Novel process for machining intestinal membrane protein

Abstract

The invention discloses a novel process for machining pig and sheep intestinal membrane protein. The process comprises the following steps: purchasing fresh pig and sheep pancreas, duodenum and gall bladder from a slaughter house every day; washing; preserving at a low temperature for later use; smashing the pancreas, the duodenum and the gall bladder together in a stamp mill; adjusting the moisture of the intestinal membrane protein to be subjected to enzymolysis to be 70-86%; subsequently heating to 86-95 DEG C and keeping the temperature for 20min; further introducing circulation cooling water to cool to 33-40 DEG C and keeping the temperature; adjusting pH value to 7-9 by using baking soda; putting the smashed pancreas mixture into an enzymolysis tank in a percentage of 1%; constantly stirring at a slow speed (2 cycles/minute) at 37 DEG C for 2 hours; and puffing the intestinal membrane protein at 110-130 DEG C by using a wet method. The intestinal membrane protein which is subjected to enzymolysis and puffing is mixed in a ratio of 1:3, and is dried up. According to the process, rich intestinal membrane protein resources are utilized and machined in an enzymolysis and puffing mode, so that the molecular structure of a product is loose, the ratio of low molecular peptide protein and free amino acid obtained from enzymolysis is greatly increased, and the product is sterilized and disinfected, so that the novel, efficient and safe process for machining the intestinal membrane protein is realized ultimately.

Description

technical field [0001] The invention relates to a new process for processing pig and sheep intestinal membrane proteins, belonging to the field of development and utilization of animal-derived protein raw materials in the feed industry. Background technique [0002] Protein resource is one of the leading ones in the feed industry. The scientific and rational utilization of scarce protein resources is the key to the development of feed industry and breeding industry. Intestinal membrane protein, as a by-product of casing export processing and heparin extraction, because of its wide range of sources, about 50,000 tons of output in the country every year and a dry matter crude protein content as high as 60%, has been used by the feed industry and aquaculture for more than ten years industry is widely used. However, due to the simple and extensive treatment and the lack of processing technology, the intestinal membrane protein circulating in the market has been generally spoil...
