ABSTRACT

Polyphenols are a class of secondary metabolites of plants with biological activity, and are the most abundant biologically active components in fruits and vegetables. Apple polyphenols are the general term for polyphenols contained in apples. The content of apple polyphenols is affected by fruit maturity, cultivation methods, environmental conditions and storage conditions. Apple polyphenols are particularly rich in immature apples, and the polyphenol content of immature fruits is 10 times that of mature fruits. A large number of efficacy studies have shown that apple polyphenols have multiple biological functions such as antioxidant, antibacterial, and elimination of odor, anti-cancer, lowering blood pressure, and lowering blood sugar. At present, apple polyphenols have been widely used in medicine, food, daily chemicals and other fields. This article analysed and comprehensively summarized the composition, physical properties, preparation technology, biological function and application status of apple polyphenols, and provides ideas for the future development and utilization of apple polyphenol resources.
