Abstract

Nyamplung (Calophyllum inophyllum) oil is one of the promising raw materials because of its high oil content. Previous researches were limited to its characterization and conversion into biodiesel. In this work, triacylglycerols (TAG) was separated from the crude oil via batchwise solvent extraction. By using a mixture of petroleum ether-methanol (methanol 25%) and a solvent-to-oil mass ratio of 5, high recovery and purity of TAG were obtained. It was found that free fatty acids (FFA) content was decreased from 8.51 to 2.16% and 0.35% after one- and eight-stage extraction, respectively. Moreover, TAG content increased significantly from 78.30 to 91.46% and 98.53% after one- and eight-stage extraction, respectively. It was shown that the proposed method can replace degumming, neutralization, and bleaching steps in chemical refining process. Although the proposed method requires a large amount of organic solvents that are flammable and environmentally unfriendly, the solvents can be recovered easily.
