Abstract
Abstract Effects of electron‐beam irradiation (0, 1.0, 2.7, and 4.4 kGy) on physicochemical properties, MW distribution as well as microstructure of starches separated from electron‐beam irradiated and stored wheats were investigated by differential scanning calorimeter (DSC), SEM, and static multi‐angle laser light scattering (MALLS). The profiles of starch viscosity illustrated that peak, hot paste, cold paste, and setback were considerably decreased with increasing irradiation dose. The DSC pattern indicated that the electron‐beam irradiation caused a slight decrease in gelatinization temperature. SEM results showed that on the surfaces of a few starch granules fissures appeared and that they become rough when the irradiation doses reached 4.4 kGy. Damaged starch (DS) contents analysis suggested that the DS increased from 5.33 to 7.38% as the dose increased from 0 (control) to 4.4 kGy. HPSEC measurement showed that the starch molecule were gradually degraded due to the electron‐beam irradiation treatment, and the molar mass of wheat starches decreased by one order of magnitude when the irradiation doses reached 4.4 kGy.
