一般描述
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。
应用

The vibrational theory of olfaction assumes that electron transfer occurs across odorants at the active sites of odorant receptors (ORs), serving as a sensitive measure of odorant vibrational frequencies, ultimately leading to olfactory perception. A previous study reported that human

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
