The analysis of product confirmed the conversion of mandelic acid derivatives to protocatechualdehyde. 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, a minor component in the lignin-derived product that is not found in vanillin synthesized from guaiacol. Should never be stored in contact with iron. >> endobj Vanillin is also used in the fragrance industry, in perfumes, and to mask unpleasant odors or tastes in medicines, livestock fodder, and cleaning products.

Because of the scarcity and expense of natural vanilla extract, synthetic preparation of its predominant component has long been of interest. In mango, vanillin is present both as free vanillin and vanillyl glucoside. Either of these compounds is then treated with acetic anhydride ((CH3CO)2O) to obtain vanillin acetate, which is then converted to pure vanillin. Background endobj this should not be translated so that Vanillin is not an offender in a soap perfume. These components may add somewhat different flavors and aromas, modifying the pure taste and smell of vanillin. The solubility of CS decreases in a neutral medium, and CS combines into larger particles (Hu et al., 2005); thus, the formed emulsion has a larger particle size. The remaining 99 percent comes from lignin or is produced by synthetic means. Chemical Compounds. The fingerprint region for protocatechualdehyde was found to be at 1710.2 cm-1 which matches with the standard for -C=O stretch for aromatic aldehyde as shown by the IR correlation tables.
