Objective To explore the optimal fermentation process of Vatica wine and analyze its flavor substances. Methods The fermentation conditions of Vatica wine were optimized by single factor experiments and Box-Behnken response surface analysis. The effects of yeast addition amount, fermentation temperature and fermentation time on the fermentation of green plum wine were analyzed. The flavor components of green plum wine were analyzed by headspace solid-phase microextraction and gas chromatography-mass spectrometry to determine the optimal process conditions. Single-factor experiments. Results The optimal technological conditions were as follows: Fermentation temperature 25 ℃, yeast addition 0.5 g/L, fermentation time for 8 days. Among them, 25 kinds of volatile flavor substances were detected. The main flavor active ingredients were alcohols, esters, aldehydes and ketones, terpenes, etc. They accounted for 59.28%, 9.07%, 17.00% and 0.96% of flavor substances, respectively. Conclusion The Vatica wine fermented by this condition is sweet and sour and has the unique fragrance of Vatica, which provides theoretical support for the industrialization upgrading and quality improvement of Vatica wine.
