Food safety experts point out that home monitors can be unreliable, and there are three ways to reduce fruit and vegetable intake of harmful substances

There are many food detectors in the workshop, greentest eco 6 which is convenient for the public to detect the chemical composition of food by themselves. But the accuracy of some instruments is questionable, which is more likely to mislead the public.

A mother bought a Chinese household and fruit and vegetable detector with more than 800 yuan to detect nitrate components in fruits and vegetables. radioactive detection With the test results as a reference, she hoped to conduct food safety checks for her children. But she was skeptical about the accuracy of the test, so we came to test the reliability of the home test and teach you effective teaching methods to reduce the intake of pesticides and chemicals in fruits and vegetables.

According to mothers, tomatoes are one of the vegetables that often exceed the limit, and organic tomatoes are even higher than regular tomatoes. Therefore, this time we chose an organic tomato and a conventional tomato as test subjects, radiation detectors for sale and first tested them with the fruit and vegetable detectors in the respondents' homes. In one test, the Fruit and vegetable analyzer found that one organic tomato contained 95 mg/kg of nitrates.

Following the instructions of the fruit and vegetable detector, we first select the "tomato" option, then insert the instrument head into the tomato and press the "Start Test" button. In the same set of steps, we run five tests and take the average of the five results. The results showed that organic tomatoes contained 94.2 mg u002F kg of nitrate, while conventional tomatoes had 51.4 mg u002F kg of nitrate.

Then, using the same tomato samples, technicians separately extract tomato juice and put it into laboratory equipment for testing. The results showed that the nitrate content of organic tomatoes was 25mg/kg, while the nitrate content of ordinary tomatoes was 28.5 mg/kg, which was completely different from the detection results of fruits and vegetables. In addition to the huge difference in numerical values, laboratory tests have shown that organic tomatoes have lower nitrate levels than regular tomatoes.
