UNASSIGNED: Strong and stable antioxidation effects of @entity13768 ( @entity16549 ) are widely accepted and utilized in commercial frying oil; however, the mechanism is not fully established. On the other hand, canola oil contains about 700 ppm (mg/kg-oil) of the natural antioxidant, @entity4793 . Canola oil containing 0, 1 and 10 ppm added @entity16549 was heated at 180    for 1 h under stirring, then left for 2-3 days at room temperature; this treatment was repeated 5 times. Compared to pure canola oil, @entity16549 -containing canola oil exhibited remarkably lower @entity2625 , @entity30471 and acid values, a lower decrease in @entity4793 content but a higher @entity26 content during the heating experiments, implicating low @entity26 consumption for the oxidation. While @entity16549 has not been known to exhibit antioxidative effects at ambient temperatures, the present results show that @entity16549 prevents autoxidation as well as thermal oxidation. In addition, @entity16549 , not @entity4793 , provided the major antioxidative effect during intermittent heating, and the decrease of tocopherols was significantly inhibited by @entity16549 . Phase contrast microscopy confirmed that @entity16549 contained in canola oil was suspended as particles. Also, the @entity26 content in standing @entity16549 -containing canola oil decreased as the depth of oil increased, corresponding to the @entity16549 distribution, which also decreased as the depth of oil increased. Moreover, @entity16549 had a higher affinity for @entity26 than canola oil in a mixture of canola oil/ @entity16549 , 1:1 v/v. Thus, it is suggested that @entity16549 restricted the behavior of @entity26 dissolved in canola oil by attracting @entity26 in and around the @entity16549 particles, which is wholly different from the radical scavenging antioxidation of @entity4793 .
