The effect of using different polar solvents on the stability of thermal extraction phycocyanin from Spirulina platensis

Spirulina platensis is one type of blue-green autotrophic microalgae which is included in the cyanobacteria class. Spirulina platensis microscopically, it looks like a thin thread (filament) in the form of a spiral. Phycocyanin, and phycobiliprotein are used in food, biotechnology, and the cosmetics industry because of their color and antioxidants. This goal of research is to provide information of the best polar solvents on the thermal stability of phycocyanin extract from Spirullina platensis. The research method used was the complete random design (CRD) method. The results of the concentration and purity of phycocyanin showed that the heating process using 80°C for 60 minutes produced phycocyanin. The best polar solvent showe in etanol.
