Abstract: In this work the colour of orange and mandarin juices from different varieties was evaluated by two instrumental methods: spectroradiometry and digital image analysis. The effect of the deepness and the background, and the validity of the colorimetric parameters obtained by both methodologies were explored to discriminate between groups. It was concluded that both methods allowed the discrimination between orange and mandarin juices, being spectroradiometry which provides the best classification En este trabajo se evalúa el color de zumos de naranja y mandarinas de distintas variedades medidos por dos métodos instrumentales: espectrorradiometría y digitalización y análisis de imagen. Se estudia el efecto del espesor y del fondo, y se explora la utilidad de los parámetros colorimétricos medidos por ambos métodos para diferenciar entre grupos. Se concluye que ambas técnicas permiten la discriminación entre zumos de naranja y mandarina siendo la espectrorradiometría la que proporciona la mejor clasificación
