Abstract—Free fatty acid (FFA) in crude palm oil (CPO) is varies depending on harvesting methods, storage conditions up to processing at oil mill. CPO with low FFA is contemplated as superior. Lowering the FFA level in high FFA CPO by lipase Candida Antartica enzyme in passed research by others is achievable. Enzyme is applied in standard CPO to investigate if further FFA reduction is able to take place and produce premium CPO (<1% FFA). There are four different lipase Candida Antartica brands used in this study. Samples submitted for enzymatic remediation using rotary evaporator under 100mbar vacuum with rotation at 260rpm. FFA less than 1% was achieved after 24 hours reaction by all 4 brands. The FFA reduction was intensified with the presence of glycerol that provides more sites for fatty acid attachment. At 2% glycerol, 71-88% FFA was reduced whereas at 1% glycerol, 46-75% FFA was reduced. However, partial glycerides was increased with the presence of glycerol. This study concluded that enzymatic remediation could further reduce FFA in CPO in order to obtain premium CPO (<1% FFA).

Index Terms—crude palm oil, enzyme, free fatty acid, glycerol
