Advance in Bioactivities of Pectin and Its Application in Packaging Materials

Pectin is a biopolymer with good regenerative properties, gelibility and biocompatibility, and is increasingly widely used in food, medicine and other fields. This paper reviews the biological activities of pectin, such as antioxidant, antibacterial, anti-inflammatory and immune regulation, anti-glycation, anti-coagulation, etc., and introduces the research progress of biodegradable food packaging materials prepared by the combination of pectin with other natural polymer materials, nanometer materials and biological active agents, finally, it is pointed out that the study of the relationship between the molecular structure and bioactivity of pectin and its derivatives will contribute to the development and application of pectin in related fields, and the optimization of the performance and processing technology of pectin-based packaging materials is essential for their industrial production.
