Description

General description

Dimethyl trisulfide (DMTS), a volatile sulfur compound (VSC), is a major aroma consituent in cooked Brassicaceous vegetables. Dimethyl trisulfide formation is reported during beer aging. It has been reported to be responsible for common malodour from fungating cancer samples. It is an important taste and odor (T&O)-causing compound in China, mainly associated with the septic/swampy odor. It has been identified as a common odor-producing compound by Microcystis (on its decay). Granular activated carbon (GAC) adsorption of dimethyl trisulfide, an algal odorant, has been reported.

Application

• Exploring the binding affinity and characteristics of DcitOBP9 in citrus psyllids.: This study investigates the binding properties of dimethyl trisulfide (DMTS) with DcitOBP9, an odorant-binding protein in citrus psyllids, providing insights into the potential role of DMTS in pest management strategies (Pei et al., 2024).
