Vanillin is an organic compound with the molecular formula C 8 H 8 O 3. It is a phenolic aldehyde. Its functional groups include aldehyde, hydroxyl, and ether. It is the primary component of the extract of the vanilla bean. Synthetic vanillin is now used more often than natural vanilla extract as a flavoring in foods, beverages, and ...
ortho-Vanillin is harmful if ingested, irritating to eyes, skin and respiratory system, but has an unmistakable high LD 50 of 1330 mg/kg in mice. [7] It is a weak inhibitor of tyrosinase, [8] and displays both antimutagenic and comutagenic properties in Escherichia coli. [9] However, its net effect makes it a “potent comutagen”. [10]
Synthetic essence consists of a solution of synthetic vanillin in ethanol. The chemical compound vanillin (4-hydroxy-3-methoxybenzaldehyde) is a major contributor to the characteristic flavor and aroma of real vanilla and is the main flavor component of cured vanilla beans. [40] Vanillin was first isolated from vanilla pods by Gobley in 1858. [41]
Vanillylamine is produced from vanillin by the enzyme vanillin aminotransferase. [2] It is then converted with 8-methyl-6-nonenoic acid into capsaicin by the enzyme capsaicin synthase . [ 2 ]
Glucovanillin, also known as vanilloside, is a chemical compound found in vanilla beans.Chemically, it is a glucoside composed of glucose and vanillin.Glucovanillin is particularly prevalent in green vanilla beans [2] and upon ripening it is hydrolyzed by the action of the enzyme β-glucosidase which releases vanillin, [3] [4] the major contributor to the aroma and flavor of vanilla.
A number of vanilloids, most notably capsaicin, bind to the transient receptor potential vanilloid type 1 (TRPV1) receptor, an ion channel which naturally responds to noxious stimuli such as high temperatures and acidic pH. [1]
Regarded as the world's most popular aroma and flavor, [12] vanilla contains the phenolic aldehyde, vanillin, as well as anisaldehyde, together accounting for its predominant sensory characteristics. [5] Vanilla is a widely used aroma and flavor compound for foods, beverages and cosmetics, [4] [12] as indicated by its popularity as an ice cream ...
Isovanillin is a phenolic aldehyde, an organic compound and isomer of vanillin. [2] It is a selective inhibitor of aldehyde oxidase.It is not a substrate of that enzyme, and is metabolized by aldehyde dehydrogenase into isovanillic acid, which could make it a candidate drug for use in alcohol aversion therapy.
