Packaging of food

Food does not remain eternally fresh. Milk becomes sour, meat changes colour and smells, bread becomes mouldy… The putrefaction of food is caused by various factors. Oxygen in the packaging plays an important role in this. Food suppliers try to keep products as fresh as possible and want to create a longer shelf life for their food.

This can be achieved thanks to the packaging of foods under a protective atmosphere, Modified Atmosphere Packaging (MAP). This gas packaging is the result of removing the air present from the packaging and to replace by a mixture of gas that has protective and reactive properties. The propellant gas contains various gases such as carbon dioxide, oxygen or nitrogen, depending on the product to be packaged.

Food has far ranging characteristics. The propellant gas must therefore be composed very accurately if one wants to get the correct result. In the event of Modified Atmosphere Packaging, after the introduction of the gas, the packaging is hermetically sealed so that there is no external air being introduced into the packaging any more.

Applications for Modified Atmosphere Packaging

The diversity of food that can be packed by means of Modified Atmosphere Packaging is enormous. Fresh meats, poultry, fish, pizza, bakery products, ready-made meals, cheese, vegetables, fruit, nuts and olives are just a few of the areas of application of packing gas.

Requirements

To adapt the principle of MAP you need different things:

• Packaging machine
• Suitable foil
• Gas (may vary between bottles, frameworks, micro bulk to tanks of 54 tonnes)
• Reducer
• Heater (Optional)

Advantages

Packing gas ensures a longer shelf life for your products. Products will spoil less quickly and will stay longer fresh and attractive. Thanks to packing gas, you restrict the use of other additives. In relation to the costs of the delivered product, the one for laughing gas is only small.

In a row:

• Longer expiry date
• Less decay
• Products remain fresh and attractive
• Less use of other additives
• Cheap
