EXTRUSION - COOKING OF POTATO STARCH AND SELECTED PROPERTIES OF THE EXTRUDATES

Using single- and twin-screw extrusion cookers samples of potato starch were processed at varying temperature profile in the barrels, and a various feed moisture content. All the expansion, density, shearing stress, characteristics of paste viscosity, water absorption index, water solubility index, glucose content, reaction with iodine, enthalpy of gelanisation, and resistance to the free radical decomposition at elevated temperature were determined for the extrudates. The product density in the twin-screw cooker increased with the moisture content. The higher temperature in the barrel and die also favoured the product density increase. The expansion ratio of the products depended on these parameters in an opposite manner. The single-screw extrusion cooking provided the product of higher density.

W latach 2022-2024 kwartalnik naukowy Polish Journal of Food and Nutrition Sciences realizuje projekt nr RCN/SP/0520/2021/1 finansowany ze środków budżetu państwa – Ministerstwo Edukacji i Nauki w ramach programu „Rozwój czasopism naukowych”. Dofinansowanie wynosi 120 000 zł. W ramach projektu podejmowane są działania zmierzające do podniesienia poziomu praktyk wydawniczych i edytorskich, zwiększenia wpływu czasopism na rozwój nauki oraz utrzymania się czasopism w międzynarodowym obiegu naukowym.

In the years 2022-2024, the scientific quarterly Polish Journal of Food and Nutrition Sciences accomplishes a project no. RCN/SP/0520/2021/1 financed from the state budged – Ministry of Education and Science Republic of Poland in the framework of a program “Development of scientific journals”. The financing amounts to 120,000 PLN. The program aims at improving the level of publishing and editing practices, increasing the impact of scientific journals on science development, and extending the international range of scientific journals.
