Hypochlorous acid ice has gradually become a new non-thermal sterilization and fresh-keeping technology.

In recent years, hypochlorous acid water ice has gradually become a new non-thermal sterilization and fresh-keeping technology. This technology not only has the low-temperature advantage of ordinary ice, but also combines the characteristics of hypochlorous acid water with quick, broad-spectrum microbial killing and good fresh-keeping ability, and has the advantages that the acted hypochlorous acid water ice can be completely reduced into non-toxic and residue-free ordinary water, and has no pollution to the environment after discharge. It has a broad application prospect in the fresh-keeping of aquatic products.

In 2021, many places in China reported that the outer packaging of cold-chain goods tested positive for novel coronavirus nucleic acid, and the novel coronavirus epidemic caused by cold-chain goods occurred from time to time. In order to solve the urgent need of national epidemic prevention and control, on December 31, 2020, the General Office of the National Health and Health Commission issued the Technical Requirements for Hygienic Safety Evaluation of Low-temperature Disinfectants, which provided guidance for the detection and listing of low-temperature disinfectants. Hypochloric acid disinfectant, as an environmentally friendly, safe and efficient disinfectant, was widely used during the epidemic in COVID-19.
