1. Barrier Plastics, Processing of Wheat Gluten and A New Method to Measure Permeability
Sammanfattning : One way to extend the shelf life for foodstuff is to usemodified atmosphere packaging (MAP). It is important that MAPare gas tight or in some rare cases permselective to preservethe right gas mix. LÄS MER
2. Processing and Development of Wheat Gluten Plastics
Sammanfattning : Renewable packaging materials are of interest for a more sustainable environment. Wheat gluten is one of the most interesting candidates to replace petroleum-based oxygen-barrier polymers for packaging applications. LÄS MER
3. Effects of plasticizing and crosslinking on coatings based on blends of starch-PVOH and starch-lignin
Sammanfattning : A barrier material is usually needed on a fiber-based food package to protect the packed food from gases and moisture and thus maintain its quality. Barrier materials presently used in food packaging applications are mostly petroleum-based polymers. LÄS MER
4. Effects of plasticizing and crosslinking on the mechanical and barrier properties of coatings based on blends of starch and poly(vinyl alcohol)
Sammanfattning : In the last decades, intensive research has been carried out in order to replace oil-based polymers with bio-based polymers due to growing environmental concerns. So far, most of the barrier materials used in food packaging are petroleum-based materials. LÄS MER
5. Vacuum Dewatering of Cellulosic Materials : New insights into transport phenomena in the papermaking process
Sammanfattning : Working towards sustainable development within the forest industry, the dewatering of pulp and paper must be fully understood along with the dewatering of other cellulose-based materials. Huge amounts of energy are used during paper manufacturing so there is a potential for making the processes more energy-efficient. LÄS MER
