What Is Modified Atmosphere Packaging?

Are you interested in knowing how some of the fruits and other delicate and highly perishable items end up spending so many days on the supermarket shelves? The secret is in a modern technique of packaging known as Modified Atmosphere Packaging (MAP). But what exactly is modified atmosphere packaging, and how does it work? So, let us get to know what is modified atmosphere packaging and more about the truth at the back of MAP packaging.

MAP is a modern technique that is applied to store fresh or slightly processed foods for a longer period. The main principle of MAP is to change the gaseous environment surrounding the food product enclosed in its packaging; thus, this practice contributes to food’s freshness, taste, and safety.

Understanding Modified Atmosphere Packaging

How Does MAP Packaging Work?

Modified atmosphere packaging basically creates an atmosphere within the packaging that hinders the process of spoilage. This is done through:

• Oxygen Reduction:

  Reducing the concentration of oxygen reduces the rate of oxidation processes and also hinders microbial growth.

• Carbon Dioxide Increase:

  Raising the levels of carbon dioxide to prevent bacterial and mold growth on foods being stored in the refrigerator.

• Nitrogen Addition:

  Using nitrogen to displace oxygen and act as a filler gas.

Advantages of Modified Atmosphere Packaging

• Extended Shelf Life:

  Relatively conserve food for a long time.

• Enhanced Safety:

  Reduction of the likelihood of contraction of food-borne illnesses due to the prevention of microbial proliferation.

• Quality Preservation:

  This process retains the flavor, texture, and other food qualities that are essential to the nutritional value of the meal.

• Waste Reduction:

  Prevents the food from getting spoilt and having to be discarded.

• Cost Efficiency:

  Pretreatment helps to minimize the use of preservatives and additives in food products.

Types of MAP Packaging

High-Barrier Films

High-barrier films are applied in MAP packaging to help barrier the flow of gases and/or moisture from inside the package to outside or vice versa. Such films are produced using polyethylene, polypropylene, and polyester.

Vacuum Packaging

Vacuum packing is a process in which all the air that is in a pack is removed either partially or wholly before sealing. This method is suitable for products such as coffee beans, and cured meat products because their exposure to air spoils them.

Gas Flush Packaging

In gas flush packaging, the package is purged with a mixture of gases before sealing to eliminate the air inside it. It is widely used for products such as salads and other types of ‘takeaway’ foods.

Active Modification

This means passing through the packaging a particular gas combination before the packaging is closed. The combination is standardized depending on the kind of food that needs to be packed.

Passive Modification

In this case, the packaging relies on the food’s natural respiration rate to slowly change its internal environment. The type of packaging material should facilitate gases permeating through the package at a desired rate.

Equilibrium MAP

Engages an active and passive approach to achieving a work environment that is neither too aggressive nor too laid back.

Applications of MAP Packaging

Food Industry

MAP packaging is widely used in the food industry for various products, including:

• Fruits and Vegetables:

  MAP lowers the oxygen concentration and raises the carbon dioxide level; thus, the rate of respiration in the fresh produce is slowed down, and this results in fresh and crisp produce.

• Meat and Poultry:

  MAP aids in controlling the levels of oxygen which in turn preserves the red color of meat and also slows down the rate at which pathogenic microorganisms act on the meat.

• Dairy Products:

  MAP packaging helps in the preservation of the shelf life especially for cheese and other dairy products by preventing the growth of mold and bacteria.

• Ready-to-Eat Meals and Seafood:

  Using MAP is most effective for storing pre-packaged meals while still maintaining the quality of stored meals through increased shelf life. Fish and seafood products keep their fresh and good quality by using MAP.

Pharmaceutical Industry

MAP packaging is also employed in pharmaceutical applications in the bottling of vaccines and biological samples to preserve the shelf life by checking oxidation and spoilage.
