Dynamic Rheological Properties

Parallel plate configuration was used for the dynamic rheological analysis of ice cream samples. Initially, the amplitude sweep test was performed between 0.1% and 100% strain to determine the linear viscoelastic region, and according to the result, the frequency sweep test was studied in the frequency range of 0.1–10 Hz and angular velocity of 0.1–64 s<sup>−</sup><sup>1</sup> (ω). Elastic modulus ( *G*) and viscose modulus ( *G*) corresponding to angular velocity and frequency values were determined. The parameters for dynamic rheological properties were found using the power law model and nonlinear regression;

$$G' = \mathbb{K}'(\omega)^{\mathfrak{n}'} \tag{2}$$

$$G'' = \mathcal{K}''(\omega)^{\mathfrak{n}''} \tag{3}$$

In Equations (2) and (3), the *G* value represents storage modulus (Pa), *G* value loss modulus (Pa), ωangular velocity value (s−1), *K* , *K* consistency coefficient values (Pasn) and *n* , *n* flow behavior index values.
