1. Interactions between surfactants and starch : from starch granules to amylose solutions
Abstract : Starch is a mixture of two polysaccharides, amylose (AM) and amylopectin, which occurs naturally in the form of microscopic granules that are abundantly found in tubers, roots, cereal grains and fruits. In order to bring out their functional properties as thickeners and texture enhancers, starch granules are often disrupted by heating in excess water. READ MORE

2. Novel potato starch : new structure and beneficial qualities
Abstract : This thesis presents a simplified method for determining the internal molecular structure of whole starch without prior amylopectin isolation. The structure of potato and barley whole starches, the thermal properties of starch from potato lines with different genetic backgrounds and the relationship between molecular structure and functional properties of starch were examined in the thesis.

3. Starch in Processed Potatoes -Influence of Tuber Structure, Thermal Treatments and Amylose/Amylopectin Ratio
Abstract : 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. READ MORE

4. Barley starch : molecular structure and properties
Abstract : This thesis examined barley amylopectin structure and looked for correlations between the structure and physical properties of starch. The structure of amylopectin and gelatinisation and retrogradation of starch were studied in 10 different barley cultivars/breeding lines with differing genetic background. READ MORE

5. Multi-scale characterisation of pasta - Effects of raw materials on water absorption, water distribution, and microstructure
Abstract : Pasta is a product with a long history, but is also still being developed today. Producers want to use new raw materials to make pasta more nutritious, less allergenic, and less dependent on durum wheat. All have in common that new raw materials shall not compromise the desired texture properties of cooked pasta such as the “al dente” feeling. READ MORE
