Synergistic enhancement of bio-yogurt properties by Lactiplantibacillus plantarum NUC08 and mulberry fruit extract

Lactiplantibacillus plantarum NUC08, a novel probiotic strain, has demonstrated potential for synergistic fermentation with starter cultures. This study investigates its functional properties in fermented milk and examines how mulberry fruit extract (MFE), rich in bioactive compounds, may influence its fermentation performance. MFE significantly boosted LAB growth, improved texture and rheological properties, and enhanced antioxidant capacity in the probiotic yogurt. GC-MS analysis revealed that MFE enriched the flavor profile by increasing key flavor-related metabolites, contributing to superior sensory qualities. Furthermore, the combination of L. plantarum NUC08 and MFE led to distinct shifts in metabolic pathways, as shown by LC-MS analysis, amplifying the regulatory effects on antioxidant activity. These findings demonstrate the synergy between MFE and L. plantarum NUC08, where MFE enhances the growth and functionality of L. plantarum NUC08, improving the yogurt's physicochemical properties, antioxidant capacity, and flavor, with potential for functional dairy product development.

Controlled synthesis of distiller's grains biochar for turbidity removal in Baijiu

Resource utilization of distiller's grains (DGs) is crucial for realizing sustainable development of Baijiu industry. In the prevent investigation, a low-cost activated biochar (DGABC) suitable for removing turbidity from low-alcohol Baijiu was prepared by the controlled pyrolysis of DGs, followed by steam activation. The as-prepared biochar featured a large specific surface area (320-480 m²/g) and pore volume (0.45-0.47 cm³/g). Importantly, the DGABC possessed remarkable exterior hydrophily and interior lipophilicity, which guaranteed its good dispersion in alcohol-water system as well as an efficient adsorption to the components with long lipophilic chain. As a result, the DGABC could efficiently remove the turbidity in low-alcohol Baijiu, which was mainly derived from the long lipophilic chain components, such as ethyl palmitate. Meanwhile, most of the flavor esters that had a shorter lipophilic chain and lower hydrophobicity were well kept in the low-alcohol Baijiu. Therefore, this work provided a promising strategy for DGs recycling in Baijiu industry.
