A number of applications are based on treatments of food preservation, such as packaging or gasing of vegetables.
For example, gasing of some tuber vegetables (i.g. potatoes) prevents the growth of buds during the stocking period. In some extents, inert gases – which cause asphyxia – can be used, or some waste products produce typical decomposition gases such as methane and hydrogen sulphide.
Grain storage bins and cereal storage areas may produce carbon dioxide. Some fruits may release ethane, carbon dioxide and decomposition materials become dangerous in the nearby areas.
In industrial sausage factories, frozen products are cut by means of nitrogen, therefore they need to be equipped with suitable oxygen detectors to monitor if there are any leaks and safeguard operators' health.
