What is the fenpropathrin colloidal gold rapid detection card?

Fenpromethrin is a commonly used pyrethroid insecticide in agricultural production. It has high-efficiency and broad-spectrum insecticidal effects and can effectively control pests on vegetables, fruit trees and other crops. However, excessive use may lead to excessive residues in agricultural products, which pose latent risks to human health. Therefore, rapid and accurate detection of fenpromethrin residues in food has become an important part of food safety supervision. Fenpromethrin Colloidal Gold Rapid Detection Card is a rapid detection product developed based on this demand. It realizes rapid screening of fenpromethrin residues in food through colloidal gold immunochromatography technology.

In principle, the core of the fenpropathrin colloidal gold rapid detection card is the immune reaction between the colloidal gold-labeled antibody and the fenpropathrin antigen. The detection card contains fenpropathrin antibodies labeled with colloidal gold. When the sample (such as vegetable extract, fruit homogenate, etc.) is added dropwise to the sample well, it will move along the chromatography strip. If the concentration of fenpromethrin in the sample reaches the detection limit, the antigen will bind to the colloidal gold-labeled antibody to form an antigen-antibody-colloidal gold complex; when it continues to move to the detection line (coated with a fenpromethrin antigen analog), the complex is captured by the detection line and combines with the detection line to form a red band; at the same time, the quality control line (coated with a colloidal gold antibody) will always develop color to ensure that the detection process is effective. By observing the color development of the detection line and the quality control line, it is possible to quickly determine whether the fenpromethrin in the sample exceeds the standard.

In the application scenario, the fenpromethrin colloidal gold rapid detection card is widely used for the rapid screening of various foods. For example, in the field of agricultural products, it can detect vegetables (such as vegetables, tomatoes), fruits (such as apples, strawberries), tea leaves, etc.; in the food processing process, raw materials (such as dehydrated vegetables, fruit juices) can be sampled; in market supervision, it can also be used as a rapid screening tool on site to detect latent risks in a timely manner. Whether it is the flow detection of grass-roots regulatory departments, or the self-inspection of raw materials of enterprises, or the rapid investigation of the market, this detection card can play an important role.

Compared with traditional detection methods (such as high-performance liquid chromatography, gas chromatography, etc.), the deltamethrin colloidal gold rapid detection card has significant advantages. Its detection time is extremely short, usually 10-15 minutes to produce results, greatly shortening the detection cycle; the operation method is simple, no professional equipment and complex pretreatment, ordinary personnel can get started after simple training; low cost, suitable for large-scale screening use; at the same time, its high sensitivity, can accurately identify low concentration residues, and the detection card itself is portable, can be used in a variety of scenarios outside the laboratory.

It can be said that the fenpromethrin colloidal gold rapid detection card is a typical representative of food safety rapid detection technology. With its efficient and convenient characteristics, it provides strong support for guarding the "safety on the tip of the tongue", allowing us to enjoy safe food with more confidence in our daily life.
