Abstract

The invention discloses a method of producing feed having a high small-peptide content by biological fermentation of cottonseed meal, and belongs to the technical field of biological fermentation. The method adopts the cottonseed meal as a raw material. A lactobacillus acidophilus liquid and a yeast seed liquid are added. The material-liquid ratio is 1:0.6-1:0.9. Solid-state fermented cottonseed meal is obtained by performing anaerobic fermentation at 30-50 DEG C for 3-4 days, drying and smashing. The method adopts solid state fermentation, and is simple in process and low in cost. A finished product of the fermented cottonseed meal is reddish, is rich in lactic acid, various digestive enzyme, vitamins and small peptides, and has a large amount of probiotics and rich and mellow fragrance of distiller's yeast. Oxidation resistance of the product is largely enhanced that of the raw material. After fermentation, the content of gossypol is lower than 50 mg / Kg, and main mycotoxins are not detected. The feed is capable of promoting animal ingestion and boosting animal immunity and is safe and absorbable.

Description

Technical field: [0001] The invention relates to a method for producing high-small-peptide feed by biologically fermenting cotton dregs, in particular to producing a bio-fermentation product that induces food, promotes digestion, improves immunity and detoxifies by using Lactobacillus acidophilus and yeast to ferment cotton dregs A method for producing high-small peptide feed by biologically fermenting cottonseed meal. Background technique: [0002] Cotton meal is a cake obtained after cottonseed is pressed, and then most of the residual oil is separated through leaching process to obtain a reddish or yellow granular product. The annual output of cotton meal in my country is 5 to 7 million About tons, wide source, low cost. Since cottonseed meal contains a large amount of anti-nutritional factors, it has not been effectively utilized. At present, it is mainly used as primary raw material for feed industry. [0003] Cotton meal is rich in nutrients, including protein, crude...
