Pesticide residue detection in food/food

Rapid detection methods for pesticide residues in food

(1) Immune detection technology There are two types of immune detection techniques for pesticide residues: radioimmunoassay (RIA) and enzyme immunoassay (EIA). The basic principle of the two technologies is the same, that is, the antigen reacts with the antibody to form an antigen antibody complex. RIA technology uses radioactive isotopes as indicators and then uses γ Measurement by X-ray detector or scintillation counter γ Ray or β The radiation intensity of a ray. In EIA technology, biological enzymes are used as markers. The enzyme undergoes a specific reaction with the substrate, resulting in a color reaction between the product and another substance or a change in the UV absorbance value. The absorbance value of the substrate solution is measured using a spectrophotometer to calculate the concentration of the tested substance
