Phase behaviour of gelatin/polydextrose mixtures at high levels of solids

► We presented the molecular interactions, phase behaviour and glass transition properties of gelatin/polydextrose mixtures. ► Applied treatment of the mixtures can confirm that gelatin retain or enhance structural cohesion and thermal stability. ► Condensed preparations of gelatin/polydextrose are amenable to transform in the rubber-to-glass. ► There were no direct, chemical interactions between the two constituents in the mixture.
