What is the aflatoxin M1 colloidal gold quick test card?

Aflatoxin M1 (AFTM1) is the metabolite of aflatoxin B1 in animals. It is highly toxic and carcinogenic. It is especially easy to enter the human body through dairy products (such as milk, cheese), posing a serious threat to liver health. In order to effectively monitor the AFTM1 content in food and ensure the safety of consumers' diet, the aflatoxin M1 colloidal gold quick test card came into being and has become an important tool in the field of food safety testing.

This quick test card is essentially a rapid detection product based on colloidal gold immunochromatography technology. The core principle is to take advantage of the specific binding characteristics of antigens and antibodies: the colloidal gold-labeled antibody in the card competes with the AFTM1 in the sample to bind the antigen on the detection line. If the concentration of AFTM1 in the sample exceeds the detection limit, the colloidal gold marker cannot bind to the detection line, and only the quality control line develops color; conversely, the detection line will also develop color, and the content of AFTM1 in the sample will be judged by the color development results. The whole detection process does not require complicated equipment, just drop the sample into the sample hole after processing, and the result can be read in 10-15 minutes. The operation is simple and convenient, and ordinary staff can get started after simple training.

In the application scenario, the aflatoxin M1 colloidal gold quick test card is widely used in the acceptance of raw materials, production process monitoring, and rapid screening work of market supervision departments and third-party testing agencies in dairy production enterprises. It can help enterprises detect AFTM1 exceeding standards in raw materials or finished products in a timely manner and avoid substandard products from entering the market. At the same time, it can also provide fast and accurate data support for regulatory authorities to improve the efficiency of food safety risk prevention and control.

Compared with traditional detection methods (such as high performance liquid chromatography and mass spectrometry), the colloidal gold quick test card has significant advantages: the detection speed is fast, which greatly shortens the time from sampling to results; the operation cost is low, and expensive equipment and professional technicians are not required; it is highly portable and can be used flexibly in on-site or mobile testing. Although its detection accuracy is slightly lower than that of large instruments, it can meet the needs of rapid screening and play an irreplaceable role in the whole chain supervision of food safety "from farm to table".

With the increasing attention of consumers to food safety, the aflatoxin M1 colloidal gold quick test card is gradually becoming an essential testing tool for food production enterprises and regulatory departments due to its high efficiency and convenience. It not only escorts dairy safety, but also provides strong support for building a safer food environment.
