Dimethyl trisulfide is reported as a major aroma component in cooked Brassicaceous vegetables. Trap baits containing dimethyl trisulfide have been used to capture Calliphora loewi and other blowflies. Dimethyl trisulfide along with dimethyl sulfide and dimethyl disulfide have been confirmed as volatile compounds given off by the fly-attracting plant known as dead-horse arum (Helicodiceros muscivorus). These flies are attracted to the odor of fetid meat and help pollinate this plant.

ChEBI: Dimethyl trisulfide is an organic trisulfide.

It is produced by the microorganism, L. cremoris S2.

Taste characteristics at 2.0 ppm: sulfureous, alliaceous, gassy, savory and meaty with a fresh, vegetative nuance
