Polyphenol–Polysaccharide Complex: Preparation, Characterization, and Potential Utilization in Food and Health

Abstract

Polysaccharides and polyphenols coexist in many plant-based food products. Polyphenol–polysaccharide interactions may affect the physicochemical, functional, and physiological properties, such as digestibility, bioavailability, and stability, of plant-based foods. In this review, the interactions (physically or covalently linked) between the selected polysaccharides and polyphenols are summarized. The preparation and structural characterization of the polyphenol–polysaccharide conjugates, their structural–interaction relationships, and the effects of the interactions on functional and physiological properties of the polyphenol and polysaccharide molecules are reviewed. Moreover, potential applications of polyphenol–polysaccharide conjugates are discussed. This review aids in a comprehensive understanding of the synthetic strategy, beneficial bioactivity, and potential application of polyphenol–polysaccharide complexes. Expected final online publication date for the Annual Review of Food Science and Technology, Volume 13 is March 2022.

Physical properties and hypoglycaemic activity of biscuits as affected by the addition of stigma maydis extract

“…In addition, the interaction between polysaccharidepolyphenols in S.M. extract and starch could reduce the aggregation of starch (Guo et al, 2022). In the baking process, the high temperature made the starch molecules break and decreased the hardness of biscuits found that the hardness of biscuits decreased with the addition of four different oleogels; the effect of S.M.…”

Targeting mTOR Signaling by Dietary Polysaccharides in Cancer Prevention: Advances and Challenges

“…51 CPSs could interact with multiple polyphenols to modify several functions of polysaccharides. 52 Arabinoxylan (AX) and ferulic acid (FA) groups are often esterified with Arfa (arabinofuranosyl) residues. 53 It is reported that AX has the potential to prevent cancer, which may be related to FA.…”

“…Cell wall polysaccharides (CPSs) are non-starch polysaccharides and important sources of dietary fiber . CPSs could interact with multiple polyphenols to modify several functions of polysaccharides . Arabinoxylan (AX) and ferulic acid (FA) groups are often esterified with Arfa (arabinofuranosyl) residues .…”

Co-encapsulation of curcumin and resveratrol in zein-bovine serum albumin nanoparticles using a pH-driven method

“…5 In this case, the smaller surface of nanoparticles (NPs) exposes the encapsulated polyphenols to a lower level of environmental stress. 4,6 The sustained release profile helps in maintaining stable blood concentrations and reducing toxic side effects, 7 thereby improving the oral bioavailability and enhancing therapeutic effects. Among all the reported delivery vehicles used for poorly soluble nutraceuticals/drugs, prolamins have attracted a certain degree of interest from the scientific community due to their biodegradability, biocompatibility, and renewability.…”
