A newly developed biodegradable chitosan (CS) and gallic acid (GA) conjugate fruit packaging could reduce food waste while improving sustainability and freshness, according to the latest university research. The CS-GA films developed by scientists at South Korea’s Chungnam National University are biodegradable, edible and offer elevated mechanical strength.“This investigation explored the utilization of chitosan, an abundant natural resource, for food packaging applications. The research methodology employed a limited array of chemical agents, with the coating process exclusively involving substances and water,” study lead professor Won Ho Park from Chungnam National University, tells Packaging Insights.
