Research Progress in Encapsulation of Bioactive Compounds in Protein-Polysaccharide Non-covalent and Covalent Complexes
Bioactive ingredients such as polyphenols and carotenoids have various health benefits such as anti-cancer and antioxidant activities.However,bioactive components are unstable and easily damaged in the gastrointestinal environment,making them unable to fully exert their functional effects.Proteins and polysaccharides can form complexes via non-covalent or covalent interactions,which have been widely used as encapsulation materials to enhance the stability and activity of bioactive compounds.This review summarizes the types of protein-polysaccharide complexes,and describes the application of the anti-solvent,pH-driven,thermal gelation and emulsification methods for the delivery of bioactive ingredients by protein-polysaccharide complexes.It is anticipated that this review will provide a reference for the research and application of bioactive compounds encapsulated in protein-polysaccharide complexes.
