Summary: Solid-state fermentation of whole grain wheat with Agaricus brasiliensis and Agaricus bisporus led to a significant increase in polyphenol content and notable changes in phenolic compound composition. Fermented wheat exhibited stronger antioxidant properties compared to the control, as evidenced by enhanced DPPH radical scavenging capacity, reducing power, ferrous ion chelating ability, and inhibition of lipid peroxidation.

Summary: This study examined the release of bioelements and phenolic compounds from edible mushrooms enriched with zinc, selenium, and L-phenylalanine, both individually and in combination, through a simulated human gastrointestinal digestion method. The results indicated that mycelium of Lentinula edodes showed the best health-promoting properties, with significant increases in the synthesis of p-hydroxybenzoic and protocatechuic acid when a mixture was added. Additionally, enriched Agaricus bisporus mycelium had the highest extraction amounts of selenium and zinc.

Summary: The relationship between fruit position, ripening stage, and variety was examined in pepper plants, showing that capsaicin content was mainly influenced by genetics, while total phenolic content, total flavonoid content, and antioxidant activity were more affected by the ripening stage and fruit position. Ripening stage had a significant impact on various agronomic traits. Variety, fruit position, and ripening stage effects were more significant than interactions among these factors.

Summary: The polyphenols of ten Moroccan apricot clones were analyzed to evaluate their evolution pattern and contribution to antioxidant activity during ripening. Procyanidins were the predominant polyphenol class and played a crucial role in the antioxidant activity of the apricots. The impact of ripening on fruit size and skin color was limited. Thioacidolysis-UFLC technology highlighted the contribution of procyanidins and established a typology based on clone skin color.

Summary: The purpose of this study was to investigate the inhibition of fat absorption by four popular yerba mate beverages. The results showed that all extracts had similar effects in reducing triglyceride absorption at the same dosage, while no significant effect was observed on starch absorption. Pancreatic lipase was strongly inhibited by the hot and room temperature-water extracts, but less strongly by mate tea and instant mate. The most important inhibitors were found to be mono- and di-caffeoylquinic acids.

Summary: This study investigates the variations in lipid digestion profiles among individuals of different ages using in vitro digestion models. The findings suggest that adults have a more comprehensive lipid digestion compared to infants, and infants tend to release shorter chain length and more saturated free fatty acids during digestion. Additionally, the particle sizes in the stomach of the elderly were consistently larger. This study enhances our understanding of how lipids with different degrees of unsaturation undergo digestion in diverse age groups.

Summary: This study investigated the acidification of aroma-enhanced black tea during storage. Analysis of non-volatile substances and organic acids using UPLC-Q-TOF/MS and HPLC revealed a decrease in soluble sugars and amino acids, while an increase in organic acids such as oxalic acid, malic acid, and quinic acid. In vitro experiments further demonstrated that the acidification is a result of the decomposition of sugars and amino acids by heating, as well as the oxidation of aromatic aldehydes. Additionally, the study showed that the taste composition of tea infusion is altered, with reduced amino acids, catechins, soluble sugars, and flavonoids. This research provides a theoretical basis for improving the quality of black tea.
