  • Patent number: 4205006
    Abstract: Beef tallow is partitioned into five well defined fractions, each having its own distinctive fatty acid and glyceride composition and its own distinctive thermal characteristics, by a precise multi-step crystallization. Two of the five fractions are crystalline, one is a plastic solid and two are liquid. One of the liquid fractions accounts for 60% of the tallow and has a variety of uses in the formulation of salad oils, margarines and liquid and plastic shortenings. The composition and properties of the plastic solid fraction are very similar to those of cocoa butter and when it is mixed with cocoa butter it does not produce any significant change in thermal characteristics. In fact, an increment of one of the crystalline fractions or of one of the liquid fractions can be blended with an increment of the solid plastic fraction to make products that are compatible with cocoa butter and that have desirable thermal characteristics.
