The seeds contain a fat that is solid at ambient temperatures. The kernel, which makes up about 60% of the seed, contains about 72% fat. The fatty acid composition of the fat is approximately: stearic acid 45 - 58% and oleic acid 40 - 51%. Only traces of other fatty acids are present. Its composition and relatively high melting point (35°c) makes the fat a valuable raw material that can be used without transformation to improve the consistency of margarines, cocoa butter substitutes and similar products[
