Abstract: The food preservation curriculum group, mainly including introduction to food preservation, food freshness maintenance and food preservation, and other courses, covers two important food preservation technologies, food processing and food preservation, which is strong cross-cutting and comprehensive. The teaching of food preservation technology at Zhejiang University is carried out in the form of a curriculum group, which is an important part of the education of undergraduates majoring in food science and engineering. The teaching team innovatively proposes a double helix teaching organization model based on Bruner’s spiral cognitive theory. The teaching reform has effectively realized the organic integration of the courses in the course group, improved the quality of the food preservation course group, and will create a new way of teaching reform for the food course group.
