Abstract

In rice bran, fat content estimated 15%, contains bioactive compounds, typically Oryzanol. The rice bran oil produced by chemical refinering. However, due to wax content in the bran, it can reached 30% w/w. Therefore, the refinering often using heavy chemicals, in long time and high temperatures. This makes lossing of Oryzanol content in oil, therefore bran oil has an Oryzanol content only about 5000 ppm. The research of rice bran oil extraction and chemical refining of crude oil to neutralization, removal wax from rice brand before oil extraction. The main purpose of researchs is to obtain neutral oil with stability chemical indicators while increasing Oryzanol content which is the main antioxidant characteristics of rice bran oil. The conclusions of rice bran oil neutralization IV is 92.6 g iodine/ 100g, PV is 22.9 meq/ kg, FFA is 24.4 % and Oryzanol concentrations are reached 12,763 ppm, while not detecting trans fat in rice bran oil neutralization.
Keywords: Rice bran, rice bran oil, rice bran oil extraction, Oryzanol, trans fat.
