  1. 1. Closed-loop strategy for valorization of starch : From starch to functionalized starch biomaterials and bioplastics

    Författare :Duo Wu; Minna Hakkarainen; Elisabetta Ranucci; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Starch; Nano-graphene oxide; Microwave; Valorization; Scaffold; Biomineralization; Bioplastics; Compatibilizer; Plasticizer; Fiber- och polymervetenskap; Fibre and Polymer Science;

    Sammanfattning : The desire to utilize renewable resources and avoid wastes drives us to develop new concepts for material design. Non-edible starch feedstocks and starch bioplastic wastes were previously considered useless. LÄS MER

  3. 2. Short-Chain Fatty Acid Starch Stabilized Pickering Emulsions : Design, Properties and Applications

    Författare :Nabilah Binti Abdul Hadi; Avdelningen för livsmedel och läkemedel; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Short-chain fatty acid starch; Physicochemical properties; Pickering emulsions; Starch modification; Emulsion stability; Starch hydrolysis; In vitro digestion; Lipolysis;

    Sammanfattning : Pickering emulsions are emulsions stabilized by solid particles. Particles with optimal dual wettability toward both of the oil and water phases, can be adsorbed onto the interface, thereby providing the stability of the emulsions. LÄS MER

  4. 3. Means to Optimize the Nutritional Properties of Starch in Potato Products - Impact on glycaemia, satiety and resistant starch content

    Författare :Margareta Leeman; Avdelningen för livsmedel och läkemedel; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Näringslära; amylopectin; starch; glycaemic index; resistant starch; Nutrition; vinegar; satiety; amylose; Solanum tuberosum; potato;

    Sammanfattning : Despite decreased consumption potatoes still constitute an important staple in the Swedish diet. An objection to potatoes and potato products from a nutritional point of view is the ease by which the starch is digested and absorbed in the gastrointestinal tract. LÄS MER

  5. 4. Crystallinity and Morphology of Starch Polymers in Films

    Författare :Åsa Rindlav Westling; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; morphology; amylose; surface; thermal transitions; amylopectin; starch; crystallinity; film;

    Sammanfattning : Starch is a renewable material that can be converted into biodegradable plastic products, or films with excellent oxygen barrier properties. Films of potato starch, amylose, amylopectin and blends thereof were made by solution casting. LÄS MER

  7. 5. Investigation of Modified Cellulose and Starch via Hydrolysis and Mass Spectrometry

    Författare :Arieh Cohen; Avdelningen för arbets- och miljömedicin; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; ESI-MS; Polysaccharides; Hydrolysis; Cellulases; Starch Hydrolases; Enzymatic Degradation; Enzymes; Substituent Distribution; Modified Cellulose; Mass Spectrometry; Modified Starch; Analytical chemistry; Analytisk kemi; HPAEC-PAD;

    Sammanfattning : Starches and celluloses can be chemically modified in order to affect their physiochemical properties. Modification of these carbohydrate polymers entails derivatising their free hydroxyl groups with functional groups. LÄS MER
