Can industrial nitrogen be used for food?

Industrial ammonia is generally not used for direct food preparation or storage. The main differences between industrial ammonia and food grade ammonia lie in their purity, preparation and storage conditions, and compliance. The following are the main differences between these two types of ammonia:

  1. Purity:

Industrial ammonia: Industrial grade ammonia typically has a lower purity, typically below 99%. This means that industrial ammonia may contain some trace impurities, such as oxygen, water, oil wax, or other substances that are not suitable for food.

Food grade oxygen: Food grade ammonia requires a higher purity, usually above 99.9%. This means that there are fewer impurities in food grade ammonia than industrial ammonia to ensure that it does not have adverse effects on the safety and quality of food.

  1. Preparation and processing:

Industrial ammonia: Industrial ammonia is usually prepared through common gas production and separation methods, and it may come into contact with industrial equipment and pipelines, where there may be some impurities. Food grade ammonia: Food grade ammonia requires strict preparation, treatment, and storage conditions to ensure that it is not contaminated. It usually undergoes additional filtration and treatment to ensure compliance with food safety standards.

  1. Compliance:

Industrial ammonia: Industrial ammonia is not certified and tested for food production, therefore it should not be used in food manufacturing or processing. Food grade ammonia: Food grade ammonia is usually certified and inspected by regulatory agencies to ensure compliance with food safety standards. It can be used for applications that directly connect with food, such as food packaging, freezing, and processing.

In summary, the difference between industrial ammonia and food grade ammonia lies in the purity, preparation and treatment conditions, and compliance of the gas. In the process of food manufacturing and processing, food grade ammonia gas that meets food safety standards should be used to ensure the quality and safety of food. When selecting and using ammonia gas from afar, special attention should be paid to its purpose and the required gas quality standards.
