Sažetak
Wheat starch was treated with high-voltage electric discharge (HVED), Na2HPO4, Na5P3O10, and by combination of HVED with each chemical modification. Gelatinization properties (by DSC), swelling power and solubility were determined and images of starch granules were scanned by SEM. Results showed that HVED treatment did not influence gelatinization temperatures and enthalpy, but it did influence gelatinization temperatures of chemically modified starches, with more pronounced influence when used after chemical treatment. Swelling power (SP) and solubility (SOL) increased with increase of heating temperatures, with more pronounced effect of temperature on HVED treated starch in relation to native starch. Chemical modification increased SP and SOL, whereas HVED reduced SP and SOL of chemically modified starches. SEM analysis revealed physical damage of starch granules by HVED. HVED is promising tool in modification of starches, both individually and in combination with chemical modifications.
