          Abstract

          Dentro de las condiciones para desarrollar el proceso de secado con aire caliente por convección forzada, se destacan por su importancia, la temperatura y la velocidad de flujo de aire, debido a su influencia en la velocidad de secado y el tiempo del proceso, al igual que en las características organolépticas del producto final. En este trabajo se determinaron temperatura y velocidad de flujo de aire óptima para deshidratar el ají tabasco (Capsicum frutescens). De esta forma una muestra de pasta del ají se sometió a secado a temperaturas de 40, 45, 50, 55, 60, 65 y 70 °C. Teniendo en cuenta las características del ají al final de secado y la forma como transcurrió el proceso, se eligió la más apropiada. Para el caso del flujo de aire, se realizó el secado, con la temperatura determinada anteriormente, pero graduando el voltaje del ventilador para obtener diferentes velocidades de flujo de aire y al realizar el respectivo análisis en cada lote determinar la más adecuada.

          Among the conditions for developing the process of hot air drying by forced convection, temperature and velocity of air flow are important due to its influence on the drying speed, processing time, and the organoleptic characteristics of the final product. In this research, the drying conditions for the dehydration of tabasco pepper (Capsicum frutescens), were analyzed to determine optimal temperature and flow rate of air. In this way, samples of pepper in slurry were subjected to drying at temperatures of 40, 45, 50, 55, 60, 65 and 70 °C, and taking into account the characteristics of the pepper at the end of drying and the performance of the process, the most appropriate conditions were chosen. In the case of the air flow, the drying was performed using the previously determined temperature that was held constant during drying, but graduating fan voltage to obtain different air flow rates and find the most suitable.

            Quantification, Antioxidant and Antimicrobial Activity of Phenolics Isolated from Different Extracts of Capsicum frutescens (Pimenta Malagueta)

            This paper presents the quantification, antioxidant and antimicrobial activity of capsaicin, dihydrocapsaicin and the flavonoid chrysoeriol isolated from different extracts (hexane and acetonitrile extracts from whole fruit, peel and seed) of Capsicum frutescens (pimenta malagueta). The acetonitrile extract of the seeds, peel and whole fruits contained capsaicin as a major component, followed in abundance by dihydrocapsaicin and chrysoeriol. The antimicrobial activity of the isolated compounds against seven microorganisms showed chrysoeriol was the most active compound. In the antioxidant test, the acetonitrile extract from the whole fruit showed the highest activity. The antioxidant activity of pimenta malagueta may be correlated with its phenolic content, principally with the most active compound, capsaicin.

              Cocoa Bean (Theobroma cacao L.)Drying Kinetics

              Cocoa (Theobroma cacao L.) is widely produced in West Africa and South America and is a great economic tree crop, with so many industrial uses. In this work, the experimental drying kinetics of foreign species was investigated, and the experiments were carried out under isothermal conditions, using heated batch drier at 55, 70 and 81 °C. The moisture ratio data obtained from change of moisture content with the drying time was fit to two thin layer drying model with good results. A faster drying process was observed at a higher drying temperature resulting in higher drying rates which is advantageous when evaluating costs. Fick’s second law of diffusion was used to predict effective diffusivity using experimental data assuming that the variation of diffusivity with temperature can be expressed by an Arrhenius type function, and the values of diffusivity obtained ranged from 6.137 x 10-10 to 2.1855 x 10-9 m2 s-1 for the temperature used. The Arrhenius constant (D) is predicted at 8.64 x 10-4 m2 s-1 while the activation energy was predicted at 39.94 kJ mol-1.
