People around the world have been trying to preserve fruits, vegetables and meat since ancient times.
Food preservation has always been important from traditional pickling or fermentation methods to more modern plastic film Canning, freezing or packaging methods.
\"Food packaging that can interact with food can help to be safe and prevent economic losses from deteriorating,\" said Hayriye Unal of Sabanci University in Turkey . \".
\"Professional films that are able to preserve a variety of foods are very popular,\" Unal said . \".
According to USDA data, about 30 to 40 of the food produced by farmers in the country will be wasted, the researchers said.
Over the past 20 years, scientists have been developing alternative ways to preserve food and have focused extensively on packaging.
\"While the company has been able to make many films that prevent dried fruits and vegetables, adding additional features to the same film is a challenge,\" Unal said . \".
Bacterial contamination and the permeability of oxygen and water vapor are the main problems scientists are solving.
Another challenge is to prevent the accumulation of too much ethylene around food.
Ethylene is a compound naturally released by fruits and vegetables and contributes to the ripening process.
However, the excess ethylene left under the packaging film can cause food to mature and rot.
To meet the needs of multiple parties.
Functional packaging, Unal starts with polyethylene film.
In order to remove ethylene and provide a gas barrier, the group has added small hollow cylinder clay \"Elohim nanotubes \".
The nanotubes prevent oxygen from entering the film and from escaping water vapor and other gases.
In addition, they prevent ethylene accumulation by absorbing ethylene.
The researchers loaded the nanotubes with a natural antibacterial essential oil, which is present in Baili and oregano, called carvasil, and coated the loaded nanotubes on
The team packed tomatoes, bananas and chicken in a film to test its effectiveness at different times compared to food packaged in plain polyethylene.
After 10 days, the tomatoes wrapped in the new film were better preserved than the control vegetables.
In addition, compared to the control fruit, the new slices help the banana to remain stronger and keep a bright yellow color after six days.
Chicken wrapped with experimental film and refrigerated for 24 hours showed significantly less bacterial growth than chicken in ordinary polyethylene. (
