Abstract

As part of a program to determine the underlying factors responsible for genotoxicity and perhaps lung cancer risk in Chinese women, we qualitatively identified the volatile components emitted during the heating of cooking oils to 265 degrees C. 1,3-Butadiene, benzene, and a series of aldehydes, olefins, and saturated hydrocarbons were elucidated in vapors from Chinese rapeseed oil. On a relative basis, the intensity of 1,3-butadiene vapors from this were 15.7-, 6.3-, and 1.4-fold greater than in the vapors from peanut, soybean, and Canola oils, respectively. Thus, the Chinese rapeseed oil yielded a higher emission rate of 1,3-butadiene than the other three oils investigated. The benzene formation rate followed a similar trend, i.e., its intensity in Chinese rapeseed oil was 14-, 6.6-, and 1.7-fold greater than in vapors from peanut, soybean, and Canola oils, respectively.
