Abstract

Procedure for encapsulating water immiscible materials by a complex coacervation method using gelatin and gum arabic as essential components, characterized by the improvement that comprises the phase of adding an amount of a (100 - x), with a range of 0.065 to 5 parts by weight of a synthetic polymer, having an electric charge opposite to that of said gelatin and having a cloud point at a pH of 6.0 or less, as a third essential component to form a wall film, at 100 parts by weight of said gelatin and x parts by weight of said gum arabic, where x is 0 <= x <= 60.
