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...
