| Research Abstract |
Trans-fatty acid (TFA) was detected in some dietary oils (0.3-1.93g/100g). However, the concentration of TFA was decreased by heating. Though glycidol fatty acid ester (GE) was determined in oils, the levelof GE was also decreased by heating. Treatment of GE showed the siginificantly genotoxcities (reverse mutation, DNA damages and the frequency of micronuclei) in Ames test(TA100), COMET assay and micronuclei test compared to non-treated groups. The concentration of GE in comminuted pig meat heated with charcoal firewas very high (195g/100g meat). From these results, it is demonstrated that we are habitually exposed to TFA and GE that have an influence on the health of human from daily foods. It is important to estimate the risk of these chemicals to human.
