| Abstract: |
A method for producing alkyl glycoside polyesters comprising admixing a lower acyl ester alkyl glycoside, a fatty acid lower alkyl ester, and an alkaline 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 fat substitute food compositions containing alkyl glycoside fatty acid polyesters are produced in accordance with this present invention. The alkyl moiety may be unsubstituted or substituted by from 1-3 free hydroxyl groups or fatty acid esterified hydroxyl groups.

The embodiments of the invention in which an exclusive property or privilege is claimed are defined as follows:
1. A process for producing an alkyl glycoside fatty acid polyester comprising the steps of:
- reacting a lower acylated reducing saccharide halogenated at the anomeric carbon with a monohydric, dihydric, trihydric or tetrahydric alcohol having at least one free hydroxyl group, the remaining hydroxyl groups being protected wkh hydroxyl protecting groups, thereby forming a lower acyl ester alkyl glycoside;
- removing any protecting groups on the alkyl moiety of the lower acyl ester alkyl glycoside;
- admixing the lower acyl ester alkyl glycoside, a fatty acid lower alkyl ester, and an alkali metal catalyst to form a reaction mixture;
- heating said reaction mixture to a reaction temperature in the range of from 100° to 125° C. and maintaining the reaction temperature for a period of from one to three hours;
- while maintaining the reaction temperature, drawing a vacuum of from about 0 to 10 torr over the reaction mixture to obtain a yield of at least 95% of an alkyl glycoside fatty acid polyester in the reaction mixture; and
- recovering an alkyl glycoside fatty acid polyester from the reaction mixture.
