How can I wash off the pesticides on fruits and vegetables? It turns out that the most effective cleaning method is it!

Food safety has always been an issue of great concern to our friends. Cutlery, bottles and even toys for babies have to be sterilized one by one. What about food? Eating fruits and vegetables can not be disinfected in a disinfection pot, but pesticide residues are insoluble in water, so it is not easy to wash them with tap water, so what method can be used to wash fruits and vegetables to maximize the removal of annoying pesticides? Is it true that the legendary washing with flour is effective? OK mom got the exclusive test results from her partner at the Chinese Academy of Sciences, including flour, baking soda, shell powder and boiling water, and tried it the same way, using the final test results to tell you what kind of cleaning method is the most reliable.

Although pesticides can not be avoided, we ordinary people should at least know how to remove pesticides. After reading our exclusive test report today, my mother will no longer have to worry about my pesticides.

Detection step

This is the pesticide Ding Ma bought from the rural plant protection station pretending to be a peasant woman, one is organophosphorus, the other is pyrethroids. These two types can be said to be the representatives of pesticides commonly used by farmers!

This is our experimental subject. Beans represent vegetables and grapes represent fruits. When testing, the boys of the scientific research team will follow the example of the farmer's uncle and spray two kinds of pesticides on the two representatives.

These are our protagonists today, all kinds of pesticide cleaning products! These include flour that grandma and grandma love to use, shell powder that fashionable cool mothers like to use, baking soda and rapeseed powder that environmentalists love to use, and expensive fruit and vegetable cleaners.

Specific operation method

1. Flour: add 5g flour to 1 liter of water, soak the ingredients for 10 minutes, then rinse once under tap water.

two。 Baking soda: add 5g baking soda to 1 liter of water, soak the ingredients for 10 minutes and rinse twice under tap water.

3. Tea seed powder: add 5g tea seed powder to 1 liter of water, soak the ingredients for 10 minutes, rinse once under tap water.

4. Cleaning agent: 4-5 drops of cleaning agent to add 1 liter of water, add ingredients to scrub (no soaking time), rinse twice under tap water.

5. Tap water: soak the ingredients in 1 liter of water for more than 20 minutes and scrub 3 times under tap water.

6. Boiled water: put the boiled water into the ingredients for about 5 minutes and rinse once under tap water.

7. Shell powder: add 2g shell powder to 1 liter of water, soak the ingredients for 10 minutes and rinse twice under tap water.

Test result

It's time to get serious, so which method is the most effective?

absolutely unexpected! It turns out that the most effective thing is to wash the boiling water without spending a penny, and the percentage of removal of the two pesticides has reached 94% and 83%! It's a pity that we can't blanch fruit with boiling water.

Result interpretation

Summary

1) although the popular tea seed powder and flour help to absorb oil stains, they are still not strong enough for cleaning pesticides. It seems that the method of washing grapes with flour invented by the Chinese is not very reliable; moreover, it is reported that tea seed powder will deposit in the pipeline to attract cockroaches, so it is not recommended to use it.

2) Fruit and vegetable detergents and baking soda seem to be good cleaning methods. It should be noted that rinse with clean water several times after soaking to prevent cleaning agent pollution.

3) if the vegetables are blanched in boiling water after washing, the pesticides will be basically cleared!
