1. 21. 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

3. 22. Starch in Processed Potatoes -Influence of Tuber Structure, Thermal Treatments and Amylose/Amylopectin Ratio

   Författare :Malin Sjöö; Livsmedelsteknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Livsmedelsteknik; Food and drink technology; Teknik; Technological sciences; microscopy; differential scanning calorimetry; amylopectin; amylose; starch; Solanum tuberosum; potato;

   Sammanfattning : The potato is one of our most important food crops, being sold in its natural state or processed into a wide range of products. Starch, by far the most abundant component in the tuber, is greatly affected by heat processing. LÄS MER

4. 23. Cross-linking and surface properties of EHEC and Starch -a QCM-D study

   Författare :Jesper Hedin; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Hydrogel; GMA; HM-EHEC; Starch; vicoelastic properties; Imidazole; QCM-D; SPR; EHEC;

   Sammanfattning : The increase of the green house gases and the crude oil price has resulted in a willingness to change the raw material in many industries from petroleum-based polymers to natural polymers. One such natural polymer is starch. Today, starch is used in the glue industry in wallpaper pastes. LÄS MER

5. 24. From Starch to Starch Microspheres. Formation of an Ordered Structure during Processing

   Författare :Lidia Elfstrand; Livsmedelsteknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Teknik; Pharmaceutical and related technologies; Läkemedelsteknik och relaterad teknik; crystallization; Technological sciences; starch microspheres; protein delivery;

   Sammanfattning : Starch microsphere is a dosage form suitable for the encapsulation of protein drugs. The starch microspheres investigated in this thesis are intended for release of the drug in a pre-designed way, or in controlled manner. LÄS MER

7. 25. 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.
