【 摘 要 】

The need for materials resistant to bacterial action has led to increases in biomaterials field research in food and pharmaceutical industry, particularly with regard to obtaining low cost materials. In this study, starch films easily obtained were used. The application is favorable to their application as biomaterials and studying the bactericidal activity againstSalmonella typhimurium ,Escherichia coliandStaphylococcus aureus . The results showed that the films were capable to release about 6 mmols of nitric oxide (NO) per gram of film and that they had potential antibacterial action againstS. typhimuriumandS. aureus , showing no significant results againstE. coli . These results indicate that nitric oxide has bactericidal action and the starch films containing eggshell membrane, collagen and albumin can be used as packaging materials in contact with food or compounds which must be preserved from the bacterial action. DOI: http://dx.doi.org/10.14685/rebrapa.v3i1.92
