Abstract
Plant polyphenols, secondary metabolites in plants, possess valuable functional properties, including anti-inflammatory, antioxidative, and hypoglycemic effects. However, their application in food products is often limited by chemical instability. This review examines innovative composite delivery systems designed to enhance the stability and bioavailability of plant polyphenols. In this article, we provide the current knowledge on the impact of these systems on polyphenol efficacy and discuss emerging sustainable methods for their preparation. The purpose of this review is to advance a summary of the understanding and application of plant polyphenol delivery in food science, promoting robust and environmentally friendly solutions.
