Embodiment 1

[0021] Example 1: Take heparin sodium raffinate and filter it through 180-mesh nylon cloth to remove impurities. The heparin sodium raffinate after impurity removal is desalted and dehydrated by nanofiltration membrane equipment. The working temperature is 25°C and the pressure is 1.5MPa. Measure the protein content of the concentrate after concentration, make a solution with a substrate concentration of 4%, add a compound animal proteolytic enzyme with a substrate protein weight of 5.0‰ to the solution, adjust the pH value to 8.0, and perform enzymatic hydrolysis at a constant temperature of 50°C 6h. After the enzymolysis is finished, add 40% of the weight of the substrate wheat bran into the enzymolysis solution, completely dissolve and stir evenly. Spray-dry the enzymatic hydrolysis solution added with the carrier, the air inlet temperature of the spray drying is 180°C, and the air outlet temperature is 90°C. After spray drying, a golden yellow intestinal membrane protein ...

Embodiment 2

[0022] Example 2: Take heparin sodium raffinate and filter it through 180-mesh nylon cloth to remove impurities. The heparin sodium raffinate after impurity removal is desalted and dehydrated by nanofiltration membrane equipment. The working temperature is 20°C and the pressure is 2MPa. Measure the protein content of the concentrate after concentration, make a solution with a substrate concentration of 5.5%, add a compound animal proteolytic enzyme with a substrate protein weight of 6.0‰ to the solution, adjust the pH value to 7.5, and perform enzymatic hydrolysis at a constant temperature of 55°C 7h. After the enzymolysis is finished, wheat bran with 50% weight of the substrate is added to the enzymolysis liquid, completely dissolved and stirred evenly. Spray-dry the enzymatic hydrolysis solution added with the carrier, the air inlet temperature of the spray drying is 185°C, and the air outlet temperature is 85°C. After spray drying, a golden yellow intestinal membrane prote...

Abstract

The invention relates to a process for preparing intestinal membrane protein powder by utilizing residual liquid sourced from heparin sodium production, which comprises the following steps of: (1) raw material pretreatment: filtering heparin sodium residual liquid by nylon cloth of 180 meshes for removing impurities; (2) raw material desalination and dehydration: desalinating and dehydrating raw materials by the heparin sodium residual liquid obtained, after impurity removal, through nanofiltration membrane equipment; (3) enzymolysis: adding composite animal protein hydrolase which is 0.2-0.8 percent by substrate weight into the heparin sodium residual liquid with the substrate concentration of 3-6 percent, adjusting the pH value to 7.0 to 8.5 and carrying out enzymolysis at the constant temperature of 50-60 DEG C for 4-8 hours; (4) carrier addition: adding wheat bran which accounts for 20-50 percent by substrate weight into enzymolysis liquid, completely dissolving and uniformly stirring; and (5) spraying and drying. The method has the advantages of simple process, low cost, enzymolysis thoroughness, high product yield and high product quality, can be used for reducing the environmental pollution, changing the waste materials into valuable things and reducing the production energy consumption and the production cost.

Description

Technical field: [0001] The invention relates to a preparation process of feed and animal-derived feed in the field of animal husbandry, in particular to a process for preparing intestinal membrane protein powder by using heparin sodium residue. Background technique: [0002] Intestinal membrane protein powder is a kind of nutritional polypeptide feed rich in protein, amino acid, oligopeptide, calcium, phosphorus, cellulose and some other macro and trace elements. Intestinal membrane protein powder is easily digested and absorbed by animals, and can be used in weaned piglets, sows and aquaculture. Due to the research progress of animal protein nutrition theory, the theoretical research, development and utilization of peptide feed have become a research hotspot in the recent period. Many people pay attention to the role of peptide feed in animal protein nutrition, especially the application in the production of weaned piglets. sex studies. Small peptide nutrition theory is ...
