Abstract
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.
