Abstract With the theme of “extraction of biomass orange peel pectin and process flow design”, focusing on the social hot issue of “utilization of biomass resources”, project-based teaching was carried out around key knowledge of high school chemistry, such as organic chemistry, experimental chemistry, process flow, and so on. Students were guided to complete activities such as organic structure and property analysis, experimental design and optimization, pectin extraction and process flow design, deepened the understanding of “structure determines property”, formed the general idea for material separation and purification, built the process flow thinking model, experienced the ways and significance of biomass resources utilization, and improved their core literacy in chemistry and problem-solving ability.
