PHYSICO-CHEMICAL PROPERTIES OF OXIDISED STARCHES OF DIFFERENT ORIGIN.

The native starches of potato, wheat, tapioca, corn and waxy corn were oxidised with sodium chlorite (III) in the presence of formaldehyde. The initial and modified starches were examined for the content of carbonyl and carboxyl groups, phosphorus, and amylose, and for reduction capacity, water absorption, solubility in water, and pasting characteristics. The results showed that the process of starch oxidation caused the changes in some physico-chemical properties of the modified starch preparations. Wheat starch was the most susceptible to oxidation with sodium chlorite (III) in the presence of formaldehyde, whereas waxy corn starch was the most resistant to the oxidation. The oxidised starches had lower content of total phosphorus and higher reduction capacity. The preparations of oxidised starches had lower maximum viscosity than initial starches.

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.
