The European Parliament registered cinnamyl acetate as both a flavouring substance and a cosmetic compound in 1996. [14] [15] The Joint (FAO/WHO) Expert Committee on Food Additives described in 2000 that “the substance does not present a safety concern at current levels of intake when used as a flavouring agent”.

Jasminaldehyde used in industry is commonly derived not from jasmine essential oil, but ultimately from the castor bean plant. The process starts with ricinoleic acid, the principal constituent of castor oil.
Cinnamaldehyde is an organic compound with the formula C 9 H 8 O or C 6 H 6 CH=CHCHO. Occurring naturally as predominantly the trans ( E ) isomer, it gives cinnamon its flavor and odor . [ 1 ] It is a phenylpropanoid that is naturally synthesized by the shikimate pathway . [ 2 ]

The commercial material often contains low levels of 2,6-di-tert-butyl-4-methoxyphenol as a stabilizer. It is a derivative of cinnamaldehyde with a hexyl substituent. One supplier reported that its hexyl cinnamaldehyde (or "hexyl cinnamic aldehyde") contained at least 90% trans isomer. [2]

1,1-Diethoxyethane (acetaldehyde diethyl acetal) is a major flavoring component of distilled beverages, especially malt whisky [3] and sherry. [4] Although it is just one of many compounds containing an acetal functional group, this specific chemical is sometimes called simply acetal .
The equilibrium constant is 6 × 10 −7 at room temperature, thus that the relative amount of the enol form in a sample of acetaldehyde is very small. [27] At room temperature, acetaldehyde ( CH 3 CH=O ) is more stable than vinyl alcohol ( CH 2 =CHOH ) by 42.7 kJ/mol: [ 28 ] Overall the keto-enol tautomerization occurs slowly but is catalyzed ...
