Most online reference entries and articles do not have page numbers. Although the exact route of vanillin biosynthesis in V. planifolia is currently unknown, several pathways are proposed for its biosynthesis. The vanilla beans require 10- 12 months to mature from the time of pollination. As harvested, the green seed pods contain vanillin in the form of its -D-glucoside; the green pods do not have the flavor or odor of vanilla.[29]. Vanillin was obtained from the oxidation of lignin, or from ferulic acid pathway or some other pathways. 4-hydroxy-3-methoxybenzaldehyde; 3-methoxy-4-hydroxybenzaldehyde; vanillic aldehyde, Slightly soluble in water; soluble in glycerol, ethyl alcohol, ether, and acetone. A carboxylic group was attached at the expense of a hydrogen ion. [8] In 1874, the German scientists Ferdinand Tiemann and Wilhelm Haarmann deduced its chemical structure, at the same time finding a synthesis for vanillin from coniferin, a glucoside of isoeugenol found in pine bark. But the disadvantage is that the production of vanillin is always low with these techniques. However, normal use levels of the material cause very little trouble in perfumes or functional products.

The aroma of vanilla pods developed during the fermentation process after picking. Washing with water also removes unreacted vanillin (if any) which is more soluble in water than the product. The Octanol/ Water partition coefficient was found to be 1.21 which indicates that vanillin is unlikely to bio accumulate. Its flavor is about three times as strong as that of methyl vanillin and is used to fortify or replace natural vanillin and lignin vanillin. Naturally, occurring Lignin is enzymatically decomposed to give various products, one of which is Coniferyl alcohol. The similarity of melting points of the obtained product and vanillin from literatures shows that the product obtained can be confirmed as vanillin.
