Chemistry and Physics of Vanillin in Personal Care Applications.
Symposium on High Function Naturals, New York, NY April 13, 2004
http://www.cosmeticpackaginganddesign.com/meetings/meetings.htm

Abstract: A tendency to aggregate influences the behavior of vanillin, a primary aroma constituent in vanilla flavor. Aggregation, that is, propensity for self-association restrains the volatility of vanillin (below a critical temperature) and the escape tendency from aqueous solutions. Escape tendency of vanillin in water is proportional to the solubility of the compound and solubility, in turn, is enhanced by alkaline conditions and increase in temperature. Enhanced solubility augments also the chemical reactivity of the carbonyl group in vanillin, e.g., Schiff base formation, thereby leading to depletion and negation of aromatic efficacy of vanillin. Conditions, which influence aggregation or solubility
of vanillin in aqueous media, may determine the physical and chemical fate of vanillin in formulations for personal care products.

 

A hairy tissue produces vanillin.
Israel Journal of Plant Sciences Vol. 51 2003 pp. 157–159.
A unique secretory tissue produces the most important flavoring agent. Vanillin accumulates in the secretion around the seeds in the mature fruit of the vanilla orchid. A unique secretory tissue that is composed of closely packed unicellular hairs is located in the three gaps between the placentas along the central fruit cavity. These cells contain enzymes that are involved in vanillin biosyntheis and seem to be responsible for vanillin secretion.

 

Interrelation of curing and botany in Vanilla (Vanilla planifolia) bean.
The fruit of the climbing orchid Vanilla planifolia (vanilla bean) is used for the  commercial production of the prized vanilla flavor, consisting of vanillin and other numerous flavor compounds, with the use of a curing process. However, present curing methods yield only a fraction of the vanilla flavor from flavor precursors in green beans. Studies on the botany of vanilla beans revealed that flavor precursors are found in the bean interior, where they are secreted onto the placental region around the seeds, whereas hydrolytic or other degradative enzymes, which catalyze the release of the flavor precursors to flavor compounds, are localized mostly in the outer fruit wall region. This insight suggests that the objective of killing, the first curing stage carried out by hot water scalding, freezing or by other methods, is to disorganize the bean tissue, such that contact is created between substrates and their respective enzymes. Sweating, a subsequent step in curing, entailing high temperatures (usually around 45º to 65º C) and high humidity, provides conditions for enzyme-catalyzed production of flavor compounds and also for non-enzymatic reactions. The objective of the final curing steps, including drying and conditioning, is to dry the cured beans to preserve the formed flavor compounds. Further understanding on the botany and curing of the vanilla bean may render a full recovery of flavor from the flavor precursors in vanilla beans and, subsequently, significant economic gains.
