Packaging in a protective atmosphere - Ali
Ali is a specific range of technologies, products and services developed by Irish Oxygen to meet the various requirements of companies using food gases.
In particular, packaging in a protective atmosphere using Ali is a technology permitting the easy modification of the composition of the gases present in the packages, during the packaging process: it does this, for example, by increasing nitrogen, an inert gas, and carbon dioxide, a bacteriostatic gas, in order to limit the natural speed of deterioration of the food due to the presence of oxygen.
The gases used in the Ali range are all strictly certified as food additives, and are naturally present in the air we breathe: by modifying the percentages of these gases in packaging, their characteristics can be exploited to increase shelf life. Nitrogen and carbon dioxide are the two principal gases used, although oxygen is also used for packaging red meats and certain types of fish. Oxygen, carbon, dioxide and argon are used to improve the conservation of packaged food. Consumers' demand for the conservation of food products using natural technologies has always been one of the main challenges to the food industry, and Ali is an effective, effective response to this need.
Packaging in an Ali protective atmosphere makes it possible to:
- prolong the shelf life of fresh foods, even doubling it compared to packaging in air;
- reduce or avoid the use of those chemical additives employed to reduce the main processes of natural deterioration of the product;
- avoid the crushing caused by vacuum packaging, thus maintaining the original appearance of packaged food;
- improve production efficiency and the efficacy of food product distribution.
