  2. Summary Today a new type of water, “E-water” is the subject of much attention. To manage the sanitation of the food industry, E-water production system ‘ROX’ was developed by HOSHIZAKI. E-water is generated from ‘ROX’, and you can prevent food poisoning by using E-water for food washing and environmental disinfection. Approx. 80% of food poisoning is attributable to bacteria cross-contamination. It is necessary to disinfect utensils & hands during cooking to prevent food poisoning. However the chlorine sterilization often used as disinfectant can’t be used during cooking because of the strong residue. However, E-water can be used easily during cooking, as it leaves no residue behind. We hope very much E-water spreads in Europe, because unlike a lot of chemicals, E-water is safe to human body and environment. 1

  3. What is ROX? ROX is the name of E-water production system. R: Reduction - Alkaline water OX: Oxidation - Acidic water ROX generates Alkaline water and Acidic water from only tap water and salt. Both E-water can be used in food sanitation. 2

  4. Generation principle At the anode, the chlorine gas (Cl2) is generated from the chlorine ion (Cl-). The hypochlorous acid (HClO) are generated as the chlorine gas (Cl2) reacts with water (H2O). Water (H2O) decomposes and becomes oxygen (O2) and a hydrogen ion (H+). As a result, pH of the water of the anode becomes 3.0 or less. And the available chlorine becomes 20-60mg. At the cathode, water (H2O) decomposes and becomes hydrogen (H2) and hydroxyl ion (OH-). Sodium hydroxide (NaOH) is generated by sodium ion (Na+) and hydroxyl ion (OH-). 〈REACTION〉 ［ Anode ］ H2O → ½ O2 + 2H+ + 2e- 2Cl- → Cl2 + 2e- Cl2(aq) + H2O ⇔ HCl + HClO ［ Cathode ］ H2O + 2e- → ½ H2 + OH- Na+ + OH- → NaOH 3

As the pH of acidic E-water is around 3.0, it consists 85% hypochlorous acid (HClO) and 15% chlorine gas (Cl2). In contrast, sodium hypochlorite (ClO-, hypochlorite ion) widely used in the market has a pH of around 10.0. HClO in acidic E-water sterilize approx 80 times faster than sodium hypochlorite solution of the same concentration. The existence form of chlorine 4

It is also useful for neutralization following disinfecting with acidic E-water. 5

  7. Disinfection of Vegetables Hand washing Disinfection of seafood Washing and disinfection of utensils Deodorant of rubbish To prevent food poisoning If you will use E-water, it is easy to disinfect utensils, equipment and ingredients diligently, because E-water is safe. It is effective on most bacteria and viruses. For example… And those effects are… 6

  8. Alkaline Alkaline Alkaline Alkaline Alkaline Hand washing Cloth Cutting-board Kitchen-knife Acidic Acidic Acidic Acidic Acidic Tap water （only metal） We can remove fish oil and smell. The cloth is not worn-out and it lasts long. We can wash hands easily, and eliminate odour. Smell is removed by E-water, and we can start to the next job. Alkaline Wooden utensils SUSHI-case Refrigerator Acidic Tap water （only metal） Cleanness is important, because it is seen by everyone. Smudges don’t adhere to the glass. Soaking in E-water cleans difficult to reach areas. Not only the exterior, it can clean shelf, knob and etc, if they are dirty. Customer’s voice If it is E-water Washing・Disinfection・Deodorantcan be safety done. We asked the effect of E-water to customers who used it. 7

  9. Gully, Weeper Alkaline Kitchen floor Fryer Alkaline Alkaline Acidic Tap water （only metal） When E-water is drained away it dissolves dirty fat and smells in your drains. Please drain the oil. Next, collect warm alkaline water, then wipe with sponge. Fryer will be cleaned easily. Floor keeps clean, we don’t slip on the floor. Alkaline Acidic Alkaline Alkaline Tableware Rubbish SUSHI bar Acidic Mix alkaline water and hot water in pre-wash sink. Add detergent about 1/3 vs. regular usage. Will be clean and detergent can be saved. Flush the liquid that comes out of rubbish with acidic water. Bad smells are removed, and pests don't approach. If E-water is used, plain wood counter is not damage. Toilet TATAMI-mat Tables, Seats Alkaline Alkaline Alkaline water can clean cigarette's tar. We don’t worry because chemical doesn’t remain. After wiping, it is fresh. When we are busy, can easily clean it. Acidic water can remove ammonia odour by neutralizing. 8

  10. In JAPAN, acidic water has been approved as a food additive. It was approved by the Ministry of Health, Labour and Welfare in June, 2002. Vegetables Shellfish Seafood We can disinfect it quickly, and not reduce the nutritional value of the ingredients. For disinfection of surface. It is effective also for “Vibrio”. It is effective also for “Norovirus”. Eggs It is effective also for “Salmonella” Disinfect by acidic water Rinse by tap water 9

  14. Comparison with other disinfectants Sodium hypochlorite ‘bleach’ ・It can’t be used during cooking because of the strong residue. 〈The smell and slimy feeling remains.〉 ・Undiluted solution almost doesn’t have disinfection power. 〈It takes time to dilute.〉 ・The processing time is long. ・When it touches clothes, it makes decolorization. Ethanol ・It is expensive. ・When surface is wet it doesn’t have disinfection power. ・It is damaging to skin. E-water ・It can be used easily during cooking because it has no residue. ・Running cost is cheap and it can be used like a tap water. ・Disinfection time is fast it needs just 15sec. ・It is safe to human body and environment. 13
