Abstract

Pretreatment processes specifically degumming and acid esterification of Morings oleifera oil was investigated in this study. The oil was first degummed under a range of reaction conditions(percent water: 5%, 10% and 15%, time; 30 minutes, 1 hour and 1.5 hours, constant agitation and temperature). The reaction conditions were correlated with phosphorus removal from the oil. Varying percent water and degumming time has no significant difference with each other on the amount of phosphatides removed based on statistical analysis Under experimental conditions, best reaction condition with respect to the removal of phosphorus was: percent water-15%: degumming time-1 hour. FFA was not significantly affected by degumming at 0.05 level of confidence while drying of the degummed oil increase the amount of FFA but only to a very small amount. The oil was then subjected to acid esterification also at a range of reaction condition (methanol to FFA ratio: 1,2.25, 3g/g, sulfuric acid to FFA: 0.03, 0.05, 0.07g/g,constant agitation and temperature). the reaction conditions were correlated to the FFA removal from the oil. The amount of FFA decreases methanol to FFA ratio is increased. ON the other hand, the amount of FFA at increasing acid to FFA ratio decrease up to a certain point. At a ratio beyond the best value, there;s an increase in the FFA of the oil under experimental conditions. Best reaction condition with respect to FFA removal was: methanol to FFA ratio-3g/g; sulfuric acid to FFA ratio-0.05g/g.
