The fabrication of chitosan/MOF smart packaging composite film and its application for simultaneous freshness preservation and monitoring of yak meat

Key Points

• Enhanced freshness preservation was achieved with a composite film made from chitosan and metal-organic frameworks (MOFs).
• Incorporating MOFs into the chitosan film improved the film’s barrier properties and freshness monitoring capabilities.
• The analysis focused on yak meat, showing positive results for its shelf life under controlled conditions.
• This approach suggests promising applications of smart packaging in meat preservation, highlighting potential commercial viability.
