| dc.description.abstract | Objetivo: Determinar el efecto del tiempo y la temperatura en el color generado por el tostado del café. Material y Método: Estudio de investigación tecnológica aplicada para lo cual se desarrolló e implemento una herramienta informática en el software matemático MATLAB, previamente parametrizado usando datos del color durante el proceso de tostado. Resultados: El color se midió en el espacio CIEL*a*b* y los datos se analizaron usando el diseño estadístico de superficie de respuesta. Conclusiones: Las mediciones determinaron que el valor de L disminuye significativamente cuando el tiempo se incrementa, desplazándose hacia 0 lo cual corroboró que el café adquirió tonalidades oscuras a medida que se incrementa el tiempo de tostado. Con respecto a los valores de a y b, estos varían en función al tiempo en forma directa e inversamente proporcional respectivamente. | spa |

The studyshows that computer vision system could distinguishdifferent shades during roasting of coffee depending onprocess parameters and good capacity for generalization. | eng |
