  1. 6. Wheat Flour Dough-Rheological and Structural Aspects

    Författare :Helena Larsson; Livsmedelsteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; starch gel; gluten; water distribution; lipids; starch granule surface; starch content; mixing; ultracentrifugation; structure; rheological measurements; wheat flour dough; phase separation; ethyl hydroxyethyl cellulose; Food and drink technology; Livsmedelsteknik;

    Sammanfattning : The thesis presents a rheological study on wheat flour dough, in relation to the structural influence of the different dough constituents, added components and mixing time. Rheological investigations have been focused on measurements at small deformations, including dynamic oscillation and stress relaxation, although complementing measurements have been performed in large deformation viscosity experiments.

  3. 7. Staling and Starch Retrogradation in Speciality Bread

    Författare :Jeanette Purhagen; Livsmedelsteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Anti-staling agents; Staling; Starch retrogradation; Bread; Water content; Bran; Heat-treated additives; Gluten-free bread;

    Sammanfattning : Bread products are one of the most common and important foods in our daily diet, and have been since ancient times. Although it has a long history and comes in many variations, the staling phenomenon of bread is still not fully known. LÄS MER

  4. 8. 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

  5. 9. 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

  7. 10. Material Properties of Starch and Cereal Protein Films and Foams

    Författare :Thomas Gillgren; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; foam; avenin; oxygen permeability; amylopectin; water vapour permeability; plasticization; mechanical properties; zein; film; glass transition temperature; kafirin; prolamin; cereal protein; amylose; starch;

    Sammanfattning : Materials that are renewable and biodegradable are demanded for environmental reasons. Biopolymeric materials, such as materials from starch and cereal proteins, are both renewable and biodegradable. However, starch and cereal protein materials are generally rather brittle and therefore need to be plasticized to become more flexible. LÄS MER
