For example, the acetamiprid colloidal gold rapid test card applies the principle of competitive inhibition immunochromatography, in which the acetamiprid in the sample binds to the colloidal gold-labeled specific monoclonal antibody in the process of flow, and inhibits the binding of the antibody and the acetamiprid-BSA coupler on the detection line of the NC membrane. If the content of acetamiprid in the sample was greater than or equal to 0.01 mg/kg, no red band appeared on the detection line (T), and the result was positive; conversely, the detection line (T) showed a red band, and the result was negative.
2. Enzyme-linked immunosorbent assay (ELISA) kit method
Enzyme-linked immunosorbent assay (ELISA) kit method: antigen and antibody specifically bind to each other, and quantitatively analyze the results according to the shade of the color.
What are the main methods of rapid food safety testing
3. Portable instrumentation method
Portable instrumentation method: such as portable intelligent rapid food safety detector pesticide residue detector (spectrophotometer), ATP fluorescence detector, acid meter, meat moisture meter, conductivity meter, temperature and humidity meter, the center of the thermometer, the polarity of edible oil tester, Irradiance meter, etc.
What are the main methods of rapid food safety testing? Guangzhou Risen Biological Science and Technology Co. In fact, in addition to the above detection methods, there are other forms of rapid detection methods. Food safety rapid detection is a favorable tool for food safety regulators, the use of on-site rapid detection can be timely detection of suspicious problems, take appropriate measures, to protect food safety has an important significance.
