Research & Evidence
Dimethyl disulfide is a small volatile organosulfur compound responsible for part of the pungent, garlic- or cabbage-like aroma of truffles, alliums and various decomposing plant matter. It is an important flavor and aroma volatile and is also used industrially and as a fumigant.
Toxicity & Safety
At the trace concentrations present in foods it functions as an aroma compound. In concentrated industrial form it is an irritant with a powerful odor, and reported animal toxicity data (an oral LD50 in rats in the low-hundreds of mg/kg range) reflect bulk-chemical exposure rather than dietary intake.
