MAP Technology and its Benefits for Your Packaging Operations

Posted by Nichrome India Ltd on June 21st, 2022

MAP or Modified Atmosphere Packaging is a widely used technique of preservation when it comes to food packaging. MAP technology like that in a tray sealing machine is gaining more and more popularity as a method of preserving freshness and lengthening the shelf life of fresh foods - fruits, vegetables, meat, dairy products and more. It is a notable method of preventing spoilage and extending the shelf life of various food products.

So what is MAP technology? 

Atmospheric air is a combination of 3 elements - N2 (79%), O2 (20.96%), CO2 (0.04%) and traces of inert gases and vapour. 

MAP packaging, sometimes known as controlled atmosphere packaging, is the method of modifying the makeup of the internal atmosphere of a package using a modified atmosphere packaging machine - usually food packages and medicines - in order to improve the shelf life of the packed products.

 This technology was developed to deal with the short shelf life of certain food products such as meat, fish, poultry and dairy in the presence of oxygen. The presence of oxygen in the packaging leads to the lipid oxidation of the food product. Oxygen contributes to the shortened shelf life of fresh produce because it leads to high respiration rates. Even microbiologically, Oxygen catalyses the growth of aerobic spoilage microorganisms. 

It is plainly obvious that a reduction in oxygen and its replacement with more suitable gases can deter or reduce oxidation reactions and microbiological spoilage. 

MAP food packaging using a MAP tray sealer generally involves the lowering of the amount of oxygen in the headspace within the package. Nitrogen - a comparatively inert gas - or carbon dioxide can be used to replace oxygen. 

The use of active techniques such as gas flushing and compensated vacuum, or passive ones like designing ‘breathable films’ can be used to achieve a stable atmosphere of gases inside the packaging. 

The different components of MAP Technology 

1. Machine
2. Gas mixer
3. Gas analyser
4. Trays
5. Barrier film 

Why MAP Technology? 

• Convenience
• Quality
• Safety
• Availability
• Brand image
• Extended shelf life
• Sensory aspects 

Advantages of MAP Technology 

• Maintaining the quality throughout the manufacturing process (GMP) (GHP)
• Maintaining protocols for food safety and HACCP
• Consistent productivity with limited manpower
• Can handle a variety of products and is capable of handling different SKU sizes 

Benefits of MAP Technology 

• Shelf-life extension
• Waste minimisation (profit maximisation)
• Quality
• Reduced need for artificial preservatives, maintaining the
• Increased distribution possibilities 

Why maintain gas mixtures?

How does MAP control micro-organisms?

MAP can control 4 types of micro-organisms:

• Aerobic Microbes – require oxygen or air for respiration and growth    
• Anaerobic Microbes - do not require oxygen or air to grow     
• Microaerophilic Microbes – require a low level of oxygen for optimum growth
• Facultative Anaerobic microbes - can respire and grow with/without the presence of oxygen

 MAP for shelf-life and food spoilage

• Remain safe
• Be certain to retain desired sensory, chemical, physical and microbiological characteristics
• Comply with any label declaration of nutritional data when stored and handled under the recommended data

 Factors that influence shelf-life

• Raw materials
• Product formulation
• Processing
• Packaging atmosphere
• Hygiene
• Distribution
• Storage
• Consumer handling
