Where to use ozone water


How Ozone Water Works for Food Safety

Utensils and equipment sanitation

Utensils used for food preparation often harbor bacteria that are too small for the human eye to see. Traditional disinfectants such as chlorine may not sufficiently remove surface bacteria from such utensils. As ozone is a natural disinfectant, some food preparation facilities may prefer to use an ozone water spray to wipe down utensils.

The BioSure Water Disinfection System (WDS) can be used to disinfect utensils that come in contact with food. It is a simple ozone water machine that uses an advanced electrolytic oxidation process to convert tap water into dissolved ozonated water. This creates an instant, chemical-free sanitizer that is safe to use and kills harmful pathogens such as Salmonella, Shigella, Campylobacter, and E. coli.

Ice and ice makers

Dirty ice machines are a common issue in food preparation and can lead to outbreaks of norovirus. However, most consumers have probably never considered that ice machines are a breeding ground for harmful bacteria, viruses, and microorganisms. Chemical cleaners are often used, however, these can leave behind harmful residue that lingers in water lines and is consumed by unsuspecting customers.

Aqueous ozone can be injected into water lines that supply ice machines, preventing harmful pathogens from building up inside the machine. Ozone water kills bacteria it comes into contact with, so any remaining bacteria is eliminated once ozone water begins to flow through the machine. This ice is perfectly suitable for consumption and is the best solution to combat bacteria-riddled ice machines.

Hand washing

We touch countless numbers of surfaces each day with our hands. It’s vital that those working in contact with food familiarize themselves with hygiene best practices to prevent foodborne illness.

Ozone is a strong oxidant that acts as a natural sanitizer. Installing a BioSure ozone water system prevents food preparation workers from washing their hands with water that has passed through unsanitary pipes. Ozone simply reverts into oxygen molecules after the sanitization process, without emitting any harmful by-products. It protects water lines from biofilm growth and eliminates mold and bacterial growth.

Furthermore, ozone acts 3,000 times faster than Chlorine and is 50 times more effective. Washing hands with ozone water will kill surface bacteria, preventing the spread of infection through unclean hands.

Cross contamination prevention

Ozone water is suitable for use in every step of food production and eliminates the risk of harmful cross-contamination during food preparation. The ozone water treatment does not add chemicals to water as chlorination does, so there will be no chemical residue on surfaces, utensils, or chopping boards after cleaning, preventing cross-contamination. 

Workstation and food contact surface sanitation

Bacteria and microorganisms are all around us, and it’s possible for contaminated bacteria and viruses to survive on surfaces for long periods of time. Over 200 known diseases are transmissible through food, and contact with dirty kitchen surfaces may lead to sickness.

The CDC advises that food preparation staff should take hygiene precautions when using chemicals to clean work stations, as potentially dangerous residue can linger and come into contact with food. One of the benefits of ozone water is that it does not emit any dangerous chemicals or leave behind any harmful residue on surfaces.

Ozone water cleaning previously required expensive machinery and trained specialists for installation. Now, food preparation facilities can easily install a Water Disinfection System (WDS) to water lines in their establishments.

These devices, also referred to as Electrolytic Ozone Generators (EOG), work by injecting ozone into the tap water with the push of a button — killing bacteria, viruses, biofilm, and other dangerous particles within seconds for quick and effective surface disinfection.

The electrolytic ozone water treatment method used by BES Group is safer and produces the highest ozone concentration in the ozone industry.

Large surface and wash down sanitation

The COVID-19 pandemic continues to threaten, and consumers are becoming increasingly aware that frequently disinfecting surfaces prevents the spread of disease and viruses. According to Nara University in Japan, ozonated water can neutralize the virus-host of COVID-19, preventing potential contact infection.

Large surface sanitation with traditional chemical cleaners such as chlorine may leave harmful chemical residues. Ozone water disinfection removes the need for such dangerous chemical cleaners. Ozone water is an environmentally friendly alternative to traditional cleaning products and is perfect for food preparation.

After the sanitization process, ozone simply reforms into oxygen molecules without emitting any harmful by-products. Large surface sanitation with ozone water removes the risk of breathing in potentially harmful chemicals. Using ozone water also reduces recurring costs, as there is no need to purchase expensive cleaning products.

Food purification

A dirty kitchen is a breeding ground for bacteria growth. The Center for Disease Control states that unwashed or inadequately cleaned food is a haven for viruses, bacteria, parasites, and toxins. 

Approximately 17% or 48 million Americans fall ill from foodborne illnesses each year, leading to an estimated 128,000 hospitalizations and 3,000 deaths. This puts a huge burden on healthcare services. However, as ozone is a strong oxidant that acts as a natural sanitizer, such health issues would be avoidable if ozone water were used as part of the food purification process.

Ozone water does not change the taste or smell of food. It leaves no chemical residues that are harmful to our bodies, making it a safe alternative to chlorine. Furthermore, ozone water does not use heat to disinfect so it is safer for food handlers to use. 

Ozone is also better for the environment as it evaporates into oxygen rather than emitting harmful byproducts.

Produce washer integration

Ozone is a pH-neutral solution and does not cause any damage to food products. Ozone water is ideal for produce washer integration as it is odorless and has no taste. Consumers will not know the difference. 

The Hazard Analysis Critical Control Point (HACCP) standards have deemed ozone as safe to be applied as a sanitation solution, and it was approved for food contact by the US Food and Drug Administration (FDA) in 2001. BioSure Professional has received approval from the UK’s leading food lab Campden BRI, proving that ozone performance is as effective as chemical sanitation methods.

Q & A

Frequently Asked Questions

Ozone water vs chemical disinfectant solution. Why is the concentration of ozone water important? What concentration of ozone water is right for my operation?

Aqueous ozone is highly oxidative, roughly 1ppm of aqueous ozone has the same oxidizing power as 50ppm of chlorine-based disinfectants. Your concentration of aqueous ozone is determined for your application. Please speak with a BES representative or a BES certified technician to determine your need.

Fresh salad is a strong seller in my restaurant. Can I replace chemical sanitizer with ozone water?

Yes, absolutely this is recommended for longer lasting fresher tasting ingredients.

BioSure Professional produces ozonated water or aqueous ozone? Does it comply with international off-gas safety standards?

BioSure products use electrolytic, both direct and through PEM generation, to seamlessly create ozonated water directly from the water. Ozonated water is a dissolution of gas and water. The ozone gas is contained in the water. Yes, BioSure products comply with international off-gas standards and are safe to use in ventilated spaces.  

EPA said good ozone up high and bad ozone nearby. After knowing the advantages of applying ozone water, can I use aqueous ozone indoor? What about NOx - a toxic by-product? What is BioSure Professional’s solution?

Yes, aqueous ozone is safe to use inside as long as the space is well ventilated. BES products do not use air as an input and therefore have no harmful waste by-products including NOx. BES uses patented electrolytic technology that produces ozone or ozonated water from water.

Does ozone water affect the taste of food?

No, the BioSure professional ozone water system will not change the pH of the source water, as long as the tap water is neutral water, BioSure produces neutral ozonated water, and it will be reduced to oxygen and water after sanitation. Therefore, it will not remain like chlorine disinfectant and affect the taste of food.

Most ozone generators require frequent air quality treatment to maintain their performance. Why doesn't BioSure Professional need to monitor air quality?

BioSure and BES products use patented electrolytic ozone generation that uses water as the input to create the ozone water. In this way, BioSure and BES products do not need to monitor air quality.

I tried ozone once many years ago on my production line. The ozone off gas was irritating my employees' throats and eyes. What makes me trust BioSure Professional’s safety and performance?

BioSure products are designed to be safe for the workplace. BioSure’s kitchen sanitation solutions offer built-in off-gas destructors or are designed to produce a safe dissolution of ozone water that is not irritating to the skin or lungs.

Does ozone water (aqueous ozone) change the food taste and texture? Will ozone water corrode my stainless steel and kitchen equipment?

No, ozone water will only enhance the freshness and longevity of food while sanitizing it. No, ozone water will not corrode stainless steel or standard kitchen equipment, utensils, and wares. If it can stand quat and chlorine bleach, it will be able to handle ozone no problem.

Ozone in Practice, a Case Study

An example of ozone water with food preparation is a large central kitchen delivery service located in Taipei, Taiwan. As they distribute to multiple other restaurants, it is vital that they use clean and sanitized produce.

Before switching to ozone, the company used chlorine and bleach to soak produce and remove bacteria. They have now installed a BioSure ozone system (WDS) to each sink in their satellite kitchens, using post-filtration ozonated water to clean and sanitize food. This is a healthier and more environmentally friendly alternative to their previous method.

An ozone water sanitation system is a cost-effective alternative to traditional cleaning chemicals. Food preparation facilities do not have to purchase expensive cleaning chemicals once an ozone water system is installed. Ozone is generated on-site so there is no need to transport or store potentially dangerous chemicals, freeing up space and reducing transportation costs.
