  2. 21. Chicory (Cichorium intybus L) as fibre source in pig diets : effects on digestibility, gut microbiota and performance

    Author : Emma Ivarsson; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Abstract : The aim of this thesis was to increase our understanding about chicory (forage and root) as fibre source for pigs, by studying the effects of diets with inclusion of chicory on digestibility, digestion site, performance, gut microbiota and environment. In total 62 pigs were used, including newly weaned and growing intact pigs and growing post valve t-caecum (PVTC)-cannulated pigs. READ MORE

  4. 22. Conversion of xylan into value-added products

    Author : Reza Faryar; Bioteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; xylooligosaccharides; biosurfactant; prebiotic; xylan-based film; Lactobacillus brevis;

    Abstract : Today’s high demand on finding sustainable energy sources, replacing petroleum-based products and the needfor healthier food alternatives have forced us to search for natural recoverable resources and explore their manyhidden applications. One such resource is xylan, which has gained much attention as possible raw material forvarious exploitations. READ MORE

  5. 23. Dietary fibre production from oat hulls

    Author : Eva Schmitz; Bioteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Oat hulls; Dietary fibre; Chemical composition; Bleaching; Pre-treatment; Enzyme synergy;

    Abstract : The current threats of climate change connected to the unsustainable consumption of fossil resources paired with an increasing world population demands the exploration of alternative raw materials for the production of food, fuel and specialty chemicals. Agricultural waste streams present suitable sources due to their availability in large quantities at low costs without competing with current food production. READ MORE

  6. 24. Regulation of bile acids by prebiotic food components : Studies in rat caecum and in serum of mice and humans

    Author : Tannaz Ghaffarzadegan; Avdelningen för livsmedel och läkemedel; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Bile acids; Dietary fibre; Fat; Pectin; Guar gum; Barley; Lingonberry; Turmeric; Short-chain fatty acids; Gut microbiota; Caecum; Serum; Rat; Mice; Humans; GC-FID; UHPLC-MS;

    Abstract : Bile acids (BA) are formed from cholesterol in the liver and, apart from being part of fat digestion, they also act as signalling molecules in several health-related physiological processes. BA composition is regulated by gut microbiota as well as dietary fibre (DF) and fat in the diet. READ MORE

  7. 25. Adsorption of xylans on cellulosic fibres -Influence of xylan composition on adsorption characteristics and kraft pulp properties

    Author : Tobias Köhnke; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Xylan; Hornification; Lignin-carbohydrate complexes; Cationization; Isolation; Softwood kraft pulp; Extraction; Adsorption;

    Abstract : Xylans are polysaccharides present in large amounts in cell walls of vascular plants. They possess an inherent affinity to cellulose and will thus adsorb irreversibly on cellulose surfaces. READ MORE
