-
The waste apple pomace was treated by cellulase to produce glucose. The results show that the optimum operating conditions are:at 50℃, pH=5, keep the concentration of cellulase to 20 μg/g medium, react time to 12 h and do not treat the apple pomace with alkali. In the range of the reacting time we adopted, the influence of the cellulose concentration can be ignored. The producing technique of the citric acid and the determine method of the citric acid also been studied by experiments.
