Abstract

El color de las materias primas incide en la aceptación o rechazo por parte del consumidor. Este trabajo estudia cómo se modifica la apariencia amarillenta del talco por adición de pigmentos, brindando una apariencia visual más blanca. Los resultados presentan un método para la evaluación colorimétrica de agregados en polvo, así como para determinar la dispersión de la luz incidente como una aplicación espectrofotométrica en la determinación de parámetros de la medida del color tales como: Las coordenadas colorimétricas CIELAB, ΔE y la blancura, mediante las curvas de reflectancia para el talco con y sin pigmento
