Effect of mixed fermentation (Jiuqu and Saccharomyces cerevisiae EC1118) on the quality improvement of kiwi wine.

The aim of this study was to investigate the effect of mixed fermentation of Jiuqu and Saccharomyces cerevisiae on the quality of kiwifruit wine. The results showed that total titratable acidity, methanol and organic acids of kiwi wine fermented by Jiuqu + Saccharomyces cerevisiae EC1118 were significantly lower (p < 0.05) than that in other groups. There was no significant difference in the content of flavor substances in kiwi wines fermented by a mixed group and Saccharomyces cerevisiae EC1118 alone, but the sensory evaluation showed a significantly large difference. On the sensory scale, kiwi wine fermented by mixed fermentation had a unique presentation and typical bouquet, better than those fermented by Jiuqu and Saccharomyces cerevisiae EC1118 alone. In conclusion, mixed fermentation of Jiuqu + Saccharomyces cerevisiae EC1118 could improve the quality of the kiwi wine, which provides a promising application prospection for kiwi wine production.
