EFFECT OF MALTODEXTRIN CONCENTRATION ON ANTIOXIDANTS ACTIVITY AND STABILITY OF NATURAL COLORING POWDER OF SECANG WOOD (CAESALPINIA SAPPAN L) IN VARIOUS CONDITIONS OF PH AND TEMPERATURE

This research was aimed to determine the effect of different concentrations maltodextrin on antioxidants and stability natural dye powder sappan wood under various pH temperature conditions. study used a completely randomized experimental design with five treatments three replications. The in this were: A (addition 5%), B 10%), C 15%), D 20%), E 25%). Before drying process, added extract that had been created. Yield, color analysis, solubility test, test based heating fluctuations, water content, antioxidant activity are among observations made. addition substansial impact yield, substantial solubility, activity, according findings. best treatment 5%) characteristics yield 18.33,%, hue value analysis 39,58%, yellow red color, 87,33%, content 6,83, 17,80 ppm (strong category), as well which stable against treatments.
