ABSTRACT
India is the leading country in the production of coir contributing about 60% of the world’s production. This study focusses on recovery of reducing sugars from tender coir using hot water pretreatment method. For pretreatment, three independent factors—biomass (X1, mg/ml), time (X2, min), and temperature, (X3, °C) and one dependent factor—reducing sugar (Yrs, %), were considered. ANOVA and optimization were done using Statistica, a statistical software. The second order model obtained after multiple regression analysis was found to be significant since the model p-value was less than 0.05. The coefficient of determination (R2) was 0.97 and adjusted R2 was 0.95. It was predicted that 34% reducing sugar per gram of coir could be recovered when 32.8 mg/ml biomass was pretreated for 58 mins at 173 °C. The prediction was later experimentally verified.
