Linked esterified alkoxylated polyols useful as reduced calorie fat substitutes

摘要

Reduced calorie food compositions are prepared using linked esterified alkoxylated polyol fat substitutes comprised of polyether glycol linking segments, polyol segments, and fatty substituents (which may be fatty acid ester and/or fatty acid-esterified oxyalkylene segments). The fat substitutes are obtainable by alkoxylating a polyol such as glycerin with a monoepoxide such as propylene oxide and a polyepoxide-functionalized polyether glycol (either simultaneously or sequentially) and esterifying the resulting alkoxylated polyol with a fatty acid or its equivalent. Alternatively, the polyepoxide-functionalized polyether glycol could be condensed with a fatty acid partial ester of a polyol or an alkoxylated fatty acid partial ester of a polyol.
