Method for producing feeding peanut peptide by anaerobic fermentation of peanut meal

Abstract

The invention relates to a method for producing feeding peanut peptides by anaerobic fermentation of peanut meal, which comprises the following steps: respectively preparing bacterial liquid of lactobacillus fermentum, saccharomyces cerevisiae, and bacillus subtillis, mixing peanut meal, corn meal, and potassium dihydrogen phosphate according to a mass ratio of 90:9:0.9:0.1 to prepare solid materials, well mixing the solid materials and mixed bacterial liquid according to a mass ratio of 6:4, performing fermentation, maintaining the fermentation temperature at 37 + / - 2 DEG C for 72-80 hours, when the fermentation is completed, drying the fermented materials till the water content is 11-12%, crushing to 60-70 meshes to obtain the feeding peanut peptides. The invention degrades the protein in the peanut meal into small peptides or amino acids to a great extent, and biodegrades the aflatoxin in the peanut meal; a lot of protease is generated during the fermentation process, and a large amount of lactic acids and a lot of beneficial microorganisms are contained in the product; the fermentation product is a good raw material for feed, and has good application prospects.

Description

Technical field [0001] The invention belongs to the field of peanut meal production of feed materials, and particularly relates to a method for producing peanut peptides for feed by using peanut meal anaerobic fermentation. Background technique [0002] Peanut meal is a product obtained by extracting oil from peanut kernels. Usually, peanut meal is divided into primary meal and secondary meal. The primary meal means the peanut residue left after the primary pressing, and the secondary meal is the peanut residue that has been pressed twice. Usually the output of peanut meal can reach more than 44%, which means that the oil yield of peanuts is more than 55%, so the output of peanut meal is relatively small. Peanut meal is rich in plant protein, has a good taste, and is more suitable for use in aquatic feed for poultry and livestock. [0003] Because peanut meal is very easy to produce aflatoxin when stored, its quality as a feed material is greatly reduced. Summary of the inventio...
