Comparison of phytochemical characteristics pigmen extract (Antosianin) sweet purple potatoes powder (Ipomoea batatas L) and clitoria flower (Clitoria ternatea) as natural dye powder

Abstract

The purpose of our study was to obtain a comparison of anthocyanin pigment powder of butterfly pea and purple sweet potato with the best phytochemical characteristics. 10% addition of maltodextrin concentration in the butterfly pea resulted in the best characteristic with total of antosianin 53.02 mg / L, color intensity L * (brightness) of 51.72, a * (redness) of 23.50, b * (yellow) of 8.42, water content of 2,87% hygroscopicity of 8.33%, 97.33% of solubility, 187 seconds of soluble time, pH value of 2.93, and yield of 51.63%. For comparison the resulting 10% maltodextrin concentration in purple sweet potato with total anthocyanin of 48.43 mg / L, color intensity L * (brightness) of 37.86, a * (redness) of 43.66, b * (yellowish) of 21.68, water content of 5.56%, hygroscopicity of 11.62%, 97.13% of solubility, 159 seconds of soluble time, pH value of 3.04, and 31.38% of yield.
