Two yeasts, composite leavening agent of two yeasts and method for preparing low-alcohol yellow peach beverage

The invention discloses two yeasts, a composite leavening agent of the two yeasts and a method for preparing a low-alcohol yellow peach beverage, and belongs to the technical field of microorganisms. The method solves the problems that the fermented beverage is unbalanced in flavor, insufficient in fragrance and too high in acidity due to the fact that the saccharomyces cerevisiae is independently used for fermentation. After the non-saccharomyces cerevisiae is added, the hansenula polymorpha strain HT106 and the saccharomyces cerevisiae JM9 in the grape juice promote growth mutually, meanwhile, aroma substances richer than those of single-bacterium fermentation can be generated, generation of bad flavor can be reduced, and the fermented beverage is endowed with more coordinated taste and flavor. The invention provides a new method for deep processing of yellow peaches and development of low-alcohol beverages.
