Stabilitas Ekstrak Kurkumin Kunyit dan Klorofil Daun Pandan Menggunakan  Tocoferol dan Dekstrin

Abstract

Stability level of natural dyes is lower than synthetic dyes in treatment process, heating, and storage because natural dyes are easy to degrade or fade. The research was conducted to study the natural dyestuff manufacturing in the form of raw turmeric powder, pandan leaves which have a good stability in use as a food additive. The purpose of research was to get the optimum curcumin extract from turmeric and pandan leaves’s chlorophyll with variations of hot water used and pH. In the obtaining extract was used optimum a tocopherol and dextrins to get a dry powder of turmeric and pandan leaves. The result of research showed that the best pH solution for the extraction of turmeric was pH 4 at a heating temperature 600C with absorbance value 0.8539, while the optimum pH for chlorophyll extraction from Pandan leaves was pH 10 with absorbance value 0.9208. The use of 1-3% dextrin could increase the stability of the dyes.
