Abstract

The invention discloses a production technology of saccharomyces cerevisiae fermented soybean meal. The production technology comprises the following steps: (1) saccharomyces cerevisiae strain activation; (2) saccharomyces cerevisiae strain liquid culture; (3) saccharomyces cerevisiae strain triangular flask culture; and (4) soybean meal fermentation. The production technology is simple and easy to understand, and the produced soybean meal has the advantages of high crude protein content, reasonable amino acid composition, high animal digestion utilization rate and the like, saccharomyces cerevisiae used in livestock production can save costs, reduce morbidity, and improve the economic benefit, and is helpful to obtain high-quality livestock products.

Description

[0001] technical field [0002] The invention belongs to the production process of soybean meal, in particular to a production process of yeast meal fermented by Saccharomyces cerevisiae. [0003] Background technique [0004] Soybean meal is one of the important feed ingredients in animal husbandry and aquaculture, accounting for 80% to 90% of protein feed. At present, biological fermentation technology is an effective method to improve the quality of soybean meal. The protease produced during the fermentation process decomposes the antigenic protein and macromolecular protein into small peptides and various biologically active substances that can be digested and absorbed by animals. At the same time, soybean protein can be transformed from microorganisms into bacterial protein, which improves the quality of protein. The aroma and sauce flavor produced during the fermentation process have obvious food-attracting effects and improve the palatability of the feed. However, ...
