In the previous paper*, the authors observed that the presence of toxic substance in thermally oxidized oils. We have wondered the presence of this toxic compound in used commercial frying oils. Therefore, we checked the amount of toxic compound in used frying oils which were collected from manufacturers. Most of the samples used for frying (soybean oil used for vegetables and shrimps, rice oil for dough-cakes, lard for instant-cook Chinese noodle and pork cutlets) contained trace amount of toxic compounds, however, rape-seed oil used for beancurds and soybean oil used for fish ball contained fairly high amounts of toxic dieter (1.5 and 0.6%, respectively). The results of feeding experiments of those oils indicated that the weight gain of rats decreased with increase of the toxic compounds in oils. (* Yukagaku, 21, 13 (1973))
