How To Determine The Packaging Cycle Of Food In Modified Atmosphere Packaging Machine

In order to extend the shelf life of food, except for cooked food and air-dried food, most of them are cooked, frozen and vacuum packed, and some even add preservative additives. However, although this method can play a role in extending the shelf life, the food can easily lose its natural flavor and taste. With the rapid development of food packaging technology, the application of modified atmosphere fresh-keeping packaging machine to food preservation can greatly extend the shelf life of food, lock the nutrition of food, and retain the natural flavor.

After years of development, Map Packaging Machine technology is currently in a mature stage and is the only choice for every food manufacturer to maintain the taste of food. The modified atmosphere packaging machine can maintain food for about 7 days, but after consumers open the air-conditioned packaging, the atmosphere and environment will change, but consumers do not know how to distinguish the edible cycle of modified atmosphere packaging machine packaged food, so they may also eat it by mistake. The following two points are how to judge the edible cycle of modified atmosphere packaging machine packaged food.

Carbon dioxide in modified atmosphere packaging: To detect the edible state of modified atmosphere packaging, a different method is needed: to detect the concentration of key carbon dioxide gas in modified atmosphere packaging, and to judge the edible limit after the modified atmosphere packaging changes. Therefore, the time-temperature label is no longer based on the passage of time, but the change in ambient temperature is an indicating parameter.

The smart label is embedded in the inner layer of the cover film of the air-conditioned packaging. The label is yellow in the CO2 environment, but remains the same color until the package is opened. When the CO2 is released, the ambient gas changes, the label officially starts timing, and the indicator light produces a corresponding color change. Bold color change indication. The label will change color over time to indicate when the package is opened. The label is a fully automatic timer for monitoring freshness. These labels are made of smart plastic, so they can adjust their color according to the changes in CO2 in the package.
