METHOD FOR FRACTIONALLY EXTRACTING MUCIN AND COLLAGEN

摘要

Provided is a method for fractionally extracting mucin and collagen from a jellyfish as a single raw material, including: (A) a protein-separating process including breaking a jellyfish to provide broken pieces containing water; subjecting the pieces to first solid-liquid separation to provide a liquid component; mixing the liquid component with a water-soluble alcohol having 1-4 carbons to prepare a first mixture wherein a concentration of the alcohol in the first mixture is at least 50 vol%; and subjecting the first mixture to second solid-liquid separation to provide solids, and (B) a fractionating process including mixing the solids with an aqueous solution of a water-soluble alcohol having 1-4 carbons wherein a concentration of the alcohol in the solution is from 10-40 mass%, to provide a second mixture; and subjecting the second mixture to third solid-liquid separation whereby the mixture is divided into a mucin-containing liquid constituent and a collagen-containing solid constituent.
