Abstract

     This experiment aimed to study the effect of salt solution and drying on the stability of the chlorophyll pigment in Chara corallina. The experiment was performed to study the effects of three solutions (ZnCl2, NaCl and NaHCO3),  the optimum conditions for maintaining the stability of chlorophyll pigments by using response surface methodology (RSM), and the stabilization of chlorophyll pigments with encapsulation using gum arabic and maltodextrin. For the results, NaHCO3 solution showed the best solution for maintaining stability of the chlorophyll pigment. The appropriate conditions for maintaining stability were 0.3% NaHCO3 concentration, 90°C for reaction temperature, and 10 minutes for the reaction time. The drying method to prepare pigment powder which was a complex compound of metals and chlorophyll (metallochlorophyll complexes) from Chara corallina was using spray drying machine. The spray drying process was performed to encapsulate chlorophyll pigment and a suitable encapsulating agent was maltodextrin. The results of the experiment can be used as guidelines for the production of natural pigments, to reduce the risk of using synthetic dyes. Additionally, it increases the benefits of chlorophyll and adds more value to Chara corallina, which is a local raw material.
