ABSTRACT

Black powdered colorant from carbonized merang can be used as a ready-to-use colorant in making traditional product ireng-ireng. The aim of this study was to determine the effect of various black powdered colorant concentrations as well as to obtain the optimum concentration of the colorant on the physical properties of ireng-ireng product, such as lightness (L*), redness (a*), yellowness (b*) and texture profile (hardness, springiness, cohesiveness, gumminess, chewiness) The research used one factor completely randomized design (CRD). The factor used was colorant concentration (1%, 3%, 5%, 7% (w/v)). Each treatment level was repeated three times to obtain 12 experimental units. The data were analyzed using ANOVA with a 95% confidence interval and continued by Tukey's HSD test of 5%. Ireng-ireng from the optimum concentration (addition of 7% colorant) based on Multiple Attribute Zeleny had lightness (L*) 23.02 ± 0.61, redness (a*) -0.97 ± 0.06, yellowness (b*) 5.05 ± 0.18, hardness 43.6 ± 7.19, cohesiveness 0.85 ± 0.07, springiness 8.9 ± 0.31, gumminess 36.70 ± 3.96, and chewiness 327.86 ± 40.97.
