The migration of gasses and liquids through (bio) polymers plays an important role in numerous applications and processes like, e.g., drying and (re)wetting of foods and food ingredients, packaging, and controlled release. A good understanding of the transport mechanisms is therefore of great importance to control these processes. The transport of solvents through (bio) polymers is a complex process and involves diffusion due to water concentration gradients, swelling, shrinkage, and relaxation of the polymeric matrix. Often also transitions between the glassy, rubbery, and/or viscous states of the polymer system are involved. Here we report on a theoretical and experimental study of water transport in biopolymer films of starch and gluten.
