Vanillin is an organic compound with the molecular formula C 8 H 8 O 3. It is a phenolic aldehyde. ... Traces of vanillin were also found in wine jars in Jerusalem, ...
Most artificial vanilla products contain vanillin, which can be produced synthetically from lignin, a natural polymer found in wood. Most synthetic vanillin is a byproduct from the pulp used in papermaking, in which the lignin is broken down using sulfites or sulfates. However, vanillin is only one of 171 identified aromatic components of real ...
An estimated 85% of the world's supply of vanillin comes from guaiacol. Because consumers tend to prefer natural vanillin to synthetic vanillin, methods such as microbial fermentation have been adopted. The route entails the condensation reaction of glyoxylic acid with guaiacol to give mandelic acid, which is oxidized to produce phenylglyoxylic ...
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 ...
Vanillin makes up 80% of the total aromatic compounds found in the pods, in contrast to the 50% content of Vanilla × tahitensis pods. Some of the other chemicals found in lesser amounts in the pods of Vanilla planifolia such as guaiacol, 4-methylguaiacol, acetovanilone, and vanillic alcohol also contribute to the perception of a vanilla flavor ...
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]

Vanillin is a phenolic aldehyde most commonly associated with the vanilla notes in wines that have been aged in oak. Trace amounts of vanillin are found naturally in grapes, but they are most prominent in the lignin structure of oak barrels. Newer barrels will impart more vanillin, with the concentration present decreasing with each subsequent ...
