Abstrakt: In this study, an active films of polyvinyl alcohol (PVA) films, incorporated with sodium nitrite were developed, characterized and applied to pork stored for six days at 25 °C. As for the film characterization by FTIR, no chemical interactions were observed between nitrite and PVA under the studied conditions. The physical properties of the PVA films were not altered by the presence of nitrite. PVA films incorporated with 100 ppm nitrite reduced TBARS values of refrigerated pork from 0.63 µmol MDA/g (control) to 0.49 µmol MDA/g (PVA 01). Color changes were observed in all meat samples packaged with the film. It is concluded that the presence of nitrite does not interfere in the physical properties of the PVA films and that the developed films have an active potential for application in pork in natura.
