Title	Comparative proteomic from different cocoa genotypes to reveals new insights into the common and fine-flavor metabolism
Description	The organoleptic quality of cocoa beans relies on a combination of factors that include post-harvest processing and the genotype. Fine-flavor genotypes are characterized by their great organoleptic quality. Among these, the difference between the content of the storage proteins and endogenous enzymes from unfermented genotypes with contrasting organoleptic attributes are still poorly explored. Thus, in this study, the proteomic analysis of unfermented cocoa beans from four genotypes including CCN51, EET19, P7 and PA121 with different organoleptic profiles was performed. A total of 2015 proteins were identified, of which 198 were found significant differentially abundant proteins (DAPs) with respect to EET19 compared to at least one pairwise genotypes comparison. PCA was a useful tool to differentiate cocoa bean genotypes based on their DAPs. The higher abundant storage proteins were found in the high-flavor genotypes. Overall, this study shows that enzymes related to the release of flavor precursors are significantly differentially more expressed in the genotypes analysed
