1 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.
What is ROX? 2 R: Reduction - Alkaline water OX: Oxidation - Acidic water ROX is the name of E-water production system. ROX generates Alkaline water and Acidic water from only tap water and salt. Both E-water can be used in food sanitation.
Generation principle 3 〈 REACTION 〉 ［ Anode ］ H 2 O → ½ O 2 + 2H + + 2e - 2Cl - → Cl 2 + 2e - Cl 2(aq) + H 2 O ⇔ HCl + HClO ［ Cathode ］ H 2 O + 2e - → ½ H 2 + OH - Na + + OH - → NaOH At the anode, the chlorine gas (Cl 2 ) is generated from the chlorine ion (Cl - ). The hypochlorous acid (HClO) are generated as the chlorine gas (Cl 2 ) reacts with water (H 2 O). Water (H 2 O) decomposes and becomes oxygen (O 2 ) 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 (H 2 O) decomposes and becomes hydrogen (H 2 ) and hydroxyl ion (OH - ). Sodium hydroxide (NaOH) is generated by sodium ion (Na + ) and hydroxyl ion (OH - ).
Substances contained in acidic E-water Chlorine changes its existence form depending on the pH of the solution. As the pH of acidic E-water is around 3.0, it consists 85% hypochlorous acid ( HClO) and 15% chlorine gas (Cl 2 ). 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. pH 1 2 3 4 5 6 7 8 9 10 11 100 Cl 2 ClO - HClO 0 80 60 40 20 Existence rate (%) Acidic E-waterSodium Hypochlorite (diluted) The existence form of chlorine 4
Substances contained in alkaline E-water Alkaline E-water contains as an active ingredient a small amount of sodium hydroxide (NaOH) capable of dissolving proteins and emulsifying oil and fats. It is also useful for neutralization following disinfecting with acidic E-water. Fat/oil emulsification 1ml of cooking oil dripped into 10ml each of tap water and alkaline E-water Completely separated Emulsified Protein dissolution Egg yolk applied and dried on a stainless steel sheet and agitated in hot water and alkaline E-water 50ºC hot water Agitated for 60 min 50ºC alkaline E-water Agitated for 12min 5
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… Hand washing Washing and disinfection of utensils Disinfection of Vegetables Disinfection of seafood Deodorant of rubbish And those effects are… 6
Customer ’ s voice Washing ・ Disinfection ・ Deodorant If it is E-water Washing ・ Disinfection ・ Deodorant can be safety done. We asked the effect of E-water to customers who used it. Hand washing Alkaline Acidic We can wash hands easily, and eliminate odour. Cutting-board Kitchen-knife Alkaline Acidic Tap water （ only metal ） Smell is removed by E-water, and we can start to the next job. 7 Cloth We can remove fish oil and smell. The cloth is not worn-out and it lasts long. Alkaline Acidic Wooden utensils Soaking in E-water cleans difficult to reach areas. Alkaline Acidic SUSHI-case Cleanness is important, because it is seen by everyone. Smudges don’t adhere to the glass. Alkaline Acidic Refrigerator Not only the exterior, it can clean shelf, knob and etc, if they are dirty. Alkaline Acidic Tap water （ only metal ）
Fryer Please drain the oil. Next, collect warm alkaline water, then wipe with sponge. Fryer will be cleaned easily. Alkaline Tableware 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. Alkaline SUSHI bar If E-water is used, plain wood counter is not damage. Alkaline Rubbish Acidic Flush the liquid that comes out of rubbish with acidic water. Bad smells are removed, and pests don't approach. Tables, Seats After wiping, it is fresh. When we are busy, can easily clean it. Alkaline TATAMI-mat Alkaline water can clean cigarette's tar. We don’t worry because chemical doesn’t remain. Alkaline 8 Gully, Weeper When E-water is drained away it dissolves dirty fat and smells in your drains. Alkaline Acidic Tap water （ only metal ） Toilet Acidic water can remove ammonia odour by neutralizing. Alkaline Acidic Kitchen floor Alkaline Floor keeps clean, we don’t slip on the floor.
Seafood For disinfection of surface. It is effective also for “Vibrio”. Shellfish It is effective also for “Norovirus”. Vegetables We can disinfect it quickly, and not reduce the nutritional value of the ingredients. Eggs It is effective also for “Salmonella” Disinfect by acidic water Rinse by tap water 9 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.

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
