Ozone washer is the most common vegetable washer in the market at present. In fact, ozone is a strong oxidant, which can destroy the structure of some pesticides and degrade them. This cleaning machine has a good effect on removing easily oxidized pesticide residues. However, it is found that it takes not only a long time but also a high ozone concentration to remove pesticide residues with ozone cleaner.
Usually, the ozone concentration and action time of household ozone cleaners can't meet the experimental standards. More importantly, the harm of small molecular substances produced by the degradation of residual pesticides has not been evaluated, and the risk of these substances may be higher than that of pesticide residues.
Wash fruits and vegetables Note:
First, don't soak the fruits and vegetables you bought for a long time, because soaking for a long time will lose some water-soluble nutrients. The content of carcinogen nitrite will increase if the green leafy vegetables are soaked for too long.
Second, you can add some salt to clean water. Although the chemical composition of salt is relatively stable, it can also remove some harmful substances from fruits and vegetables. However, it is not recommended to add too much salt to clean, because it may affect the taste of fruit.
Third, it is advisable to wash fruits and vegetables with Taomi. Rice produced by regular manufacturers strictly controls the concentration of pesticides and generally does not exceed the standard. There is an insect called "rice weevil" left in some rice, but this insect does not carry bacteria and viruses that are harmful to health. Therefore, it is appropriate to wash fruits and vegetables with rice washing water, but it is recommended to wash them with rice washing water and then rinse them with clear water.
