A response surface methodology (RSM) was used for the determination of optimum water temperature and soaking time to produce an acceptable smooth kokum pulp. Kokum pulp was extracted using water extraction method at different temperature (13-33°C) and time (I0-50 min.) The effects of the extraction conditions on pulp recovery and HCA (Hydroxy citric acid) content were studying by employing a Central Composite Rotatable Design (CCRD). The coefficient of determination R for pulp recovery and HCA content were 0.94 and 0.86 respectively. Analysis of variable (ANOVA) performed on the experimental values showed that temperature and soaking time were the most important factors that affected characteristics of the kokum pulp as it exerted highly significant influence (p < 0.05) on all the dependant variables. An increase in soaking time and water temperature used for extraction of pulp resulted increase in pulp recovery and HCA content of the kokum pulp but to a certain level. Based on surface and contour plots optimum conditions for formation of smooth kokum pulp were 24.97°C temperature of water and soaking time of 30.42 min.
