描述
Flavouring agent. Isolated from higher plants, e.g. radish (Raphanus sativus), also present in orange juice, pineapple, strawberries, asparagus, wheatbread, gruyere cheese, hop oil, coffee, roasted filberts, cooked rice and other foods
Methanethiol (also known as methyl mercaptan) is a colorless gas that smells like rotten cabbage. It is a natural substance found in the blood, brain, and other tissues of people and animals. It is released from animal feces. It occurs naturally in certain foods, such as some nuts and cheese. It is also one of the main chemicals responsible for bad breath and flatulence. At very high concentrations methanethiol is highly toxic and affects the central nervous system. The chemical formula for methanethiol is CH3SH; Methanethiol (also known as methyl mercaptan) is a colorless gas with a smell like rotten cabbage. It is a natural substance found in the blood, brain, and other animal as well as plant tissues. It is disposed of through animal feces. It occurs naturally in certain foods, such as some nuts and cheese. It is also one of the main chemicals responsible for bad breath and the smell of flatus. The chemical formula for methanethiol is CH3SH; it is classified as a thiol.; Methanethiol is a byproduct produced by the metabolism of asparagus in 40-50% of people. The ability to detect the presence of methanethiol is also a genetic trait, and these traits are inherited separately. It is responsible for a noticeable change in the odor of urine, as soon as a few hours after eating asparagus.; Methanethiol is a weak acid, with a pKa of ~10.4. This acidic property makes it reactive with dissolved metals in aqueous solutions. The environmental chemistry of these interactions in seawater or fresh water environments such as lakes has yet to be fully investigated.; it is classified as a thiol. Methanethiol is also considered to be a weak acid, with a pKa of ~10.4. This acidic property makes it reactive with dissolved metals in aqueous solutions. The environmental chemistry of these interactions in seawater or fresh water environments such as lakes has yet to be fully investigated. -- Wikipedia.
