Anti-Microbial Biodegradable Food Packaging for Preventing Foodborne Illness
Using sustainable and biodegradable materials, researchers at UGA have developed a new food packaging which effectively inhibits the growth of bacteria known to cause foodborne illness.
As consumers demand more and fresher produce, anti-microbial packaging can help mitigate both the economic loss resulting from spoilage and illness resulting from the growth of microbes. Anti-microbial packaging can be used to maintain the safety, shelf life, and quality of perishable foods and is particularly applicable to the rapidly growing fresh produce industry, which has seen a large number of outbreaks of foodborne illness over the past two decades. The packaging also uses exclusively biodegradable materials, appealing to the growing market of environmentally-conscious consumers.
Existing anti-microbial food packaging works by spraying or dipping the packaging with the anti-microbial agents, but the anti-microbial activity is often lost due to inactivation by the food components. While other anti-microbial packaging films apply the anti-microbial agent all at once, this packaging uses a controlled release mechanism to release the antibacterial agent nitric oxide over time. Nitric oxide inhibits the growth of a wide range of bacteria, with its principal advantage being is efficacy against antibiotic-resistant strains. Integrating the anti-microbial agent with sustainable and biodegradable packaging also addresses the demand for environmental friendly solutions in the packaging industry by cutting down on waste.
The packaging takes the form of a film made with bio-materials interspersed with the nitric oxide anti-microbial agent. The film slowly releases the nitric oxide, so it effectively fights bacteria over a sustained period of time. Nitric oxide is used because it has demonstrated anti-bacterial effects and inhibits the growth of bacteria that cause food poisoning. Most importantly, it is effective even against the growing number of antibiotic-resistant strains of bacteria. Furthermore, the film is made of renewable bio-materials and is fully degradable, unlike traditional petroleum-based plastic packaging. The use of biodegradable materials together with the anti-microbial properties comprise a food packaging that is safe and eco-friendly, better preserving the quality shelf-life of food.
