Rapid pesticide residue detection system and detection method

Abstract

The invention belongs to the technical field of pesticide detection, and discloses a rapid pesticide residue detection system and detection method. The rapid pesticide residue detection system comprises a sample collection module, a sample processing module, a sample detection module, a detection result acquisition module, a detection result identification module, a central processing and control module, a data transmission module, a network server module, a voice broadcast module and a man-machine interaction module. Through the sample collection module and the sample processing module, samples can be quantitatively collected and processed, the workload of picking, processing and the like of workers is reduced, meanwhile, through the network server module, a detection end and a network end can be integrated, the release time of detection data is shortened, the timeliness and the action of data are improved, vegetable safety big data is formed, large-scale conversion of achievements is realized, the quality safety of food products is further guaranteed, the domestic and international competitiveness of food is improved, and sustainable development is promoted.

Description

Technical field [0001] The present invention belongs to the field of pesticide testing, and more particularly to a rapid detection system and detection method of pesticide residue. Background technique [0002] Current: Vegetables and fruits contain vitamins necessary for human body, people eat vegetables and fruits are one of the key ways to obtain these vitamins. However, in the process of planting and growth in vegetables and fruits, in order to prevent the invasion of pests and diseases, adding pesticides is an indispensable step. The safety degradation period of the pesticide usually applied is 14-28 days after the spray, but some agricultural products have not been completely degraded by pesticides, so there is often a problem with pesticide residue. [0003] At present, within a professional agricultural disabilities identification body, the method of accurately determines the type and quantity of pesticide residues is usually gas chromatography-mass spectrometry, but its ...

AI Technical Summary

Problems solved by technology

[0003] At present, in professional pesticide residue identification institutions, the method that can accurately determine the type and quantity of pesticide residues is usually gas chromatography-mass spectrometry, but the equipment is expensive, the sample preparation process is complicated, and the detection cycle is long, so it is difficult to achieve rapid detection

The enzyme inhibition method is added to the national standard for rapid detection, but the accuracy is low and is greatly affected by many factors, such as enzyme activity, instrument differences, etc.

In addition, there are methods such as immunological rapid detection method and biosensor method, but they also have problems such as low accuracy, long cycle time, and high cost, and cannot be used for rapid nondestructive detection in real life.

[0004] Through the above analysis, the problems and defects of the existing technology are: the existing technology has the problems of expensive equipment, complicated sample preparation process, long detection cycle, and difficult to achieve rapid detection.
