5 REDUCED CALORIE FAT MIMETICS WITH AN AVERAGE NUMBER OF OXYALKYLENE GROUPS PER MOLECULE OF NO MORE THAN FIVE

摘要

PURPOSE: Provided are fat substitutes comprising esterified alkoxylated polyols, particularly esterified propoxylated glycerol, which is susceptible to hydrolysis during digestion thus being partially digestible. CONSTITUTION: Reduced calorie fat mimetics comprise fatty acid-esterified alkoxylated polyol compositions having an average number of oxyalkylene groups per molecule of no more than 5 and from 5% to 39% primary hydroxyl groups based on the total amount of hydroxyl groups on the molecule. These reduced calorie fat mimetics are prepared by alkoxylating a polyol such that the average number of oxyalkylene groups per molecule is no more than 5, and subsequently esterifying with fatty acids. The reduced calorie fat mimetics can be synthesized to mimic the properties of the natural fats which are replaced in numerous food products. The fat mimetics are partially digestible thus obviating undesirable gastrointestinal side effects.
