What is Modified Atmosphere Packaging? Modified Atmosphere Packaging (MAP) is one of the most advanced technologies in food packaging.
This technique, which replaces the air inside the packaging with a mixture of selected gases, offers numerous advantages for the preservation of food products, extending their shelf life and keeping their organoleptic properties intact.
In this article, we will explore the latest innovations in the field of modified and controlled atmosphere food packaging, looking at emerging technologies, the materials used, the advantages offered and some success stories.
Introduction to innovations in food packaging
Over the last few years, the food packaging sector has witnessed significant innovations, especially in response to the need for sustainability and preservation of food quality.
At the same time, modified atmosphere packaging has evolved significantly with the introduction of new technologies that optimise the preservation of fresh produce, minimise the use of preservatives and extend the shelf-life of food. These innovations are crucial to ensure that food products maintain freshness and safety throughout the distribution cycle.

New technologies and materials used in modified atmosphere packaging
Modified Atmosphere Packaging (MAP) has seen significant innovation in both the materials and technologies used. New materials used in MAP include advanced polymers and fibre-based solutions designed to improve barrier properties and reduce environmental impact.
These materials maintain an optimal internal environment for food preservation, protecting it from oxidation and bacterial growth.
Packaging technologies have also evolved significantly. Modern MAP machines are equipped with systems that precisely control the gas composition inside the packages, ensuring that the gas mixture, often nitrogen, carbon dioxide and oxygen, is kept constant to preserve the freshness and quality of the food.
In addition, advanced sensors and improved sealing techniques ensure that packages are hermetically sealed, preventing external contamination and extending food shelf life.
Use of gases in food: reference regulations
The specific requirements for the use of gases in contact with food differ from country to country. However, it is EC Regulation 1333/2008 and EC Regulation 231/2012 that define the gases used in the modified atmosphere packaging process as food additives and impose a minimum purity for each gas that is used. For example, a minimum purity of 99% is required for nitrogen.

Practical applications of MAP packaging
Controlled atmosphere and modified atmosphere are two useful methods of storing perishable foods and are used in specific contexts. Typically, controlled atmosphere is used for food storage in cold rooms or containers, using special sensors and instruments to monitor the gas mixture.
Modified or protective atmosphere (MAP) is often used for food packaging. Some of the most common applications include:
- Fruit and vegetables. Fruit and vegetables are often sensitive to oxidation, so Modified Atmosphere Packaging (MAP) can extend their life, allowing for better distribution of fresh produce.
- Dairy products. Cheese and butter, for example, can benefit from reduced oxygen in the packaging environment to prevent fat rancidity.
- Meat and fish. These products require precise control of the atmosphere to prevent bacterial growth and maintain fresh taste.
