production 16.73 mqo2/kg oil), significantly higher than
the control sample containing peroxide (11.41 mqo2/kg
oil), respectively. After a month of preparation of
samples, peroxide fig leaf extract significantly reduced at
the same time. The highest peroxide value during
maintenance of control in the third month and the lowest
peroxide value of the samples in the fifth month was a fig
leaf extract (Fig. 2). At time zero (immediately after
heating) heating the catalyst oxidation reaction is
accelerated. As is clear separation of hydrogen bound to a
carbon adjacent to the carbon with double bonds needs
less energy. The reason is that hydrogen under resonance
or flipping the double bond electrons is for this reason
this hydrogen than other hydrogen the situation is volatile.
In the case of oleic acid, hydrogen is separated from the
carbon number 8 or 11 in each case leads to the formation
the two free radicals in the resonant (or actually four free
radicals) occurs. These radicals then combine with
oxygen, are converted to hydro peroxides. During the
formation of hydroperoxides, large amounts of Cis bonds
to during transport are becoming to Trans form the
amount of depends on the temperature. The increase in
temperature increases the rate of formation of hydro
peroxides formed in Trans [10]. Low-temperature
oxidation of fatty acids hydro peroxides produce more
relevant responses in the case of unsaturated compounds
are not reduced, but the high-temperature oxidation of the
double bonds are saturated so the stability of oil against
oxidation at high temperatures is important [13]. As a
direct correlation between the number of peroxide and
temperature, at zero time then there is production and the
increase peroxide value at zero time thermal treatment
compared to control for this reason. Peroxide thermal
treatments after five months there was a significant
difference compared to control and peroxide less shows
(Fig. 2). The reason could be because of the heat of
formation of polar compounds consists mainly of
oxidized triglycerides and polymerization triglycerides
increased. Yoshida et al., (2010) reports were consistent
with the results obtained in this study, that a significant
difference in peroxide fig leaf extract oil sample over
time [14].
