It has been reported that @entity13768 ( @entity16549 ) inhibits @entity26 dissolution into oil by forming a monolayer on the surface of the oil, thereby reducing thermal oxidation. In the present study, the distribution of @entity16549 was determined by the inductively coupled plasma atomic emission spectroscopy in standing @entity16549 -containing canola oil. @entity16549 did not disperse in the oil uniformly, but there was a tendency that the @entity16549 concentration decreased as the depth of oil increased, and the concentration of the bottom part was the lowest. When canola oil was covered with @entity16549 by dropping it gently on the surface of the oil and kept at 60  C, the @entity26 content and oxidation of the oil were lower than those of the control canola oil. @entity16549 -containing canola oil and canola oil were heated with stirring from room temperature to 180  C, and then allowed to stand while cooling. @entity26 contents of both oils increased up to 120  C then dropped abruptly. While cooling, @entity26 contents sharply increased at 100  C and approached the saturation content, although the increase for @entity16549 -containing canola oil was a little slow. Likewise, the thermal treatment of @entity16549 -containing canola oil and canola oil at 180  C for 1 h under stirring was repeated 5 times with standing intervals for 2-3 days at room temperature. Oxidation of the former was less than that of the latter in spite of its high @entity26 content. In conclusion, the @entity26 content of oil with/without @entity16549 addition increased, but oxidation of @entity16549 -containing canola oil was inhibited both during heating and standing with intermittent heating. It was suggested that @entity16549 exerted its antioxidative effect regardless of whether it covered the oil or was dispersed in it.

A study on the effect of @entity13768 from the viewpoint of XXXX content in oil.
