Deacidification is an essential process to reduce free fatty acids (FFA) to an acceptable level for edible oils before entering the market. In this study, we investigated the feasibility of using ethanolamine as substrate to reduce acidity of high-acid rice bran oil (HRBO). The preliminary study showed that the best catalyst for the amidation was calcium oxide. Afterwards, optimization of reaction conditions was conducted. Under the optimized conditions, the deacidified RBO contained 1.1% FFA. Results also demonstrated that value-added products fatty ethanolamides were formed in the amidation reaction, which may greatly reduce the costs for deacidification process. This study indicated that the novel pretreatment method using calcium oxide as catalyst to reduce FFA is effective, economical and environmentally friendly.
