N2 - The superior effects of addition of activated carbon were evidenced for microwave assisted hydrolysis of starches in cassava pulp and tapioca flour under hydrothermal conditions varying irradiation temperature (160-230 °C at 5 min), duration of heating time (5-18 min at 210 °C) and amount of activated carbon at 0.5-2.0:1:20 of activated carbon:solid:liquid ratio. The presence of 1.0 g/g in microwave-assisted hydrolysis gave much improved glucose yields (44.49% for cassava pulp and 71.93% for tapioca flour) at lower heating temperature (220 °C and 200 °C, each for 5 min) with suppressed formation of secondary decomposed compounds than those without addition of activated carbon (32.41% in cassava pulp at 230 °C and 55.11% in tapioca flour at 240 °C, each for 5 min). The highest glucose yield from cassava pulp (52.27%) was obtained after heating at 210 °C for 15 min.
