Microencapsulation allows the obtaining of hydrogels capable of protecting and maintaining the stability of bioactive agents in adverse conditions. However, the structure of the hydrogel presents permeability, which can affect the functionality of the microencapsulated bioactive material, therefore, the coating with proteins is a widely used solution. On the other hand, bovine blood (SB) and egg white (CH) are protein sources that have not yet been used as a coating material for hydrogels. In this study, we produced pectin hydrogels (HPEC) and alginate (HALG) coated with SB and CH proteins at different concentrations (2, 4, 8, 10%). Which were characterized in terms of protein adsorption, humidity, ash, morphology and average size. Subsequently, the hydrogels with protein coating of higher concentration (10%) were exposed to gastrointestinal conditions in vitro, and evaluated in terms of physical resistance and protein solubility. It was observed that the adsorbed amount of proteins was significantly higher in HPEC (p <0.05) compared to HALG, regardless of the type and concentration of protein used. Likewise, the increase in protein concentration in solution resulted in higher protein adsorption regardless of the type of hydrogel used. The structures of coated HPEC yielded at the end of the gastrointestinal simulation, whereas, coated HALG showed resistance. In parallel, protein solubility values exceeded 80% when the coated hydrogels were exposed to intestinal conditions. The results show that it is possible to use bovine blood and egg white as hydrogel coating material, achieving the expected effects, in terms of adsorption, resistance and solubility in specific environments. So, the use of this technology has great potential for future uses in the food and pharmaceutical industry.
