Plant Polyphenol Nanoparticle's Preparation and Application

Plant polyphenols are important secondary metabolites in plants. They have strong antioxidant activity, which has a certain effect on the prevention of cardiovascular diseases and other chronic diseases, and can be widely used as antioxidants in food, drugs, and many other fields. The use of nanotechnology to make polyphenolic compounds into nanoparticles can effectively protect polyphenols from destruction, and improve the antioxidant and stability of polyphenols. In this chapter, the preparation technology and functional characteristics of polyphenol nanoparticles are discussed in detail, and the preparation and application of polyphenol nanoparticles are provided with references.
