| titleOfInvention | A method for preparing collagen peptides from chondroitin sulfate ultrafiltration waste liquid |
| abstract | The invention provides a method for the co-production of high-purity collagen peptide with chondroitin sulfate: add protease to the raw material for enzymolysis in water, adjust the pH, heat to inactivate the enzyme, and filter to obtain the enzymatic solution I; the enzymatic solution I is over-retained A membrane with a molecular weight of 10kDa is subjected to ultrafiltration to obtain concentrated solution I and effluent I; the concentrated solution I is separated and purified to prepare chondroitin sulfate; the effluent I is concentrated through a nanofiltration membrane to obtain concentrated solution II; the concentrated solution II is prepared with a strong anion resin Adsorption; add protease to enzymatic hydrolysis after resin filtration, heat to inactivate the enzyme, and filter to obtain enzymatic hydrolysis solution II; add activated carbon to the enzymatic hydrolysis solution II to adjust pH, then filter to obtain filtrate; sterilize, filter, and dry the filtrate to obtain collagen protein peptides. The preparation process of the invention is simple and easy to operate. The invention prepares the collagen peptide from the ultrafiltration waste liquid prepared from the chondroitin sulfate, which not only reduces the sewage discharge pressure, but also can turn waste into wealth, and can improve the comprehensive benefits of enterprises. |
