Acid Hydrolysis and Utilization of Distillers' Grains

Abstract:

Distillers' grains (DG) has high cellulose contents and is suitable for conversion to reducing sugar under dilute acid conditions. The effects of the hydrolysis conditions, including acid concentration, solid to liquid ratio, reaction temperature and time, were discussed, as well as the changes of microstructure and groups after hydrolysis. The conversion rate of reducing sugar could reach 25.07% (g/100g DG) when the hydrolysis conditions are as follows: the concentration of sulphuric acid is 5% (wt), the temperature is 120 °C, the ratio of sulphuric acid solution volume (mL) to weight of DG (g) is 30:1 and the reaction time is 10 h.
