Cryogenic Freezing And Biological Preservation

Biomedical: Liquid nitrogen can be used for cell and tissue preservation. Liquid nitrogen can cryogenically preserve cord blood, immune cells, frozen embryos, and sperm. Liquid nitrogen can also be used as a safe cryogenic medium for cryosurgery, liquid nitrogen cryogenic treatment of warts, skin cancer, destroy liver cancer, prostate cancer tissue.

Food industry: liquid nitrogen is widely used in quick-frozen food, seafood, steak, etc. through the liquid nitrogen tunnel to maintain the integrity of the cell structure. Ultra-low temperature mixing in ice cream production to enhance the taste. Liquid nitrogen is also used in cold chain logistics, where liquid nitrogen refrigerated trucks transport high-end fresh food (such as tuna, vaccines). Some coffee is filled with liquid nitrogen to prevent oxidation and keep the coffee flavor lasting.
