Plant polysaccharides and food quality homogeneous,heterogeneous and phase separated systems

摘要

The functiona behavior of plant polysaccharides and carbohydrates n food materials is oftne influenced by their phase behavior and dynamics.Phase behaivor includes polysaccharide interactions with water,solutes,and other polymers.Dynamics includes motions of whole molecules as well as more localized motions.These,in turn,can affect mechanical behavior,rates of association/reaction and,hence,stability of the material.In this presentation,the underlying physical chemistry of this molecular behavior is examine and its relationship to functional behavior in homogeneous,heterogeneous,and phase-separated systems illustrated.
