A beta stable plastic shortening exhibiting reduced levels of saturates and trans fatty acids and a unique process is disclosed. The shortening is particularly useful in confectionary, baking, and frying applications. The plastic shortening of the present invention contains from about 6% to about 25% by volume, of an inert gas and from about 75% to about 94% by volume of a fat made of a) from about 74% to about 90% by weight of a base oil having less than 10% by weight of trans fatty acids, b) from about 10% to about 20% by weight of a hardstock blend, having a beta stable crystalline phase consisting essentially of i) from about 20% to about 80% by weight, of a beta phase tending hardstock component having an iodine value of less than 10, and ii) from about 20% to about 80% by weight, of a beta prime phase tending hardstock component having an iodine value of less than about 10. If desired, the plastic shortening may also contain from about 25 ppm to about 500 ppm added antioxidant and/or from about 1% to about 8% of an emulsifier. From about 0.05% to about 3% additional ingredients may also be added to the plastic shortening. The plastic shortening of the present invention has a finished shortening penetration of from about 160 mm.backslash.10 to about 275 mm/10 and a maximum gas bubble size of less than 1 mm.

[ What is claimed is:] [1.] A process for making a low saturate, low trans beta stable plastic shortening comprising the steps of:1) fully melting and mixing at a temperature from about 120.degree. F. (49.degree. C.) to about 180.degree. F. (82.degree. C.) a mixture comprising:a) an edible oil having less than 8% by weight of saturated fatty acids, and from 0% to about 10% by weight, of edible trans fatty acids, wherein said edible oil comprises from about 74% to about 90% by weight of said plastic shortening;b) a hardstock blend having a beta stable crystalline phase consisting essentially of i) from about 25% to about 80% by weight, of a beta phase tending hardstock component having an iodine value of less than 10, and ii) from about 20% to about 75% by weight of a beta prime phase tending hardstock component, crystallized in beta form, having an iodine value of less than about 10, said hardstock blend comprising from about 10% to about 20% by weight of said plastic shortening;c) from 0 to about 500 per million by weight of an antioxidant, andd) an effective amount of an emulsifier;2) injecting from about 12% to about 23% of an inert gas, under a pressure of from about 50 to about 700 pounds per square inch to form a shortening mixture;3) rapidly cooling said shortening mixture in a scraped wall heat exchanger in less that about 60 seconds to a temperature of from about 40.degree. F. (4.4.degree. C.) to about 70.degree. F. (21.1.degree. C.) while maintaining a pressure of from about 50 to about 700 psig;4) agitating said shortening mixture and imparting enough work input in a picker box for from about 1 to about 8 minutes to transform said shortening mixture to at least 50% beta crystals upon filling, said shortening mixture having a finished shortening consistency of from about 160 mm/10 to about 275 mm/10 and a maximum inert gas bubble size less than 1 mm;5) heating said shortening to a temperature from about 70.degree. F. (21.degree. C.) maximum to 95.degree. F. (35.degree. C.) and passing said shortening through a slotted valve no more than 0.060 inch in width while lowering the pressure from 300 psig to about 700 psig to atmospheric pressure to form a fine inert gas bubble dispersion; said shortening mixture having a filling temperature of from about 40.degree. F. (4.degree. C.) to about 95.degree. F. (35.degree. C.);6) tempering said shortening at a temperature of from about 80.degree. F. (27.degree. C.) to about 110.degree. F. (43.degree. C.) for at least about 24 hours.
