Whether inerting, freezing, slicing or MAP protective gas packaging: We offer products to extend product shelf life and improve food safety and quality.


Frozen gases - carbon dioxide and nitrogen

Liquid nitrogen or cryogenic carbon dioxide are suitable for cooling or freezing food. This application therefore plays an important role in the food industry. Air Liquide can provide you with suitable products for your application in the food industry.

 

Cooling

Frozen products such as pizza, fish or meat dishes are frequently frozen with dry ice, i.e. solid carbon dioxide (CO2), at a temperature of -79°C. This enables a seamless cold chain for suppliers and consumers. In the past, the frequent opening of a refrigeration system was associated with problems. This is hardly a problem when using dry ice, because the dry ice cools the product down again within a very short time.
 

Frost

Cryogenic freezing with liquid nitrogen is an often used method for freezing vegetables, fruit or even for making cakes for the refrigerated shelf. Cryogenic liquefied nitrogen has a temperature of about - 196° C. The very rapid cooling down of the food prevents fruit and vegetables from getting damaged in the cell structure and thus losing their nutrients. This is no longer a problem due to the special gases used in cryogenic freezing.
