Method for enzymatic hydrolysis of dried porcine solubles from animal small intestines

Abstract

The invention discloses a method for enzymatic hydrolysis of dried porcine solubles from animal small intestines, and relates to the field of the production of the dried porcine solubles. The method comprises the following steps: (1) pre-processing intestinal mucosa; (2) conducting enzymatic hydrolysis; (3) conducting fine filtration; (4) conducting desalting; (5) conducting concentrating; and (6) conducting spray-drying. The method has the advantages of being reasonable in steps and convenient to operate, the prepared dried porcine solubles are good in quality, high in digestion rate and good in bioavailability, a salt content of the dried porcine solubles is less than 5% and an ash content is less than 10%, the dried porcine solubles are presented in bright yellow, the dried porcine solubles are aromatic in smell and salty and delicious in taste, without hit to teeth, and harmful pathogenic microorganisms can be killed in a production process, so that biological safety is enhanced.

Description

technical field [0001] The invention relates to the production field of intestinal membrane protein powder, in particular to a method for producing enzymatically hydrolyzed intestinal membrane protein powder from animal small intestine. Background technique [0002] Now two methods are widely used in the market to produce intestinal membrane protein powder, one is the salt hydrolysis method, extracting the residue of heparin sodium, and using the residue to produce intestinal membrane protein powder after enzymatic hydrolysis, the intestinal membrane protein powder produced by this method The quality is poor, the salt content is high, it is easy to deteriorate, and it is not suitable for long-distance transportation, and the intestinal membrane protein powder produced by this method is easy to be corrupted during the drying process, and it will bring in sediment when it is naturally dried; the other is the enzymatic hydrolysis method. It can produce intestinal membrane prote...

[0002] Now two methods are widely used in the market to produce intestinal membrane protein powder, one is the salt hydrolysis method, extracting the residue of heparin sodium, and using the residue to produce intestinal membrane protein powder after enzymatic hydrolysis, the intestinal membrane protein powder produced by this method The quality is poor, the salt content is high, it is easy to deteriorate, and it is not suitable for long-distance transportation, and the intestinal membrane protein powder produced by this method is easy to be corrupted during the drying process, and it will bring in sediment when it is naturally dried; the other is the enzymatic hydrolysis method. It can produce intestinal membrane protein powder while producing heparin sodium, but the intestinal mucosa used in the current enzymatic hydrolysis method is generally processed intestinal mucosal powder, and there is no desalination step in the operation process of some enzymatic hydrolysis methods, so that The salt content in the prepared intestinal membrane protein powder is too high
