Characterization and Modeling of the Viscoelastic Behavior of Hydrocolloid-Based Films Using Classical and Fractional Rheological Models

Hydrocolloid-based films are a good alternative in the development of biodegradable due to their properties, such as non-toxicity, functionality, and biodegradability, among others. In this work, based on hydrocolloids (gellan gum, carrageenan, guar gum) were formulated, evaluating dynamic rheological behavior creep recovery. Maxwell’s classical fractional models implemented describe its viscoelastic behavior, using Vortex Search Algorithm for estimation parameters. The hydrocolloid-based showed where storage modulus (G′) loss (G″) indicated greater elastic (G′>G″). Maxwell model with two spring-pots an optimal fit experimental data compliance (J) (Fmin<0.1 R2>0.98). This shows that excellent describing recovery films. These results show importance estimating parameters allow behaviors applications design active because they us understand from point view, which can contribute improvement products food coatings, packaging, or other containing biopolymers.
