Expected usage |
Ractopamine is a β-agonist drug, commonly known as clenbuterol, which can increase the carcass lean meat rate and has been widely added to feed. After eating animal foods containing ractopamine ( RAC ) residues, people will have symptoms such as dyspnea, nausea, vomiting, dizziness, headache, muscle tremor, palpitations, arrhythmia, and elevated blood pressure. In severe cases, it can endanger the reproductive system. The use of this drug has been explicitly banned in countries around the world. The conventional instrument detection method is limited to the use of laboratory professionals and the operation is cumbersome and inconvenient to carry, so it cannot meet the needs of rapid detection in large quantities in actual production. The ractopamine ( RAC ) rapid detection card has the characteristics of convenient carrying, simple operation, fast and high sensitivity, and is suitable for on-site large-scale sample detection. |
