Determination of zeolite absorption effectiveness in different activation temperature in the coconut oil refining

Abstract

Abstract Coconut is one of the popular tropic and subtropical tree, especially in Asia. Some of the coconut oil produced in Indonesia is still a crude oil processed with heating that strongly lowering the quality of the oil. The general objective of this research is to increase the clarity of oil in the filtration process that thus improve the quality of coconut oil. The specific purpose of this study was to obtain the most effective heating temperature in the activation zeolite to be applied in coconut oil purification. The method used for refining is degumming followed with filtration with zeolite activated in different temperature. Observation parameters in this study were clarity level, water content, free fatty acids, and yield. From the result, we conclude that the most effective temperature for zeolite activation is 100°C resulted in coconut oil with a clarity level of 99.35T, the water level of 0.014, FFA of 0.005, and yield of 81.62%.
