A method for obtaining microcapsules of oil droplets by the formation
of an insoluble complex of protein-surfactant is described. The gelati
n 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 co
mplex is formed, was determined. These specific ratios also led to the
formation of microcapsules, in which the wall encapsulating the oil d
roplets, is composed of the insoluble gelatin SDS complex.
