Effect of Ozone on Fish (Formaldehyde Removal)
One sample of "Kampung Fish" was sprayed with Formaldehyde and left overnight.
The sample was then divided into two portions and treated as follows for the analysis of formaldehyde residue :-
A) Unwashed sample
B) Soaked in tap water with ozone treatment for 30 minutes.
On analysis of the Formaldehyde removal efficiency test, the following results were obtained:
| A) |
Unwashed Sample |
1000 mg/k |
| |
|
|
| B) |
03 Ozone Treated Sample |
0.53 mg/k |
The results showed that the Formaldehyde residue was reduced to low level after O3 ozone treatment.
*The ozone treatment was carried out in 3 litres of tap water using top-Ozone Multi-Functional Ozone Food Sterilizer (FS-505) for 30 minutes.

Effect of O3 Ozone on Vegetables (Pesticide Removal)
One sample of leafy vegetable "choy sum" was sprayed with Lindane and Profenofos, two types of commercially used pesticide. The "choy sum" was then left overnight and divided into two portions and treated as follows for the analysis of pesticide residue :-
A) Unwashed
B) Soaked in tap water with ozone treatment for 30 minutes.
On analysis of the pesticide removal efficiency test by High Performance Liquid Chromatography
(HPLC) and Gas Chromatography (GC), the following results were obtained: -
| |
|
Lindane, mg/kg |
Profenosos, mg/kg |
| |
|
|
|
| A) |
Unwashed Sample |
50 |
5000 |
| |
|
|
| B) |
03 Ozone Treated Sample |
1.02 |
124 |
The results showed that both pesticide residues were reduced to low level after ozone
treatment.*The ozone treatment was carried out in 3 litres of tap water.

Effects of Ozone on Food: Meat and Vegetables
This is an extremely fascinating look at the effect of O3 ozone on foods. The laboratory testing done by these I.O.A. members in Indonesia demonstrates that antibiotics and pesticides are removed by ozonating food in water, and that the shelf life of vegetables may be extended via O3 ozonation.
