Food processing

Soft fruits, avocados, mixed lettuce; these are just a few examples of delicate foods. To extend shelf life and deliver the best quality products to consumers, there is an effective solution: inerting with nitrogen.

Food processing

Getting fragile, daily fresh products to the end customer (consumer) in the best possible quality is a major challenge for many packing stations and supermarkets. Over-ripening of soft fruit, for example, leads to reduced quality and unnecessary waste. 

An effective solution to extend the shelf life of vulnerable food products is inerting. By adding an inert gas (nitrogen) during packaging, we pause the ripening of the food and extend the shelf life of products such as soft fruit, avocados and salad mixes, but also of meat products such as chicken. 

Modified Atmosphere Packaging (MAP)

The packaging of products under a protective atmosphere is called Modified Atmosphere Packaging (MAP). A commonly used gas for MAP is nitrogen (N2). Nitrogen is an inert gas that does not react chemically.  

It is odourless and tasteless, which makes it ideal for replacing oxygen in packaging and preventing oxidation. Nitrogen can also be used as a stabilising gas, which preserves the volume of the packaging. This prevents a meat pack from bulging, for example. 

MAP packaging can extend the shelf life of meat from 3 to 21 days, cheese from 7 to 180 days and fresh pasta from 3 to 60 days without compromising product quality.

Additional benefits of food inerting

By extending the shelf life of fresh produce through inerting the packaging, you reduce food waste. In addition, MAPing offers additional benefits, such as:

  • Making products more visually appealing - as fresh products retain their colour and structure;
  • Packaging with nitrogen protects the product during transport by means of sturdy, high-quality packaging;
  • Sterilising or cooling products during transport is sometimes no longer necessary;
  • Packing with nitrogen reduces the addition of preservatives. Since MAP packaging already ensures a long shelf life, there is less need to add additional chemical additives (colourants, aromas, flavours, preservatives) to the products.
