Effect of stored oil palm trunk sap towards methyl ester synthesis / Nurnuha Shamsir... [et al.]

Oil palm trunk (OPT) has highest content of sap, 80% of the overall weight. OPT sap contains free sugars which can be converted into valuable compounds such as ester. The objective of this study is to determine the changes of free sugars at different storage time and the effect on methyl ester synth...
