Device and method for detecting pesticide residues in fruits and vegetables

Abstract

The invention relates to a device and a method for detecting pesticide residues in fruits and vegetables. The device comprises a detection device upper cover (1) and a detection device main body (2) connected to the detection device upper cover (1). The device is characterized in that the detection device main body (2) comprises a power supply module (3), a reagent storage module (4), a detected sample chamber (5), an input module (6), a detection module (7), a computing module (6), and an output module (9). The device is a portable detection device adopting an enzyme reagent method and can realizes the whole detection on pesticide residues in fruits and vegetables. The device has a high integrated level and realizes convenient and effective detection on pesticide residues in agricultural products such as fruits and vegetables outside of the laboratory.

Description

technical field [0001] The invention relates to a detection device, in particular to a detection device and a detection method for residual pesticides in fruits and vegetables. technical background [0002] In recent years, food safety has been paid more and more attention by people. With the development of agricultural technology, more and more pesticides are used in the production of fruits and vegetables. Due to the non-standard use of pesticides, the phenomenon of excessive use or abuse of pesticides in crops is becoming more and more serious, and the problem of pesticide residues caused by excessive use of pesticides will greatly affect people's health. At present, among the pesticides commonly used in my country, organophosphorus and carbamate pesticides account for more than 60% of the total amount of pesticides. The ability to decompose the neurotransmitter acetylcholine in the middle, so that the excessive accumulation of acetylcholine at the synapse makes a series...

Problems solved by technology

Due to the irregular use of pesticides, the phenomenon of excessive use or abuse of pesticides in crops is becoming more and more serious, and the problem of pesticide residues caused by excessive use of pesticides will greatly affect people's health

At present, among the pesticides commonly used in my country, organophosphorus and carbamate pesticides account for more than 60% of the total amount of pesticides. The ability to decompose the neurotransmitter acetylcholine in the middle, so that the excessive accumulation of acetylcholine at the synapse makes a series of nerves with acetylcholine as the transmission medium in an over-excited state, leading to nerve conduction dysfunction, resulting in inhibition and failure, causing symptoms of poisoning

[0003] At present, there are many detection methods for pesticide residues, but most of the detection equipment are expensive. Although the cost of the enzyme reagent method is low, the detection process has many steps and the process is cumbersome, which is not conducive to rapid on-site detection. Realized in one detection device, it will greatly improve the efficiency of enzyme reagent method detection
