Food liquid nitrogen is a high-purity cryogenic gas widely used in various food-related industries. It is regulated by the standard GB 29202-2012 and has a minimum purity of ≥ 99.0%. This gas is typically supplied in two main forms: tank gas supply and Dewar gas supply, both of which facilitate large-scale storage and transportation. Its applications span across multiple sectors, including food processing, beverage industry, medical treatment, seafood processing, fruit and vegetable processing, dairy products, baking industry, food packaging materials, food additive production, and cold chain logistics.

Detailed Description
Food liquid nitrogen is a vital component in modern food processing and preservation. Its high purity (≥ 99.0%) ensures it is safe for use in direct contact with food products. The extremely low temperature of liquid nitrogen (-196°C) allows for rapid freezing, which helps retain the nutritional value, flavor, and texture of perishable items such as fruits, vegetables, seafood, and dairy products.
In the food and beverage industry, liquid nitrogen is used for rapid chilling and freezing processes, ensuring products remain fresh during packaging and transportation. In medical applications, it is used for cryotherapy and the preservation of biological samples. For seafood and produce processing, liquid nitrogen quickly freezes products, preventing bacterial growth and maintaining quality.
In the dairy and baking industries, liquid nitrogen cools and freezes products like ice cream and dough, improving texture and quality. It is also used in the production of food packaging materials and additives, providing a stable environment for chemical reactions.
For cold chain logistics, liquid nitrogen maintains low temperatures during transportation, ensuring perishable goods remain fresh. Compliance with GB 29202-2012 ensures the gas meets strict purity and safety standards. The tank and Dewar supply forms offer flexibility for large-scale operations and portable use.
In summary, food liquid nitrogen is a versatile and essential tool in food processing, preservation, and transportation. Its high purity and reliable supply forms make it a crucial resource across multiple industries.
