Cocoa butter, also called theobroma oil, is a pale-yellow, edible fat extracted from the cocoa bean. It is used to make chocolate, as well as some ointments, toiletries, and pharmaceuticals. Cocoa butter has a cocoa flavor and aroma. Its melting point is slightly below human body temperature. Extraction and composition Cocoa butter is obtained from whole cocoa beans. For use in chocolate manufacture, the beans are fermented before being dried. The beans are then roasted and separated from their hulls to produce cocoa nibs. About 54–58% of the cocoa nibs is cocoa butter. The cocoa nibs are ground to form cocoa mass, which is liquid at temperatures above the melting point of cocoa butter and is known as cocoa liquor or chocolate liquor. Chocolate liquor is pressed to separate the cocoa butter from the non-fat cocoa solids. Cocoa butter is sometimes deodorized to remove strong or undesirable tastes. Cocoa butter contains a high proportion of saturated fats as well as monounsaturated oleic acid, which typically occurs in each triglyceride. The predominant triglycerides are POS, SOS, POP, where P = palmitic, O = oleic, and S = stearic acid residues. Cocoa butter, unlike non-fat cocoa solids, contains only traces of caffeine and theobromine. Adulterants Some food manufacturers substitute less expensive materials in place of cocoa butter. Several analytical methods exist for testing for diluted cocoa butter. Adulterated cocoa butter is indicated by its lighter color and its diminished fluorescence upon ultraviolet illumination. Unlike cocoa butter, adulterated fat tends to smear and have a higher non-saponifiable content. Substitutes Cocoa butter is becoming increasingly costly. Substitutes have been designed to use as alternatives. In the United States, 100% cocoa butter must be used for the product to be called chocolate. The EU requires that alternative fats not exceed 5% of the total fat content. Substitutes include: coconut, palm, soybean, rapeseed, cottonseed and illipe oils; and shea butter, mango kernel fat and a mixture of mango kernel fat and palm oil, and PGPR. Uses Cocoa butter is a major ingredient in practically all types of chocolates (white chocolate, milk chocolate, and dark chocolate). This application continues to dominate consumption of cocoa butter. Pharmaceutical companies use cocoa butter's physical properties extensively. As a nontoxic solid at room temperature that melts at body temperature, it is considered an ideal base for medicinal suppositories. Personal care For a fat melting around body temperature, cocoa has good stability.
