摘要
本文采用微核试验方法，对煎炸油的遗传毒性进行了研究。结果表明：煎炸油能引起小鼠骨髓嗜多染红细胞（ＰＣＥ）微核率增高，并且随着煎炸时间延长，微核率有增高的趋势，而新鲜未加热菜油不能使小鼠ＰＣＥ微核率增加。本研究提示煎炸使油脂发生热变质，产生一些能使细胞染色体损伤的遗传毒性物质。
The genotoxicity of fried rape oil was studied by micronucleus test of Swiss-Webster mouse medulla ossium. The results indicated:Fried repeseed oil could increase the percentages of SwissWebster mouse medulla ossium polycychromatic erythrocyte micronucleus,and the percentages ascended with the frying time;whereas fresh repeseed oil didn't pcassess the above effect to the percentagesof micronucleus. This supported strongly that some genetic toxicant appearsin fried repeseed oil,thusresults in the chromosome aberration.
