Sulfur compounds, such as hydrogen sulfide, dimethyl sulfide, and dimethyl disulfide, are famous for their pungent odor and very low odor thresholds. It has a role as a bacterial xenobiotic metabolite, a marine metabolite, an EC 3.5.1.4 (amidase) inhibitor, an algal metabolite and an Escherichia coli metabolite. Dimethyl trisulfide has been found in volatiles emitted from cooked onion, leek and other Allium species, from broccoli and cabbage, as well as from Limburger cheese, and is involved in the unpalatable aroma of aged beer and stale Japanese sake. DMS adds the “ripe” note to berry flavors and it has been found as one of the hundred plus aroma constituents in strawberry, blackberry and raspberry fruit.Some other foods that DMS has been isolated from include: peppermint, spearmint, geranium, tomato, grapefruit,mango, wine and A flavor chemist must handle DMS very careful. Some research points to dimethyl sulfide being the primary odor-producing component in the breath of fetor hepaticus. The usual level of added DMS that ends up in a consumer product  works out to be 0.1-2 parts per million (PPM). For all uses of dimethyl sulfoxide: Irritation where dimethyl sulfoxide is used. This is a very small  but powerful amount. It becomes highly disagreeable at even quite low concentrations. This may last for up to 72 hours after you get dimethyl sulfoxide. There are many extremely potent sulfur based flavoring compounds, and their ease of oxidation or decomposition often poses special challenges. These are … It is a component of the smell produced from cooking of certain vegetables, notably maize, cabbage, beetroot and seafoods. A flavor chemist has to see the beauty DMS has to offer.Flavor scientists use DMS in seafood or meat flavors, like crab or chicken and in milk, butter, egg, mayonnaise, malt, vegetable, and fruit flavors.

Dimethyl trisulfide is the major cause of off-flavour in overcooked Brassica vegetables. It is a decomposition product of bacterial decomposition, including the early stages of human decomposition, and is a major attractant for blowflies looking for hosts. Dimethyl trisulfide along with dimethyl sulfide and dimethyl disulfidehave been confirmed as volatile com…

DMS smells terrible and can politely be described as canned creamed corn. DMS originates primarily from DMSP, a major secondary metabolite in some DMS is oxidized in the marine atmosphere to various sulfur-containing compounds, such as Marine phytoplankton also produce dimethyl sulfide,Dimethyl sulfide is normally present at very low levels in healthy people, namely <7nM in blood, <3 nM in urine and 0.13 – 0.65 nM on expired breath.At pathologically dangerous concentrations, this is known as dimethylsulfidemia. Flavor compounders and flavor chemists have to be very careful not to make math errors when formulating with DMS, or they may have someone ask “What’s that smell?”Pure diluted dimethyl sulfide smell is best described as boiled cabbage and rotting seaweed.There are many extremely potent sulfur based flavoring compounds, and their ease of oxidation or decomposition often poses special challenges. These are some questions you may ask when you walk into a flavor lab where the chemist has been using Dimethyl sulfide (DMS). One really interesting flavorful compound is dimethyl trisulfide MeSSSMe, it falls apart at around 50 C.

It is produced naturally by some marine algae. The Personally, I like to keep a 0.1% dilution of DMS handy for modifying flavors that I create. Opinions and reviews are my own.

Dimethyl sulfide (DMS) or methylthiomethane is an organosulfur compound with the formula (CH3)2S.
