Three key factors affecting total reducing sugars yield from sugarcane molasses hydrolysis, such as sulfuric acid concentration, hydrolysis temperature, hydrolysis time, were optimized by response surface method. Design Expert analysis indicated that 55.9±0.2 g total reducing sugars can be obtained from hydrolyzing 100 g original sugar molasses under the conditions of sugar molasses Brix 65, sulfuric acid concentration 4%, hydrolysis temperature 94℃ and hydrolysis time 66 min. The actual result was consistent with the predicted value.
