n Colombia, cocoa cultivation is a good alternative for the high

and growing demand for cocoa in the world, especially for fine

and flavor cocoa. Colombia’s production zone has a privileged

geographic position for cultivating this type of cocoa. However,

many factors influence its quality. One of these factors is the

fermentation process, as is the stage where the formation of flavor

precursors takes place. Then the quality of fine and flavor cocoa

could be lost if the fermentation is not carried out under certain

conditions. This project looks at getting a better understanding

of how the fermentation process is carried out in three different

places in Colombia and how these practices could affect the

cocoa quality. We controlled the fermentation process each 24

hours, analyzing the change in different variables such as pH, total

acidity, sugar content, total polyphenols, theobromine, caffeine,

reducing sugars, proteins and amino acids. Moreover, we analyzed

the aromatic profile, and the sensorial analysis of the cocoa

produced. Results showed significant differences in quality of the

cocoa, but neither of them released distinctive aromatic notes

that allow classifying such as fine and flavor cocoa. However, we

have identified two factors that are mainly responsible for this

behavior, the temperature, and the pH, which never reaches the

value required according to literature, for the optimal activity of

endogenous enzymes involved in the degradation of bean proteins

and the generation of various flavor precursors.
