Agricultural products such as fruits and vegetables are the most commonly purchased foods in our daily lives. In the purchase process, consumers are most worried about the quality and safety of agricultural products such as fruits and vegetables. In fact, everyone knows that pesticides will be sprayed during the production of fruits and vegetables, and pesticides are toxic chemicals. If they are not handled well, it is possible to have fruits and vegetables with excessive pesticide residues. Therefore, to ensure the quality and safety of agricultural products such as fruits and vegetables, one of the inevitable jobs is the detection of pesticide residues. The pesticide residue tester is a rapid detection instrument for pesticide residues. This new technology can not only ensure the quality and safety of agricultural products sold in the market, but also promote the standardization of production and the improvement of the quality of agricultural products such as fruits and vegetables.
There are many methods for detecting pesticides in fruits and vegetables, and the traditional methods of detection are cumbersome. The operation in fields, supermarkets, farmer's markets and other places is not strong. Taking apple as an example, the traditional fruit and vegetable drug residue detection step is generally required to be purified by solid phase extraction column after “crushing apple-homogenization-adding solvent extraction-extraction liquid. After purification and concentration, the sediment is removed by a filtering device. Then go to the liquid chromatograph or gas chromatograph and the chromatogram-mass spectrometer for detection - the results are issued. It takes at least 1-2 days to complete the entire inspection process to get the test results. This type of detection is not only time-consuming and labor-intensive, but also cost-effective, so it is not suitable for a wide range of promotion.
However, the pesticide residue tester can be used to determine pesticide residues such as fruits and vegetables, which can simplify many operation processes, and the instrument has low cost, fast detection speed, and can quickly obtain test results, so it is very suitable for pesticide residue detection in different places. At present, as people pay more and more attention to the quality and safety of agricultural products, how to improve the quality and safety of agricultural products such as fruits and vegetables has become an important goal of high-quality agricultural development. The use of pesticide residue testers to strengthen pesticide residue detection can not only strengthen supervision. Moreover, it can regulate all aspects of the production and circulation of agricultural products, and promote the continuous improvement of the quality and safety of agricultural products.
