A Rutgers University researcher and a team of Harvard scientists have developed a biodegradable, antimicrobial food packaging solution to replace plastic. The nontoxic, plastic-free food packaging solution is plant-based and is applied on foods as a spray. The packaging is effective in protecting food products from pathogens, spoilage, and physical damage.

The innovative, spray-applied food packaging material comprises biopolymer fibers that are laced with natural, antimicrobial ingredients. The antimicrobial ingredients—such as thyme oil, citric acid, and nisin—serve as sensors that can eliminate bacterial strains on food products.
