The steady and dynamic shear rheological properties of currant paste samples as a function of storage temperature (15, 25 and 35 °C) and time (180 days) and plasticizers content (water and/or glycerol) have been evaluated. Apparent viscosity (η_a) has been found to be significantly increased with prolonged storage, implying possible structural changes, and decreased with the increase in storage temperature and the addition of water or/and glycerol. Flow behavior index and consistency index were determined by fitting the resulting experimental data to a power law equation with high values of correlation coefficients (R² ≥ 0.912). Furthermore, the combined effect of storage temperature, time and plasticizers concentration on the apparent viscosity was described adequately by a proposed empirical model, with low standard relative errors (SRE ≤ 0.011). Additionally, the viscoelastic properties were significantly affected by all evaluated parameters in the same way as in apparent viscosity while both moduli (G′ and G″) were modeled sufficiently (R² ≥ 0.884) as power functions of oscillatory frequency. The heat treatment (heating from 25 to 100 °C and cooling back with a rate of 10 °C/min) applied has proved sufficient to reverse the observed storage effects. Moreover, the modified Cox-Merz rule was satisfactorily applied to describe the correlation between the apparent viscosity and the complex viscosity.

评估了醋栗糊样品的稳态和动态剪切流变性质，其与储存温度（15、25和35℃）和时间（180天）以及增塑剂含量（水和/或甘油）的关系。表观粘度（η_一个）已被发现与长期储存地显著增加，这暗示可能的结构变化，以及与存储装置中温度的上升和添加水和/或甘油降低。通过将所得实验数据拟合到具有高相关系数值（R ² ≥0.912）。此外，通过建议的经验模型充分描述了存储温度，时间和增塑剂浓度对表观粘度的综合影响，且标准相对误差较低（SRE≤0.011）。此外，粘弹性性能显著影响以相同的方式评价所有参数，如表观粘度而两个模量（G'和G“）充分建模（R ²  ≥0.884）作为振荡频率的功率的功能。事实证明，进行热处理（从25到100°C加热并以10°C / min的速度冷却）可以逆转所观察到的存储效果。此外，满意地应用了改进的Cox-Merz规则来描述表观粘度和复数粘度之间的相关性。
