O mnie

Vanilin, methyl vanilin, or 4-hydroxy-3-methoxybenzaldehyde, is an organic compound with the molecular formula C8H8O3. Its functional groups include aldehyde, ether, and phenol. It is the primary component of the extract of the vanila bean. Synthetic vanilin, instead of natural vanila extract, is sometimes used as a flavoring agent in foods, beverages, and pharmaceuticals.

Methyl vanilin is used by the food industry as well as ethylvanilin. The ethyl is more expensive but has a stronger note. It differs from vanilin by having an ethoxy group (-O-CH2CH3) instead of a methoxy group (-O-CH3).

Natural "vanila extract" is a mixture of several hundred different compounds in addition to vanilin. Artificial vanila flavoring is a solution of pure vanilin, usually of synthetic origin. Because of the scarcity and expense of natural vanila extract, there has long been interest in the synthetic preparation of its predominant component. The first commercial synthesis of vanilin began with the more readily available natural compound eugenol. Today, artificial vanilin is made from either guaiacol or from lignin, a constituent of wood which is a byproduct of the paper industry.

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 in the lignin-derived product, an impurity not found in vanilin synthesized from guaiacol.[2]
