USE OF UNPIGMENTED FISH SKIN, PARTICULARLY FROM FLAT FISH, AS A NOVEL INDUSTRIAL SOURCE OF COLLAGEN, EXTRACTION METHOD, AND COLLAGEN AND BIOMATERIAL THEREBY OBTAINED

摘要

The invention relates to the use of non-pigmented skin of flatfish as new industrial source of collagen. As unpigmented skin, in particular using the ventral skin, preferably from sole, dab, turbot, flounder. advantageously extracted from the acid-soluble collagen in its native state, which is separated by precipitation from the supernatant. The invention improves the efficiency of production of collagen with a lower cost while retaining the native properties of the protein, and reproducibly.
