Although been a rich material with nutraceutical components and considerable residual oil content (5 to 6 mass % on a dry weight basis), the palm pressed fiber recovered from pressed palm fruits is a residue normally burned for energy supply. The extraction of the residual oil with n-hexane allows to obtain an oil rich in nutraceutical components, including the ²-carotene. However, the replacement of hexane is desirable due to its high toxicity and flammability.The main aim of this research project is extract palm pressed fiber (PPF) oil rich in carotenoids using a solvent mixture containing hexane + short chain alcohol. The solvent mixture allows partial replacement of hexane and may provide a synergistic effect on the solubility of ²-carotene. In order to select an appropriate solvent mixture the calculation of the solubility parameters of ²-carotene and solvents (hexane and short chain alcohols such as ethanol, n-propanol and 2-propanol) will be carried out. Solubility data of ²-carotene at temperature range from 10 up to 50 ° C will be experimentally determined and these equilibrium data will be modeled using the theory of Scatchard-Hildebrand. Finally, the PPF oil will be extracted using the mixture of solvents and this oil will be analyzed with respect to their quality and nutraceutical component preservation.
