Abstract
Advanced glycation end products (AGEs) can be caused during a glycoxidation reaction. This reaction is associated with complications of diabetes and the consequences of health problems. Therefore, we are exploring the prohibitory effect of highland barley protein hydrolysates (HBPHs) on AGE formation. Herein, first extracted the protein from highland barley with various pH conditions and then hydrolyzed using four different proteolytic enzymes (flavourzyme, trypsin, papain, pepsin) under different degrees of hydrolysis. We assessed three degrees of hydrolysates (lowest, middle, highest) of enzymes used to characterize the antioxidant activity and physicochemical properties. Among all the hydrolysates, flavourzyme-treated hydrolysates F-1, F-2, and F-3 indicated the high ability to scavenge DPPH (IC50 values of 0.97 %, 0.63 %, and 0.90 %), structural and functional properties. Finally, the inhibitory effect of the most active hydrolysates F-1, F-2, and F-3 against the AGEs formation was evaluated in multiple glucose-glycated bovine serum albumin (BSA) systems. Additionally, in a BSA system, F-3 exhibited the strong antiglycation activity, effectively suppressed the non-fluorescent AGE (CML), and the fructosamine level. Moreover, it decreased carbonyl compounds while also preventing the loss of thiol groups. Our results would be beneficial in the application of the food industry as a potential antiglycation agent for several chronic diseases.

Assessment of the Physicochemical, Antioxidant, Microbial, and Sensory Attributes of Yogurt-Style Products Enriched with Probiotic-Fermented Aronia melanocarpa Berry Juice. Foods 2023; 13:111.

Abstract
The aim() of this study was to create() various formulations of yogurt enriched with freeze()-dried adjuncts, namely() (i) probiotic Lactobacillus plantarum ATCC 14917 culture(), and (ii) L. plantarum ATCC 14917 fermented black chokeberry juice, along with a commercial() starter culture(). The goal was to enhance() functionality and optimize the nutritional() value() of the products. These new yogurt-style() formulations were subsequently() compared with commercially produced yogurt. All products demonstrated() favorable() physicochemical properties, and the probiotic strain() consistently() maintained viable() levels exceeding 7 log() cfu/g throughout() the entire() storage() period(). The fermented milk produced with the adjunct-free L. plantarum cells, as well as the yogurt produced with the proposed() lactobacilli-fermented chokeberry juice, exhibited the highest lactic acid() production() (1.44 g/100 g yogurt by the end of storage()). Levels of syneresis were observed at lower() values() in yogurt produced with freeze()-dried fermented chokeberry juice. Yogurts prepared() with the lactobacilli-fermented freeze()-dried chokeberry juice displayed elevated total() phenolic content() and antioxidant capacity() (25.74 µg GAE/g and 69.05 µmol TE/100 g, respectively()). Furthermore, sensory tests revealed a distinctive() fruity flavor() in samples incorporating fermented juice. The results demonstrate() that probiotic L. plantarum-fermented chokeberry juice enhances() both the antioxidant capacity() and the viability of beneficial() bacteria() in yogurt while it can be readily() applied and commercialized, especially in the form of a freeze()-dried formulation.

Impact of a novel probiotic Lactobacillus strain isolated from the bee gut on GABA content, antioxidant activity, and potential cytotoxic activity against HT-29 cell line of rice bran. JOURNAL OF FOOD SCIENCE AND TECHNOLOGY 2022; 59:3031-3042.

Abstract
UNLABELLED Rice bran was fermented with Lactobacillus apis, isolated from the bee gut as a novel probiotic strain, and Saccharomyces cerevisiae to investigate the relationship between its metabolites and antioxidant activity, nutraceutical value, and cytotoxic activity against the HT-29 cell line. The findings showed that L. apis improved the antioxidant activity (DPPH of 37.73%) and antioxidant capacity (ABTS of 37.62 mg Trolox/g,), as well as, hydroxyl radical-scavenging activity (91.55%) of rice bran compared to S. cerevisiae. The metabolic analysis of volatile compounds revealed an increase of alcohols and lactones in the samples fermented with S. cerevisiae. While the samples fermented with L. apis displayed an increase of ketones, esters, and thiazoles. On the other hand, L. apis and S. cerevisiae exhibited a significant ability to increase γ-aminobutyric acid during different fermentation times. Compared with non-fermented samples (18.54%), L. apis increased the cytotoxic activity of rice bran against the HT-29 cell line to 34.17%, and S. cerevisiae to 31.34%. These results suggest that the fermentation of rice bran with S. cerevisiae and L. apis provides a promising strategy to improve the antioxidant activity and nutraceuticals of rice bran, and a potential source for plant-based pharmaceutical products.
