Modified Atmosphere Packaging (MAP)  [ Return towards  Applications  ]

• Technical corner

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

This preservation technique:

• maintains the visible and perceptible quality of the product (appearance, color, texture and taste) as well as its invisible quality (protection against micro-organisms)
• lengthens product lifetime
• addresses the preference for "natural" products and reduced preservatives.

MAP helps eliminate or reduce potential product deterioration. The matrix below describes how you can choose the right gas to prevent a specific type of degradation.

• 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, pre-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 a source of film to protect the product. By optimizing the parameters, MAP can provide a highly successful solution. Our diagram below maps the pathways:

 

• 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 packaging solution of choice.
Thanks to our extensive partnership with food producers world-wide, we have the experience to address a broad range of long-standing and more recent food concerns. The table below shows MAP’s key advantages. Check out if they are suitable for your requirements.
