摘要
Water in oil emulsions would be prepared by silicones (SO), modified silicones (DC8500) and a food grade stabilizer (starch 1). With increasing water contents, the emulsions turned from a liquid-like to gel-like behaviors with enhancing storage and loss modulus. When DC8500/SO was 1/17 with 10 wt% starch 1, a high internal phase emulsion can be obtained with 95 wt% water content. DC8500 and SO worked as efficient emulsifiers and possessed amphiphilic property to form emulsions with water in different ratios. A food-grade starch 1 was supplied as a stabilizer which can enhance both water content and strength of emulsion when added in a low concentration. Besides, it is indicated that the food grade starches provided potential benefit on stabilizing emulsions in very low concentration. (C) 2018 Elsevier Inc. All rights reserved.
