Scientists have discovered a way to preserve bread for longer periods of time. This method uses plant-derived ingredients instead of chemical preservatives. Their results are published in the Journal of Agriculture and Food Chemistry.

After the bread leaves the oven, it interacts with microorganisms in the air. A blue-green mass will appear on the surface of the bread after a few days. This is why bread contains preservatives and it is used to extend the product's shelf life. But Brazilian researchers have found a way to keep the bread for longer while reducing the release of chemicals. The new method is called "active packaging" and uses natural antiseptic additives to get fresher bread. The compounds used in active packaging come from plants such as oregano and cloves, which have natural antibacterial properties.
Brazilian researchers mixed plant essential oils with water to make edible films. These edible films were placed in plastic bags used to store bread, and the researchers found that the bread could be kept at room temperature for 15 days. Researchers also put sachets of oregano oil in bread packaging. In the experiment, they opened the package every five days to test its effectiveness and found similar results.
The research team said that these technologies can be used in a wider range and have a role in a variety of bread. Now they are using these edible films to test fruits, meat products and dairy products, hoping to get the same results.
