Resumen

LEONELLI CANTERGIANI, Gina N et al. Heterogeneity in color of merkén formulations prepared from ecotypes of chili pepper (Capsicum annuum L.) cv. "Cacho de cabra". Idesia [online]. 2011, vol.29, n.3, pp.109-115. ISSN 0718-3429.  http://dx.doi.org/10.4067/S0718-34292011000300017.

The study was conducted to evaluate the heterogeneity of color in samples of merkén produced from ecotypes of pepper, Capsicum annuum L. cv. "Cacho de cabra" cultivated in the Araucania and Maule Regions of Chile. Color assessment was made by the quantification of carotenoids, especifically red carotenoids (R) and yellow-orange carotenoids (A). Moreover, we used the color system Cielab to evaluate the coordinates of lightness (L*), green-red component (a*), blue-yellow component (b*), chroma (C*) and hue (H*). The formulation that showed the highest content of carotenoids (R) and (A) was Merkén UCT005, in addition this formulation had highest value in the variables L *, a *, b * and C *. Merkén UCT003 obtained the highest value for H*. Therefore, the pepper cv. "Cacho de cabra" from the Araucanía Region is recommended for optimum merkén formulation from the standpoint of color. Since the color is a quality index, it is advisable to use pepper cv. "Cacho de cabra" from the Araucanía Region for merkén optimal formulation from the standpoint color: this variety also proved to have a higher content of carotenoids.

Palabras clave : Capsicum; merkén; carotenoids; Cacho de cabra; pepper.
