RESUMEN
Most of daily eaten food are cooked, which helps in absorbing nutrients and phytochemicals, but at the same time it can decrease its content. Currently, the impact of cooking has been studied that could influence food health related compounds, but they have a limited view of compounds by not consider molecular structural modifications and new compounds formation. An untargeted approach using LC-ESI-LQT-Orbitrap-MS/MS and univariate/multivariate statistical analysis was applied to understand how the preparation of a recipe, varying its ingredients (olive oil, 5-10%; onion, 20-40%; and garlic, 2-4%) and cooking time, could modulate the chemical profile of a tomato sofrito sauce. The presence of unexplored compounds that may have a beneficial effect on health, such as phytoprostanes, hydroxycinnamic acid amides and compounds such as 3,4 dihydroxyphenylglycone was revealed. Moreover, cooking was able to modulate the content of compounds like aminoacids, thiosulfates or phenolics and could be used as a tool to increase these molecules. The untargeted approach on cooking allows to use a recipe as a tool to improve a chemical profile of a dish, which opens the view for new dietary recommendations by cuisine to improve our diet, habits and health.

BACKGROUND: Sofrito, a basic culinary technique widely used in the Mediterranean, may preserve dietary polyphenols and enhance their intake in the Mediterranean population. The aim of this study was to investigate if the sofrito technique improves the polyphenol extractability in a tomato-based sofrito sauce. RESULTS: A full factorial design was applied using mathematical models. The content of chlorogenic acid, ferulic acid hexoside and naringenin was higher in the sofrito sauce than in raw tomato. The bioaccessibility of some tomato polyphenols was enhanced by the presence of olive oil and they were protected from oxidation during the cooking process by the use of onion. CONCLUSION: The use of olive oil and onion in Mediterranean cooking as a base for sauces and dishes, with an appropriate cooking time, preserve the polyphenol content of food. Thus, Mediterranean cuisine may contribute to the health effects of the Mediterranean diet. © 2019 Society of Chemical Industry.

Extra-virgin olive oil (EVOO) is largely appreciated for its proven nutritional properties. Additionally, organic foods are perceived as healthier by consumers. In this context, the aim of the present study was to compare the phenolic profiles of EVOO from olives of the Hojiblanca variety, cultivated under organic and conventional systems. The quantification and identification of individual polyphenols was carried out by liquid chromatography coupled to mass spectrometry in tandem mode (LC-MS/MS). Significantly higher levels (p < 0.05) of phenolic compounds were found in organic EVOOs. The methodology used was able to detect previously unreported differences in bioactive components between organic and conventional EVOOs.

Sofrito is a Mediterranean tomato-based sauce that typically also contains olive oil, onion, and garlic. The preparation of sofrito modifies the bioactive compounds (carotenoids and polyphenols) in the ingredients to more bioavailable forms, promoting cis-lycopene formation and polyphenol bioaccessibility. To evaluate the health benefits of this cooking technique, the effect of consuming an acute dose of sofrito on the inflammatory status was studied. In a clinical trial, 22 healthy male subjects consumed a single dose of sofrito (240 g/70 kg) after three days without ingesting any tomato products and following a low-antioxidant diet the day before the intervention. Plasma carotenoids and total polyphenol excretion (TPE) were evaluated, as well as the inflammatory biomarkers C-reactive protein (CRP), interleukin-6 (IL-6), interleukin 1ß (IL-1ß) and tumor necrosis factor-α (TNF-α). After the sofrito intake, a significant decrease in CRP (p = 0.010) and TNF-α (p = 0.011) was observed, but only TNF-α was inversely correlated with an increase in TPE and plasma ß-carotene (not the major carotenoid, lycopene). The positive health effects of this tomato-based product may be attributed not only to lycopene, but to the bioactive compounds of all the ingredients.

Olive oil is the main source of fat in the Mediterranean diet and the most frequently used ingredient in Mediterranean cuisine. Cooking with olive oil has been attracting attention because it can act as a food excipient, thereby increasing the bioaccessibility and bioavailability of ingested bioactive compounds. The aim of this study was to understand the effect of cooking with olive oil on the bioactive components in other ingredients (tomato, onion, and garlic) of sofrito sauce, a representative model of Mediterranean cuisine. After the cooking process, polyphenols from tomato, onion, and garlic were detected in the olive oil, especially naringenin, ferulic acid, and quercetin, as well as a high content of carotenoid Z-isomers, which are more bioavailable than the E-isomers. Therefore, traditional Mediterranean cuisine could play an important role in the health-improving effects of the Mediterranean diet.

As common constituents of tomatoes and other fruits and/or vegetables, naringenin and quercetin are usually ingested together, so for a clearer understanding of their bioavailability, metabolic fates and health benefits, it is more insightful to study them together. The purpose of the present work was to study how co-administration of naringenin and quercetin at realistic doses (3.5 µg ml(-1) and 2.36 µg ml(-1), respectively) influences their absorption and intestinal first-pass metabolism. A single-pass intestinal perfusion model in mice (n = 4-6) was used. Perfusate (every 10 minutes), blood (at 60 min) and bile samples were analysed by an UPLC-ESI-MS/MS method to evaluate the presence of the aglycones and their metabolites. Both naringenin and quercetin showed high permeability coefficients when administered separately (7.71 ± 0.82 × 10(-4) cm s(-1)vs. 7.30 ± 1.95 × 10(-4) cm s(-1), respectively), but these values decreased by 50% with co-administration (4.09 ± 0.89 × 10(-4) cm s(-1) for naringenin and 3.18 ± 0.45 × 10(-4) cm s(-1) for quercetin). Moreover, the level of phase II metabolites in perfusion, plasma and bile samples increased when naringenin and quercetin were administered together. The higher biliary excretion of these metabolites could thus favour the entero-hepatic recycling of the aglycones and metabolites. The results of this study may have several useful applications: to know and consider the possible interactions between polyphenols and drugs that use the same mechanism of absorption and elimination; when polyphenol-rich nutritional supplements are supplied, and in our regular diets to optimize the health benefits afforded by the biological activities of such aglycones and/or metabolites.

SCOPE: This work aims to evaluate changes in the fecal metabolomic profile due to grape seed extract (GSE) intake by untargeted and targeted analysis using high resolution mass spectrometry in conjunction with multivariate statistics. METHODS AND RESULTS: An intervention study with six crossbred female pigs was performed. The pigs followed a standard diet for 3 days, then they were fed with a supplemented diet containing 1% (w/w) of MegaNatural® Gold grape seed extract for 6 days. Fresh pig fecal samples were collected daily. A combination of untargeted high resolution mass spectrometry, multivariate analysis (PLS-DA), data-dependent MS/MS scan, and accurate mass database matching was used to measure the effect of the treatment on fecal composition. The resultant PLS-DA models showed a good discrimination among classes with great robustness and predictability. A total of 14 metabolites related to the GSE consumption were identified including biliary acid, dicarboxylic fatty acid, cholesterol metabolites, purine metabolites, and eicosanoid metabolites among others. Moreover, targeted metabolomics using GC-MS showed that cholesterol and its metabolites fecal excretion was increased due to the proanthocyanidins from grape seed extract. CONCLUSION: The results show that oligomeric procyanidins from GSE modifies bile acid and steroid excretion, which could exert a hypocholesterolemic effect.

Proanthocyanidin (PAC) consumption has been linked to better colonic health, but PACs are poorly absorbed, making them a target for colonic metabolism. The resulting metabolites are low molecular weight and could potentially be absorbed. To understand the effects of dietary PACs it would be important to resolve the metabolic issue and link these changes to microbial population changes in a suitable model for human digestion. Here, six crossbred female pigs were fed a diet containing 1% (w/w) of MegaNatural® Gold grape seed extract (GSE) daily for 6 days. Fecal samples were analyzed by normal phase LC coupled to fluorescence detection and LC-MS/ToF. DNA was extracted from pig fecal samples and the V3/V4 region of the 16S rRNA gene was sequenced using an Illumina MiSeq. Intact parent PACs (dimer-pentamer) were observed in the feces on days 3 and 6 at similar high levels (â¼400 mg kg(-1) total) during ingestion of GSE but were absent 48 h post-feeding. The major phenolic metabolites were 4-hydroxyphenylvaleric acid and 3-hydroxybenzoic acid which increased by â¼30 and 3 mg kg(-1) respectively. The GSE diet also caused an ecological shift in the microbiome, dramatically increasing Lachnospiraceae, Clostridales, Lactobacillus and Ruminococcacceae. The relationship between dietary PACs and colon health may be attributable to the altered bacterial populations or phenolic compounds in the colon.

This paper describes for the first time a complete characterisation of the phenolic compounds in different anatomical parts of the Albariño grape. The application of high-performance liquid chromatography coupled with two complementary techniques, hybrid quadrupole time-of-flight and triple-quadrupole mass spectrometry, allowed the phenolic composition of the Albariño grape to be unambiguously identified and quantified. A more complete phenolic profile was obtained by product ion and precursor ion scans, while a neutral loss scan at 152 u enabled a fast screening of procyanidin dimers, trimers and their galloylated derivatives. The compounds were confirmed by accurate mass measurements in QqToF-MS and QqToF-MS/MS modes at high resolution, and good fits were obtained for all investigated ions, with errors ranging from 0.2 to 4.5 mDa. To the best of our knowledge, two flavanol monomer hexosides were detected in the grape berry for the first time.
