Crude palm oil is the richest natural plant source of carotenoids in terms of retinol (provitamin A) equivalent. This article reports on
the carotenoids found in palm oil, its fractions, byproducts, and derivatives from the Elaeis guineensis and E. oleifera palms, including their hybrids and a back-cross, as well as the carotenoids of pressed palm fibres, second-pressed oil, palm leaves, and palm-derived alkyl esters;
two novel procedures for preparing highly concentrated sources of carotenoids (>80,000 ppm), by recovery by palm alkyl esters, and by retention and concentration in deacidified and deodorized red palm oil;
the carotenoid content and profiles of the above sources obtained by high-performance liquid chromatography; and
nutritional effects of palm oil carotenoids and their potential applications for health promotion and disease prevention.
