It contains no trans fat, and its use in food has increased as food-labelling laws have changed to specify trans fat content. Oil from "Elaeis guineensis" is also used as biofuel.

Elaeis guineensis and forms of "Elaeis guineensis" have been selected that have different characteristics. These include: Before the Second World War, selection work had started in the "Deli dura" population in Malaya. Pollen was imported from Africa, and DxT and DxP crosses were made. Segregation of fruit forms in crosses made in the 1950s was often incorrect. In the absence of a good marker gene, there was no way of knowing whether control of pollination was adequate. After the work of Beirnaert and Vanderweyen (1941), it became feasible to monitor the efficacy of controlled pollination. From 1963 until the introduction of the
