Flavor synthetic chocolate

In addition to its uses as a herhal remedy, the primary use of cinnamaldehyde is as a food additive to enhance the flavor and/or odor of food products. It is used most commonly in cake mixes, chewing gums, chocolate products, synthetic cinnamon oils, cola drinks, ice creams, soft drinks, and vermouth. The compound is also added to a number of cosmetics and home care products to improve their odor. Such products include deodorants, detergents, mouthwashes, perfumes, sanitary napkins, soaps, and toothpastes. Finally, cinnamaldehyde is used to some extent in agriculture as an insecticide and fungicide.

Chocolate represents a highly complex flavor system for which no single character impact has been identified. Vanillin and Furaneol contribute to the sweet, caramel background character of milk chocolate (57). 5-Methyl-2-phenyl-2-hexenal provides a deep bitter, cocoa note, and is the aldol reaction product from phenylacetaldehyde and 3-methylbutanal, two Strecker aldehydes formed in chocolate (58). 2-Methoxy-5-methylpyrazine and isoamyl phenylacetate have chocolate, cocoa, nutty and cocoa-like notes, respectively, and both are used in synthetic chocolate flavors (59). Systematic studies of key odorants in milk chocolate were performed using aroma extract dilution analysis however, character impact compounds unique to chocolate flavor were not reported (57,60). 

The use of polyamide is advantageous because it separates natural from synthetic coloring material, removes sugars, acids, and flavoring materials, and concentrates dilute solutions of colors (156,167). However, the use of polyamide is not applicable to chocolate brown FB, chocolate brown HT, or indigotine, because the two chocolate browns are not completely eluted from the column and indigotine decomposes during extraction (157). 

Chocarom Pyrazine isomers were isolated from the skin and flesh of potato Solanum tuberosum L.) cultivars after baking 4). 3,5-Dimethyl-2-isobutylpyrazine [2,5-dimethyl-3-(2-methylpropyl)-pyrazine] was isolated by Oruna-Concha, Craig, Duckham and Ames from the following potato cultivars - Cara, Nadine, Flanna and Marfona. 3,6-Dimethyl-2-isobutyl-pyrazine [3,5-dimethyl-2-(2-methylpropyl)pyrazine], was found by the same team in Cara and Marfona potato cultivars. 2,5-Dimethyl-3-isobutylpyrazine was also detected by Welty, Marshall and Grun in chocolate ice cream prepared from cocoa flavor (5). Both pyrazines were also found as key odorant compounds in dark chocolate by Counet, Callemien, Ouwerx and Collin (6). The role of amino acids in alkyl-substituted pyrazines formation in model systems containing pyruvaldehyde was examined by Mea (7). 2,5-Dimethyl-3-isobutylpyrazine was formed in the model system with valine. Both isomers were prepared synthetically by Chen (S) by reacting acetol, isobutyraldehyde and ammonium acetate, with low yield of 22.3%. Subsequent proprietary work by the author has improved the yield to 65%.

By now it is clear that vanillin can be made from lignin, but why is synthetic vanillin needed at all The answer is quite simple there isn t enough natural vanillin to go round. The world currently consumes about 12,000 t of vanillin each year, only 18001 of which is produced in vanilla plants (e.g. Vanilla planifolid). Vanilla originates in Central America, and when Heman Cortes conquered the Aztee Empire, vanilla was already in use to flavor chocolate. Vanilla and cocoa arrived together in Europe in 1528 (—>2.22). 

For determination of macro constituents in relatively pure matrices, samples can be dissolved in an appropriate amount of a suitable pure solvent followed by spotting of an aliquot of solution on the layer. This approach was used for quantification of aspirin, acetaminophen, and caffeine in analgesic tablets dissolved in methanol (72) and allantoin in drug preparations dissolved in water (73). Natural or synthetic vanilla flavors were determined in chocolate by slurrying the sample with 95%...
