 "A number of compounds have been identified by gas chromatography-olfactometry (GC-O) as key odorant compounds in dark chocolate. 2-Methylpropanal, 3-methylpropanal and 2-methylbutanal have been related to chocolate odors while trimethylpyrazine, 2,5-dimethylpyrazine and acetylpyrrole have been attributed cocoa odors. Methylpyrazine, 2,3-dimethylpyrazine, 2-ethyl-6-methylpyrazine and benzaldehyde added a hazelnut/almond note to the aroma profile of chocolate; ethylpyrazine, 3-ethyl-2,5-dimethylpyrazine and tetramethylpyrazine a roasty note." \\ "A number of compounds have been identified by gas chromatography-olfactometry (GC-O) as key odorant compounds in dark chocolate. 2-Methylpropanal, 3-methylpropanal and 2-methylbutanal have been related to chocolate odors while trimethylpyrazine, 2,5-dimethylpyrazine and acetylpyrrole have been attributed cocoa odors.

 +"The specific cocoa aroma arises from complex biochemical and chemical reactions during the postharvest processing of raw beans, and from many influences of the cocoa genotype, chemical make‐up of raw seeds, environmental conditions, farming practices, processing, and manufacturing stages. There has been much research on cocoa flavor components. However, the relationships between all chemical components that are likely to play a role in cocoa flavor, their sensory properties, and the sources and mechanisms of flavor formation are not fully understood." \\
