    Abstract : Food packaging should ensure the safety and quality of food, minimize spoilage and provide an easy way of storing and handling it. Barrier coatings are generally used to meet the demands placed on fibre-based food packages, as these have the ability to regulate the amount of gases that can enter them. READ MORE

  4. 9. Wood hydrolysates- New concepts in renewable material design

    Author : Yingzhi Zhu Ryberg; Ulrica Edlund; Ann-Christine Albertsson; Dufresne Alain; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; wood hydrolysate; oxygen barrier; coatings; films; hemicellulose; lignin; CMC; chitosan; HSP; PALS; spray drying; SEM with tensile test; glyoxal crosslinking.; vedhydrolysat; syrebarriäregenskaper; ytbeläggningar; filmer; hemicellulosa; lignin; CMC; kitosan; HSP; PALS; spraytorkning; SEM med dragprovning; glyoxal tvärbindning.;

    Abstract : Wood hydrolysates (WHs) are biomasses obtained in processes involving hydrothermal treatments of wood. WHs are rich in hemicelluloses and lignin. Instead of complicated extraction processes, such as precipitation, or extensive purification, this work utilizes the crude WHs. READ MORE

  5. 10. Wood hydrolysate Barriers

    Author : Anas Ibn Yaich; Ulrica Edlund; Ann-Christine Albertsson; Margaretha. Söderqvist-Lindblad; Inger Odnevall-Wallinder; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; wood hydrolysate; xylan; hemicellulose; layered silicates; oxygen barrier; packaging; film; coaing; birch.;

    Abstract : Wood hemicellulose is an abundant but fairly unexploited renewable feedstock. Recent studies have shown that hemicelluloses have a large potential for use in the food packaging industry as a sustainable alternative to the conventional oxygen-barrier materials used today. READ MORE
