Embodiment 1
[0045] Take 100 μL of 104 CFU / mL E. coli suspension and add it on the durian skin with a size of 5*5 cm after being sterilized by 0.1% hypochlorous acid for 10 minutes, and dry it at room temperature before use. Paste the dried durian skin on the upper, middle and lower parts of the durian respectively, and pass through the low-temperature plasma airflow cold sterilization device without deflectors and with deflectors, respectively, with a working voltage of 18kV and a working frequency of 20kHz for 5 minutes. After being sterilized, seal the durian in a plastic bag and let it stand for 1 hour, then cut it into uniform pieces with a size of 1*1cm, put it in a sterile homogeneous bag, beat it for 1 minute, and set it aside. The antibacterial effect was determined by plate counting method. See Table 1 for the data on the sterilization results of different positions of durian with and without deflectors installed.

Embodiment 2
[0050] Take 100 μL of 104 CFU / mL E. coli suspension and add it on the durian skin with a size of 5*5 cm after being sterilized by 0.1% hypochlorous acid for 10 minutes, and dry it at room temperature before use. The dried durian skin is pasted on the upper, middle and lower parts of the durian, and then the durian is put into the carton, and the core technology device of low-temperature plasma airflow cold sterilization with deflectors is added respectively. The working voltage is 18kV and the working frequency is 20kHz. Treat for 2 minutes, 5 minutes, and 10 minutes; after sterilization, seal the durian in a plastic bag and let it stand for 1 hour, then cut it into uniform blocks of 1*1cm size, put it in a sterile homogeneous bag, beat it for 1 minute, and set it aside . Take the average of the upper, middle and lower parts at each treatment time, and determine its antibacterial effect by plate counting method. See Table 2 for the sterilization results of durian with differe...
