low molecular weight chondroitin sulfates from cartilage of chondrichthyes and Process for preparing thereof

摘要

The present invention relates to low-molecular chondroitin sulfate obtained from cartilage of cartilage fish and a method for producing the same. More specifically, low-molecular chondroitin sulfate (CS) obtainable through economical and effective processes from cartilage of cartilage sharks and skates And it relates to a manufacturing method thereof.;The present invention can be obtained from cartilage of cartilage fish, and an object of the present invention is to provide chondroitin sulfate having a low molecular weight, more preferably an average molecular weight of 3,000 to 12,000 Da.;An object of the present invention is to provide a method for producing low molecular weight chondroitin sulfate through enzymatic hydrolysis, acid hydrolysis, filtration and purification from cartilage of cartilage fish.;The present invention in the production of chondroitin sulfate using cartilage of cartilage fish as a material,;Grinding the cartilage of the cartilage fish,;Enzymatic hydrolysis of cartilage by adding water and enzyme to the ground cartilage,;Acid hydrolysis by adding weak acid to cartilage enzyme hydrolyzate,;Filtering and purifying the acid hydrolyzate.
