Problems solved by technology

[0005] Due to the high content of free ammonia in the intestinal mucosa raw materials, if the free ammonia cannot be effectively removed during the production process, the free ammonia content in the intestinal membrane protein powder product will be too high; free ammonia will generate high osmotic pressure in the animal intestine, which will cause Cause diarrhea and even death in piglets
The existing method for removing free ammonia is to use neutralization method, which will generate a lot of sewage. As a result, the cost of wastewater treatment generated in the existing production process of removing free ammonia is very high, and the pressure on environmental protection is huge. These problems must be completely solved

Abstract

The invention discloses a dried porcine soluble product and a production method thereof. The production method of the dried porcine soluble product comprises the following steps of heating an intestinal mucosa solution as a raw material for sterilization, and enabling protein to be flocculated; enabling the heated intestinal mucosa solution to stand in a specially made container to remove a supernatant, and performing concentration; crushing protein tissues, and performing an enzymolysis reaction; performing heating for enzyme denaturalixation, and extracting heparin sodium; performing negative pressure concentration; performing spray drying; and performing packaging. The dried porcine soluble product comprises the following components of water of which the content is 6.0-10.0wt%, crude protein of which the content is greater than or equal to 50.0wt%, crude fat of which the content is smaller than or equal to 3.0wt%, crude ash of which the content is smaller than or equal to 18.0wt%, table salt of which the content is smaller than or equal to 5.0wt%, free ammonia of which the content is smaller than or equal to 1.0wt%, and small peptide which is smaller than 2000 dalton and of which the content is greater than or equal to 10.0wt%, and protein hydrolysate which is greater than or equal to 45.0wt%. According to the dried porcine soluble product and the production method thereof disclosed by the invention, the free ammonia is removed by a standing method, so that the free ammonia in the dried porcine soluble can be effectively removed, besides, waste water cannot be produced, and the treatment cost is low; the supernatant after high-temperature sterilization is used as probiotics solid state fermentation nutrient fluid for soybean meal, so that pollution is not caused, and the sewage treatment cost is reduced.

Description

technical field [0001] The invention belongs to the technical field of feed raw material processing, and relates to an intestinal membrane protein powder product and a production method thereof. Background technique [0002] Intestinal membrane protein powder is an important raw material added to young animal feed, which plays an important role in promoting intestinal development of young animals. The raw material for the production of intestinal membrane protein powder is animal intestinal mucosa. The fresh animal small intestine (hair intestine) in the slaughterhouse will scrape off the small intestine content (intestinal mucosa) when it is processed into semi-finished casings, and the intestinal mucosa is mainly used to extract the biochemical drug heparin sodium. The intestinal membrane protein solution after extracting heparin sodium is the raw material for processing intestinal membrane protein powder. At present, the techniques for extracting heparin sodium from int...
