'Sugar-glass' film uses viruses to kill harmful bacteria in food
Bacteriophages, also known as "phages," are viruses that infect and kill bacteria. Unlike antibiotics, which act like sledgehammers, wiping out all bacteria, phages specifically target single strains of these germs, leaving beneficial microbes unharmed. For example, phages are useful for selectively decontaminating cheese -- a food that relies heavily on the presence of beneficial bacteria for its flavor. Because phages are naturally found on fruits and vegetables and do not affect the odor, taste, safety or appearance of foods, scientists are investigating whether these "bacteria-eaters" could have an expanded role in promoting food safety.
But incorporating phages into food packaging has been challenging. Drying them out so they can be added to various types of films can kill the viruses. Other methods for stabilizing phages are also problematic, requiring special handling or equipment.
