A new antimicrobial active packaging can reduce the growth of the potentially fatal bacteria Listeria monocytogenes (LM) on the surface of ready-to-eat (RTE) foods, a new study finds.
The pullulan film active packaging can cut or stop growth of LM on the surface of RTE food, scientists from the University of Pennsylvania said.
Sakacin A can migrate from the biopolymer into food and inhabit the pathogen over three weeks of refrigerated storage, the researchers said.
The process aims to reduce the risk from foodborne pathogens and extend the shelf-life of the food items.
The biofilm requires less antimicrobial and allows controlled migration of the molecule from the film to the food.
