Crude palm oil is one of the richest plant source of carotenoids in terms of retinol (pro-vitamin A) equivalents. Carotenoids are naturally occurring C-40 plant pigments. Their conjugated polyenic chromophore is responsible for the characteristic light absorbing properties. Hydrocarbon and oxygenated carotenoids are termed carotene and xanthophyll respectively. Carotene, in particular α-carotene and β-carotene have long been associated with pro-vitamin A activity. Other minor carotene such as γ-carotene and β-zeacarotene also possess vitamin A activity (Choo, 1995).
