AI Technical Summary
In existing technologies, chemical disinfectants such as peracetic acid and sodium hypochlorite are commonly used for disinfection of cold chain food packaging. These disinfectants have a pungent odor and are harmful to the human body. Furthermore, cold chain products are not disinfected after being packaged and are directly released into the market, which affects food safety and health.
The disinfection of cold chain food is achieved by using active particles combined with traditional Chinese medicine disinfectant solution. High-energy, high-temperature active particles are generated by ionization equipment and sprayed onto the traditional Chinese medicine disinfectant solution and then applied to the outer packaging of the food. The traditional Chinese medicine disinfectant solution is composed of traditional Chinese medicinal materials such as Terminalia chebula, wild basil, and fig leaves.
It effectively kills Staphylococcus aureus, has excellent disinfection effect and no pungent smell, and improves the safety and quality of cold chain food. The combination of traditional Chinese medicine disinfection solution and active particles significantly improves the disinfection effect.

Abstract
Description
Technical Field
[0001] This invention relates to the field of disinfection and sterilization methods, and in particular to a method for disinfecting and sterilizing cold chain food using active particles. Background Technology
[0002] Food and product safety has always been a major concern for consumers, especially for cold chain products. Cold chain products are at risk of contamination by bacteria or viruses, particularly Staphylococcus aureus, during production, inner packaging, and transportation. Furthermore, the sterilization process is often neglected after the inner packaging of cold chain products is completed. Packaging without sterilization and then transporting or entering the market directly compromises product safety and quality. Moreover, without sterilization, viruses and bacteria can be directly introduced into daily life, impacting people's health.
[0003] In existing technologies, disinfectants used to sterilize food packaging mostly employ chemical raw materials such as peracetic acid, sodium hypochlorite, hydrogen peroxide, and quaternary ammonium salts. These not only have a pungent odor but also pose a safety hazard to human health due to their strong oxidizing properties. Summary of the Invention
