Effect of the addition of cocoa sweatings and time of fermentation on flavor compounds and sensory perception of 100% roasted cocoa liquor.

Fermentation is critical for producing high-quality cocoa, yet its kinetics and resulting chemical and sensory outcomes are poorly understood and thus difficult to manage. Cocoa sweatings (CS), the liquid runoff produced early during fermentation and typically drained off, may beneficially affect fermentation outcome when added back into the fermenting mass. Here, we report how back-addition of CS affects composition and sensory perception of roasted cocoa liquor after 5, 6, and 7 days of fermentation.
