Abstract: The knowledge of microbiology is an important component of the knowledge system for undergraduate students majoring in food science and engineering. It is a very important basic course for students to learn, understand and master the basic concepts and knowledge, basic principles and operation of microbiology. The epidemic caused by new coronavirus has forced the changement of offline classroom teaching to online web learning of undergraduate students. This not only brings great challenges to the traditional teaching methods which rely on the teacher-student face-to-face teaching and learning, but also proposes new requirements for the students' inherent classroom learning style. A very serious problem that should be faced by teachers is to ensure the quality of education under the situation of COVID-19 prevention in order to achieve the teaching goal of the curriculum. During the period of epidemic prevention, the course group carried out the practical exploration of teaching methods through three-dimensional teaching material design, flipped classroom fine teaching, teaching and learning transposition guidance based on several years of reform experience, and achieved good repercussions. Therefore, we summarize this paper to provide a reference for the teaching reform of microbiology course in food specialty.

Key words: Food microbiology, Novel coronavirus pneumonia epidemic situation, Educational reformation, Exploration and practice
