How Does Modified Atmosphere Packaging Protect Food Products?

Modified atmosphere packaging (MAP) is known to prolong the shelf life of food and enhance product safety by limiting the oxygen exposure of fresh and processed food alike. It offers added protection against spoilage, therefore more food industry companies are using MAP to maintain quality and match the increasing demand for packaged food.

If you’re in the food industry, MAP could certainly help you optimally meet the rising consumer demand for well-packed and ready-to-eat food products.


What is Modified Atmosphere Packaging (MAP)?

Modified atmosphere packaging (MAP) is a tried-and-tested packaging solution that controls the air in and around a container or a package, so the food inside stays fresh for an extended period. Which also means the food is safe for consumption for an extended period. 

MAP does this by limiting the amount of oxygen, nitrogen, carbon dioxide, and water vapor inside sealed packages. These elements are generally responsible for discoloration and the change in flavor and texture. Through MAP, oxidation is less likely to occur.

MAP is perfect for fresh fruits, vegetables, and other consumable food products, keeping them fresh for longer and minimizing spoilage.  Coffee beans are another common example of MAP packaged goods. Roasted beans release carbon dioxide; MAP regulates the carbon dioxide buildup to prevent the packaging from bursting open and to keep the roasted coffee beans safely stored.


How Does MAP Affect Food Products?

Modified atmosphere packaging essentially prevents oxidation, preserves food quality, extends shelf life, and minimizes the need for food preservatives. Let’s dig deeper into the ways MAP protects food products and other perishable and consumable items.

MAP Removes Oxygen and Prevents Oxidation

Gas flushing, or the process of increasing the nitrogen level in a package while reducing the oxygen level, is one of the most common ways to prevent oxidation and delay the growth of harmful microorganisms that lead to spoilage. A conservative amount of carbon dioxide is needed inside the package in order to regulate the moisture level.

MAP Protects Food with the Help of Barrier Films

Barrier films serve as an added protection for food products in modified atmosphere packaging. These are plastic films and foils that seal the package and prevent outside gasses from disrupting its carefully balanced level of oxygen, nitrogen, and carbon dioxide. The right type of barrier film can effectively preserve food quality for longer.

MAP Reduces the Need for Food Preservatives

More and more consumers are interested in organic food and food products that are made without GMOs and preservatives. MAP is an ideal packaging type for these food products because it doesn’t use preservatives to limit oxidation and maintain freshness. As such, both consumers and manufacturers understand the appeal of using MAP.


Use MAP as a Cost-Effective Food Packaging Option

Modified atmosphere packaging is a cost-effective type of packaging for consumables and perishables. It contributes to longer shelf life and minimizes food wastage, so less labor is required for product restocking.
