To improve comprehensiveness, innovation and exploratory of chemistry experiments for teaching, an experiment "preparation of maltose syrup by starch catalytic hydrolysis" was designed. The amylase was prepared and applied as catalyst in the starch hydrolysis process. The reaction had enzyme-catalyzed characteristics, with optimal catalytic temperature 55 ℃. The experiment design featured agriculture and forestry university discipline. Not only did it integrate theoretical teaching with practice to help cultivate the students' scientific spirit, but also was a profound ideological and political course.
