Abstract
Most of the used cooking oil from households and catering premises in Malaysia will
eventually ends up in wastewaters. It will be discharged to the surface of waters because no alternative
steps were taken to overcome the waste from used cooking oil. As a component of wastewater, oil
is classified together with fats and waxes as grease. This trend results in the generation of a vast
waste stream that needs to be properly managed to avoid environmental damage. Thus, the
information regarding on the waste cooking oil properties is needed to contribute knowledge for
future research where the waste may reformed to value added product. Preliminary analysis of
used cooking oil properties via GCMS using capillary column shows n-Hexadecanoic acid and
Oleic acid as the major compounds present in the used frying oil. The analysis for determination of
volatile and moisture content with 3 replicates show an average of 0.02% moisture and volatile
content, which the experimental procedure was based on MPOB Test Methods.
