Abstract
Abstract An unsaturated or low saturated frying oil which imparts the beefy or tallow flavor to foods that is characteristic of animal fats is disclosed. This oil is made by a process of esterifying glycerine with the unsaturated fraction of animal fat and then deodorizing or refining the resultant triglyceride. The unsaturated fraction of the animal fat contains minor fatty acids which produce this flavor on heating. Usually less than 5 mg of cholesterol/100 gm is in the oil.

Claim 1
Independent Claim
118 words
A process for making a frying oil comprising: a) fractionating fatty acids from animal fats to make an unsaturated fraction and a saturated fraction; wherein said unsaturated fraction comprises from 50% to 85% oleic acid, less than 15% saturated fatty acids, from 5% to 25% minor fatty acids and less than 10 mg/100 gm of cholesterol; b) esterifying glycerine with said unsaturated fraction at a temperature of from about 100° C. to 250° C. while concurrently removing water from the reaction, the ratio of unsaturated fatty acid to glycerine being from 3:1 to 8:1; and c) deodorizing the resultant low saturated triglyceride by steam stripping at temperatures of from about 220° C. to about 270° C. under vacuum.
Claim 2
Dependent Claim
