【Abstract】 The mutagenicity of products from heated edible oil, rape-seed oil, refined rape-seedoil, soybean oil, peanut oil and lard, had been assayed with Ames test. The extracts ofcondensed volatiles of rapeseed oil, refined rapeseed oil, soybean oil heated at about 270℃were positive in tester strain TA98 which had been activated with S9, but negative withoutS9; that from peanut oil and lard could not increase the revertants of TA98 or TA100. Themutagenicity of extract from rapeseed oil volatilese was stronger than that from soybeanoil. All of these edible oil itself, heated or unheated, were negative neither in TA98 orTA100. The results provide an experimental clue for studying the possible relationshipbetween high proportion of lung adenocarcinoma in Chinese women and the habit ofChinese cooking-fry and stir at high temperature.更多还原
