ABSTRACT:
An improved method for the preparation of polyol fatty acid polyesters via a one step reaction. A polyol-type reagent is mixed with a fatty-acid containing reagent, and an esterification catalyst to form a reaction mixture. The polyol-type reagents include polyols and saccharides having hydroxyl groups, partially-esterified polyols and saccharides having both hydroxyl groups and lower alkyl ester groups, and fully-esterified polyols and saccharides having lower alkyl ester groups. The reaction is heated to about 95.degree. to 200.degree. C. for a time sufficient for the formation of saccharide fatty acid polyester while a non-fatty acid-containing lower alkyl ester by-product or an alcohol by-product are removed from the reaction mixture by a thin film reaction techniques. The use of thin film reaction methodology provides more efficient removal of by-products and greater yields of the polyol fatty acid polyesters. The polyol fatty acid polyesters, especially sucrose fatty acid polyesters, are useful as fat substitutes or low-calorie fats in food compositions.
