Dipropyl trisulfide Usage And Synthesis

Chemical Properties

Dipropyl trisulfide has a very powerful, diffusive, garlic-like odor.

Occurrence

Reported found as a volatile constituent in onion oil. Also found in roasted onion, shallot, onion, leek (raw), chive, nobiru (Allium grayi Regal), roasted peanut and durian (Durio zibethinus).

Uses

Dipropyl Trisulfide can be used to determine the antibrowning and antimicrobial effects of onion essential oil to preserve the quality of cut potatoes

Definition

ChEBI: Dipropyl trisulfide is an organic trisulfide.

Preparation

By adaptation of Westlake’s procedure.

Taste threshold values

Taste characteristics at 2.0 ppm: alliaceous, sulfurous, green and garlic-like with a tin-like metallic undernote and with minty and tropical nuances
