With the improvement of people's living standards, health has become the focus of people's attention. The health of the body is closely related to the safety of food, therefore, people have put forward higher requirements for the cultivation process of food. In the process of planting crops, pesticides and fertilizers are often required to control pests and diseases and increase yields. However, excessive use of pesticides and fertilizers can lead to the problem of pesticide residues in agricultural products.
The most common way to detect pesticide residues in agricultural products is to use a rapid detection instrument for pesticide residues. The rapid detection instrument for pesticide residues uses advanced detection technology to quickly and accurately detect pesticide residues in agricultural products. Compared with the traditional detection method, it has the advantages of simple operation, fast operation, high accuracy and high sensitivity, and provides strong technical support for the quality and safety supervision of agricultural products.
The working principle of the rapid detection instrument for pesticide residues is to use the enzyme inhibition rate method to detect organophosphorus pesticides and carbamate pesticides in agricultural products. When pesticide residues in a sample are too high, they inhibit cholinesterase activity, which affects the breakdown of choline in the sample. By measuring the change in color of the sample after the addition of enzymatic reagents and chromogenic agents, the inhibition rate of the sample can be calculated. Depending on the inhibition rate, the type and concentration of pesticide residues in the sample can be determined.
The use of rapid detection instruments for pesticide residues can greatly improve the efficiency and accuracy of pesticide residue detection in agricultural products. The instrument can not only be used for on-site testing in farmers' markets, supermarkets, restaurants and other places, but also for daily monitoring in the agricultural production process, helping farmers better control the use of pesticides and improving the quality and safety of agricultural products.
