How To Judge Whether The Food Inside The Modified Atmosphere Packaging Machine Is Fresh

In order to better extend the shelf life and edible period of the entire food, many manufacturers will choose expensive Semi Automatic Tray Sealer to package the product. It should be noted that the modified atmosphere packaging machine is very different from the general vacuum packaging. It needs to inject different proportions of carbon dioxide, nitrogen and oxygen to achieve the best preservation purpose. How to judge whether the food in the modified atmosphere packaging machine is fresh? Let's find out.

1. Detect the amount of carbon dioxide in the package

After changing the modified atmosphere packaging machine, the concentration of carbon dioxide in the package can be detected to determine whether the food can continue to be eaten. On the cover of the modified atmosphere packaging machine, a film is embedded in the smart label. When the carbon dioxide concentration is normal, the label color is yellow. When carbon dioxide is released after opening the package, the internal environmental gas will change, and the label color will also change.

2. Color change prompt

After a certain food passes through the modified atmosphere packaging machine, the color of its label will change accordingly with the passage of packaging time to remind the user when to open the package. The label in the packaging bag is an automatic timer, and its main purpose is to better detect the freshness of the food.
For consumers, after purchasing food packaged with modified atmosphere packaging machines, they should open it as soon as possible, so that it will be fresher when eaten. At the same time, for foods that have a long edible time, even if they are packaged with modified atmosphere, they should pay more attention to the change of label color before eating, so as to reduce the possibility of adverse reactions after eating.
