abstract:
The influence of extrusion-cooking process parameters on changes in physical properties of potato starch was investigated. The process is characterized by small energy consumption. Expansion index decreased with raw material moisture content increase. It was found that extrusion-cooking process increases water absorption and solubility of starch. The highest value of Water Absorption Index was 569 % and Water Solubility Index was 40%.
