Variation of filter media type and thickness combination for coconut oil filtration

Abstract

Abstract Coconut oil is one type of oil that is widely used as cooking oil in Indonesia. There is a lot of oil sold that has not undergone purification, so it still contains a small amount of non-oil components, such as phosphatide sterol (0.06-0.08%), tocopherol (0.003%) and free fatty acids (<5%). This study aimed to find the most effective filter with a combination of the type and thickness of filter media to enhance the quality of coconut oil. The research method was to determine the combination of filter media thickness in the filtration column (fine sand, coarse sand, and zeolite). The results obtained showed that the best combination of filter media thickness namely filter 3 with a combination of column I (3 cm fine sand); column II (3 cm fine sand + zeolite 12.5 cm); column III (3 cm fine sand + zeolite 12.5 cm); column IV (3 cm fine sand) which produces oil with a clarity level of 99.35% T, moisture content of 0.014%, and free fatty acid 0.005%.
