ALKYL GLYCOSIDE FATTY ACID POLYESTER FAT SUBSTITUTES AND PROCESS FOR PRODUCING LOW CALORIE FOODS THEREFROM

摘要

A method for producing alkyl glycoside fatty acid polyesters comprising admixing a lower acyl ester alkyl glycoside, a fatty acid lower alkyl ester, and an alkali metal catalyst to form a reaction mixture. Thereafter, the reaction mixture is heated to a reaction temperature and maintained at that temperature for a predetermined period of time. A low vacuum is drawn over the mixture. Yields of on the order of 95 % to 99 % can be achieved in accordance with this method. Novel low calorie food compositions containing the alkyl glycoside fatty acid polyesters are described. The low calorie foods are produced by substituting for the triglyceride fats normally found in foods or food products, a fat substitute comprising an alkyl glycoside fatty acid polyester, the polyester having at least 4 fatty acid ester groups, wherein each fatty acid has from 4 to 24 carbon atoms, and wherein the alkyl glycoside moiety comprises a saccharide portion and an alkyl portion, the alkyl portion having from 1 to 24 carbon atoms.
