Abstract

Mandar coconut oil made in Tulu village, Majene Regency, West of Sulawesi, is very popular among Sulawesi Barat people. It is because of the unique aroma which is not owned by other Mandar oil traders. In addition, according to Mandar coconut oil trader who is also the produsen of Mandar oil said that his coconut oil could be stored for months. This research aimed to know the influence of water content and free fatty acid content on Mandar coconut oil shelf life. Gravimetric Method and Alkaline method were used to determine the water content and the free fatty acid content respectively. The oil was stored at room temperature. Water content and free acid content were measured every week, i.e week zero to week four (5 observations). Shelf life estimation was done by applying the kinetic theory. The result shows that the water content and the free fatty acid content increase as shelf life increases. Mandar coconut oil can be stored at room temperature for 1 month, 12 days. Keywords: Mandar coconut oil, water content, free fatty acid, shelf life

Abstract

Mandar coconut oil is one of the coconut processed products, which has become superior product in West Sulawesi especially in Majene regency. Unfortunately, the Mandar coconut oil can’t be used more than a month because the water content and free fatty acid content of the oil have exceeded the maximum standard of SNI, so it can adversely affect on health. On the other hand, the existence of rice husk in Indonesia itself especially in West Sulawesi has not received attention and is limited to a few needs such as for ash or livestock feed, and the rest is thrown away. This research aims to determine the effect of rice husk ash addition on the increasing of Mandar coconut oil quality. Completely randomized design was used in this research with 6 rice husk ash concentration variation levels i.e. 0%, 5%, 10%, 15%, 20% and 25%. The result shows that the addition of rice husk ash with 10% to 25% can reduce the water content of the oil until the quality standard of SNI is full filled. The highest reduction of water content was reached with 25% of rice husk ash concentration with 81% of reduction percentage. While, the addition of rice husk ash with 15% concentration can reduce the free fatty acid content of Mandar coconut oil until 32%.
