Abstract

This study aimed to determine the effect of substitution of black rice flour (Oryza sativa L. Indica) on the physical, chemical and sensory characteristics of gandus cake. This study used a Non-Factoral Completely Randomized Design (CRD) with 6 levels of treatment and each treatment was repeated 3 times. The treatment was black rice flour substitution (0%, 20%, 40%, 60%, 80%, and 100%). Parameters observed included physical characteristics (color and texture), chemical characteristics (moisture content, ash content and antioxidant activity) and sensory characteristics using a preference test (hedonic) including color, taste and texture. The results showed that the substitution of black rice flour had a significant effect on color (lightness (L*), redness (a*) and yellowness (b*)), water content, ash content, and antioxidant activity, color, taste and texture on organoleptic tests. The treatment with the highest antioxidant activity value (IC50) was found in treatment F (100% black rice flour concentration (w/w)) with an IC50 value of 7866.74 ppm. The best treatment in this study was treatment E (black rice flour concentration 80% (w/w)) preference test value (3.28 for color, 3.12 for taste and 3.36 for texture), the physical characteristics of each 36.31% for lightness (L*), 5.42 for redness (a*), and 0.36 for yellowness (b*), 19.73gf for texture and chemical characteristics, 63.79% for each water content, 1.37% for ash content and IC50 of 8664.535 ppm. Keywords: gandus cake, black rice flour.
