Biopolymers consist of monomeric units that are covalently bonded to form larger molecules. A strong link between the microstructure and rheology of the systems is observed. Because the glass transition temperature is itself a function of water content and sugar content, the rate of retrogradation, G, will also depend on the system composition, increasing with increasing water content because of the reduction in Tg.
