Abstract
This study aimed to determine the interaction between dextrin concentration and pH on the characteristics of a natural green dye powder from leaves of katuk foam-mat drying method. The experimental design used was a randomized block design (RAK) with a 3x3 factorial design with repetition as much as 3 times. The factors used is dextrin concentration (D) of 3 levels (d1 = 10%, d2 = 12.5%, 15%) and pH (P) (p1 = 7, p2 = 8, p3 = 9). The response in this study is the water content (%), chlorophyll content (%), organoleptic color and flavor. Best formulations in the preliminary study is a comparison katuk leaves and water is 1: 1. The products chosen on primary research by chemical response moisture content and chlorophyll content, and according to the response organoleptic based on attributes of color and flavor is a powder dye natural green of the leaf katuk with treatment d1p1 (d1 dextrin concentration of 10%, p1 pH 7). Keywords : Natural Dyes, Leaf Katuk, and Chlorophyll.
