Tracking the dynamic changes of a flavor, phenolic profile, and antioxidant properties of Lactiplantibacillus plantarum- and Saccharomyces cerevisiae-fermented mulberry wine.

The process of fermentation renders the superior quality of mulberry wine based on the microorganisms utilized. The present study aimed at investigating the changes and correlation between phenols and product quality of mulberry wine fermented with Lactiplantibacillus plantarum and Saccharomyces cerevisiae combinatorially. Total anthocyanins concentration (TAC), polyphenols concentration (TPC), flavonoids concentration (TFC), and antioxidant capacity decreased significantly with high correlation in the fermentation process. TAC gradually reduced with a loss rate of 47.98% from 0 to third day of fermentation. Fermented mulberry wine obtained indicated a dynamic balance due to the presence of p-hydroxybenzoic acids as compared to the primary phenolic constituent. Chlorogenic acid usually presents in mulberry juice. The relative intensity of sourness was the most prominent and reached the maximum (10.93) on day 2 of fermentation. A total of 21 volatile esters were quantified (6621.59 μg/L), which contributed significantly to the aroma of mulberry wine. The enhanced quality of fermented mulberry wine showed contraindications with decreased constituents and escalated wine quality. Rather than usual single inoculum, fermentation combination of LAB and yeast holistically influenced the color, taste, fragrance, phenolic profiles, and antioxidant properties in mulberry wine, ensuring palatability and fit for commercialization prospects.
