Professor Nguyen Lan Dung: Ozone jacuzzi is like purple medicine

According to Prof. Nguyen Lan Dung ozone disinfection machine does not have the ability to kill chemicals like advertising manufacturers but it only kills germs, non-spore bacteria, spore fungi. And bacteria have spores, ozone machines don't work.

Ozone is just like purple medicine

According to Prof. Dung, ozone has an oxidizing effect similar to that of violet. And pesticides that have fallen into vegetable leaves will immediately convert into cell products, how can it be easily withdrawn?

Compared to ozone machines, Professor Nguyen Lan Dung said that purple drugs are much cheaper, but at least studied to kill some bacteria, but are not effective for worm eggs, not to mention them. insecticide.

Just like that, one year Vietnamese people import more than 100 thousand tons of 4,100 pesticides from China, including 1,600 different chemicals, so it is impossible to know what it is. So if we use ozone there will be no effect at all .

Prof. Dung said his family did not use ozone machines since the old days. Although the food safety issue in Vietnam is increasingly alarming, it is not because of that, it is necessary to retaliate on products that are advertised to kill and disinfect chemicals. Each product has only one effect and cannot be shared for all.

According to Prof. Nguyen Lan Dung, his family never used food cleaning machines but used clean vegetables of origin. Specifically, his family has a nephew who grows clean vegetables and regularly uses them. As for pork, GS Dung bought clean pork on the farm that he once helped on Ba Vi.

In addition, according to GS Dung, the use of food must ensure the origin, origin and ingredients in it. At the same time, people should eat non-deep vegetables such as bean sprouts or sprouts . what season to eat instead of spending money on ozone tanks without knowing how bad the effect is.

Just the psychological stage

Associate Professor Tran Hong Con - Lecturer of the Department of Chemistry at Hanoi University of Science, also said ozone machines used in households cannot be cleaned but only solve psychological problems for people.

Before the storm of dirty food, people lost faith in everything, ozone machines gave them that, people did not know if it could be cleaned but it was clear about their psychology more reassuring.

Should use food to ensure the origin, origin, ingredients in it.

PGS Con said that ozone, if absorbed in a water environment containing chemicals, thanks to the strong oxidizing ability of ozone, it can knock off some chemicals and kill bacteria. However, in experiments or advertising people use differently than households.

In households, people take ozone into normal water, put vegetables, meat and fruits in, it cannot kill germs or chemicals on the surface of those foods. Therefore, ozone is useless at this time.

In fact, toxins and bacteria in vegetables and meat are less than organic matter from meat, vegetables and fruits. In that case, oxidation of ozone to organic matter will oxidize rather than go into killing bacteria and chemicals as its original purpose.

Ozone is colorless gas. At low concentrations, ozone does not smell but in high concentrations there is a slightly fishy odor. Because of the combination of chemistry with up to three oxygen atoms, ozone is a powerful oxidizing gas, capable of destroying most organic substances, including rubber, plastic and fiberglass.

Except for gold and platinum, other metals such as copper and chromium are two catalysts that are suitable for ozone to explode if at high temperatures. Because of the strong oxidizing and oxidizing reaction, ozone is also capable of being the most effective antiseptic and antiseptic. But most people use ozone in industrial plants rather than in households.
