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?

R: Reduction - Alkaline waterOX: 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.

〈 REACTION 〉[ Anode ]H2O → ½ O2 + 2H+ + 2e-

Cl2(aq) + H2O ⇔ HCl + HClO

[ Cathode ]H2O + 2e- → ½ H2 + OH-

Na+ + OH- → NaOH

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-).

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 (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.

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.

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

     We asked the effect of E-water to customers who used it.

Hand washing Alkaline

Acidic

We can wash hands easily, and eliminate odour.

Smell is removed by E-water, and we can start to the next job.

Cloth

We can remove fish oil and smell. The cloth is not worn-out and it lasts long.

Wooden utensils

Soaking in E-water cleans difficult to reach areas.

Not only the exterior, it can clean shelf, knob and etc, if they are dirty.

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.

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

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.
