There is interest in the use of biopolymers to replace plastics in packaging for reasons of biodegradability and that these are renewable resources [112]. Thermoplastic properties of wheat gluten have been studied by the application of DMA and DSC to gluten films. Strong, transparent and water-resistant films can be obtained by casting films from ethanol/acetic, acid/water solvents. Moreover, the water-vapour barrier properties could be improved by the incorporation of lipids. Similarly, the manipulation of the different fractions of gluten could also produce distinct characteristics. 

In a model flavour-release system, 2-octanone could be released from BSA-pectin complexes by a shift in pH [113]. This was due to BSA imfolding on the oppositely charged, rigid polysaccharide matrix at a pH below the isoelectric point of BSA. DSC was used to examine the effect of flavour binding on the conformational stability of the protein.
