Problems solved by technology

[0009] Aiming at the deficiencies of the prior art, the present invention provides an alcohol fermentation accelerator using soybean protein hydrolyzate, compound yeast nutrients and surface active substances as raw materials, aiming at solving the needs of yeast growth and reproduction in alcohol fermentation, especially high-concentration fermentation. The lack of nutrients and the inhibition of yeast production by osmotic pressure, alcohol concentration, and yeast metabolic by-products during the fermentation process lead to incomplete alcohol fermentation and long fermentation cycles.

Abstract

The invention belongs to the field of alcoholic fermentation technology, and relates to an alcoholic fermentation promoter, and a preparation method and applications thereof. The alcoholic fermentation promoter comprises, by weight, 85 to 99 portions of soybean protein hydrolysate, 0.2 to 12 portions of a surface active material and 0.2 to 5 portions of yeast composite nutriment. The alcoholic fermentation promoter is capable of promoting rapid growth and propagation of yeast, and improving adaptabilities of yeast on severe environment such as high temperature, high alcohol concentration and high osmotic pressure; is suitable for alcoholic fermentation, and especially for high-concentration mash fermentation of alcohol; and is capable of increasing alcoholic fermentation speed effectively, shortening alcoholic fermentation period, and increasing alcohol yield and utilization rate of raw materials.

Description

technical field [0001] The invention belongs to the technical field of alcohol fermentation, and relates to an alcohol fermentation accelerator and its preparation method and application method. Background technique [0002] The alcohol industry is a basic raw material industry, and its products are widely used in food, chemical, military, pharmaceutical and other fields. In the new technology of alcohol utilization, ethanol gasoline can also be formed by mixing with ordinary gasoline in a certain proportion. With the continuous rise of global oil prices and the implementation of sustainable development strategies, ethanol alcohol, as a renewable energy source, has a huge market demand. [0003] Alcohol is mainly made of starch (cassava, potato, corn, rice, etc.) and sugar (molasses, sugar cane, sweet sorghum, etc.) as raw materials. have to. At present, the alcohol fermentation method commonly used by alcohol production enterprises is thick mash fermentation, that is, hig...
