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. Wheat Gluten -Based Materials and Composites: Extrusion, Casting and Antimicrobial Properties

   Författare :Hasan Türe; Mikael Hedenqvist; José-Maria Lagaron; KTH; []
   Nyckelord :wheat gluten; extrusion; urea; montmorillonite; sol-gel process; hybrid materials; casting; compression moulding; potassium sorbate; antifungal; plasticiser; thermal; mechanical and barrier properties.;

   Sammanfattning : The use of bio-based polymers as packaging materials has gained much attention due to increasing environmental concerns regarding non-biodegradable petroleum-derived plastics. Wheat gluten (WG) is a valuable renewable resource for the production of bio-based materials because of its low price, biodegradability, good film-forming properties and good gas barrier properties under dry conditions.

4. 8. Aging and heat-sealing properties of films based on wheat gluten

   Författare :Sung-Woo Cho; Mikael Hedenqvist; Minna Hakkarainen; Mikael Lindström; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; wheat gluten; aging; migration; opacity; heat sealability; shear strength; Polymer chemistry; Polymerkemi;

   Sammanfattning : Recently the research interest of the possibility of using wheat gluten (WG) as packaging material has greatly increased due to its combination of high gas barrier, attractive mechanical, film-forming and renewable properties. The source is also readily available and inexpensive on a worldwide basis. LÄS MER

5. 9. Chitosan and chitosan/wheat gluten blends : properties of extrudates, solid films and bio-foams

   Författare :Fei Chen; Mikael Hedenqvist; Eliane Espuche; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Sammanfattning : This thesis presents four different studis describing the characteristics and processing opportunities of two widely available biopolymers: chitosan and wheat gluten. The interest in these materials is mainly because they are bio-based and obtained as co- or by-products in the fuel and food sectorIn the first study, high solids content chitosan samples (60 wt.

7. 10. Strategies to improve the aging, barrier and mechanical properties of chitosan, whey and wheat gluten protein films

   Författare :Idoia Olabarrieta; Mikael Hedenqvist; Jose Maria Lagaron; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Chemistry; biodegradable polymers; chitosan; whey protein; wheat gluten; poly ε-caprolactone ; montmorillonite; food packaging; permeability; mechanical properties; aging; pH; solubility; migration; solution casting.; Kemi; Chemistry; Kemi;

   Sammanfattning : Chitosan, Whey Protein Isolate (WPI) and vital wheat gluten (WG) are three biomaterials that have quite promising properties for packaging purposes. They have good film forming properties and good gas barrier properties in dry conditions. LÄS MER
