作者： Xin Lü xiaoni zhang College of Food Science and Engineering Northwest A&F University College of Economics and Management Northwest A&F University

Because the people’s living standard is keep improving and food safety accidents occurred frequently in recent years, food quality and safety problem, which is one of the most important research field in food science, is increasingly focused on. The specialty of food quality and safety was established to meet the increasing requirements of professional talents. Molecular biology course is the basic course in food quality and safety specialty syllabus. Based on the introduction of the position, functions and problems of the molecular biology course in food quality and safety specialty, it is primarily suggested that the teaching content should be reasonably set and improved, the teaching method should be changed from chalk-and-talk to heuristic, participatory and constructivism teaching method as well as the exploration experiments should be added and redesigned in the course. Moreover, practical teaching should be supplemented and web-based interaction teaching should be fully used to supplement inadequate credit hours. Through the reforming measures, the molecular biology course can meet the requirement of career development for students majored in food quality and safety and most importantly make students know how to study and construct knowledge by themselves.
