Biogenic amines (BAs), products of microbial decarboxylation, are found in a range of foods. Toxicity-wise, histamine and tyramine are paramount among all BAs. Employing amine enzymes, such as multicopper oxidase (MCO), is a potent approach to diminishing the levels of bile acids (BAs) present in food systems. This research scrutinized the heterologous expression and characterization of MCO from Lactobacillus sakei strain LS. At 25°C and pH 30, the optimal temperature and pH for recombinant MCO (rMCO), using the typical substrate 22'-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) (ABTS), resulted in a specific enzyme activity of 127 U/mg. Further research explored the impact of diverse environmental factors on the degradation processes initiated by MCO concerning two types of BAs. The degradation capabilities of rMCO are independent of any externally supplied copper or mediating components. The oxidation ability of rMCO concerning histamine and tyramine benefited from the higher concentration of NaCl. rMCO's amine-oxidizing ability can vary significantly depending on the type of food matrix involved. Even though rMCO's histamine-degrading capacities were diminished, it reached a degradation rate of 281% when combined with surimi. The tyramine degradation activity of rMCO was amplified by up to 3118% when treated with grape juice. Due to its inherent characteristics, rMCO is a compelling candidate for the breakdown of harmful biogenic amines in food environments.
Tryptophan metabolites originating from the microbiota are crucial for upholding intestinal equilibrium, yet the potential role they play in shaping gut microbial communities has been understudied. The results of this study revealed a remarkable finding: Lactiplantibacillus plantarum ZJ316 (CCTCC No. M 208077) exhibited superior production of indole-3-lactic acid (ILA), achieving a level of 4314 g/mL. ILA, with an exceptional purity of 9900%, was synthesized by combining the methods of macroporous resin, Sephadex G-25, and reversed-phase high-performance liquid chromatography. Purified ILA acts as an effective inhibitor of foodborne pathogens, encompassing Salmonella spp., Staphylococcus spp., Escherichia coli, and Listeria monocytogenes. Using an in vitro model of the human gut microbiome, a medium dose (172 mg/L) of ILA led to a 927% and 1538% increase in the relative abundance of Firmicutes and Bacteroidota respectively, and a 1436% reduction in Proteobacteria after 24 hours of fermentation. Analysis at the genus level revealed a substantial increase in the relative abundance of Bifidobacterium to 536,231% and Faecalibacterium to 219,077%, both statistically significant (p<0.001). Significantly decreased levels of Escherichia and Phascolarctobacterium were measured, reaching 1641 (a 481% reduction) and 284 (a 102% reduction), respectively (p < 0.05). In the intestine, a substantial increase (298,072 mol/mL, p<0.005) in short-chain fatty acids, specifically butyric acid, demonstrated a positive correlation with the presence of the bacteria Oscillospira and Collinsella. Conclusively, ILA displays the potential to influence the gut microbiota, and a more comprehensive investigation into the connection between tryptophan metabolites and the gut microflora is necessary for future research efforts.
Food is currently recognized not only for its role in providing essential nutrients, vitamins, and minerals, but also for its bioactive compounds, which demonstrably contribute to disease prevention and dietary treatment.

The study evaluates the impact of ferulic acid-grafted chitosan (FA-g-CS) on the binding of anthocyanins (ANC) to sGLT1/GLUT2 transporters and their involvement in anthocyanin transport across cell membranes, using Caco-2 cells. The transport efficiency (Papp 80%) of ANC in transmembrane transport experiments was found to be considerably lower than that observed with solely FA-g-CS or ANC (fewer than 60%). Molecular docking experiments show a robust interaction of FA-g-CS/ANC with either sGLT1 or GLUT2, indicating a strong binding potential. The findings underscore how FA-g-CS facilitates ANC's transmembrane transport by modulating the ANC-sGLT1/GLUT2 interaction; a crucial element in enhancing ANC bioavailability may be the interaction between FA-g-CS and ANC.
Nutritional and therapeutic benefits are conferred by cherries' bioactive compounds, characterized by strong antioxidant activity. Cherry wines prepared with mild and concentrated green tea infusions were the subject of biological property analysis in this study. Winemaking procedures involved the determination of key parameters, including alcohol levels, reducing sugars, acidity, and total polyphenol content, as well as biological properties like antioxidant activity and the potential for inhibiting alpha-glucosidase. The impact of the gastrointestinal system on the biological stability of the wines, and the interactions of the wines with the intestinal microflora, were also investigated using an in vitro digestion process. Compared to the control wine, the introduction of green tea into the cherry wine led to a marked increase in total polyphenol content, escalating to 273 g GAE/L, and a substantial elevation in antioxidant activity, reaching as high as 2207 mM TE/L. Despite the initial presence, in vitro digestion led to a decrease in both total polyphenol levels (53-64%) and antioxidant efficacy (38-45%). The growth of intestinal microorganisms, particularly E. coli, was more effectively hindered by fortified wines supplemented with green tea. The potency of alpha-glucosidase inhibition was appreciably enhanced by the bioactive compounds derived from tea. A promising alternative wine type, the proposed wines could enhance polyphenol levels, potentially impacting insulin response favorably in diabetes management.
