Ozone on my apple

Do you wash that luscious and juicy red apple before eating it? What about those fresh, green vegetables? Oh, talking about the importance of washing fruits and vegetables with you is passé, is it? You already know how to prevent the risks of getting water and food-borne diseases? Then this story is aimed right at you.


Now that the importance of washing fresh produce in your household has been established, let us move on to the next set of questions. How do you wash your produce? How do you become sure you have removed the dust, pesticides and chemicals?

These are exactly the questions a lot of healthcare product companies will ask you while promoting their new product – a vegetable and fruit purifier. It is almost as if these companies had a collective conscience calling. Result? Confused buyers (you and us), wondering whether and how these purifiers work. Is washing fruits and vegetables with tap water really not enough?

How does a purifier work?

One of the technologies being touted these days is: Ozone disinfection. How does it work? Well, it produces highly reactive ozone gas that oxidises traces of pesticides, insecticides and other harmful farm chemicals. Put your fruits and vegetables in a purifier. Switch it on for a few minutes and bingo! Your clean produce is ready to be consumed.


What should you do?

We recommend you call up the company for a free demonstration and only if you are satisfied, pay up the not-so-small price for it. The prices range between Rs 5,000 and Rs 6,000.

Purifiers apart, there are new, evolved versions of the good old water purifier also available in the market. Kent, a famous and highly-advertised company, has recently launched a “Gravity based Ultra Filtration (UF)” water purifier that can remove arsenic and fluoride contaminants from drinking water.

Technology gyaan: The UF membrane works under the force of gravity and at atmospheric pressure. With a pore size of 0.1 microns, it filters out bacteria as well as harmful micro-organisms. It is used in combination with fine nylon filter which removes dust and sand, as well as, carbon filter that is coated with nano-silver. This nano-silver coated carbon filter absorbs many organic impurities and dissolved gases in water.

So go ahead, do more research before taking any decision. In the meanwhile, here are some easy and inexpensive ways to keep raw fruits and vegetables safe. Some of them might seem obvious, but we would like to highlight them nonetheless:

  • Use clean water to wash your fruits and vegetables.
  • Vegetables like cauliflower or cabbage should be soaked for a few minutes.
  • Wash leafy green vegetables by soaking them in a bowl of water for a few minutes. Drain. Repeat. Dilution does the trick.
  • You might also consider presoaking your green vegetables in a mixture of vinegar and water: 1/2 cup distilled white vinegar per two cups water. Rinse with clean water.


Ozone: How it kills bacteria

Ozone is one of the strongest oxidants that can kill bacteria and other harmful micro-organisms. It does so by oxidation, a process that destroys membrane structure of harmful micro-organisms. Dissolved ozone is considered even more potent. Its benefits include the lack of potentially harmful by-products like trihalomethanes (THMs).
