2. 1. 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

4. 2. Wood Hydrolysate for Renewable Products

   Author : Yingzhi Zhu Ryberg; Ulrica Edlund; Ann-Christine Albertsson; Ann Cornell; Louise Staffas; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; wood hydrolysate; hemicellulose; oxygen permeability; PALS; film; coating; CMC; chitosan; HSP; Polymer chemistry; Polymerkemi;

   Abstract : Renewable biomass has been used by mankind for a long time for different purposes, from simply food to industrial products. Among a large family of polysaccharides, hemicellulose is non-edible but has shown a potential in many industrial fields such as medicine, agriculture and packaging. READ MORE

5. 3. Modification and Utilization of Wood Hydrolysates

   Author : Marie Svensson; Ann-Chrisitne Albertsson; Petra Mishnick; Ulf Gedde; KTH; []
   Keywords : wood hydrolysate; hemicellulose; microsphere; hydrogel;

   Abstract : Polysaccharides have been used for many years in a variety of products such as food, fuel supply and industrial products. During recent years there has been an increasing interest in a group of polysaccharides, hemicelluloses, due to their highly availability, renewability and potentially low price. READ MORE

6. 4. Bio-based barriers from wood hydrolysates : A pilot-scale approach

   Author : Soheil Saadatmand; Ulrica Edlund; Youssef Habibi; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Wood hydrolysate; biorefinery; oxygen permeability; multilayer barriers; food packaging.; vedhydrolysat; syrgaspermeabilitet; barriärskikt; livsmedelsförpackning;

   Abstract : Wood hydrolysates (WHs) are liquids extracted from the hydrothermal treatment of wood. They exist as the byproduct of forestry industries such as the dissolving pulp and fiberboard industries. WHs are hemicellulose-based with a large share of lignin in the chemical composition.

7. 5. 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
