Resumen
- Color is one of the sensory attributes that best define the quality of a food, however, to date there are no scientific investigations that record the study of superficial color of the fruit pulp of Musaceae, which provides useful information to identify promising materials destined for fresh consumption and agroindustrial processing. Surface color of plantain, Musa sp. (Musaceae) pulp from the Musaceae Germplasm Bank of the Corporación Colombiana de Investigación Agropecuaria (Agrosavia) was characterized. The CIEL*a*b* coordinates of the pulp of 25 plantain accessions were determined in triplicate using a colorimeter. From the coordinates of the surface color, parameters of chromaticity (C*), hue (hº), and color difference (ΔE) were calculated. Plantain accessions presented a range of L* (17.31-79.30), a* (8.73-30.64), and b* (15.24-95.49), C* (17.77) -98.22), hº 38.24-81.00) and ΔE* (147.07-6851.24). The plantain pulps can be classified colorimetrically among mild to intense yellows. Variation of the colorimetric coordinates a*, hº, and ΔΕ were adjusted to zero-order kinetics, and L*, b* and C* described a first-order kinetics. Accessions Benedetta, Cachaco espermo, Cachaco sin bellotae, Dominico mocho, Dominico mutant, GAEP-2, Hartón tigre and Maia Maoli Risaralda, are reported as promising materials for fresh consumption or agroindustrial processes, due to the low values of the constant speed kinetics (k) recorded in the present study.
