Effect of Acid-Base Pretreatment on Reducing Sugar Production by Wild Glutinous Rice

As a lignocellulosic biomass, wild colocasia can be efficiently hydrolyzed into reducing sugar after a certain degree of pretreatment. It is a high-quality raw material for the development and utilization of biomass energy such as fuel ethanol. The three factors of concentration, temperature, time, and solid-liquid ratio were selected as the three-level orthogonal experiment. The effects of acid-base pretreatment on the reduction of sugar in the wild carp were studied. The cell wall of the wild carp was treated by electron microscopy before and after pretreatment. The change. The experimental results show that the cell wall of the wild colocasia is thinner, the pores become larger, and the contact area is increased. The effect of acid pretreatment on the reduction of sugar by the wild colocasia is better than that of alkali pretreatment. When the acid concentration is 0.5% and the temperature is 100°C and solid-liquid ratio is 1:40, and the treatment time is 90min, the concentration of reducing sugar produced is up to 67.32mg/g.
