Abstract
Oil blending is an economical method to modify and improve the characteristics
of vegetable oil. This research was aimed to study the physicochemical quality of
palm-canola composite oil during the intermittent frying of soybean curd (deep
fat frying). Palm oil was blended with canola oil in different ratios (100:0, 90:10,
80:20, and 70:30). Two hours of frying was performed everyday for 4 consecutive
days. The result showed that palm-canola composite oil compared to control
(palm oil) alone increased the quality of frying oil by the decreased of viscosity,
yellowness index (YI), Totox value (TV), free fatty acid (FFA) value and the oil
absorption in soybean curd. However, the blends indicated unstable towards
oxidation reaction which can be seen from peroxide value (PV) and p-anisidine
value (p-AV). Different frying time significantly affected oil degradation and it
can be seen from all parameter, while oil absoption of fried soybean curd was not
significantly affected. Palm-canola composite oil with ratio 90:10 was the best
ratio which can lowered the rate of oil degradation. Therefore, this research
indicated that palm-canola composite oil can reduce the hydrolysis and
polymerization reaction of frying oil but not for oxidation reaction of palm frying
oil.
