Chemical Information
FooDB NameEthyl methyl disulfide
DescriptionEthyl methyl disulfide belongs to the class of organic compounds known as dialkyldisulfides. These are organic compounds containing a disulfide group R-SS-R' where R and R' are both alkyl groups. Ethyl methyl disulfide is a sulfurous and truffle tasting compound. Ethyl methyl disulfide is found, on average, in the highest concentration within kohlrabis (Brassica oleracea var. gongylodes). Ethyl methyl disulfide has also been detected, but not quantified in, several different foods, such as green onion, garden onion (var.), cabbages (Brassica oleracea var. capitata), fruits, and welsh onions (Allium fistulosum). This could make ethyl methyl disulfide a potential biomarker for the consumption of these foods. Based on a literature review very few articles have been published on Ethyl methyl disulfide.
