There are more and more types of pesticides and more complex brands. The Raman spectroscopy and mass spectrometry screening methods introduced next are new technologies that replace biochemical methods. Raman spectroscopy uses a Raman scatterometer for detection, which has the advantage of being fast, but the disadvantage is that the false positives are high, and the specificity is not as good as that of the mass spectrometry quick screening method. As for the mass job email list spectrometry quick screening method, it is a patented method developed by the Agricultural Drug Toxic Test Institute of the Agricultural Committee, and has obtained patents in many countries such as the European Union, the United States, Japan, and Taiwan. It is also a test method publicly recommended by the Food and Drug Administration of the Ministry of Health and Welfare . As long as each pesticide has a corresponding organic sensor, it can be detected, and the detection time of a single sample is as long as 10 minutes. More importantly, the inspection results are more accurate and correct, and it is the benchmark technology for pesticide inspection in the world. However, relatively, the cost of the instrument is very high, long-term investment is required, and the professionalism of the inspector is required. Taking medical applications in the era of epidemic prevention as an example, Raman spectroscopy is a good rapid screening reagent, while mass spectrometry screening is a PCR test with high accuracy and sensitivity.TNL Brand Studio Also because of the high cost of mass spectrometry rapid screening, except for agricultural centers, academic institutions or professional inspection companies, the willingness to invest in general access platforms is not high. The agricultural e-commerce platform "Nontoxic Farmer", which operates on the core concepts of non-toxicity, friendliness, and peace of mind, is the first agricultural product platform in Taiwan that has obtained the mass spectrometry rapid screening method of technology transfer from the National Institute of Drug and Poisoning. The agricultural product platform of "Product Inspection" uses the most rigorous attitude and determination to check the safety of agricultural products on the platform for consumers. When buying fruits and vegetables, in addition to confirming whether the manufacturer meets the national standards, it is also necessary to choose products that have passed the inspection in a scientific way, and wash and peel them before eating to reduce pesticide residues and ensure food safety.

It is not easy to check the safety of all fruits and vegetables! The Taipei Agricultural Products Transportation and Marketing Corporation (Bei Nong) alone can handle about 1,500 tons of vegetables in a single day. Taiwan eats so many fruits and vegetables every day. How does it manage? At present, the domestic agricultural production center adopts a random sampling method, and takes some samples from a large number of fruits and vegetables to test the pesticide residues. Sometimes the unqualified rate of pesticide residues can reach 10% . Even in 2021, the Consumer Protection Department of the Executive Yuan will sample online shopping. The results of pesticide residues in vegetable products are even more alarming, with a failure rate of 30%. One of the green onion job email list products has a pesticide exceeding the standard by 36 times . In 2022, the Consumer Foundation will randomly test imported strawberries and local strawberries. up to 50% . This kind of situation is really uncomfortable, and it is very necessary to carefully examine and check. So, what method is used to test the pesticide residues in fruits and vegetables? At present, the commonly used rapid detection methods for pesticides (quick screening methods) can be divided into biochemical methods, Raman spectroscopy, and mass spectrometry fast screening methods. The biochemical method with the longest history is currently the most common quick screening method in major markets and mass retailers in China. This method is fast and cheap, but it has low specificity for pesticides and can only detect more than 30 kinds of pesticides. There are more and more types of pesticides and more complex brands. The Raman spectroscopy and mass spectrometry screening methods introduced next are new technologies that replace biochemical methods. Raman spectroscopy uses a Raman scatterometer for detection, which has the advantage of being fast, but the disadvantage is that the false positives are high, and the specificity is not as good as that of the mass spectrometry quick screening method.
