Problems solved by technology

However, another situation we are currently facing is that the surfaces of all cold-chain foods need to be disinfected, and there are no relevant low-temperature products available in the market. Therefore, the development of low-temperature disinfectants is arduous and urgent
[0004] For some commonly used normal temperature disinfectants, the disinfection ability will drop significantly when the temperature drops or is below zero, especially below zero, all normal temperature liquid disinfection will freeze and cannot function
Even if it does not freeze, its disinfection effect will be doubled, and the effect is worrying

Abstract

The invention belongs to the technical field of disinfection materials, and particularly relates to a low-temperature disinfectant which is simple in process and wide in application range and a preparation method thereof. The low-temperature material, the disinfection material, a corrosion inhibitor, a stabilizer and the like are compounded, and the prepared low-temperature disinfectant can achieve efficient sterilization performance at the temperature of -20 DEG C; and the corresponding disinfection problem under the low-temperature condition (cold storage and all links of a cold chain) can be effectively solved.

Description

technical field [0001] The invention belongs to the field of preparation of disinfection materials, in particular to a low-temperature disinfectant and a preparation method thereof. Background technique [0002] Looking back at the entire cold chain link, there are two types of high infection risk factors: one is that the carrier may be infected during the handling process, and the other is that the disinfection personnel may be infected during the disinfection process. With such frequent infections, the safety and security of cold chain practitioners has received more and more attention. It is imminent whether effective disinfection can be carried out under low temperature conditions before transportation, and whether disinfection personnel can be equipped with disinfectants with high-efficiency disinfection capabilities at low temperatures. [0003] At the same time, regarding cold chain disinfection. One is to restore the surface of the cold chain food to normal tempera...
