Rapid detection method of melamine liquid chromatography

Abstract

The invention discloses a rapid detection method of melamine liquid chromatography. The rapid detection method comprises a melamine extraction method and a liquid chromatography determination method. According to the detection method, an extraction method of the melamine is optimized, so that an accurate and reliable melamine liquid chromatography detection result meeting the national standard can be obtained without purification column and nitrogen blowing treatment in the detection process, the detection time of the melamine in the raw milk is remarkably shortened, the accuracy of the detection result is ensured, and the detection efficiency is improved. The method has positive effects on improving the production efficiency, shortening the production period and reducing the production cost, and is suitable for large-scale popularization and application.

Description

technical field [0001] The invention relates to the detection field of melamine, in particular to a rapid detection method of melamine liquid chromatography. Background technique [0002] Melamine is an organic ingredient with a nitrogen content of up to 66%. Excessive intake of melamine can cause kidney stones or lead to renal failure in infants and young children, resulting in serious food safety. Therefore, in the production process of dairy products, it is necessary to measure the melamine content of raw milk to prevent unqualified dairy products with excessive melamine content from entering the market and causing damage to the health of consumers. [0003] Existing melamine detection methods include high performance liquid phase method, potentiometric titration method and gas chromatography-mass spectrometry method, etc. Among them, in the national standard, the high performance liquid phase method is adopted for the detection of melamine. However, the high-performance...
