Method for identifying production source of N-acetyl-D-glucosamine

The invention relates to the technical field of isotopes. More specifically, the invention relates to a method for identifying a production source of N-acetyl-D-glucosamine. The combustion-isotope mass spectrometry technology is used for determining the carbon isotope abundance value delta C to identify the production source of the N-acetyl-D-glucosamine, the method is convenient to operate andhigh in practicability, the source of the N-acetyl-D-glucosamine can be accurately identified, and the accuracy rate is 100%. 本发明涉及同位素技术领域，更具体地，本发明涉及一种鉴别N-乙酰-D-氨基葡萄糖生产来源的方法，其使用燃烧-同位素质谱技术测定碳同位素丰度值δC鉴定N-乙酰-D-氨基葡萄糖生产来源，该方法操作方便，可实施性强，可以准确对N-乙酰-D-氨基葡萄糖的来源进行鉴定，准确率为100％。
