Abstract :The study aims to optimise microwave (MW) pretreatment of peach pulp wastes to obtain fermentable sugar for producing valuable products like acetone, ethanol and organic acids by fermentation. The Box-Behnken response surface experimental design method was employed for the optimization of MW hydrolysis process parameters. pH (2.0-5.5), particle diameter (180-250 µm) and peach pulp concentration (20-40 g/L) were the independent variables for total sugar concentration (TSC) considered in the study. Statistical analysis of variance (ANOVA) resulted in particle diameter and peach pulp concentration as the only significant variable among the studied independent variables. Product maximization (TSC) was achieved at pH= 5.50, particle diameter= 246.9 µm and peach pulp concentration= 39.5 g/L resulting in TS= 24.3 g/L with a hydrolysis yield of 61% (w/w).
