Macromolecular collagen

Description

Macromolecular collagenis made from fresh fish wastes like fish bone, fish skin and scale with a series of scientific manufacturing process. Firstly, fish bone, fish skin and scale were separated and collected after pretreatment, proceed to alkali treatment, acid treatment，double-enzyme composite hydrolysis and column separation. Membrane with designated aperture was used for the condensation of this product. After concentrating, theMacromolecularcollagen was spray-dried and the high purityMacromolecular collagen was produced. The protein assay of this product is more than *5%, and the molecular weight is more than ****0DA. It can be used in cosmetic and Biomedical engineering materials production.
