The invention discloses a method for preparing plasma-activated water PAW and measuring its bactericidal activity, which relates to the technical field of food microorganisms. After the plasma jet device works normally, add 3L of water to make it just over the outlet of the spray gun, and start timing; S3. When the treatment time is 30min, 60min, and 90min, take samples respectively as PAW samples with different treatment times And conduct microbiological experiments, and each group of samples is recorded as PAW-30, PAW-60, PAW-90; S4. After the experiment is over, turn off the power supply and gas source of the host. In the method for preparing plasma-activated water PAW and measuring its bactericidal activity, it can be determined through experiments that PAW has significant bacteriostatic effect on Staphylococcus aureus and Escherichia coli. The inhibitory effect on Escherichia coli is significantly better than that on Staphylococcus aureus. |
