What is the poppy shell colloidal gold rapid detection card?

In food and beverage consumption, poppy shells are often used by criminals to make hot pot base, braised flavor, barbecue seasoning and other foods due to their strong concealment and ability to enhance appetite, posing a serious threat to consumers' health. In order to quickly identify such illegal additives, the poppy shell colloidal gold rapid detection card came into being.

So, what exactly is it? Simply put, this is a rapid detection product based on colloidal gold immunochromatography technology, which is mainly used for qualitative detection of poppy shell residues in food. The core principle is the use of colloidal gold-labeled specific antibodies. When a food sample contains poppy shell residues, the residual components will combine with the labeled antibodies to form a complex. During the chromatography process, the reaction occurs at the detection line and the quality control line through capillary action. Finally, the results are judged by observing the color development of the strips - if the detection line is colored, it indicates that there may be poppy shell residues in the sample.

Compared with traditional detection methods, its advantages are very prominent: the detection speed is fast, usually 10-15 minutes to produce results, without complex equipment and professional operation; the operation is convenient, just simply extract the sample, add buffer dropwise, and observe the strips with the naked eye; high sensitivity, can detect very low concentrations of poppy shell residues to avoid missed detection.

In practical applications, it is widely used in daily self-inspection of catering enterprises, rapid screening by market supervision departments, and control of raw materials in food processing enterprises. For example, hot pot restaurants and luwei shops can use it to detect whether the base material is illegally added to poppy shells. Regulatory authorities can screen suspicious foods on-site in night markets, farmers markets and other places to effectively curb the abuse of poppy shells in food.

It can be said that the poppy shell colloidal gold rapid detection card is not only the "golden eye" in the field of food safety testing, but also an important line of defense to protect the "tongue safety" of consumers, so that illegal additives have nowhere to hide and escort healthy eating.
