aMean values of three replicate measurements; values sharing the same lowercase letters within a column are not significantly different at p < 0.05
b T o, T p, and T c indicate gelatinization onset, peak, and completion temperatures, respectively; ΔH refers to gelatinization enthalpy
cNot detected
dCOV, LPaG1-2, and LPbG1-2 indicate the granular starch citrates prepared through the dry heat and microwave-discharged cold plasma treatments, respectively. The detailed reaction conditions for granular starch citrates are depicted in Table 1
