Fresh Meat MAP Tray is a type of packaging specifically designed for fresh meat products.
CO2 can inhibit the growth of bacteria and fungi (especially in the early stage of bacterial reproduction), and it can also inhibit the activity of enzymes. The bacteriostatic effect is better at low temperature and the volume fraction is 25%, and it is water-soluble;
The role of 02 is to maintain oxygen Combined with myoglobin, it makes the meat bright and can inhibit anaerobic bacteria, but it also creates a good environment for many harmful bacteria;
N2 is an inert filling gas, nitrogen does not affect the color of the meat, and can prevent oxidative rancidity and mold. Growth and parasitic infestation.
In meat preservation, CO2 and N2 are the two main gases, and the presence of a certain amount of 02 is beneficial to prolong the shelf life of meat. Therefore, an appropriate ratio must be selected for mixing. The gas ratio of modified atmosphere preservation of fresh meat in Europe is 02: C02 : N2 =70 : 20 : 10 or 02 : C02 =75 : 25.
