nutritionally enhanced foods and technologically and sensory acceptable.

P.; et al.Revista: FOOD & FUNCTIONISSN: 2042-6496 Vol.13 N° 9 2022 págs. 4861 - 4874ResumenRed-fleshed apple cultivars with an enhanced content of anthocyanins have recently attracted the interest of apple producers and consumers due to their attractive color and promising added health benefits. In this paper, we provide the first comprehensive overview of new hybrid red-fleshed apples, mainly focusing on their (poly)phenolic composition, the effect of processing, the (poly)phenolic bioavailability and the biological effects. Evidence so far from in vitro and in vivo studies supports their added beneficial effects compared to common apples on health outcomes such as cancer, cardiovascular disease, inflammation and immune function, which are mainly related to their specific (poly)phenol composition.

This study investigated the absorption, metabolism and excretion of (poly)phenols after sous-vide artichoke consumption (5776 µmol of (poly)phenols) by healthy volunteers. Seventy-six (poly)phenol metabolites were identified by UHPLC-MS/MS using authentic standards, including acyl-quinic acids plus C6¿C3, C6¿C1, C6¿C2, C6¿C1¿N, C6¿C0 metabolites, and their phase-II conjugates. The major metabolites were 3¿-methoxy-4¿-hydroxycinnamic acid, 3¿-methoxycinnamic acid-4¿-sulfate, and 4¿-hydroxycinnamic acid-3¿-sulfate, which appeared early in plasma (Tmax < 4 h); plus 3-(3¿-methoxy-4¿-hydroxyphenyl)propanoic acid, 3-(4¿-methoxyphenyl)propanoic acid-3¿-glucuronide, 3-(3¿-hydroxyphenyl) propanoic acid and hippuric acids, which appeared later (Tmax > 6 h). The 24 h urinary recovery averaged 8.9% (molar basis) of the (poly)phenols consumed. Hepatic beta-oxidation of 3¿,4¿-dihydroxycinnamic acid and methylated conjugates occurred, but was limited (<0.04%). 3¿-Methylation exceeded 4¿-methylation and interindividual variability was high, especially for gut microbial metabolites (up to 168-fold).

The content and composition of phenols and antioxidant activity was determined before and after in vitro digestion. The phenol content of the A20 and A21 samples were higher (> 75%) than that of the SP sample before in vitro digestion. After the entire in vitro digestion, 89.3, 76.9, and 50% loss of phenols was found in A20, A21 and SP, respectively. ABTS(center dot+) and ORAC values decreased during in vitro digestion of A20 and A21 samples, while they remained almost constant in SP. IC50 increased during digestion of A20 and A21, evidencing a loss of antioxidant capacity after the intestinal phase; an opposite IC50 trend was noted in SP, confirming the protective role of maltodextrins. For these reasons, SP represents a promising formulation to be used in the food field.

The control product was elaborated with butter and milk. Sugar was used in both types of formulations, but it was partially replaced by maltitol in the reformulated product. Decreases of 25% in energy and 67% in fat supply were achieved, as well as a 36% reduction in the sugar content. The saturated fatty acid amount was 0.57 g/100 g product, in contrast with the 9.45 g/100 g product found in control products. Differences in color were observed both through instrumental and sensory analysis, especially in the crust, with lower values for the Browning index in the reformulated products. The hedonic test, carried out with 44 untrained panelists, showed a good score for general acceptability (6.1 in contrast to 7.2 for control products), and no significant differences from the control were found for flavor.

Two proteins (casein and pea protein) and four hydrocolloids (guar gum, tara gum, xanthan gum and carboxymehtylcellulose) were combined and their behavior analyzed. The formulations were a good source of protein and antioxidants ensuring a significant supply of protein (6.1-6.7%) and antioxidant capacity (43-53mg phenolic compounds/100g). The addition of an optimum amount of hydrocolloids allowed the target "pudding" viscosity to be achieved. The formulations containing pea protein were more affected by freezing, which decrease their viscosity, and showed a weaker internal structure and a lower firmness after freezing/thawing when compared with casein formulations. Samples with xanthan gum in general showed better stabilit y. These results indicate that freezing can be a good alternative for preserving casein-enriched vegetable puree elaborated with xanthan gum designed for people with swallowing difficulties.

The aim of this work was to optimize the formulation of a gelled oil-in-water emulsion using echium oil (EO) or extra virgin olive oil (EVOO) and different hydrocolloids (alginate, cellulose with collagen and k-carrageenan) as a butter substitute, and assess their technological properties and oxidative stability. Out of 36 initial formulations, 6 were ultimately selected using a two steps process: firstly, on basis on hardness value (considering hardness of butter at room temperature as reference), and secondly searching for minimum syneresis. Oxidative stability of selected formulations was assessed after Schaal oven test. Oxidation parameters were influenced by the unsaturation degree of the oils (with statistically lower values for TBARs for gelled emulsions elaborated with EVOO as compared to those elaborated with EO), as well as by the required heating for the preparation of each gel type (with carrageenan showing statistically higher values in EO gels). Volatile profile of samples was characterized by the presence of aldehydes (35-45% of total area identified), followed by alcohols (11-21%) and esters (21-27%), with a statistically significant increase in aldehydes after 24 h in EO gels.

This work aimed to explore and characterize the fatty acid profile and sterol content of three non-conventional oils used in functional food products (hempseed oil, moringa oil, and echium oil) and to compare them with two conventional ones (extra virgin olive oil [EVOO] and linseed oil). Oxidative stability was assessed by determining their acidity value and peroxide content. All oils showed adequate values for acidity and oxidation status. Echium and hempseed oils showed a high content of polyunsaturated fatty acids (>70%), especially omega-3 fatty acids, while moringa oil was rich in oleic acid. Echium oil, hempseed oil, and moringa oil presented higher sterol content than EVOO, but lower than that of linseed oil. Sitosterol was the most abundant sterol in all samples (97.88¿275.36 mg/100 g oil), except in echium oil, where campesterol (170.62 mg/100 g oil) was the major sterol. Squalene was only found in significant amounts in EVOO. In conclusion, non-conventional oils seem to be interesting sources of bioactive compounds and have great potential for the food industry. Practical Application: Non-conventional vegetable oils can be used as alternative sources of lipids in a variety of food products. Additionally, these oils have great potential to be included in the formulation of functional ingredients for the delivery of omega-3 fatty acids, antioxidants, fiber, among others.

(Autor de correspondencia); Righi, N.; Daoud, I.; et al.Revista: SOUTH AFRICAN JOURNAL OF BOTANYISSN: 0254-6299 Vol.148 2022 págs. 315 - 325ResumenRanunculus macrophyllus Desf. is a multipurpose edible medicinal plant, whose roots are used to treat feminine infertility and to increase weight. The aim of this work was to study for the first time the acute toxicity and anti-inflammatory activity of their n-hexane extract. Gas chromatography was used to study the chemical composition of the extract, while xylene induced ear edema was used to assess its anti-inflammatory activity. In silico methods were used to determine the possible anti-inflammatory mechanism of action and pharmacokinetic behavior of the major compounds. Gas chromatographic analysis led to identification of 19 fatty acids, including linoleic, ¿-linolenic and palmitic acids as major compounds. The n-hexane extract did not induce any visible signs of toxicity or mortality to mice at 2000 mg/kg body weight, and successfully inhibited the xylene induced ear inflammation (67% at 200 mg/kg). This activity may be attributed to linoleic and ¿-linolenic acids that were found to be potent inhibitors of cyclooxygenase 2 and phospholipase A2 in the in silico study. The n-hexane extract exhibited strong anti-inflammatory activity with no acute toxicity, which opens the doors for the use of R. macrophyllus roots and their n-hexane extract in food, nutraceutical and pharmaceutical industries.

Hemp seed oil is characterized by a high content of polyunsaturated fatty acids, which are highly prone to oxidation. Accelerated thermal oxidation (60 degrees C, 18 days) has been applied to nine types of cold-pressed hemp seed oils to monitor the evolution of the samples during oxidative deterioration. The results showed that the only determinations of primary (peroxide value) and secondary (TBARs) oxidation products did not allow a sufficient or correct evaluation of the oxidative changes of hemp seed oils during storage. In fact, samples at the end of the test were primarily characterized by a high presence of oxidation volatile compounds and a significant decrease of antioxidants. Several volatiles identified before the accelerated storage, such as the predominant alpha-pinene and beta-pinene, gradually decreased during the accelerated storage period. On the other hand, aldehydes (hexanal, (E)-2-hexenal, heptanal, (E,E)-2,4-hexadienal, (E)-2-heptenal, (E,E)-2,4-heptadienal, (E,Z)-2,4-heptadienal, 2-octenal, nonanal, nonenal, 2,4-nonadienal, (E,E)- 2,4-decadienal and 2,4-decadienal), ketones (1-octen-3-one, 3-octen-2-one, (E,E)-3,5-octadien-2- one and 3,5-octadien-2-one), acids (propionic acid, pentanoic acid, hexanoic acid and heptanoic acid) and 2-pentyl-furan increased during the accelerated storage, as principal markers of oxidation.

Autores: Macià, A.; Romero, M. P.; Yuste, S.; et al.Revista: FOOD CHEMISTRYISSN: 0308-8146 Vol.384 2022 págs. 132612ResumenThe present study aimed to evaluate the metabolism and bioavailability of anthocyanins (ACN) and other phenolics from red-fleshed apple (RFA) and to define the intake biomarkers compared to common white-fleshed apple (WFA). Acute and sustained (6-week) interventions were combined in a randomized, controlled and parallel study with 121 hypercholesterolemic subjects. Another arm consuming ACN-rich infusion from aronia fruit (ARO) provided matched content and profile of ACN. Plasma, urine and faeces samples were analyzed using UPLC-MS/MS. Results showed higher bioavailability of ACN after ARO compared to RFA, showing a clear apple matrix effect. The dihydrochalcone phloretin-2'-O-glucuronide was the most discriminant intake biomarker of both apples. The urinary peonidin-3-O-galactoside was a good biomarker after both ARO and RFA intakes, whereas peonidin-O-arabinoside was reported to be specific from ARO. The elucidation of the phenolic metabolism and the selection of intake biomarkers is a promising approach to relate phenolic compounds and human health.

Autores: de Torre, M. P.; Cavero Remón, Rita Yolanda; Calvo Martínez, María Isabel (Autor de correspondencia)Revista: MOLECULESISSN: 1420-3049 Vol.27 N° 20 2022 págs. 7100ResumenAlzheimer's disease is a neurodegenerative disease characterized by progressive memory loss and cognitive impairment due to a severe loss of cholinergic neurons in specific brain areas. It is the most common type of dementia in the aging population. Although many anti-acetylcholinesterase (AChE) drugs are already available on the market, their performance sometimes yields unexpected results. For this reason, research works are ongoing to find potential anti-AChE agents both from natural and synthetic sources. In this study, 90 extracts from 30 native and naturalized medicinal plants are tested by TLC and Ellman's colorimetric assay at 250, 125 and 62.5 mu g/mL in order to determine the inhibitory effect on AChE. In total, 21 out of 90 extracts show high anti-AChE activity (75-100% inhibition) in a dose-dependent manner. Among them, ethanolic extract from aerial parts of O. vulgare ssp. vulgare shows an IC50 value 7.7 times lower than galantamine. This research also establishes the chemical profile of oregano extract by TLC, HPLC-DAD and LC-MS, and twenty-three compounds are identified and quantified. Dihydroxycinnamic acids and flavonoids are the most abundant ones (56.90 and 25.94%, respectively). Finally, total phenolic compounds and antioxidant properties are quantified by colorimetric methods. The total phenolic content is 207.64 +/- 0.69 mu g/mg of extract. The antioxidant activity is measured against two radicals, DPPH and ABTS. In both assays, the oregano extract shows high activity. The Pearson correlation matrix shows the relationship between syringic acids, a type of dihydroxybenzoic acid, and anti-AChE (r(2) = -0.9864) and antioxidant activity (r(2) = 0.9409 and 0.9976). In conclusion, the results of this study demonstrate promising potential new uses of these medicinal herbs for the treatment of Alzheimer's. Origanum vulgare ssp. vulgare and syringic acids, which have anti-AChE activity and beneficial antioxidant capacity, can be highlighted as potential candidates for the development of drugs for the treatment of Alzheimer's disease and other diseases characterized by a cholinergic deficit.

Thirty one (poly)phenols were quantified in red and white cardoon by HPLC-MS/MS, phenolic acids being >95%, and 5-caffeoylquinic and 1,5-dicaffeoylquinic acids the major ones. Although both varieties showed a similar profile, raw red cardoon had 1.7-fold higher (poly)phenol content than raw white cardoon. Culinary treatments decreased (poly)phenol content, but sous-vide cooked cardoon had a greater content than the boiled one, suggesting a protective effect. After gastrointestinal digestion, (poly)phenol bioaccessibility of boiled and sous-vide cooked cardoon (52.6-90.5%) was higher than that of raw samples (0.2-0.7%), although sous-vide system no longer played a protective effect compared to boiling. In summary, red cardoon was a richer source of bioaccessible (poly)phenols than white cardoon, even sous-vide cooked or boiled.

D.; et al.Revista: JOURNAL OF FUNCTIONAL FOODSISSN: 1756-4646 Vol.88 2022 págs. 104891ResumenSweet orange (SO) (Citrus sinensis) is a rich source of polyphenols. However, the bioactivity depends directly on the bioaccessibility affected by biological factors during the digestion process. Therefore, this study was performed in lyophilized SO samples before and after an in vitro digestion to obtain total phenolic content (TPC) by Folin-Ciocalteu assay and characterize its phenolic profile by HPLC-ESI-MS/MS with methanolic extracts. Simulating the passive diffusion of biocompounds, samples were dialyzed after intestinal digestion to obtain bioaccessible phenolic compounds (BPC). Ethanolic extracts were used in 3T3-L1 cell culture. The in vitro digestion process decreased 25% the bioaccessibility of SO polyphenols in the intestinal phase. The most abundant subgroup of polyphenols before and after in vitro digestion were the flavanones, representing more than 86% of TPC. Finally, lipid accumulation in cells induced to undergo adipogenesis and treated with BPC decreased although without significant differences at different concentrations.

Autores: Delgado, J.; Ansorena Artieda, Diana María; Van Hecke, T.; et al.Revista: MEAT SCIENCEISSN: 0309-1740 Vol.171 2021 págs. 108278ResumenThe assessment of the actual contribution of red or processed meat to increasing the risk of suffering cardiovascular diseases (CVD) requires identification of specific harmful components and their underlying pathological mechanisms. In regards to CVD, meat lipids and their oxidation products have been recurrently studied due to their implications on lipid metabolism, hypercholesterolemia, obesity, and risk of suffering vascular events such as stroke. The impact of excess NaCl intake on increasing blood pressure is well-established and processed meat products have been recognized as a major contributor to dietary sodium in developed countries. Recent evidence has also suggested carnitine from red meat, as a precursor for trimethylamine-N-oxide, which has been shown to cause atherosclerosis, may increase the risk of suffering CVD in experimental animals. The present review aims to provide an updated overview, including evidence, controversies and unresolved questions on both the epidemiology and mechanisms relating red and processed meat consumption to CVD.

A. ; et al.Revista: INTERNATIONAL JOURNAL OF GASTRONOMY AND FOOD SCIENCEISSN: 1878-450X Vol.25 2021 págs. 100389ResumenArtichokes are an important source of (poly)phenolic compounds, mainly caffeoylquinic acids, which consumption has been associated with health benefits. However, heat treatments have shown to affect the amounts of these bioactive food compounds. In the present study the influence of culinary techniques (boiling, griddling, and frying) on the total (poly)phenolic content of artichokes (Cynara Scolymus cv. Blanca de Tudela) was evaluated by LC-MS/MS. Additionally, the antioxidant capacity of cooked artichokes was evaluated by spectrophotometric methods. A total of 31 (poly)phenols were identified and quantified, being caffeoylquinic acids the most abundant compounds in raw artichokes accounting for more than 95% of total (poly)phenolic compounds. With the different culinary techniques, these compounds suffered degradation but also redistribution, probably due to isomerization and hydrolysis reactions. Frying and griddling showed the lowest content of (poly)phenolic compounds and antioxidant capacity suggesting thermal degradation. Boiling also provoked losses, which were mainly due to leaching of phenolic compounds into the water. However, it was the heat treatment that best preserved (poly)phenolic compounds in artichokes.

However, accurate high-throughput quantitative methods for estimating exposure covering a broad spectrum of (poly)phenols are lacking. We have developed and validated a high-throughput method for the simultaneous quantification of 119 (poly)phenol metabolites in plasma and urine using ultra high-performance liquid chromatography coupled with triple quadrupole mass spectrometry, with a very fast sample treatment and a single run time of 16 min. This method is highly sensitive, precise, accurate, and shows good linearity for all compounds (R2 > 0.992). This novel method will allow a quantitative assessment of habitual (poly)phenol intake in large epidemiological studies as well as clinical studies investigating the health benefits of dietary (poly)phenols.

(Autor de correspondencia); Ansorena Artieda, Diana María; Calvo Martínez, María Isabel; et al.Revista: FOOD BIOSCIENCEISSN: 2212-4292 Vol.40 2021 págs. 100904ResumenRanunculus macrophyllus Desf. is a lesser-known yet regularly used vegetable in Mediterranean folk diets for its nutritional and medicinal properties. There is a lack of scientific data on its nutritional value and functionality. Therefore, the aim of this study was to investigate the nutritional and the phytochemical composition and the effect of in vitro digestion on the antioxidant activity and on individual polyphenols from an ethyl acetate extract. The proximate composition analysis showed good amounts of carbohydrates (72.4% dry weight, dw) and crude proteins (15% dw), while mineral analysis showed considerable amounts of calcium, magnesium, iron and zinc among other elements. The lipidic fraction showed potential anti-thrombotic and anti-atherogenic potential with beta-linolenic acid (40.8%) and linoleic acid (16.9%) as major compounds. The ethyl acetate fraction showed good amounts of total polyphenols (235 mg GAE/100 g dw), flavonoids (43.5 mg QE/100 g dw) and flavonols (108 mg RE/100 g dw). The fraction showed good radical scavenging ability against 2,2-dipheny l-1-picrylhydrazyl (432 mg Trolox E/100 g dw), 2,2'-azino-bis (3-ethylbenzothiazoline-6-sulfonic acid (1240 mM Trolox E/100 g dw) and peroxyl radicals (14200 mM Trolox E/100 g dw) even after in vitro digestion. Caffeic and coumaric acids showed good bioaccessibility between 97 and 102% while catechin and luteolin had lower bioaccessibility ranging from 34.2 to 38.7%. R. macrophyllus Desf. was found to be a good source of nutritional and non nutritional bioactive compounds with good bioaccessibility, which make its application in food and pharmaceutical industries potentially beneficial.

Methods (Poly)phenols of raw and griddled green pepper (Capsicum annuum L.) submitted to in vitro-simulated gastrointestinal digestion were characterized by LC-MS/MS. Cytotoxicity (MTT, trypan blue and cell proliferation assays), DNA damage and DNA protection (standard alkaline and formamidopyrimidine DNA glycosylase (Fpg)-modified comet assay) of different concentrations of (poly)phenolic extracts were assessed in colon HT-29 cells. Results A total of 32 (poly)phenolic compounds were identified and quantified in digested raw and griddled green pepper. Twenty of them were flavonoids and 12 were phenolic acids. Griddled pepper doubled the (poly)phenol concentration compared to raw; luteolin 7-O-(2-apiosyl)-glucoside and quercitrin constituted the major (poly)phenols in both extracts. Raw and griddled pepper (poly)phenolic extracts impaired cell proliferation and induced low levels of Fpg-sensitive sites, in a dose-dependent manner, even at a non-cytotoxic concentration. None of the concentrations tested induced DNA strand breaks or alkaline labile sites. Nor did they show significant genoprotection against the DNA damage induced by H2O2 or KBrO3. Conclusions Green pepper (poly)phenols did not show genoprotection against oxidatively generated damage in HT-29 cells at simulated physiological concentrations, regardless of the application, or not, of a culinary treatment (griddling). Furthermore, high concentrations of (poly)phenolic extracts induced a slight pro-oxidant effect, even at a non-cytotoxic concentration.

Blanching (98 degrees C, 30 s) increased the total native chlorogenic acids content (1.2-fold vs raw cardoon), with no significant changes in DPPH antioxidant capacity, but with a decrease in ABTS antioxidant capacity (0.6-fold). Specifically, total di-caffeoylquinic acids (CQAs) increase (1.6-fold) counterbalanced the losses of 5-CQA (0.8-fold). All frying conditions (t85 degrees C = 5, 12 or 10 min, ttotal = 15, 15 or 30 min, respectively) decreased the antioxidant capacity (0.5-0.7-fold in DPPH, 0.5-0.9-fold in ABTS) of cardoon, but increased total flavonoid amount (3.6-3.7-fold) that remained at low levels. The Short (15 min) and Intense-heat Frying (t85 degrees C = 5 min) favoured the release of chlorogenic acids, particularly 5-CQA, from the food matrix. However, a longer frying process (30 min) induced an almost complete degradation of di-CQAs. Thus, it is desirable to limit the frying duration. When blanching and frying were combined, a higher thermal degradation of (poly)phenols was observed, but the Short and Intense-heat Frying remained the most suitable. This study highlights the importance of selecting optimal culinary conditions for vegetables that favour a high content on bioactive compounds and, therefore, their potential healthy properties.

Mill.) cladodes as a functional food increases because of their (poly)phenolic compounds and health-promoting ability. Extraction conditions are the basis to obtain the highest amount of bioactive compounds with antioxidant properties. Therefore, several individual and combination of extraction solvents and conditions were carried out. Even a great amount of (poly)phenols was extracted using 80% ethanol; the combination of solvents with different polarities (methanol, acetone and water) favored the extraction of flavonoids and antioxidant capacity (DPPH and ABTS radicals). The extract with the highest flavonoid content was that obtained by successive extractions. Additionally, in order to quantify (poly)phenols by HPLC-DAD, aglycones were released from glycosides by acid hydrolysis (0.6, 1.2, 1.5, and 1.7 M HCl) through reflux at 90 °C at different times (2 h and 3 h). Flavonoid aglycones (isorhamnetin, quercetin, and kaempferol) and phenolic acids (ferulic and 4-hydroxybenzoic acids) were identified and quantified. Acid hydrolysis with 1.5 M HCl during 2 h was the best for the release of flavonoid aglycones, without phenolic acid degradation. Likewise, less acidity (0.6 M HCl) does not completely release the aglycones whereas a higher acidity (1.7 M) and a longer time of reflux (3 h) resulted in the degradation of flavonoid aglycones.

Blanca de Tudela) after an in vitro gastrointestinal digestion and the effect of the human colonic microbiota. A total of 28 (poly)phenolic compounds were identified and quantified by LC-MS/MS in raw, boiled, sous vide and microwaved Tudela artichokes. Out of these, sixteen were phenolic acids, specifically caffeoylquinic acids (CQAs) and other minor hydroxycinnamic acid derivatives, ten flavonoids belonging to the family of flavones (apigenin and luteolin derivatives) and two lignans (pinoresinol derivatives). Sous vide and microwaving caused mainly transesterification reactions of CQAs but maintained or even augmented the total (poly)phenolic contents of artichokes, while boiling decreased (poly)phenolic compounds by 25% due to leaching into the boiling water. Heat treatment exerted a positive effect on the bioaccessibility of (poly)phenols after gastrointestinal digestion. In raw artichokes, only 1.6% of the total (poly)phenolic compounds remained bioaccessible after gastrointestinal digestion, while in artichoke samples cooked by sous vide, boiled and microwaved, the percentage of bioaccessibility was 60.38%, 59.93% and 39,03% respectively. After fecal fermentation, 20 native (poly)phenolic compounds and 11 newly formed catabolites were quantified. 48 h of fecal fermentation showed that native (poly)phenols are readily degraded by colonic microbiota during the first 2 h of incubation. The colonic degradation of artichoke (poly)phenols follows a major pathway that involves the formation of caffeic acid, dihydrocaffeic acid, 3-(3 '-hydroxyphenyl)propionic acid, 3-phenylpropionic acid and phenylacetic acid, with 3-phenylpropionic acid being the most abundant end product. The catabolic pathways for colonic microbial degradation of artichoke CQAs are proposed.

Wistar rats are fed with high-fat diet (HFD) to induce hypercholesterolemia and supplemented with red-fleshed apple (HFD+R), white-fleshed apple (HFD+W), or an ACN-rich infusion from aronia fruit (HFD+A) providing matched content and profile of ACN. Plasma biochemical parameters, histological analysis, and phenol biological metabolites are determined. Plasma, urine, and feces show a significant increase of ACN metabolites after HFD+R and HFD+A, while flavan-3-ols are significantly increased after HFD+W and dihydrochalcones derivatives increased after both apples supplementation. A cardioprotective effect is observed after both apples and aronia infusion supplementation in the reduction of aortic thickness. The kidney function is improved after all supplementations and a decrease in insulin plasma concentration after both apples supplementation (HFD+R and HFD+W) is also observed. The findings support that ACN without apple matrix can induce cardioprotective effects. ACN or flavan-3-ols, together with dihydrochalcones, compose a phenolic phytocomplex in red- and white-fleshed apples, respectively, which can act synergistically in the attenuation of cardiovascular outcomes in hypercholesterolemic rats.

Raw cardoon after in vitro GI digestion had 0.7% bioaccessible (poly)phenols, which protected against lipopolysaccharide-induced inflammation by counteracting IL-8, IL-6, TNF-alpha, and IL-10 secretions in differentiated Caco-2 cells. Contrarily, GI-digested sous vide cardoon showed higher (poly)phenol bioaccessibility (59.8%) and exerted proinflammatory effects in Caco-2 cells. (Poly)phenols were highly metabolized during the first 8 h of in vitro fermentation, and nine catabolites were produced during 48 h of fermentation. Colonic-fermented raw and sous-vide-cooked cardoon did not show anti-inflammatory activity in HT-29 cells but presented potential prebiotic activity, comparable to the commercial prebiotic FOS, by stimulating health-promoting bacteria such as Bifidobacterium spp. and Lactobacillus/Enterococcus spp. and by increasing the production of total SCFAs, especially acetate.

However, while the impact of whole-apple intake on cardiovascular disease (CVD) remains unknown. This narrative review summarizes a novel integrated view of whole-apple intake, CVD risk association (through observational studies; OSs), and the effects on CVD risk factors (randomized trials; RTs). In 8 OSs, whole-apple intake was associated with a reduced risk of CVD mortality, ischemic heart disease mortality, stroke mortality, all-cause mortality, and severe abdominal aortic calcification, as well as with lower C-reactive protein (CRP) concentrations. In 8 RTs, whole-apple consumption reduced total cholesterol, low-density lipoprotein cholesterol, systolic blood pressure, pulse pressure, and plasma inflammatory cytokines, and noticeably reduced CRP, whereas it increased high-density lipoprotein cholesterol (HDLc) and improved endothelial function. Thus, consuming between 100 and 150 g/day of whole apples is associated with a lower CVD risk and decreases in blood pressure, pulse pressure, total cholesterol, low-density lipoprotein cholesterol, and inflammation status as well as with increases in HDLc and endothelial function. These results, support the regular consumption of whole apples as an aid in the prevention of CVD.

The concentration of large numbers of Native Americans at the Missions, along with the introduction of European diseases, led to serious disease problems. Medicinal supplies brought to California by the missionaries were limited in quantity. This situation resulted in an opportunity for the sharing of knowledge of medicinal plants between the Native Americans and the Mission priests. The purpose of this study is to examine the degree to which such sharing of knowledge took place and to understand factors that may have influenced the sharing of medicinal knowledge. The study also examines the sharing of medicinal knowledge between the Native Americans and the Californios following the demise of the California Missions. Methods Two methods were employed in the study: (1) a comparison of lists of medicinal plants used by various groups (e.g., Native American, Mission priests, Californios) prior to, during, and after the Mission period and (2) a close reading of diaries, reports, and books written by first-hand observers and modern authorities to find accounts of and identify factors influencing the exchange of medicinal information.

We carried out comprehensive gut microbiota analysis and targeted metabolomics in a cross-sectional study of 29 non-treated hypertensive (HT) and 32 normotensive (NT) subjects. We determined fecal microbiota composition by 16S rRNA gene sequencing and bacterial functions by metagenomic analysis. The microbial metabolites analysed were short chain fatty acids (SCFA) both in plasma and feces, and trimethylamine N-oxide (TMAO) in plasma. The overall bacterial composition and diversity of bacterial community in the two groups were not significantly different. However, Ruminococcaceae NK4A214, Ruminococcaceae_UCG-010, Christensenellaceae_R-7, Faecalibacterium prausnitzii and Roseburia hominis were found to be significantly enriched in NT group, whereas, Bacteroides coprocola, Bacteroides plebeius and genera of Lachnospiraceae were increased in HT patients. We found a positive correlation between the HT-associated species and systolic and diastolic blood pressure after adjusted for measured confounders. SCFA showed antagonistic results in plasma and feces, detecting in HT subjects significant higher levels in feces and lower levels in plasma, which could indicate a less efficient SCFA absorption. Overall, our results present a disease classifier based on microbiota and bacterial metabolites to discriminate HT individuals from NT controls in a first disease grade prior to drug treatment.

Nutritional, technological, and sensory characteristics of the reformulated products were assessed, as well as the stability under storage at room temperature. One control and six modified formulations with three levels of butter replacement (50%, 75%, and 100%) were analyzed. Modified muffins improved their nutritional profile, reducing up to 78% of fat and increasing fiber (up to 62.5%) and omega¿3 fatty acids content (from 0.12 g/100 g of product to 0.62 g and 1.55 g in hemp and flaxseed oil samples, respectively). Sensory analysis revealed that flaxseed oil samples were indistinguishable from the control in all evaluated attributes, even in the highest level of replacement. During storage, texture of modified samples behaved similar to the control and no oxidation problems were observed in any of the formulations. Therefore, the functional ingredient proved to be a feasible alternative for replacing butter in muffins, preserving the quality attributes and making them healthier foods.

Although the potential of dried blood spot (DBS) cards, the use of this technique for blood sampling and subsequent analysis of these fat-soluble micronutrients has been poorly or not studied. An analytical method based on DBS cards (FTA® DMPK-A) combined with liquid chromatography coupled to tandem mass spectrometry (LC-MS/MS) has been developed and validated for the determination of carotenoids (lutein, zeaxanthin, ß-cryptoxanthin and ß-carotene), tocopherols (¿-tocopherol, ¿-tocopherol and ¿-tocopherol) and all-trans-retinol in human blood. Under optimum DBS card extraction conditions, the extraction recoveries of the studied compounds were higher than 72%, the sample matrix effect lower than 17%, and the detection limits at hundred nM concentration levels. The developed method was applied to the analysis of human blood, and the concentration ranges obtained fell within the expected ranges previously reported in healthy adults. Moreover, the influence of hematocrit effect was investigated in a range of 25-55% in order to compare the obtained results to those reported in the literature for the analysis of plasma samples. This method represents an improvement over current techniques reported in the literature due to the use of a non-invasive blood collection method, and moreover, this methodology was for the first time 1) validated for the analysis of all-trans-retinol, tocopherols and carotenoids, and 2) applied for the determination of tocopherols in human blood samples.

Oxidative stress is an imbalance between free radicals and antioxidants, so today, compounds capable of reducing or neutralizing free radicals are being studied for a therapeutic use. Origanum vulgare L. is a traditional medicinal plant used for a wide number of health problems due to its antimicrobial, carminative and antioxidant activities. However, when administered orally, gastrointestinal digestion can modify some of therapeutical properties. To avoid this, two different solid oral formulations have been designed for an O. vulgare extract evaluating their antioxidant behaviours in vitro and in vivo after a simulation of gastrointestinal digestion. The results showed that the divided powder has a lower antioxidant activity both in vitro and in vivo than the encapsulated extract. The quantitative difference of polyphenols found on HPLC-DAD (especially luteolin, apigenin and caffeic acid) may explain the differences in pharmacological activity. Thus, we propose that the best form to administrate O. vulgare extracts to maintain the antioxidant properties is the encapsulated form, that is, two capsules of 250mg of a hydroalcoholic extract of O. vulgare with a minimum of 33 % of rosmarinic acid as a daily dose.

We further investigated the processing effect on the (poly)phenol bioavailability in a crossover postprandial study where three subjects consumed three apple products (freeze-dried snack, hot air-dried snack and pasteurized puree). (Poly)phenolic compounds present in the apple products and their biological metabolites in urine were analyzed using liquid chromatography coupled to mass spectrometry (UPLC-MS/MS). When comparing different processes, infrared-drying caused important losses in most of the apple (poly)phenolics, while hot air-drying and puree pasteurization maintained approximately 83% and 65% of total (poly)phenols compared with the freeze-dried snack, respectively. Anthocyanins in particular were degraded to a higher extent, and hot air-dried apple and pasteurized puree maintained respectively 26% and 9% compared with freeze-dried apple snack. The acute intake showed that pasteurized puree exhibited the highest (poly)phenol bioavailability, followed by hot air-drying and freeze-dried snack, highlighting the impact of processing on (poly)phenols absorption. In conclusion, for obtaining affordable new red-fleshed apple products with enhanced (poly)phenol bioavailability, puree pasteurization and hot air-drying represent viable techniques. However, to obtain a red-fleshed apple snack with high anthocyanin content, freeze-drying is the technique that best preserves them.

N.; Polyviou, T.; et al.Revista: FREE RADICAL BIOLOGY AND MEDICINEISSN: 0891-5849 Vol.160 2020 págs. 784 - 795ResumenThe health benefits of orange juice (OJ) consumption are attributed in part to the circulating flavanone phase II metabolites and their microbial-derived ring fission phenolic catabolites. The present study investigated these compounds in the bloodstream after acute intake of 500 mL of OJ. Plasma samples obtained at 0, 1, 2, 3, 4, 5, 6, 7, 8 and 24 h after OJ intake were analysed by HPLC-HR-MS. Eleven flavanone metabolites and 36 phenolic catabolites were identified and quantified in plasma. The main metabolites were hesperetin-3'-sulfate with a peak plasma concentration (C-max) of 80 nmol/L, followed by hesperetin-7-glucuronide (C-max 24 nmol/L), hesperetin-3'-glucuronide (C-max 18 nmol/L) and naringenin-7-glucuronide (C-max 21 nmol/L). Among the main phenolic catabolites to increase in plasma after OJ consumption were 3'-methoxycinnamic acid-4'-sulfate (C-max 19 nmol/L), 3-hydroxy-3-(3'-hydroxy-4'-methoxyphenyl)propanoic acid (C-max 20 nmol/L), 3-(3'-hydroxy-4'-methoxyphenyl)propanoic acid (C-max 19 nmol/L), 3-(4'- hydroxyphenyl)propanoic acid (C-max 25 nmol/L), and 3(phenyl)propanoic acid (C-max 19 nmol/L), as well as substantial amounts of phenylacetic and hippuric acids. The comprehensive plasma pharmacokinetic profiles that were obtained are of value to the design of future ex vivo cell studies, aimed at elucidating the mechanisms underlying the potential health benefits of OJ consumption.

Despite their presumed importance, these gut microbiota-derived compounds have, to date, in terms of biological activity, been considered subordinate to their parent dietary compounds, the flavan-3-ol monomers and proanthocyanidins. In this review, the role and prospects of PVLs and PVAs as key metabolites in the understanding of the health features of flavan-3-ols have been critically assessed. Among the topics covered, are proposals for a standardised nomenclature for PVLs and PVAs. The formation, bioavailability and pharmacokinetics of PVLs and PVAs from different types of flavan-3-ols are discussed, taking into account in vitro and animal studies, as well as inter-individual differences and the existence of putative flavan-3-ol metabotypes. Synthetic strategies used for the preparation of PVLs are considered and the methodologies for their identification and quantification assessed. Metabolomic approaches unravelling the role of PVLs and PVAs as biomarkers of intake are also described. Finally, the biological activity of these microbial catabolites in different experimental models is summarised. Knowledge gaps and future research are considered in this key area of dietary (poly) phenol research.

Chromatographic analysis indicated that catechins were the major polyphenols present in the Prunus spinosa L. extract. The antioxidant capacity increased as a result of the extract addition, as shown by the comparison of the gel emulsions, with and without it (APG and AG, respectively). Beef patties containing APG as fat replacer (modified patties) had a lower fat content (5.3% versus 10.75%), doubled the antioxidant activity and the DHA content, and improved the stability against oxidation by reducing the peroxide content more than two fold when compared to control patties. In addition, instrumental color measured by the CIE L*a*b* system showed no significant difference between control and modified raw patties. Moreover, the sensory acceptability of the new formulation was confirmed by a like/dislike hedonic test.

Its antioxidant capacity can be analyzed by different methods both in vitro and in vivo. Caenorhabditis elegans is an in vivo model widely used in ageing research. Until now, available tests analyze functional effects in the worms, so the antioxidant activity of the compound is indirectly monitored. We have developed a simple and a reliable method to quantify internal antioxidant activity in vivo. To validate this method, we analyzed an aqueous green tea extract and two other compounds with a well-known antioxidant activity and without this activity. The results obtained (EC50 green tea = 21.76 ± 1.28 µg/mL; EC50 positive control = 8.50 ± 0.33 µg/mL; negative control EC50 > 500 µg/mL) can help in the design of further in vivo experiments. Thus, our method can be used as a previous screening capable of reducing the gap between in vitro and in vivo assays.

The nutritional improvement achieved led to products able to include certain nutrition and health claims in the labelling. Sensory characterization by 62 consumers and the effect of nutritional information of the samples were also evaluated by using hedonic tests for liking, Check-All-That-Apply (CATA) questions and purchase intention. After having received the nutritional information about the new products, consumers reported a significant increase in the purchase intention and overall acceptability of the reformulated beef patties (P < 0.05) compared to these products under the blind conditions. In particular, 54 out of 62 consumers showed a higher acceptability for reformulated beef patties after receiving the nutritional information. This work highlighted the influence of nutritional information on sensory acceptability of reformulated healthier beef patties.

Objective: The presence of labeling messages related to nutrients, health properties, allergens, and additives in meat products marketed in Spain was analyzed in this work. The data collection was done through the web pages of six Spanish meat industries, and 642 products were gathered. The following labeling information was collected: the presence of nutrition claims, the presence of health claims, messages indicating the absence of additives, and those reporting the absence or presence of allergenic substances. Results: A total of 1,254 messages were found with the following distribution: 72% were related to the presence/absence of allergens, 19% were nutrition claims, 8% were messages related to the absence of additives, and only 0.4% were health claims. Fat was the nutrient most frequently referred in the nutrition claims, accounting for a 63.5% of this type of claims, with the expression 'low-fat', as the most used (42% of total nutrition claims). Prevalence of processed meat products that showed nutrition claims was 29%, whereas the percentage of products that showed information about allergenic compounds was 83%. Conclusion: This work provides information about the presence of health-related messages in a high number of meat products, which could be useful as a tool for marketing purposes or for consumer trends evaluation studies.

Autores: de Santiago Castanedo, Elsy Gabriela; Gill, C. I. R.; Carafa, I.; et al.Revista: JOURNAL OF AGRICULTURAL AND FOOD CHEMISTRYISSN: 0021-8561 Vol.67 N° 9 2019 págs. 2490 - 2499Resumenhe bioactivity of (poly)phenols from a food is an interplay between the cooking methods applied and the interaction of the food with the gastrointestinal tract. The (poly)phenolic profile and biological activity of raw and cooked cactus (Opuntia ficus-indica Mill.) cladodes following in vitro digestion and colonic fermentation were evaluated. Twenty-seven (poly)phenols were identified and quantified by HPLC-ESI-MS, with piscidic acid being the most abundant. Throughout the colonic fermentation, flavonoids showed more degradation than phenolic acids, and eucomic acid remained the most relevant after 24 h. The catabolite 3-(4-hydroxyphenyl)propionic acid was generated after 24 h of fermentation. Cytotoxicity, genotoxicity, and cell cycle analyses were performed in HT29 cells. Cactus colonic fermentates showed higher cell viability (>= 80%) in comparison to the control fermentation with no cactus and significantly (p < 0.05) reduced H2O2-induced DNA damage in HT29 cells. Results suggest that, although phenolic compounds were degraded during the colonic fermentation, the biological activity is retained in colon cells.

This study aimed assessing the quantity and quality of the lipid fraction in artisan and industrial biscuits. Seven artisan and five industrial brands of biscuits were analyzed. Total fat was statistically higher for the artisan biscuits (29.46%) than for the industrial ones (26.85%). Lipid profile revealed significant differences in TFA and SFA between both types of products, with lower values in industrial biscuits (0.75 g and 44.15 g/100 g of total fat, respectively) compared to artisan biscuits (1.81 g and 51.24 g/100 g of total fat). Artisan biscuits showed TFA values between 0.99 and 3.50 g/100 g fat, including 2 brands showing mean values higher than 2%. All industrial biscuits showed TFA values lower than 1% and a healthier lipid fraction as compared to artisan ones.

Replacement with regular canola oil increased hardness and lightness (P < .05) of the reformulated products as compared to those with beef fat. Structuring the oil resulted in similar color and texture (P > .05), and lower oxidation values (P < .05) of meat batters. Reformulated products also gave rise to a healthier fatty acid profile, evidenced by a decrease in saturated fatty acids (SFA) from 11.8% to approximate to 2% and an increase in polyunsaturated fatty acids (PUFA) from 0.3% to approximate to 5%. Omega-6 to omega-3 ratio also decreased (16.2 to approximate to 2) when incorporating canola oil into meat batters. Batters formulated with organogels showed improved matrix stability compared to those with hydrogelled emulsions, which showed some coalescence of fat globules and fat losses during cooking, resulting in a reduction of fat content (P < .05).
