Article Abstract
has been extensively studied for its ability to inhibit the growth of harmful microorganisms and its high protease activity. In this study, was used to ferment gluten and assess the effects of the fermentation process on the physicochemical, microstructure and antioxidant properties of gluten. The results of Fourier infrared spectroscopy (FT-IR) and circular chromatography (CD) showed a significant decrease in the content of α-helix structures and a significant increase in the content of β-sheet structures in gluten after fermentation ( < 0.05). Sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE) showed that glutenin was degraded into small molecular peptides with a molecular weight of less than 26 kDa after 24 h of fermentation; meanwhile, the fermentation process significantly increased the free amino acid content of the samples ( < 0.05), reaching 1923.38 μg/mL at 120 h of fermentation, which was 39.46 times higher than that at 24 h of fermentation ( < 0.05). In addition, the fermented back gluten has higher free radical scavenging activity and iron reduction capacity. Therefore, fermented gluten may be used as a functional food to alleviate oxidative stress. This study provides a reference for the high-value application of gluten.

A novel and efficient hydrogen peroxide/ascorbic acid-assisted extraction method for the preparation of Grifola frondosa polysaccharide (GFP) was developed, and two GFP fractions (GFP-H and GFP-L) with different molecular weights (Mws) were obtained by separation with ultrafiltration. Both high Mw component (GFP-H, Mw 396.4 kDa) and low Mw component (GFP-L, Mw 12.

This research study investigates the relationship between the structural characteristics, water solubility, and protein digestibility of quinoa proteins (QPs) during fermentation. The fermentation process induces structural modifications in QPs, thereby enhancing their surface properties and functional attributes. Using advanced analytical techniques, such as ultraviolet, fluorescence, and FT-IR spectra, it has been demonstrated that fermented QPs exhibit significant structural changes (P < 0.

Unlabelled: This study explored the impact of green tea addition on bacterial communities in Moutai-flavored fermentation using high-throughput sequencing, alongside physicochemical and flavor analysis. Significant differences in microbial succession were observed over the 40-day fermentation period among types with varying tea proportions, resulting in distinct bacterial communities. Sixteen dominant genera, including , , and , were identified, with their relative abundances and succession patterns varying by type.

White sour soup (WSS) is a traditional fermented food from Guizhou, China. To address the issues of long fermentation cycles, inconsistent quality, and safety risks, this study screened core strains based on microbial diversity. Analysis of 20 WSS samples revealed , , and as dominant genera, with eight harmful microorganisms detected in naturally fermented samples.
