Physical and sensory characterization of 24 special cocoa genotypes Theobroma cacao
Colombia stands out as a country that produces fine and aroma cocoa; therefore, it is of great importance to explore the physical and sensory characteristics of the existing genetic diversity. For the present study, 22 genotypes from working collections with outstanding productive attributes and two recognized commercial controls were selected and evaluated for its productivity and sensory quality; the evaluated samples were taken according to a simple random sampling and a homogeneous, controlled, and independent post-harvest process was carried out by genotype, to obtain individual dry cocoa samples. Physical analyzes were carried out on the grain of each genotype and cocoa liquor was prepared with each of the samples obtained. Subsequently, each liquor was evaluated by means of the trained sensory evaluation panel, where the intensity of basic attributes, special attributes and acquired attributes characteristic of each sample was identified and quantified. The information was analyzed through descriptive statistics and principal component analysis, which allowed the identification of three outstanding genotypes by the grain index, and the husk percentage. The sensory analysis showed that, in seventeen genotypes, special attributes predominated such as: herbal, floral, fruity, dried fruit and sweet. These results are an important contribution for the selection of new high productivity varieties with sensory characteristics of interest for commercialization, which can be evaluated in different regions, to increase genetic availability in future renewal and planting programs of cocoa that is expanding in the different territories of the country.
