Can the food major be transferred to Chinese medicine?

You can't. When we talk about changing majors, it is relative and there are professional restrictions. If your previous major was related to medicine, you can switch to Chinese medicine. Whether you can switch to Chinese medicine depends on the arrangement of each school. Moreover, the food specialty and Chinese medicine have a great span, which is basically impossible to change. Moreover, if you want to change majors, you should learn this major well first, and there are two others who can learn the knowledge of the major you want to change and pass the exam. It's really difficult to change majors. And there are many restrictions, and changing majors can only be relevant.
