Allicin is an organosulfur compound obtained from garlic and leeks. [1] When fresh garlic is chopped or crushed, the enzyme alliinase converts alliin into allicin, which is responsible for the aroma of fresh garlic. [2] Allicin is unstable and quickly changes into a series of other sulfur-containing compounds such as diallyl disulfide. [3]
The major volatile compounds responsible for garlic breath are allyl methyl sulfide, allyl methyl disulfide, allyl mercaptan, diallyl disulfide, dimethyl disulfide and methyl mercaptan, along with minor amounts of dimethyl selenide. [1] [2] [3] Various other sulfur compounds are also produced when allicin in garlic is broken down in the stomach ...
Diallyl disulfide and the related trisulfide are produced by decomposition of allicin, which is released upon breaking the cells of the Alliaceae plants, especially garlic. The diallyl disulfide yield is the highest for the steam distillation of garlic bulbs which contain about 2 wt.% of diallyl disulfide-rich oil. Diallyl disulfide can also be ...

Garlic cloves are used for consumption (raw or cooked) or for medicinal purposes. They have a characteristic pungent, spicy flavor that mellows and sweetens considerably with cooking. [51] The distinctive aroma is mainly due to organosulfur compounds including allicin present in fresh garlic cloves and ajoene which forms when they are crushed ...
Ajoene is also found in garlic extract. Ajoene is most stable and most abundant in macerate of garlic (chopped garlic in edible oil). The reaction sequence that forms ajoene (2 in the diagram) involves two molecules of allicin. First, one allicin molecule (1 in the diagram) fragments to form 2-propenesulfenic acid and thioacrolein. These two ...
The characteristic taste and odor of garlic is due to an oily, slightly yellow organosulfur compound S-Allyl prop-2-ene-1-sulfinothioate, commonly called allicin. Fresh garlic has little odor until it is chopped or crushed. Allicin is produced from alliin (a derivative of the amino acid cysteine) by the enzyme alliinase. [4]
