Modified Atmosphere Packaging (MAP) 

Technical corner

MAP focuses on solid and pasty foodstuffs. For liquids, we have developed inerting applications. 

This preservation technique:

• maintains the visible and perceptible quality of the product (appearance, colour, texture and taste) as well as its invisible quality (protection against microorganisms), 
• lengthens product shelf life, 
• matches the preference for "natural" products and reduced preservatives.

MAP helps to eliminate or reduce potential product deterioration.

Successful outcomes through a mix of elements

This preservation technique covers many types of products:

• fresh products such as meat, delicatessen products, pizza, bakery and pastry products, grated cheese, prepared vegetables, and cooked dishes, 
• dried products such as peanuts, milk powder, coffee, and potato flakes.

To use MAP, you must own or acquire a packaging machine and special film to protect the product. By optimizing the parameters, MAP can provide a highly successful solution. 

Air Liquide and MAP gases

MAP is now used worldwide, but has varying levels of penetration due to different consumer habits. It is a highly natural technique, and in many countries it is the preferred packaging solution. 
Thanks to our extensive partnership with food producers worldwide, we have the experience to address a broad range of long-standing and more recent food concerns. Beyond a wide range of food grade gas mixtures, ALIGAL™ for MAP encompasses a full range of equipment and services like:
