Crop description. Allanblackia stuhlmannii and A floribunda—commonly known as allanblackia, mkanyi fat, bouandjo, and kagne butter (see Fig. 4.19)—belong to the family Guttiferae and grow in tropical areas, mainly in East Africa, Congo, and Cameroons. A high content of hard white fat (60-80%) can be extracted from the seed kernels of the trees. Allanblackia fats consist almost entirely of stearic acid (52-58%), oleic acid (39-45%), and palmitic acid (2-3%) [87]. Allanblackia has received considerable attention, based on its fat composition rather than its com­mercial importance [77].

Main uses. The use of the fat in soap manufacture has been suggested [176]. The timber is suitable for use under damp conditions. The pounded bark is used for medicinal purposes [177]. No references about its use as a biodiesel source have been found so far.
