What is the Vomitoxin Colloidal Gold Rapid Detection Card?

In the field of food safety testing, rapid screening of mycotoxins has always been an important part of safeguarding public health. Among them, vomitoxin (deoxynivalenol), as one of the common mycotoxins, widely contaminates wheat, corn, rice and other grains, which not only reduces the quality of food, but also may enter the human body through the food chain, causing health risks such as nausea, vomiting, and weakened immunity. In response to this problem, the vomitoxin colloidal gold rapid test card came into being, becoming a powerful tool for food companies, regulatory authorities and scientific research institutions to quickly screen for vomitoxins.

So, what exactly is the vomitoxin colloidal gold rapid test card? It is essentially a rapid detection test strip based on colloidal gold immunochromatography technology. Through the principle of antigen-antibody specific binding, qualitative or semi-quantitative detection of vomitoxin in the sample is realized. Its core structure usually includes sample pad, binding pad, reaction membrane (detection line and quality control line) and absorbent pad. During detection, only the sample (such as grain extract) needs to be dripped into the sample well, and the sample is moved on the test strip by capillary action. When encountering colloidal gold-labeled antibodies, if there is vomitoxin in the sample, it will compete with the labeled antibody to bind the antigen on the detection line, resulting in color development or color change of the detection line, so as to quickly judge the result.

Compared with traditional detection methods (such as high-performance liquid chromatography, gas chromatography, etc.), the vomit toxin colloidal gold rapid detection card has significant advantages: first, the detection speed is fast, the whole process usually only takes 10-20 minutes, which can meet the needs of on-site rapid screening; second, the operation is simple, no professional training is required, and ordinary personnel can complete it according to the instructions; third, the cost is low, no large-scale instruments and equipment are required, and it is suitable for rapid self-testing in grass-roots laboratories or enterprise production lines; fourth, the specificity is strong, which can accurately identify the target toxin and reduce false positive interference.

In the application scenario, the detection card is widely used for the rapid detection of vomit toxins in various kinds of grains and processed products (such as flour, corn flour, rice), feed, Chinese herbal For example, food manufacturers can screen grains before raw materials are put into storage to remove contaminated batches in time; catering companies can conduct random inspections of homemade food raw materials to reduce food safety risks; regulatory authorities can quickly detect problem products in market supervision to ensure consumers' "safety on the tip of the tongue".

With the increasing attention to food safety, the vomit toxin colloidal gold rapid detection card plays an increasingly important role in the food safety prevention and control system with its high efficiency, convenience and accuracy. It not only provides rapid response technical support for food quality and safety, but also provides a strong guarantee for promoting the whole process of supervision "from farmland to table".
