2. 1. Foam Formation and Starch Gelatinization with Alpha-Crystalline Emulsifiers

   Author : Gisela Richardson; Livsmedelsteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Food and drink technology; Livsmedelsteknik; image analysis.; rheology; microscopy; amylose-lipid complex; gelatinization; dynamical arrest; amylose; starch; sponge cake; foam; emulsifier; alpha-gel; physical state;

   Abstract : In the baking industry, emulsifiers in the alpha-gel state are used for foam formation. This thesis focuses on some parts of the effects of the emulsifier: how the foam formation and foam stability are influenced by the physical state of the emulsifier, how emulsifiers change the gelatinization and gel formation of starch, and the impact that these factors may have in a true product such as a sponge cake.

4. 2. Retrogradation Properties of Starch

   Author : José Silverio; Livsmedelsteknik; []
   Keywords : 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;

   Abstract : 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.

5. 3. Starch stabilized Pickering emulsions : Colloidal starch particles and their effects on emulsion properties

   Author : Hisfazilah Saari; Avdelningen för livsmedel och läkemedel; []
   Keywords : Starch granules; Pickering emulsions; colloidal particles; sedimentation; acid hydrolysis; cold gelatinization; dissolution; non-solvent precipitation; nanoparticles;

   Abstract : Particles can be used to stabilize multi-phase systems known as Pickering emulsions. The aim of this thesis was to investigate how starch particles affect emulsion properties. Starch granules were used individually as well as in binary mixtures. READ MORE

6. 4. Processing and Properties of Expanded Starch Materials

   Author : Mia Sjöqvist; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; amylopectin; extrusion; starch; porosity; foams; moisture content; amylose; microwave treatment; absorption;

   Abstract : The need to strive towards a more sustainable development of the society is becoming increasingly urgent. As the population of the world is growing so is society´s impact on the environment. This is causing environmental problems with growing amounts of waste. READ MORE

7. 5. The Challenges of Analyzing the Molecular Properties of Starch

   Author : Daysi Pérez; Livsmedelsteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Amaranthus caudatus; Chenopodium quinoa; Chenopodium pallidicaule; Canna indica; Lepidium meyenii; Xanthosoma sagittifolium; Manihot esculenta; starch; amylose; amylopectin; field-flow fractionation; size distribution; dissolution;

   Abstract : Both the nutritional and functional properties of starch are directly influenced by the molecular structure of its polymers: amylose and amylopectin. It is therefore important to have reproducible methods for quantifying the molecular size. READ MORE
