Drum drying these jet-cooked dispersions yields dry products that can be easily redispersed in water and that are not oily to the touch. .Despite the absence of emulsifiers in these systems, aqueous dispersions are stable and can be stored for weeks without phase separation. The oil component is uniformly dispersed within the starch or starch-water matrix in the form of micron-sized droplets. A significant percentage of the oil is tightly bound within the starch matrix and cannot be easily removed by hexane extraction. Applications of these composites as adhesives, seed coatings, cosmetics, and fat-replacers in low-fat food products are being explored. |
