A method for obtaining microcapsules of oil droplets by the formation of an insoluble complex of protein-surfactant is described. The gelatin type A studied, which is positively charged at the pH range studied, may form insoluble and soluble complexes with sodium dodecyl sulphate (SDS), an anionic surfactant. The binding isotherms were studied and the specific molar ratios of SDS to gelatin, in which the insoluble complex is formed, was determined. These specific ratios also led to the formation of microcapsules, in which the wall encapsulating the oil droplets, is composed of the insoluble gelatin SDS complex.
