After being harvested, their flavor is developed by a months-long curing process, the details of which vary among vanilla-producing regions, but in broad terms it proceeds as follows: First, the seed pods are blanched in hot water, to arrest the processes of the living plant tissues. /StructParents 2 endobj with traces of Iron (e.g. /MediaBox [0 0 595.3200073242 841.9199829102] This is the only truly synthetic method of importance, All other methods are based upon a natural starting material, closely related to vanillin in chemical structure. It is a phenolic aldehyde. It is also reported to be present in elderberry juice, blueberries, orange juice, strawberries, passion fruit juice, leeches, and wines. Vanillin will often produce off-color with Anthranilates, indoles, quinolines. stream Vanillin has a low flavor threshold value of 20g/L in water at 20 C.11Although more than 12000 tonnes of vanillin are produced each year only 1% of it comes from the natural sources and the rest are synthesized by chemical synthesis.12 Moreover, the high demand for vanillin and the fact that the vanillin derived from plants is relatively expensive ($1200- 1400 per kilo compared to synthetically produced which is <$15 per kilo), because of causes such as scare availability of vanilla pods, climate associated fluctuations of the harvest yields, labour-intensive cultivation, pollination, harvesting and curing of pods.13, These reasons has led to the exploration of other biotechnological routes such as the microbial production from phenolic stilbenes, lignin, eugenol, and ferulic acid.8, 11 Vanillin can be obtained from chemical synthesis, biotransformation or from degradation of waste sulphite liquors.11. Equilibrium mole fraction solubility of vanillin in nine aqueous-ethanolic mixtures, as well as in neat water and neat ethanol, was determined at seven temperatures from T=293.15 to T=323.15K.

They proposed a very complex process in which caffeic acid was first methylated at 4- position to iso-ferulic acid which was then further methylated at 3-position to produce 3,4- dimethoxycinnamic acid. Then the reaction was allowed to precipitate for 10 min. The production of vanillin is a very long and expensive process which involves large number of steps as well. Because the microbe is a processing aid, the resulting vanillin would not fall under U.S. GMO labeling requirements, and because the production is nonpetrochemical, food using the ingredient can claim to contain "no artificial ingredients".[38]. /CropBox [0 0 595.3200073242 841.9199829102] /Contents 60 0 R endobj The solution was transferred to a separating funnel and the organic phase was removed.

[12] However, subsequent developments in the wood pulp industry have made its lignin wastes less attractive as a raw material for vanillin synthesis. Vanillin was first synthesized from eugenol (found in oil of clove) in 187475, less than 20 years after it was first identified and isolated. [36] The resulting vanillylmandelic acid (2) is then converted by 4-Hydroxy-3-methoxyphenylglyoxylic acid (3) to vanillin (4) by oxidative decarboxylation.[14].
