Abstract

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.
