1. 1. Retrogradation Properties of Starch

   Författare :José Silverio; Livsmedelsteknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; surfactants; lipids; degree of polymerization DP ; isothermal microcalorimetry; differential scanning calorimetry DSC ; crystallinity; amylose; amylopectin; gelatinization; starch; retrogradation; temperature cycling; PCA; Food and drink technology; Livsmedelsteknik;

   Sammanfattning : The main purpose of this thesis was to examine various factors influencing starch retrogradation. The reassociation events of starch, which are closely linked to the staling of bakery products, were mainly studied by thermal analysis. Some aspects of starch gelatinization are also included.

3. 2. 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. 3. Amylopectin - Interactions with Lipids and Proteins

   Författare :Henrik Lundqvist; Livsmedelsteknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; binding isotherm; isothermal titration calorimetry; differential scanning calorimetry; retrogradation; alpha-lactalbumin; beta-lactoglobulin; whey protein; surfactant; lipid; exterior chain length; barley; potato; starch; amylopectin; amylose; Food and drink technology; Livsmedelsteknik; Proteins; enzymology; Proteiner; enzymologi; Lipids; steroids; membranes; Lipider; steroider; mebran;

   Sammanfattning : Starch is a common ingredient in many products, influencing properties such as viscosity, stability, sensory properties and appearance. These properties and how they change with time in the process called retrogradation are dependent on the structure of starch and its interaction with other components such as lipids and proteins.

5. 4. 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

7. 5. Interactions between Amylose, Native Potato, Hydrophobically Modified Potato and High Amylopectin Potato Starches

   Författare :Fernando Ortega-Ojeda; Livsmedelsteknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Livsmedelsteknik; Food and drink technology; DSC; rheology; starch; polymers;

   Sammanfattning : The behaviour of different starches and their mixtures was investigated using several analysis techniques, i.e. small-deformation oscillatory measurements (rheological measurements), differential scanning calo-rimetry (DSC), light microscopy, and UV spectrophotometry (turbidi-metry).
