Abstract: The research on the
effect of addition of kepayang seed (Pangium edule R.) hexane extract to the
peroxide number of traditionally-processed coconut oil (Cocos nucifera L.) has
been completed. The aim of this research is to know the effects concentration
of intentionally-added kepayang seed (Pangium edule R.) hexane extract into
coconut oil (Cocos nucifera L.) and storage duration to the peroxide number and
to discover the secondary metabolits contained in the kepayang seed (Pangium
edule R.) hexane extract. The concentration of kepayang seed (Pangium edule R.)
hexane extract added were 0, 75, 150, 225 and 300 ppm and the storage duration
were 0, 2, 4, 6 and 8 weeks. While the method used for phytochemical test was
color test. The peroxide number determination was conducted using iodometric
titration method and the data obtained was subsequently using two-way ANOVA
test. The result showed that there were the effects of kepayang seed (Pangium edule
R.) hexane extract concentration and storage duration to the peroxide number of
coconut oil (Cocos nucifera L.) at the alpha of 0.01 where at the interaction
bar the value of Fcalculation (51.76) > F table (2.81). While
from the phytochemistry using kepayang seed (Pangium edule R) hexane extract
the result were positive, for alkaloid, triterpenoid, saponin and flavanoid.
The lowest peroxide number on week 0 with 300 ppm kepayang seeds (Pangium edule
R.) extract was 0.0091 mg O2/g, while the highest one was obtained on week 8
with 0 ppm kepayang seed (Pangium edule R.) hexane extract, i.e. 0.0546 ppm mg
O2/g. From the result known, the peroxide number obtained had not exceeded the quality
standard established by SNI for coconut oil (Cocos nucifera L.) yet, i.e. 5 mg O2/g.
