It’s always frustrating to keep our food fresh. That’s why we often end up buying instant packaged food or order something from the nearby restaurant. But now, keeping food fresh is no longer a problem, all thanks to the transparent clay-based film invented by Sabanci University researchers.
A study led by Dr. Hayriye Unal discovers a new packaging film made from polyethylene and clay mixture that can maintain a friendly condition for food so it will stay fresh for days. This film is different from any food packaging solution that other scientists have invented. And if you’re wondering if this clay-based film can really hold food freshness pretty well, just see it yourself.
Tomato on the left side is wrapped by ordinary plastic and the right one is wrapped by clay-based film. For testing purpose, both tomatoes were left for 6 days in room temperature. And as you can see, the one wrapped with clay-based film stayed fresh, unlike the other one which went bad already. Wow!
But, how does it work actually?
As Dr. Unal said, three major aspects that affect food to go bad are bacterial contamination, water-oxygen permeability, and high concentrate of ethylene around food. Firstly, the researchers started by using polyethylene film. Then they incorporated clay halloysite nanotubes that could prevent those three major aspects from happening.
Wow. Looks like we don’t even need refrigerator anymore to keep our food fresh.
