Embodiment 1
[0032] The comprehensive utilization method of waste residue and waste liquid in the production of heparin sodium, chondroitin sulfate and SOD animal biochemical products: includes the following process steps:
[0033] Step 1: Use trypsin to catalyze the hydrolysis of waste residues and liquids generated during the production of animal biochemical products to obtain an enzymolysis solution; trypsin is added in an amount of 0.10% by weight, enzymolysis time is 5 hours, and the temperature is 50°C.
[0034] Step 2: Filter the enzymatic hydrolysis solution in the first step with a 100-mesh bag filter, and collect the filter residue and filtrate respectively; among them, the filter residue is a crude protein product with a protein content of 5% or more; the filtrate is subjected to subsequent microfiltration processing deal with.
[0035] The third step: the filtrate collected in the second step is concentrated by microfiltration with a 0.05 μm microfiltration membrane, and the co...
Embodiment 2
[0042] The comprehensive utilization method of waste residue and waste liquid in the production of heparin sodium, chondroitin sulfate and SOD animal biochemical products: includes the following process steps:
[0043] Step 1: Use trypsin to catalyze the hydrolysis of waste residues and liquids generated during the production of animal biochemical products to obtain an enzymolysis solution; trypsin is added in an amount of 0.15% by weight, enzymolysis time is 3 hours, and the temperature is 30°C.
[0044]Step 2: Filter the enzymolysis solution in the first step with an 80-mesh bag filter, and collect the filter residue and filtrate respectively; among them, the filter residue is a protein crude product above 80 mesh, and its protein content is 6%; the filtrate is subjected to subsequent microfiltration processing deal with.
[0045] The third step: the filtrate collected in the second step is concentrated by microfiltration with a 0.8 μm microfiltration membrane, and the conce...
Embodiment 3
[0052] The comprehensive utilization method of waste residue and waste liquid in the production of heparin sodium, chondroitin sulfate and SOD animal biochemical products: includes the following process steps:
