Cold-chain transportation is one of the key pathways for long-distance cross-border transmission of pathogenic microorganisms. Traditional high-temperature disinfection techniques are unsuitable for cold-chain environments. Non-thermal disinfection technologies such as ultraviolet irradiation
ultrasound
and chemical reagents suffer from low efficiency
limited adaptability
narrow antimicrobial spectra
and residual harmful substances
making it difficult to fully meet application requirements. Therefore
there is an urgent need to develop novel
safe
and efficient cold-chain disinfection technologies to protect public health. In recent years
plasma has shown broad application prospects in the field of cold-chain disinfection. Numerous studies have shown that the reactive species generated by plasma can diffuse widely throughout enclosed cold-chain spaces
providing broad-spectrum
highly efficient
safe
and stable inactivation of various pathogens. This paper summarizes the current research status of plasma cold-chain disinfection technology from three aspects
namely
plasma discharge types and application forms for cold-chain disinfection
plasma disinfection effects
and plasma disinfection mechanisms. This paper further analyzes current scientific and technical challenges and envisions future development directions
with the goal of offering valuable references for advancing related theoretical and applied research.
