Method for fast measuring melamine in food by anthraquinone-2-sodium sulfonate sensor

The invention belongs to the field of food detection, and particularly relates to a method for fast measuring melamine in a sample by an anthraquinone-2-sodium sulfonate sensor. The method comprises the following steps of: preparing a standard melamine solution; drawing a standard curve; preparing a sample to be measured; and detecting the sample. The method disclosed by the invention can be used for detecting whether melamine is contained in the food sample or not and the melamine content, has the advantages of real-time and fast detection, can complete the integral detection process within 30 minutes, achieve the minimal detection limit at 5.00*10M (0.6 microgram/millilitre) and bring about great convenience for the supervision and control of market food safety, and has the advantages of low detection cost, real-time and fast detection on food in market and production, and the like.
