Ultraviolet (UV) disinfection is a kind of efficient, safe, environmental protection, economic technology, broad-spectrum sterilization effect, can kill a variety of microorganisms including bacteria, mycobacterium tuberculosis, bud and fungus, and almost does not produce any disinfection by-products. In principle, all food production and processing sites can install ultraviolet sterilizer lamps for air disinfection.
In food processing plants, the food processed daily on the production line is generally disinfected with ultraviolet disinfection lamps. This is because the UVC ultraviolet lamp sterilization and disinfection method has the characteristics of environmental protection, rapid disinfection, no secondary pollution and low cost. Ultraviolet disinfection lamps are also the mainstream sterilization method in the food processing industry. In particular, the outbreak of the new crown epidemic has imposed stricter requirements on the food processing industry. UV disinfection lamps have become the first choice for the food processing industry.
In the food processing industry, UVC ultraviolet germicidal lamps have been very popular, but the popularity of ultraviolet disinfection lamps in people's daily life is a bit embarrassing, especially for household food disinfection. People's understanding of ultraviolet rays is still at the "primary stage" level. Due to the insufficient understanding of UVC ultraviolet rays, people are often worried that ultraviolet radiation will remain on the surface of food sterilized by ultraviolet disinfection lamps, and secondly, they are also worried about the most ultraviolet radiation. Will food cause changes in its own traits?
So, can the food that has been irradiated by the ultraviolet disinfection lamp be eaten? Is there any ultraviolet radiation residue on the food surface? The answer is edible.
In terms of disinfection methods, the sterilization results of heating and ultraviolet disinfection are the same. Ultraviolet rays are electromagnetic radiation between 10 nanometers and 400 nanometers. When bacteria in food are irradiated by ultraviolet disinfection lamps in the UVC band, deep ultraviolet rays are absorbed by bacteria and viruses, which will destroy the DNA base pairs of bacteria or viruses and make them unable to replicate. The DNA molecules destroyed by ultraviolet rays are decomposed after entering the human body without producing harmful substances. Therefore, the use of ultraviolet disinfection lamps to disinfect food does not have safety problems, and foods that have been treated by ultraviolet lamps can be enjoyed boldly.
