General description
二甲基三硫化物（DMTS）是一种挥发性硫化物（VSC）、 ，是油菜类蔬菜的主要香气成分。啤酒老化过程中会形成二甲基三硫化物。据报道，它是造成常见恶臭的真菌癌症样本。是一种重要的味觉和嗅觉（TO）引起的化合物在中国，主要与脓毒性/沼泽气味有关。它已通过微胞藻属鉴定为产生气味的常见化合物（腐烂时）。颗粒状活性炭（GAC）对藻类气味剂二甲基三硫化物的吸附已有报告。

Changes in the aroma of sake during aging were investigated by aroma extract dilution analysis (AEDA) and quantitative analysis using the stir bar sorptive extraction method. In AEDA, more odor zones were detected in aged sake than in fresh sake.

Some advanced cancer patients suffer from pungent sulfury malodor. To determine the chemical identity of the odorant, we performed gas chromatography-mass spectrometry-olfactometry analysis of volatiles from fungating cancer wounds. We identified the source of the characteristic smell as dimethyl trisulfide

Hop S-methylcysteine sulfoxide has previously been postulated as the precursor of dimethyl trisulfide (DMTS) in beers. The present data point to 3-methylthiopropionaldehyde, the Strecker aldehyde issued from methionine, as another potential precursor in aged beers. Spiking either fresh beer or
