Increasing the shelf-life with innovative MOF packaging

“Metal-Organic Frameworks (MOFs) are hybrid materials with high porosity and tunable physical and chemical properties. Due to their properties, MOFs are utilized for different purposes in the food industry. Moreover, these materials display good biocompatibility and have not shown adverse reactions during testing. The incorporation of MOFs into packaging materials can provide antimicrobial properties. For

Natural sticker to make fruit last longer, in an effort to reduce food waste

In the US, over half of fresh fruit and vegetables go to waste. But a new invention claims to extend the shelf life of fresh fruit. A simple sticker can add an extra 14 days of freshness, says StixFresh. Using natural plant compounds, the sticker creates a protective layer, slowing the ripening process. The company

Antimicrobial Packaging on the Rise Again

Pathogens such as Campylobacter, Escherichia coli, Listeria monocytogenes, and Salmonella, as well as yeasts and molds, are major concerns and often define food shelf life. Antimicrobial packaging can be used to control microbial growth in packaged food, and given consumer interest in food with fewer preservatives, interest in its use is growing. Antimicrobial packaging is the deliberate incorporation
