Background of the study
Andiroba is a tall rainforest tree that grows up to 40m high. It is in the same family as mahogany, and it has been called Brazilian mahogany or bastard mahogany due to their similarity. It can be found growing wild throughout the Amazon rainforest, usually on rich soils, in swamps, and in the alluvial flats marshes and uplands of the Amazon basin. It can also bhe found wild or under cultivation in Brazil in the island regions, Tocantins, Rio Solimoes, and near the seaside. It is one of the large-leafed trees of the rainforest and can be identified by its large and distinctively textured leaves. Andiroba wood is soft, yet durable, and much sought by sawmills. It has in the past been shipped to the United States for use in the furniture industry and for the other uses. Its durability and impalatability to insects have guaranteed commercial demand for the wood, and as a result, the species has been devastated in all areas near major towns in Amazonia. It could, however, be cultivated easily in the Amazon or other regions of Brazil. The andiroba tree produces a brown, woody, four-cornered nut, some 3-4 inches across that resembles a chestnut. The nut contains several oil-rich kernels or seeds that average about 63% oil, which is pale yellow in color. Andiroba oil is a sustainable rainforest product that has a long history of use in South America as well as commercial value. A single tree will produce, on average, about 200 kg of nuts annually. Approximately 6 kg of
