As the basic unit of educational reform, whether the curriculum can timely absorb relevant policy requirements and form advanced curriculum standards is an important part of practicing vocational education reform. Taking the core course “Food Quality and Safety Testing” of the Food Quality and Safety Major as an example, the article is based on the job position, strengthens ideological and political education, and establishes a three-dimensional training goal with the fundamental task of cultivating virtue. The course analyzes the standards of vocational qualification certificates and 1 + X certificates, incorporates “new technologies, new processes, and new standards,” and reconstructs the course content, which includes 6 projects and 20 tasks. Under the dual design of course ideological and political education and “Internet + Vocational Education,” a “dual-line, ten-link virtual and actual joint progress” course implementation model has been formed. Through continuous exploration and practice, the “Food Quality and Safety Testing” course has been updated and improved in terms of course objectives, content and requirements, and course implementation to effectively promote the implementation of new vocational education policies.展开更多
