We first studied the model systems with single amylose or dextran
chain to establish references for comparison. In these systems,
the single polysaccharide chain and the surface are completely
covered in water and there exist many water molecules sufficiently
away from the polysaccharide chain to behave very similarly to
those in bulk conditions. Such reference systems can also be considered
to effectively present very large pores that result from very
low densities of food macromolecules. The energetics of water
