Abstract
Novel ether bridged polyester compositions are disclosed. Two multibasic acids, e.g., citric acid and isomers thereof, are joined by an ether-like linkage. (The citric acid molecule provides an hydroxyl which may be used in the ether linkage.) The carboxyls of the multibasic acid moieties of the new compounds may then have long chain fatty alcohols esterified thereto to provide the subject ether bridged polyesters. The superficial appearance of the polyester portions of the novel compounds is that of a triglyceride; however, upon close examination of the ester linkage, it is apparent that the novel compounds are reverse esters when compared to true triglycerides. It has been determined that a minimum of three reverse ester alkyl chains must be present on the molecule in order to consider it as a fat mimetic. The utility of the disclosed compositions is as a low to non-caloric fat substitute in food products. Additionally, the ether bridged polyesters may be used as lubricants for machinery.
