Abstract

The invention discloses a method for preparing rumen-protected gelatinized soybean meal by utilizing high-pressure-assisted microwave puffing. The method comprises the following steps: performing intermittent high-pressure pretreatment on soybean meal under the pressure of 50-100Mpa; performing preparation reaction on soybean meal protein and glycolipid; and uniformly stirring the prepared and reacted soybean meal and glycolipid mixture through a homogenizer, feeding the mixture into a microwave bulking machine at a constant speed, and performing bulking for 5-10 minutes under the conditions that the microwave power is 600W and the temperature is 60 DEG C, so that the soybean meal is gelatinized and bulked, and rumen-protected gelatinized soybean meal is obtained. The prepared rumen-protected gelatinized soybean meal can promote the rumen-protected effect of the soybean meal, reduce the degradation rate of protein of the soybean meal in the rumen and improve the small intestine digestion efficiency of the soybean meal.

Description

technical field [0001] The invention relates to the technical field of feed processing, in particular to a method for preparing rumen-passed gelatinized soybean meal by using high-pressure assisted microwave puffing. Background technique [0002] Soybean meal is a kind of high-quality plant protein, which is widely used in protein supplement feed for various ruminants. However, these botanical proteins are easily degraded in the rumen of ruminants, and microbial proteins are synthesized by microorganisms. The degradation rate of these proteins in the rumen can reach up to 60%, affecting the digestion and absorption in the small intestine, resulting in a certain degree of waste. Therefore, certain treatment measures should be taken to increase the rumen passing rate of soybean meal, so that the protein flowing into the small intestine can be increased, and the utilization efficiency of soybean meal can be improved. Rumen-passing protein (RUP) refers to the protein in the ru...
