Preparation method of intestinal membrane protein powder

Abstract

The invention discloses a preparation method of intestinal membrane protein powder, comprising the following steps: (1) cutting fresh chicken intestines into chicken intestine crumbs, grinding the chicken intestine crumbs to prepare chicken intestine raw material slurry after cleaning; (2) deoiling the chicken intestine raw material slurry prepared in the Step (1); (3) deodorizing the chicken intestine raw material slurry; (4) homogenizing the material; 5) carrying out enzymatic hydrolysis treatment on that material; and 6) spray-drying. By the preparation method of the invention, the chickenintestine by-product in slaughterhouses can be efficiently utilized, and the chicken intestine is made into an intestinal membrane protein product. By feeding pigs with the intestinal membrane proteinproduct prepared from chicken intestines, the hidden danger of homologous biological safety is greatly reduced. The intestinal membrane protein product has no impurities, removes grease, has long storage time, high content of small peptides, greatly eliminates the original odor, improves the sensory sense of the product and the feeding habit of pigs, has low production cost, and is beneficial toenvironmental protection.

Description

technical field [0001] The invention belongs to the technical field of feed raw material processing, and in particular relates to a preparation method of intestinal membrane protein powder. Background technique [0002] Intestinal membrane protein is a new type of high-quality nutritional animal protein source, rich in small peptides and free amino acids, with high digestibility and digestibility, it can be used in the feed of early weaned piglets, which can promote the development of the gastrointestinal tract of piglets and improve Piglet digestive tract enzyme activity, improve piglet immunity, thereby improving piglet growth performance. [0003] At present, most intestinal membrane protein powders on the market are pig intestinal membrane protein products. As we all know, the raw material of pig intestinal membrane protein is "waste residue or waste liquid after extracting heparin sodium from pig small intestine". The source of raw materials is different and the quality...

AI Technical Summary

Problems solved by technology

The output of heparin sodium by-products from a single manufacturer is limited. To obtain a large amount of intestinal membrane protein powder raw materials, raw materials must be purchased from many manufacturers. However, different manufacturers have different processing methods, and the level of product control is also uneven, which aggravates the instability of the product

[0004] At the same time, attention must also be paid to the potential safety hazards of the homology of porcine intestinal membrane proteins. The use of porcine intestinal membrane proteins to feed pigs cannibalism will greatly increase the risk of contracting diseases from individuals of the same species

[0005] my country is a big country for raising chickens. During the slaughtering of broilers, a large amount of chicken intestines will be produced, and these chicken intestines are the raw materials for making high-quality intestinal membrane protein. First, chicken intestines have not been effectively utilized, and second, the side of conventional chicken intestine production There are many impurities in the protein product, which affects the overall quality of the product, and the oil content in the product is high, and the oil is prone to rancidity, which affects the quality of the product, and also makes the overall protein content of the product not high. On the other hand, chicken intestinal membrane protein powder smells Larger, affecting product sensory and pig feed intake
