Abstract
Abstract Hardstock fat compositions of the present invention are comprise triacylglycerides containing one linoleic acid acyl group (C18:2) and two acyl groups independently selected from C18:0-C26:0 saturated fatty acyl groups. The hardstock fats are essentially free of cholesterolemic C12:0-C16:0 saturated fatty acids, yet retain all of the desirable characteristics which those cholesterolemic fatty acids impart. The hardstock fats are useful as components in comestible products, particularly in plastic shortenings.

Claim 1
Independent Claim
117 words
A plastic shortening composition comprising: (a) from about 65% to about 95% of a triglyceride fat or oil base stock having an iodine value of less than 150; and (b) from about 5% to about 35% of a beta prime tending hardstock with a melting point between 35° C. and 70° C., said hardstock consisting essentially of: (i) from about 14% to 100% of a triglyceride esterified with a C 18:2 fatty acid and the remaining fatty acids are selected from the group of C 18 -C 26 saturated fatty acids; and (ii) from about 86% to 0% of a mixture of triglycerides esterified with one or more saturated or unsaturated C 18 -C 26 fatty acids.
Claim 2
Dependent Claim

Claim 5
Dependent Claim
34 words
A shortening to claim 3 wherein said hardstock comprises a hardstock fat comprising at least about 14% of a triglyceride esterified with a C 18:2 fatty acid group and two C 22 fatty acids.
Claim 6
Dependent Claim
50 words
A shortening according to claim 3 further comprising from about 65% to about 95% of a base-stock selected from the group consisting of soybean, corn, sunflower, rapeseed, low erucic acid rapeseed, canola, peanut, coconut, palm kernel, palm, sardine oil, lard, tallow, cottonseed, olive, safflower, sesame, synthetic oils, and mixtures thereof.
Claim 7
Dependent Claim
