    Bottle choice tests in rats are useful for the study of fat appetite. However, little is known about the feeding behavior of rats toward oxidized oil. In this study, 24-h two-bottle choice tests were performed in male Sprague-Dawley (SD) rats for 5 days. When rats were given a choice between thermally oxidized oil and fresh oil, they ingested more fresh oil. A choice test between vapor-added fresh oil and fresh oil showed that rancid flavor is involved in the avoidance of oxidized oil. Results with deodorized oxidized oil indicated that a nonvolatile product also influenced choice. In conclusion, rats could distinguish oxidized oil from fresh oil and preferred fresh oil.
