Preparation and Activation of Sarulla Natural Zeolites as an Adsorbent in Purification Process of Crude Palm Oil

The effect of Sarulla zeolite in Crude palm oil (CPO) purification was analyzed in zeolite weight and contact time variation on the influence of Free Fatty Acid, Saponification Value, Carotene, Vitamin-E, and Squalene content. This purification process induce increasing of saponification value from 272.41 mg KOH/g to 316.42 mg KOH/g at 20 g of zeolite and contact time for 30 minutes. On the other hand, this purification process reduced of Free Fatty Acid (FFA) content from 2.86% to 1.6% and vitamin E content from 907.79 ppm to 376.54 ppm after were adsorbed for 90 min with 30 g of zeolite used. Fatty acid composition analysis on CPO not significant changes in which is palmitic acid increased or decreased by about 1% under various conditions of zeolite use and contact time on the adsorption process. Sarulla natural zeolite can be used for CPO purification without affect theirs main content.
