Modified Atmosphere Packaging Machine
1. Modified atmosphere packaging introduction
Modified atmosphere packaging, in short known as MAP, is the practice of modifying the composition of the internal atmosphere of a package (commonly food packages, drugs, etc.) in order to improve the shelf life. The need for this technology for food arises from the short shelf life of food products such as meat, fish, poultry, and dairy in the presence of oxygen.
The modification process generally lowers the amount of oxygen (O2) in the headspace of the package. Oxygen can be replaced withnitrogen (N2), acomparatively inert gas, or carbon dioxide (CO2).
A stable atmosphere of gases inside the packaging can be achieved using active techniques, such as gas flushing and compensated vacuum.

2. Common gases used for MAP packaging
Three types of commonly used gases in MAP packaging are CO2, O2, N2
CO2: It is a bacteriostatic gas that inhibits the growth and reproduction of bacteria. Its characteristics are:
(1) The best bacteriostasis was in the lag period of the bacterial reproduction curve (the bacteriostasis index was less than (100/100g).
(2) It is easy to dissolve in water and fat at low temperature.
(3) It has bacteriostatic effect on most aerobic bacteria, but not on anaerobes and yeasts.
(4) Usually the minimum concentration of bacteriostasis is 30%.
O 2: It has three functions:
(1) Inhibiting the growth and reproduction of anaerobic bacteria;
(2) Maintain the red color of fresh pork, cattle and mutton;
(3)Maintain fresh fruits and vegetables, metabolism and aerobic respiration.
N2: Inert gases, which do not react with food, are used only as filling gases for mixed gases.
