Problems solved by technology

[0004] However, the fat content in fresh chicken intestines is very high, accounting for about 45%-50% of the dry matter content, which affects its nutritional value, and is also prone to oxidation and rancidity, which is not conducive to storage, so if traditional protein powder is used to process The process directly processes the chicken intestines, and it is impossible to obtain the original special ingredients in the raw materials of the chicken intestines, and it is difficult to obtain ideal products
The current slaughterhouses mix chicken intestines with other leftovers of slaughtered chickens for processing, and do not produce and process them as a single product or product raw material. This should be said to be a waste of resources

Embodiment 1

[0022] Take 1,000kg of fresh chicken intestines, mince them into small pieces of 10-15mm, and cook them at 85°C for 30 minutes. Immediately after cooking, perform horizontal centrifugation at 3,600 rpm until the intestinal residues are obtained. and oil soup; the oil soup is centrifuged twice under the condition of 6150 rpm to obtain fine residue, soup and oil, and the above-mentioned intestinal residue, fine residue and soup are fully mixed to obtain a mixed material, the mixed material The concentration of the dry substance substrate is about 20%. Put the mixed material into the enzymolysis tank, adjust its pH value to 7, and add a compound enzyme preparation to it. Composed of neutral protease and alkaline protease, and the addition amount of the compound enzyme preparation is 1.5% of the dry substance substrate concentration in the mixed material. Enzymolysis is carried out at 50°C for 4 hours, then the temperature is raised to 90°C and kept for 10 minutes, and the enzyme i...

Embodiment 2

[0025] Take 1,500kg of fresh chicken intestines, mince them into small pieces of 20-40mm, and cook them at 90°C for 20 minutes. Immediately after cooking, perform horizontal centrifugation at 3,650 rpm until the intestinal residues are obtained. and oil soup; the oil soup is centrifuged twice under the condition of 6280 rpm to obtain fine residue, soup and oil, and the above-mentioned intestinal residue, fine residue and soup are fully mixed to obtain a mixed material, the mixed material The concentration of the dry substance substrate is about 20%. Put the mixed material into the enzymolysis tank, adjust its pH value to 7.5, and add a compound enzyme preparation to it. Composed of neutral protease and alkaline protease, and the addition amount of the compound enzyme preparation is 1% of the dry substance substrate concentration in the mixed material, enzymatic hydrolysis at 50°C for 3 hours, and then heated to 85°C and kept for 20min to carry out enzyme Inactivation;

Abstract

The invention discloses a low-temperature oil-removing production method of chicken intestine membrane protein powder through enzymolysis. According to the low-temperature oil-removing production method, chicken intestines in which the fat content is high relatively are used as raw materials, and the steps of performing low-temperature cooking, performing centrifugation oil removing, performing protease enzymolysis, concentrating materials, performing spray drying and the like are sequentially performed, so that the fat content in the chicken intestines can be greatly reduced, and through enzymolysis, concentration and drying treatment, the protein powder is obtained. The content of peptide protein particularly the content of small peptide in the chicken intestine membrane protein powder is increased, so that digestion and absorption by animals are facilitated; through spray drying, finished products are high in biologicalactivity, golden in color and rich in fragrance. The chicken intestines are used as raw materials to produce the protein powder, so that waste resources can be effectively used, and the derive homology risks existing in the using process of using pig intestines asraw materials can also be reduced. The method provides a new concept for treating poultry scraps. Under the premise that waste is turned into wealth, the protein powder feed raw materials being highin economic value and good in feeding effect can be obtained.

Description

technical field [0001] The invention relates to the field of animal feed preparation, in particular to a low-temperature deoiling production method of enzymatically hydrolyzed chicken intestinal membrane protein powder. Background technique [0002] The problems facing the development of my country's animal husbandry and feed industry are the shortage of high-quality protein feed resources, especially high-quality animal protein resources, and the backward processing technology. In view of the serious shortage of protein feed resources, the development focus should be placed on areas where local resources are relatively concentrated. For example, leftovers (such as chicken intestines) after slaughtering broiler slaughterhouses are one of the good animal protein resources. These raw materials are about There are more than 1 million tons, and about 200,000 tons of animal protein raw materials can be produced after processing. If the processing technology can be improved, spec...
