Perfume separation and analysis is one of the core practical courses of the perfume and aroma technology and engineering specialties, which is of great significance in cultivating students’ innovative thinking and application abilities. The paper analyzes the existing problem in the digitalization construction of the perfume separation and analysis course, and gives some reform strategy about curriculum objectives and contents reconstruction, integration of ideological and political education, teacher quality improvement, curriculum digital resource construction, intelligent teaching mode and assessment evaluation, in order to provide reference for the construction of aromatic professional courses and the cultivation of high-quality applied talents under the background of educational digital transformation.展开更多
