What Does Dark Chocolate Actually Smell Like?
A recent paper published in the Journal of Agricultural and Food Chemistry has described work carried out to analyze the overall aroma in dark chocolate – and gas chromatography was the main technique used. Previous work has been carried out on odorants in milk chocolate and cocoa mass and has identified 44 key odorants in milk chocolate, 37 in cocoa mass and 24 in cocoa powder. In dark chocolate, German scientists found almost 70 different aroma producing chemicals. Of these, almost 30 were present at levels high enough for us to smell.
