Abstract
Abstract A stable rapeseed oil shortening based on a blend of separately hydrogenated hardstock and softstock. The hardstock has an iodine value within the range of 0 to 20, and the softstock has an iodine value of at least 85. Because the shortening is crystallized in the beta polymorphic phase, it is stable over a wide range of temperatures.

Independent Claim
22 words
The all-rapeseed oil shortening of claim 1 wherein the softstock component iodine value is within the range of from 85 to 105.
Claim 2
Dependent Claim
22 words
The all-rapeseed oil shortening of claim 2 wherein the softstock component iodine value is within the range of from 87 to 95.
Claim 3
Dependent Claim
22 words
The all-rapeseed oil shortening of claim 1 wherein the erucic acid content is from 24% to 28% by weight of the shortening.
Claim 4
Dependent Claim
23 words
The all-rapeseed oil shortening of claim 1 wherein the softstock component comprises from 84% to 88% by weight of the all-rapeseed oil shortening.
Claim 5
Dependent Claim
23 words
The all-rapeseed oil shortening of claim 1 wherein the hardstock component comprises from 12 percent to 16 percent by weight of the shortening.
Claim 6
Dependent Claim
60 words
The all-rapeseed oil shortening of claim 1 wherein the softstock component has an iodine value of from 87 to 95, and comprises from 84 percent to 88 percent by weight of said shortening, and wherein the hardstock component has an iodine value of from 1 to 5 and comprises from 12 percent to 16 percent by weight of said shortening.
Claim 7
Independent Claim
142 words
A method of forming an all-rapeseed oil plastic shortening which comprises blending at a temperature in excess of 150*F a mixture comprising from 10 percent to 20 percent by weight of an all-rapeseed hardstock component having an iodine value of from 0 to 20, and from 80 percent to 90 percent of said mixture comprising a soft-stock component having an iodine value of at least 85; chilling the blended mixture to a temperature of from 40*F to 59*F whereby the mixture is nucleated with minute fat crystals in the beta polymorphic crystalline phase; agitating the nucleated chilled mixture to induce further crystallization; and tempering the all-rapeseed shortening for from 12 to 168 hours at a temperature within the range of from 70*F to 90*F to form a desirable, uniform consistency, stable, all-rapeseed plastic shortening which is predominantly of the beta crystalline phase.
