Vanilla planifolia Jacks. ex Andrews
Thai names: Wanila (in Bangkok), Vanilla
It was introduced into cultivation in the French Reunion Island from Central America in 1817 by way of Mauritius because of the high content of vanillin in its large, ﬂeshy seedpods which have a length of up to 15 cm. Today, vanilla comes from many sources which include Central America, Mauritius, Reunion, Madagascar, Indonesia, the Paciﬁc Islands, India (northeast India, Kerala, Karnataka, Tamil Naidu and Lakshadweep), the Andaman and Nicobar Islands, Thailand, Indochina and China. In its native Central America, it grows in damp forests up to 600 m. They are hand-pollinated in the Vanilla farms. The exported products are the vanilla pods which are variable in quality and contents from source to source as well as from batch to batch.
Fragrant Orchid: The major fragrance in vanilla pods is vanillin which accounts for about 2 % of the fermented fruit (range 1. 5–2.75 depending on provenance. However, vanillin is not present in newly harvested pods. It is formed during curing or fermentation when the precursor, non-volatile compound vanilloside (gluco-vanillin) undergoes beta-hydrolysis. Vanillin accounts for around 85 % of the volatile compounds. Another is p-hydroxybenzaldeyde (9 %), with p-hydroxybenzyl methyl ether accounting for 1 %
