Abstract
The influence of amylose content (AC) on gel texture, thermal, pasting, rheological and morphologic properties, short-range order, X-ray diffraction pattern, solubility and swelling power of starches from nine proso millet cultivars was investigated. The solubility, swelling power, conclusion gelatinization temperature (Tc), gelatinization temperature range (Tc-To), gelatinization enthalpy (ΔH) and cohesiveness showed a negative correlation to the AC of millet starch. Whereas the pasting temperature (PT), peak viscosity (PV), trough viscosity (TV), final viscosity (FV), setback value (SB), gel hardness, and chewiness showed a positive correlation to the AC of millet starch. The R1047/1022 values of starches ranged in 0.7−0.9, and all starches showed similar morphology features (irregular, polygonal, and spherical shape) and crystal type, which showed no correlation to the AC.
