ABSTRACT

High-oil fractions were isolated from a series of starch-oil composites prepared by jet-cooking mixtures of starch and vegetable oil in water. They consisted of an emulsion of starch, oil, and water. These fractions were miscible in water and nearly immiscible in hexane. Emulsions from composites prepared with 10–40% oil contained 40–75% of the oil found in the original composite. Oil content of the emulsions varied with the oil content of the original composite, but the ratio of water to starch was essentially constant.
