Abstract

The invention provides a yeast food, which can provide yeasts with nutrients for fermentation. The yeast food comprises the following components by weigh portion: 40 to 75 portions of nitrogen source, 15 to 25 portions of phosphor source, 8 to 15 portions of other inorganic salts and 2 to 5 portions of minor vitamins. The yeast food can prolong the stable growth period of yeasts and can be added into fermented liquor deficient in nutrients to promote the quick growth and active fermentation of the yeasts. The yeast food is an indispensible novel accessory for wine industry and alcohol industry.

Description

technical field [0001] The invention relates to microorganism culture technology, in particular to a nutrient substance specially provided for the growth of yeast. Background technique [0002] At present, with the development of microbial process technology, more and more products are produced by fermentation of strains, especially foods fermented by yeast. For example, the production of alcohol and liquor is the process of converting reducing sugars such as glucose and fructose after the conversion of raw materials into alcohol through the alcoholic fermentation of yeast. Therefore, in order to make alcoholic fermentation proceed normally, it is necessary to ensure that there are sufficient nutritional conditions for the growth of yeast in the fermentation medium. In actual production, due to the poor quality of raw materials, improper process treatment or the influence of yeast metabolites, the mortality of yeast in the middle and late stages of alcohol fermentation incr...
