Natamycin and nisin supported on starch edible films for controlling mixed culture growth on model systems and Port Salut cheese

Consumer demand for natural food additives has increased and, as a consequence, the use of natural antimicrobials like natamycin and nisin is being investigated. In the case of cheese, surface colonization by microorganisms constitutes a significant risk to consumer's health. In this study, the...

In the case of cheese, surface colonization by microorganisms constitutes a significant risk to consumer's health. In this study, the effectiveness of natamycin and nisin supported in tapioca starch films against Saccharomyces cerevisiae and Listeria innocua in a mixed culture present on the surface of a model system and of Port Salut cheese was evaluated. It was observed that the preservatives incorporated in starch films, controlled growth of both microorganisms present together on the surface of the cheese during storage. Additionally, the joint presence of nisin and natamycin was effective as a barrier against a mixed culture preventing an external contamination of cheese and of a model system, during storage.
