<![CDATA[Tapak dara flower (Catharanthus roseus) is an ornamental plant originating from Central Amerika. This natural pigment derived from the tapak dara flower is made in powder with maltodextrin as a drying agent. This experimental study uses a one-factor, Completely Randomized Design (CRD) research method with 3 levels of maltodextrin concentration, namely 20%, 30%, and 40%. The data obtained were analyzed statistically using the ANOVA test and continued with the DMRT as a posthoc test if there were significant differences. The results showed that adding maltodextrin with concentrations of 20%, 30%, and 40% and repeated twice had significant differences in water content, pH, level of sweetness (°brix), color, solubility, and total dissolved solids. The results of the chemical analysis of tapak dara corolla dye powder with a maltodextrin concentration of 40% had a water content, and the lowest pH was a water content of 4,90% and a pH value of 3,41. Maltodextrin concentration of 20% has the lowest sweetness level (°brix) of 5,35%. The results of the physical properties study showed that tapak dara corolla dye powder with 40% maltodextrin concentration had the lowest color brightness level (L*) of 32,91; the lowest reddish color level (a*) of 35,26 and yellowish color level (b*) the lowest is 35,26. The concentration of 20% maltodextrin has the lowest solubility and total dissolved solids, namely the solubility of 92,84% and the total dissolved solids of 5,35%. Adding maltodextrin with a concentration of 30% gave the best dye results based on water content, pH, level of sweetness (°brix), color, solubility, and total dissolved solids using the De Garmo method.]]>
