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...

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.

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.
