Embodiment 1

[0031] A preparation method of shark chondroitin sulfate chelated zinc salt, comprising the following steps:

[0032] 1. Shark cartilage removes fat, shark meat, and calcified bones, and grinds it with a pulverizer to obtain 1kg of shark cartilage powder.

[0033] 2. Put the above-mentioned shark cartilage powder in a reaction kettle, add 10kg of water, add 5g of animal protease, use sodium hydroxide and sulfuric acid to adjust the pH value, and control the pH value of the reaction system to 6.5, and the enzymatic hydrolysis temperature is 65°C. The solution time is 6h. After the enzymatic hydrolysis reaction, use a centrifuge with a rotating speed of 8000rpm to remove solid impurities, and use a nanofiltration membrane with a molecular weight cut-off of 5kD to remove impurity proteins from the obtained clear liquid to obtain a shark chondroitin sulfate solution.

[0034] 3. Put the above-mentioned shark chondroitin sulfate solution in an ultrasonic reaction tank, add zinc su...

Abstract

The invention relates to a preparation method of shark chondroitin sulfate chelated zinc salt. The method comprises the following steps: pretreating shark cartilage to obtain shark cartilage powder, and preparing shark chondroitin sulfate by utilizing an enzyme extraction and centrifugal machine separating synergistic nanofiltrating membrane purification linkage technology. The shark chondroitin sulfate zinc salt crude product is prepared by taking the shark chondroitin sulfate as a raw material and utilizing an ultrasonic cavitation and shark chondroitin sulfate zinc chelation technology. And a shark chondroitin sulfate zinc salt powder finished product is prepared by utilizing a centrifugal separating electrodialysis purification and spray drying integrated technology. The method is mild in reaction condition, controllable in quality and suitable for large-scale production. The shark chondroitin sulfate zinc salt prepared by the preparation method disclosed by the invention is concentrated in average relative molecular mass, good in solubility, high in bioavailability, high in safety and free from toxic and side effects, and can be applied to the fields of antiinflammatory health foods and medicines.

Description

technical field [0001] The invention relates to the field of deep processing of aquatic products and belongs to the field of biotechnology, in particular to a preparation method and application of shark chondroitin sulfate chelated zinc salt. Background technique [0002] Chondroitin Sulfate (CS) is an acidic polymeric viscous polysaccharide from animal cartilage tissue. The sugar chain of CS is composed of alternating glucuronic acid and N-acetylgalactosamine disaccharide units. Its biological structure determines its It has the biological activity of regulating bone and joint function. In European and American countries, CS and its derivatives are widely used in the prevention and treatment of arthritis. In my country, in 2010, the Pharmacopoeia of the People's Republic of China listed CS as a routine drug for the prevention and treatment of joint diseases. my country is the largest country in CS production. There are about 200 domestic manufacturers, and the output acco...
