Abstract: As a conventional teaching method, Case Based Learning (CBL) has certain discipline limitations and has achieved good teaching results in medical education. For the knowledge system of food science and engineering majors, it is easy to have an impact on the establishment of students' knowledge system by completely copying CBL teaching method. This paper further designed and improved the CBL teaching method for biochemistry, the core course of food science and engineering major, and integrated the CBL teaching method with curriculum ideology and politics through practice, and achieved good results in the process of improving the teaching effect, students' academic performance and teaching effect. Through the multi-dimensional evaluation system in teaching introduction, teaching process, application transfer and other aspects of the investigation, combined with OBE engineering education evaluation system to improve the teaching effect.
