A control experiment showed that cottonseed oil used in frying falafel developed significant mutagenic activity. As a result, one hundred samples of fresh and used cottonseed oil employed commercially for frying falafel were collected from restaurants in thirteen major cities of Egypt. Samples were examined for mutagenic activity using the Salmonella typhimurium assay with and without S9. Six of the heated oil samples showed significant mutagenic activity. None of the fresh unheated oil samples were mutagenic. Salmonella typhimurium TA 102 gave a higher response than did either TA 100 or TA 98. Peroxide, hydroxyl, acid and conjugated diene values were much higher for mutagenic samples. Iodine values, however, were lower. Liquid chromatography fractionation revealed that the mutagenicity was concentrated in the polar fraction. The column fraction having the highest mutagenic activity was further examined by chromatographic and spectroscopic techniques.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
