Abstract
Reduced calorie food compositions are prepared using fatty acid esterified alkoxylated polyol fat substitutes derived from C.sub.3 and higher epoxides and having a high proportion of primary ester linkages. The fat substitutes may be obtained by alkoxylation of a polyol such as glycerin with the epoxide in the presence of a cationic/ring-opening polymerization catalyst, followed by esterification with a fatty acid or a fatty acid equivalent.
Claims6
A process of producing an esterified alkoxylated polyol useful as a reduced calorie fat substitute wherein at least 40% of the ester linkages therein are primary ester linkages, said process comprising
- (a) reacting a C.sub.3 -C.sub.10 1,2-alkylene oxide with a polyol in the presence of an effective amount of a cationic ring-opening polymerization catalyst to form an alkoxylated polyol intermediate wherein at least 40% of the hydroxyl end-groups of said alkoxylated polyol intermediate are primary hydroxy end-groups;
- and
- (b) reacting the alkoxylated polyol intermediate with a fatty acid entity selected from a group consisting of fatty acids, fatty acid anhydrides, fatty acid halides, and alkyl esters of fatty acids to form the esterified alkoxylated polyol.
