One reality for Colombia is that the government has considered cocoa production to be of great economic importance and plans to progressively increase the areas under cultivation. In this context, only the seed, which represents approximately 10 % of the weight of the fruit, is used for cocoa production. The waste generated consists of the husk or pod, which is a focus for the propagation of pathogens of the Phytophora spp. genus, the main cause of economic losses in cocoa farming. Therefore, this project evaluated the potential use of cocoa pods of ICS-95 and CCN-51 clone based on bromatological, phytochemical, volatile material, and fixed carbon analyses of harvest residues. Laboratory tests were carried out at the Fundación Universitaria Agraria de Colombia - UNIAGRARIA, in the Nutrition and Animal Feeding laboratories, as well as in the Phytochemistry laboratory. The bromatological analysis and preliminary phytochemistry were carried out under the Colombian technical standard, while moisture was determined with the use of standard D3173-87, volatile matter with standard D3175-89 (02), ash with standard D3172-89 (02) and fixed carbon ignition with standard 3172- 89 (02); The latter, considered as the part that is not volatile and burns in solid state of the lignocellulosic material, establishing the difference between the sum of residual moisture, moisture, ash and volatile material and 100. The analysis of the data was carried out in the IBM SPSS Statistics package using a simple analysis of variance and a multiple range test for comparison of means. The comparative analysis of the variables shows a statistically significant difference in fixed carbon content according to the variety under study, but greater than 20% in both cases. The above results agree with those indicated for the % moisture, the response variables of the bromatological analysis, the phytochemical results, and the content of volatile compounds.
