In this present, response surface methodology was used to investigate the procedure of agar gelling properties from Gracilariopsis persica agarophyte and optimization them formulation. Base on result, three independent variables - alkalinity concentration (2-8%), extraction temperature (90- 120°C) and extraction time (45-240 minutes) - in five levels on viscosity and hysteresis temperature were determined that effects of extraction time and temperature on viscosity and hysteresis temperature were significant (p<0.05). optimum conditions based on the highest viscosity and hysteresis temperature to be for alkalinity concentration, temperature and time extraction 3.2%, 110 °C and 200 minutes, respectively. predicted value were earned 24.7 cP and 65 °C for viscosity and hysteresis temperature, respectively, that were very close to the predicted data and were not statistically different (p>0.05).Journal
