在 40.0 至 140.0°C 的温度范围内，对含有 0%、10% 和 15%（w/w）蔗糖的混合物评估了制备的玉米和马铃薯淀粉膜的动态机械性能。获得了淀粉膜的储能模量（G′）、损耗模量（G”）和损耗因子（tanδ）的光谱。随着蔗糖含量的增加，观察到玉米和马铃薯淀粉膜的玻璃化转变温度显着降低。分别在两天和七天后第二次和第三次测量储能模量（G'）、损耗模量（G''）和损耗因子（tanδ）的光谱。储存2天后，损耗因子(tanδ)在59.81±1.86℃和95.96±1.67℃处出现峰值，但7天后仅在85.46±5.50℃处出现一个峰值。 7 天后观察到损耗因子有从较高温度到较低温度的转变趋势。
The dynamic mechanical properties of prepared maize and potato starch films were evaluated for mixtures containing 0%, 10% and 15% (w/w) of sucrose at temperatures ranging from 40.0 to 140.0°C. The spectra of storage modulus (G′), loss modulus (G″), and loss factor (tanδ) of starch films were acquired. Remarkable reduction in the glass transition temperature of maize and potato starch films was observed with the increasing sucrose content. The spectra of storage modulus (G′), loss modulus (G″), and loss factor (tanδ) were measured for the second and third time after two and seven days, respectively. The peaks of loss factor (tanδ) appeared at 59.81±1.86°C and 95.96±1.67°C after two-day-storage, but only one peak appeared at 85.46±5.50°C after seven days. A shifting trend from higher to lower temperature for loss factor was observed after seven days.
