Interactions between cell wall polysaccharides and polyphenols: Effect of molecular internal structure

Area of Science:

• Food Science and Nutrition
• Plant Biochemistry
• Microbiome Research

Background:

• Cell wall polysaccharides (CPSs) and polyphenols are major components of dietary fiber in plant foods.
• Their bioefficacy and digestion by gut microbiota are influenced by structure, quantity, and intermolecular interactions.
• Food processing and dietary source significantly alter CPS and polyphenol composition and structure.

Purpose of the Study:

• To review the internal factors governing CPS-polyphenol interactions.
• To describe how molecular composition and structure mediate these interactions.
• To introduce analytical methods and underlying mechanisms of CPS-polyphenol interactions.

Main Methods:

• Literature review of current research on CPS-polyphenol interactions.
• Analysis of factors influencing interactions, including physicochemical properties.
• Summary of analytical techniques for studying these interactions.

Main Results:

• CPS-polyphenol interactions are driven by physicochemical properties: morphology, chemical composition, and molecular architecture.
• Key properties include surface area, porosity, sugar ratio, solubility, molecular weight, and functional groups.
• Understanding these interactions is crucial for predicting food processing effects and bioavailability.

Conclusions:

• Improved understanding of CPS-polyphenol interactions can bridge food processing and health outcomes.
• This knowledge can guide the development of healthier, more nutritious foods.
• Optimizing these interactions enhances the bioavailability of beneficial compounds like antioxidants and fermentation products.
