摘要

A process for obtaining purified and concentrated fish proteins by dissolving fish in liquid medium by alkaline hydrolysis, separating and eliminating lipids and other impurities and concentrating proteins by chemical and/or physical methods to be used as human food and/or animal, characterized in that the alkaline hydrolysis is carried out directly without previously parking the raw material in liquid medium; the alkaline hydrolysis is carried out in a total time of less than three hours; the resulting liquid mass contains in solution bound lipids in the form of lipoproteins which have not been destroyed by the brevity of alkaline hydrolysis and which are soluble in water at neutral pH and alkaline pH; the lipoproteins are precipitated by bringing the liquid mass to an acidic pH lower than pH 5.5 (five and a half); the lipoproteins precipitated in this pH range are eliminated by any suitable industrial process to separate and eliminate insoluble solids from a liquid mass; the liquid obtained, free of insoluble non-protein solids, free lipids and lipoproteins, which is at acidic pH, is brought back to alkaline pH and subjected to the action of oxidizing agents; the aqueous liquid thus obtained, brought to neutral pH constitutes a purified and deodorized solution of proteins that is concentrated.
