Method for producing yeast product using high-lactic acid industrial by-product

Abstract

Provided is a method for producing a yeast product using a high-lactic acid industrial by-product. The method comprises the following steps: (1) inoculating an activated yeast strain into a primary seed culture medium for fermentation culture to obtain a primary seed liquid; (2) inoculating the primary seed liquid into a secondary seed culture medium for fermentation culture to obtain a secondary seed liquid; (3) inoculating the secondary seed liquid into a fermentation culture medium for fermentation culture, wherein the fermentation culture medium comprises a high-lactic acid industrial by-product and/or a modified product of the high-lactic acid industrial by-product; and (4) separating the fermentation broth obtained in step (3) to obtain a yeast product, or drying the fermentation broth obtained in step (3) to obtain a yeast product. According to the method, the fermentation process is stable, the production efficiency is high, the product quality is stable, and the industrial application of using a high-lactic acid industrial by-product for producing a yeast is realized.
