Bactericidal power
| General bacteria/pathogenic bacteria spore-forming bacteria/norovirus Sterilization in 30 seconds (80 times stronger than bleach) | Must be used after manufactured at high concentration | Vulnerable to sporogenic bacteria and fungus | Difficulty of guarantee due to unclear component specification of processing |
| Application scope | | Food: 1 ppm (ozone concentration)
Apparatus: No criteria available | Food: 100ppm
Equipment: 200 ppm (separated use) | Food: No notifications
Equipment: 200 ppm |
| Safety | Low concentration chlorine content HOCl is a natural byproduct at the level of tap water generated within human body. | Standards for generation of dissolved ozone harmful to human body: Generation of 0.06 ppm of bromate, reaction to organic matters ▶causing to generate aldehyde | Corrosion due to high residual chlorine. Damages to equipment. Harmful disinfection byproducts. Irritant odor. Harmful to workers | High residual chlorine, Irritant odor, harmful disinfection byproducts. Generation of hydrocarbon/ residual chlorous acid |
| Residual features | Dissolved to revert to water after the use | No residual | Residual sterilization component (unresolved sodium) | Residual chlorous acid |
| Strengths | Quick and potent bactericidal power, non-toxic disinfectant. No odor/no decoloration | Use the liquid as it is. Safe residual features | Many uses | Low effect on pH
Oxidation bleaching action |
| Weaknesses | Disinfection power decreases when reacting to organic matters | Occurrence of harmful substance. High maintenance costs. Ventilation required | Selective use. Damages to equipment. Occurrence of harmful substance | Occurrence of harmful substance
Generation of chlorine gas |
| Rinse | Removal prior to completion of final food product |
is equipment generating slightly acidic hypochlorous acid water (HOCI), an ideal non-toxic disinfectant of HACCP sterilizing 99.9%, in less than 30 seconds, of not only Salmonella, the causative organism for food poisoning, staphylococcus aureus, Vibrio parahaemolyticus, coliform bacillus (O-157), fungus and general bacteria but also various viruses such as norovirus.
