Vanillin is a
phenolic aldehyde, which is an
organic compound with the molecular formula C8H8O3. 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 agent in foods, beverages, and pharmaceuticals.
Vanillin and
ethylvanillin are used by the food industry; ethylvanillin is more expensive, but has a stronger note. It differs from vanillin by having an ethoxy group (–O–CH2CH3) instead of a methoxy group (–O–CH3).
Natural "
vanilla extract" is a mixture of several hundred different compounds in addition to vanillin. Artificial vanilla flavoring is often a solution of pure vanillin, usually of synthetic origin. Because of the scarcity and expense of natural vanilla extract, synthetic preparation of its predominant component has long been of interest. The first commercial synthesis of vanillin began with the more readily available natural compound
eugenol. Today, artificial vanillin is made either from
guaiacol or
lignin.
Vanillin crystals extracted from vanilla extract
Lignin-based artificial vanilla flavoring is alleged to have a richer flavor profile than oil-based flavoring; the difference is due to the presence of
acetovanillone, a minor component in the lignin-derived product that is not found in vanillin synthesized from guaiacol.

Id imagine most vanilla flavors have vanillin in it as a ingredient. using vanillin or vanillin crystals in tiny amounts will boost the vanilla flavor and may add a little sweetness and gives it a fake vanilla flavor. I personally dont care for it and havent found to many uses for it nor do I get any added vanila boost when I use it, normally I just get a stomach ache and the opportunity to re wick my atty lol. HIC did do the bubble gum with it but to me its just another additive that kinda useless. for me using the right flavors for the application is much better than trying to force something with additives.
