Active Modified Atmosphere Mackaging Fresh Meat MAP Trays

EVOH Barrier MAP Tray refers to a type of food packaging tray used in the Modified Atmosphere Packaging (MAP) process. EVOH High Barrier Tray is made of a layer of Ethylene Vinyl Alcohol (EVOH) barrier material, which is known for its excellent gas barrier properties.

The MAP process involves modifying the atmosphere inside the package by replacing the air with a specific gas mixture that helps preserve the quality and freshness of the food for a longer time. This gas mixture usually consists of carbon dioxide, nitrogen, and sometimes oxygen, depending on the type of food being packaged.

The EVOH layer in the MAP tray acts as a barrier to the gases in the atmosphere outside the package, preventing them from entering and affecting the quality of the food inside. This helps to extend the shelf life of the food and maintain its taste, texture, and appearance.

MAP Trays with EVOH barriers are commonly used for packaging meat, poultry, seafood, and other perishable food items. They are also popular in the food service industry as they provide an effective and convenient way to transport and store food while maintaining its quality and safety.

Study on Preservation Technology of Pork Modified Atmosphere Packaging

In this experiment, the fresh-keeping technology of pork modified atmosphere packaging was studied under the condition of -2℃ micro-freezing. The results showed that: in the range of 40% concentration, the higher the concentration of CO2, the more obvious the antibacterial effect, but CO2 will also make the meat sour and produce unnatural brown color; 02 can make the pork appear bright red, but it will also accelerate Corruption; through the C02 and O2: combined test results, it is determined that the gas ratio of modified atmosphere packaging for pork under slightly frozen conditions is 40% C02 + 60% O2, and its fresh-keeping period can reach 24 days.
The effect of packaging materials on the fresh-keeping effect of pork slightly frozen modified atmosphere packaging In this experiment, the effects of different barrier properties of packaging materials on the fresh-keeping effect of pork were studied under the conditions of -2℃ slightly frozen and 40%CO2+60%O2 modified atmosphere packaging. The results show that the PET/CPE packaging bags with medium barrier properties have a good preservation effect, and the preservation period can reach 27 days, followed by PE/PA/EVOH/PA/MPE packaging bags with high barrier properties, and PA, ff'E with low barrier properties. The preservation effect of the packaging bag is very poor.
Based on the above research results, a good process for the preservation of pork micro-freezing modified atmosphere packaging is: use medium barrier PET/CPE packaging bags for modified atmosphere packaging, the gas ratio is 60% 02 + 40% C02, and directly put in after the packaging is completed. Store at -2°C in a slightly frozen condition.
