Fruit and vegetable cleaners evaluation
many parents are hesitant to plant grass products.
In the past, cleaning fruits and vegetables might only be concerned with removing dust stains from the surface. Nowadays more and more parents pay attention to the residues of fruits and vegetables. Can they wash them away? How long will it take to wash? Will it remain? It has become a thorn in the hearts of many parents.
Demand is the market and business opportunities, so the “fruit and vegetable cleaning artifact” came. Can wash dishes, but also go to agricultural residues, sterilization, the use of ultrasound, electrolytic water and ozone and other “tall” technology, the effect of almost 100% of the propaganda, plus a variety of visual effects, wow, right, this is the feeling of heart!
Unexpectedly, there is no truth about the actual effect. We have collected and purchased 6 kinds of fruit and vegetable cleaners to test it.
If you are patient, please drag it to the end of the article to read the essence.
Testing Laboratory: Southern Testing Center of China Inspection and Quarantine Research Institute (Zhejiang Jiuan Testing Technology Co., Ltd.)
Test cost: machine 8780 + sample 367.4 + test 14000 = 23147.4 yuan
Special thanks to the enthusiastic fans Changchun Li Dad, Hangzhou Zhangma and Hangzhou Xiaolei for their samples of fruit and vegetable cleaners, which saved us a lot of money. Thank you!
Public Number Replies to “Fruit and Vegetable Cleaner” to See Product Details
We went to the supermarket to buy rape and strawberries.
Four common pesticides, chlorpyrifos, imidacloprid, acetamiprid and dimethoate, were selected and sent to the laboratory with the fruit and vegetable washing machine on the same day.
Clean the rape and strawberry and dry them. Spray the mixture of diluted pesticides on the sample evenly.
Wash rapeseed and strawberry with fruit and vegetable cleaner and other methods to detect the residual content before and after cleaning.
The experimental results of the removal rate of agricultural residues in rapeseed are as follows:

The experimental results of strawberry pesticide residue removal rate are as follows:

Two sets of data were sorted out and several cats were found.
Aren’t they all claimed to be able to remove more than 90% of the agricultural residues?
In fact, rapeseed can remove up to 80% of the agricultural residues, although less than 90%, but it seems to be OK. The removal rate of strawberry pesticide residue is generally below 60%, which is sad.
Look carefully again, it seems that something is wrong.
Businessmen say they experimented with apples, perhaps because they had a smoother surface.
But it feels like cheating, with a smooth, hard, big apple on one side and a pitted, soft strawberry on the other. Can you wash strawberries with the power of washing apples?!
Moreover, we found that dimethoate was mentioned in the test reports and commodity publicity issued by the merchants. Why?
From our test results, dimethoate is the most easily removed pesticide, but how can we buy fruits and vegetables only with this pesticide?
In order to make the comparison more intuitive, we added the data of removing agricultural residues after hand washing and hot water. The emphasis is on:
We were surprised to find that there was no big difference between hand washing and machine washing. Even compared with No. 4 and No. 6 washing machines, the removal rate of hand washing is a bit higher!
This makes me somewhat unacceptable, I spent so much money to buy you this “artifact”, even better than my own hand washing?!
In addition, some people will be used to boiling water before eating, think that boiling water can “kill some dirty things”, but our measured data show that hand washing is better than boiling water.
It seems that friction and rubbing are very important in hand washing process, and mechanical force can help us to get rid of agricultural residues better. In addition, running water is also a big assistant.
This is my special Tucao!
Have any friends found that our measured data, known as the sink can wash dishes, but also to the farm remnants of the 3rd square T dishwasher, its data is very “fantastic”.
The effect of removing chlorpyrifos poisoning from rapeseed was astonishing, up to 99%, far exceeding the data of the other five machines.
However, the effect of removing the other three kinds of agricultural residues is negligible, while the effect of the other five machines for these three kinds of agricultural residues is very good.
You are tall, I am low, you are low, I am tall. Come on, I am not buying you to complement each other. I can only remove a kind of farm disability efficiently, and dare to call it “go farm disability”??
For fear of blaming the high-end technology of the merchants, we have designed another test scheme – adding diluted pesticides directly into the machine, without adding fruits and vegetables, and starting operation. The result is very touching.
It can be seen that acetamiprid and dimethoate have hardly been removed, and the other two are just talking better than nothing. It shows that the removal of agricultural residues depends not on the “principle and technology” of the cleaning machine, but on the “washing”.
Then the question arises – what is the ghost of the foam washed out in the manufacturer’s advertisement? Are those farm or animal remnants?
We bought some pork and washed it twice to show you the effect.
Wash twice, all have such foam. If these foams imply the residue of farm animals, can the meat still be eaten? I didn’t go on washing. But common sense tells me that the same is true for the third and fourth washes.
Because it’s just protein in food that acts as a surfactant. It’s like soap and water. You can always stir up bubbles. These foams come from pork itself, not from farm animals. So if you wash it many times, you will still have it.
So far, the evaluation of fruit and vegetable cleaners is over. In addition, we also measured
