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

    Author : Soheil Saadatmand; Ulrica Edlund; Youssef Habibi; KTH; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; 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.

    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

    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

  4. 4. Wood hydrolysate Barriers

    Author : Anas Ibn Yaich; Ulrica Edlund; Ann-Christine Albertsson; Margaretha. Söderqvist-Lindblad; Inger Odnevall-Wallinder; KTH; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; 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
