It is of great significance to strictly control the pesticide residue in the juice, further improve the quality and safety of the juice product, and establish a rapid, efficient, and accurate detection method. The methods used for the detection of pesticide residues in fruit juices include liquid chromatography-mass spectrometry, and biosensors, which are expensive. The former is not equipped in general laboratories, and the scope of use is not extensive; the latter still remains in research in China. At the development stage, but with the constant emergence of new technologies and new materials, after solving its problems of stability, accuracy, shelf life, etc., the full investment in the market is also just around the corner. It can be predicted that biosensors have broad application prospects in the analysis of pesticide residues as the performance becomes more mature and the variety continues to increase.
Through the determination of the Pesticide Residue Tester, the residual components of various pesticides in the juice are complex and the residual pesticide species are very likely. Therefore, accurate and effective detection of the residue requires further research and discussion: (1) Pretreatment process How to remove impurity interferences; (2) How to quickly and qualitatively determine the type of residual pesticides when testing; (3) How to better use existing instruments in the research of detection technology to improve the sensitivity and accuracy of analysis; (4) ) How to improve the timeliness and environmental friendliness of the entire testing process requires continuous exploration and innovation.
Juices are juice products made from fresh or frozen fruits as raw materials by physical methods such as pressing, centrifugation, extraction, etc., and generally refer to pure juice or 100% juice. In the production process of fruits and vegetables, in order to ensure its yield and quality, various types of pesticides are widely used, so juices inevitably contain pesticide residues. With the increase of health awareness, consumers put forward higher safety requirements for juice products, and the most important thing for juice safety is the safety of pesticide residues. Therefore, it is very important to be able to accurately and reliably determine the scientific analysis of pesticide residues in fruit juices. The quality and safety of fruit juices cannot be ignored. Pesticide residue detector is an important instrument for the detection of its residue.
