ABSTRACT

A method using supercritical carbon dioxide to produce concentrated carotenoids and tocols from palm oil is described. The free fatty acids of crude palm oil were esterified by acid-catalysis followed by transesterification of the triglycerides into methyl esters. Methyl esters are considerably more soluble in supercritical carbon dioxide than the triglycerides and free fatty acids, and are preferentially dissolved leaving a solution of highly concentrated carotenoids (20.11 wt%) and tocols (10.66 wt%).

PREPARATION OF A LOW VISCOSITY AND LIGHT COLOURED FATTY ACID-BASED POLYOLS

Chemical synthesis of a low viscosity and light coloured fatty acid-based polyol was conducted via a threestep reaction. The reaction variables, namely, temperature, pressure, amount of catalyst used, molar ratio of reactants and reaction time were investigated for their effects on the properties of the final polyol produced. Temperature and reduced pressure were found to […]

GAMMA TOCOTRIENOL AND PROSTATE CANCER: THE REGULATION OF TWO INDEPENDENT PATHWAYS TO POTENTIATE CELL GROWTH INHIBITION AND APOPTOSIS

Dietary vitamin E, highly expressed in palm oil, exists as either tocopherols or tocotrienols. Evidence indicates that vitamin Es may be potent cancer preventive agents. In this study, the γ- and δ- isoforms of vitamin E were found to be the most effective at cancer cell growth inhibition, with the tocotrienols being more effective than […]
