Total carbonyl compounds in oils extracted from roasted and dried foods were estimated by the tentative method using 1-butanol instead of benzene as a solvent. Oils extracted from dried foods had generally showed higher carbonyl value (CV) than those from roasted foods. The CV estimated by the tentative method had a good correlation with that by the conventional method in oils extracted from roasted and dried foods, although the former did not always correlate with the latter for roasted and dried foods. It was expected that the tentative method using 1-butanol could be substituted for that using benzene and be useful for evaluating the quality of oils in roasted and dried foods.
