Enzyme for Alcohol (Yeast Promoter) Kumquat alcohol enzyme is an application-type compound enzyme preparation used in the alcohol production process. It can shorten the alcohol fermentation cycle and improve the wine content by providing high-quality nitrogen source to the yeast and improving the utilization of starch. The use of this product in the production process of edible alcohol can partially (or completely) replace urea; Increase the number and germination rate of wine mothers, speed up the fermentation speed, and shorten the fermentation cycle; Improve yeast sugar alcohol conversion ability and increase wine content; Reduce the residual sugar content and reduce the pressure of sewage treatment.
