Abstract

Procedure of encapsulation of hydrophobic material by complex coacervation using gelatin as an essential component, characterized in that it comprises the operation of encapsulating, using around 5 to 200 parts by weight of a copolymer of acrylic acid, methacrylic acid or one of its salts per 100 parts. of gelatin, said copolymer having an electric charge opposite to that of gelatin, as a pair of gelatin wall-forming material.
