FIELD: fish waste processing.
SUBSTANCE: following is described: a method of producing fish collagen homogenizate including cleaning cod skins, grinding, washing with water, after cleaning the fish skins, the collagen homogenizate is poured with 2–3% mineral acid HCl at a hydromodulus of 1–1.5, incubated for 30–40 minutes, then washed with tap water until the pH of the wash water is neutral and with distilled water.
EFFECT: production of a product with a calcium phosphate content of less than 2–3% on a dry basis.
