    Abstract: The present invention relates to a method of producing an encapsulated oil-solubleactive ingredient dissolved in oil. The method comprises mixing an oil-soluble activeingredient dissolved in oil with a solution of OSA-modified starch and a pectin stocksolution under high shear condition to form an oil-in-water emulsion and graduallyforming a suspension of microcapsules, wherein each of the microcapsules comprisesa microcapsule wall formed from the OSA-modified starch from the solution of OSA-modified starch; and adding a solution containing a cross-linker into the suspension ofmicrocapsules to cause a cross-linking reaction so as to form a cross-linked wall oneach of the microcapsules, wherein each of the microcapsules comprises the oil-solubleactive ingredient dissolved in oil, encapsulated within the cross-linked wall consisting ofOSA-modified starch cross-linked with pectin, and wherein the microcapsules aredispersible in aqueous media. The invention further relates to an encapsulated productobtainable by the method of the present invention. The encapsulated product is free ofadditional surfactant.
