Identification method of nitrogen-containing compounds in Maotai

The invention provides an identification method of nitrogen-containing compounds in Maotai, and belongs to the technical field of analysis and detection. The identification method comprises: a step of extracting the nitrogen-containing compounds in Maotai, a step of using a gas chromatography-nitrogen phosphorus detector-mass spectrometry technology to detect and analyze the obtained nitrogen-containing compounds in Maotai, and a step of carrying out qualitative and quantitative analysis on the nitrogen-containing compounds. According to the invention, the headspace solid-phase micro-extraction is combined with the gas chromatography-nitrogen phosphorus detector-mass spectrometry technology to analyze the nitrogen-containing compounds in a liquor sample of Maotai, so that a qualitative and quantitative analysis method of the nitrogen-containing compounds in Maotai is formed. The identification method of the nitrogen-containing compounds in Maotai disclosed by the invention is simple and easy to operate and wide in applicability.
