Polysaccharides such as gellan gum have been used in the alimentary industry in order to produce functional foods. The estimation of the activation energy of biopolymers materials provides important information for adequate selection and application of these materials, which are utilized in processes such as active film production. This study aims to determine the flow behavior and activation energy of film forming solution (FFS) based on carboxymethylcellulose (CMC) and xanthan gum (XG) formulated with various concentrations (0.1, 0.5 and 0.7 % p/v) of high acyl gellan (HAG). The flow behavior of the dispersions was determined at 25°C with a controlled stress rheometer (HAAKE MARS 60) whereas the activation energy values were established through modeling the relationship between viscosity and temperature employing the Arrhenius equation. All the studied FFS showed non-Newtonian shear-thinning behavior with an adequate 630 Ricardo Peña-Flórez et al. adjustment to the Ostwald de Waele model. With respect to the activation energy values, the highest concentration of HAG yielded, the highest activation energy values (37 to 48 kJ/mol); whereas dispersions without HAG showed the lowest activation energy values (1.27 kJ/mol). These findings indicated that activation energy is proportional to HAG concentration. These results are promising and suggest the possibility of developing heat resistant active films based on HAG.
