The invention provides a
chondroitin sulfate production process. A
raw material is crushed to form particles with a
diameter of 3-5mm, the particles are placed into an immersion
pool, water which is 7-8 times as heavy as the
raw material is added into the immersion
pool for immersion, the particles are sent into a pulping
machine to form a
raw material pulp, the raw material pulp is sent into a reaction kettle, is heated and boils, then heat preservation is carried out for 10-15 minutes, and floating oil is taken out after temperature reduction to obtain collagen
thermal denaturation liquid; a PH value of
thermal denaturation liquid caustic soda is adjusted,
bacterial enzymes are added, heat-preservation enzymolysis is carried out for 5-6 hours, the temperature is reduced to be the same as the temperature of cold water, then the temperature is raised to 70-75 DEG C, and heat-preservation is carried out for 10-15 minutes; materials after enzymolysis are clarified and filtered, and a wet-state
chondroitin course product is obtained after
alcohol precipitation,
dehydration and
alcohol removal; decoloration, concentration,
alcohol precipitation and alcohol removal are carried out on the wet-state
chondroitin course product, and a chondroitin fine product is obtained after
drying. Mechanical physical degradation is carried out, the chondroitin is prevented from being degraded under a high temperature, the
yield rate is improved, production cost is reduced, the yield is improved, the production efficiency is improved, the production is increased and the process is scientific and
environmentally friendly.
