Fresh Meat AMP Trays Modified Atmosphere Packaging Food

Fresh Meat MAP Tray is designed to extend the shelf life of fresh meat by modifying the atmosphere inside the packaging. The PP MAP Tray is typically made of a plastic material that is specifically designed for MAP applications, and it is sealed with a PE Lidding Film that is impermeable to gases. The PP Tray is then filled with a specific gas mixture that helps to slow down the spoilage process and keep the meat fresh for a longer period of time.

The gas mixture used in MAP Trays for fresh meat typically includes a combination of oxygen, carbon dioxide, and nitrogen. The exact mixture will depend on the specific type of meat being packaged and the desired shelf life. For example, red meats like beef and lamb may require a higher concentration of oxygen, while poultry may require a higher concentration of carbon dioxide.

EVOH Barrier MAP Tray for fresh meat are commonly used in supermarkets and other retail settings to help preserve the freshness of meat products and reduce waste. They are also popular among food manufacturers and distributors who need to transport fresh meat over long distances.

Modified Atmosphere Packaging(MAP)

Modified atmosphere packaging is one of the most common and effective ways to extend the shelf life of all types of food products, including chilled meats. Reasonable modified atmosphere packaging can not only ensure the hygienic quality of meat products, prolong the shelf life, but also have a good impact on the sensory quality of cooled meat. 

The most commonly used gas components in modified atmosphere packaging are mainly carbon dioxide + oxygen + nitrogen. The use of this gas mixture is mainly from the point of view of controlling microbial growth and organoleptic quality (such as color). The fresh-keeping effect of this form of modified atmosphere packaging on fresh meat mainly depends on the initial bacterial count of the raw meat, the concentration of carbon dioxide, the presence or absence of oxygen in the packaging bag, the permeability of the packaging material, the storage temperature and the gas composition. 

It acts as an inhibitor of microorganisms by causing changes in bacterial synthase and enzymatic reaction rates, as well as affecting carboxylation and deamination reactions. The mixed gas is equipped with a certain proportion of oxygen to maintain the color of fresh meat and inhibit the growth of pathogenic bacteria. 

The modified atmosphere packaging system is a closed system, in which two processes exist at the same time: one is the physiological serialization process of the product, that is, the metabolic respiration process; The exchange process, these two processes make the air-conditioning system a dynamic system. ① Destroy the environment that microorganisms rely on to grow and reproduce; ② It can maintain a certain activity of the cells inside the food and maintain a certain degree of freshness.
