Abstract
This study purpose to determine the effect of added sappan wood extract to be sugar palm fruit natural colored toward characteristic sensory evaluation, activities of antioxidant, and to know the best concentrate of sappan wood extract with higgest characteristic sensory and antioxidant. The research design was used Completely Randomize Design with 6 treated exctract concentrating which is 0% ; 2% ; 4% ; 6% ; 8% ; 10%. The treatment was repeated three times so that have 18 unit experimental. Data were analyzed by Analysis of Variance (ANOVA) and then continued with Duncan Multiple Range Test (DMRT). Result of this shown that the extract concentrate have very significant effect towards activities antioxidant, and anthocyanin levels. Have significant effect towards color (hedonic test).
