2. 1. Xyloglucan-based polymers and nanocomposites – modification, properties and barrier film applications

   Author : Joby Kochumalayil Jose; Lars Berglund; José M. Kenny; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; xyloglucan; packaging; oxygen barrier; nanocomposites;

   Abstract : Biopolymers from renewable resources are of interest for packaging applications as an alternative to conventional petroleum-based polymers. One of the major application areas for biopolymers is food packaging, where a candidate polymer should meet critical requirements such as mechanical and oxygen barrier performance, also in humid conditions.

4. 2. 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

   Abstract : Forest biomass is expected to play an increasingly important role in tomorrow´s global bio-economy as one of the main renewable sources of materials, chemicals and energy. In the framework of the biorefinery concept, the forestry industry is looking for new processes to utilize several fractions in the biomass (cellulose, hemicelluloses, lignin etc. READ MORE

6. 4. Hemicellulose as barrier material

   Author : Hartman Jonas; Ann-Christine Albertsson; Gunnar Henriksson; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Hemicellulose; galactoglucomannan; plasma surface treatment; vaporphase grafting; benzylation; contact angle; oxygen permeability; solution casting; Cellulose and paper engineering; Cellulosa- och pappersteknik;

   Abstract : Polysaccharides constitute an important source of raw materials for the packaging industry today. Polysaccharides have good natural barrier properties which are necessary for packaging films. Cellulose is the forerunner among renewable polymers for such applications. Hemicelluloses represent a new interesting breed of barrier materials. READ MORE

7. 5. Effects of Citric Acid on Starch-Based Barrier Coatings
