“…Figure 5a shows the variation of the storage modulus (G ), loss modulus (G ), and tan δ in relation to the angular frequency for formulation sample studies. It can be seen that the elastic behavior for F1, F2, F3, and F4 samples were greater than the viscous behavior (G > G ) and no crossing points were observed in the angular frequency interval in the study, indicating typical solid viscoelasticity, which is consistent with that reported by González Cuello et al [46], where it was found that biofilms based on binary mixtures of gellan gum and concentrated whey protein had a viscoelastic solid behavior. The behavior of the modulus G for F1, F2, F3, and F4 is observed to increase and decrease by about the concentration of potassium and calcium ions, respectively, keeping constant the concentrations of carrageenan, gellan gum, and guar gum.…”

Gonzalez Cuello et al [46] reported similar results for films prepared from binary mixtures. lated to gel formation with greater cross-link formation [13,47,48]; that is, by decreasing the concentration of Carrageenan and potassium ions, the G decreases as well.…”

“…Initial Solution: The VSA works with the vector radius ( → r t where t is the iteration counter) that generates a hyperellipsoid in a d-dimensional space. To center the hyperellipsoid in the solution space, let us define its center as µ 0 , where: (46) and x min ∈ R d×1 and x max ∈ R d×1 are the minimum and maximum bounds of the solution variables x.…”

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

La presente revisión versa sobre el almidón (amilosa y amilopectina) que constituye una fuente de energía importante en la alimentación humana. Existen almidones de lenta digestión o resistentes que se han asociado a efectos benéficos en la salud humana y animal. Esta macromolécula es tan versátil que tiene diversas aplicaciones en la industria alimentaria ya sea en la producción de alimentos o como aditivo (espesante, espumante, hidrocoloide); además puede utilizarse en la industria textil por sus propiedades termoplásticas. Por ello, esta molécula es una fuente de energía fundamental y también representa una plataforma versátil para la obtención de diversos productos.

Active films developers are persistently looking for new alternatives to improve the gradual release of active compounds. However, currently, there is almost no information concerning the effect of the active principles and no thermal technology as the ultrasound on the rheological behavior of active films. In this work, the effect of aqueous extract of Schinopsis balansae, Gliricidia sepium and ultrasound treatment on the rheological behavior of edible film made from carrageenan is evaluated. The films were obtained employing the casting method and the rheological tests were performed in the viscoelastic zone and adjusted to the Kelvin-Voigt model. Although, all EF showed viscoelastic rheological behavior (G′ > G″), structural changes were appreciated. These changes were mainly appreciated on G' that is the solid component, while no effect was appreciated with liquid component (G'') reflecting degradation of the solid structure. These results can contribute to developing active edible film with better rheological properties.
