The present disclosure discloses a standard characteristic polypeptide sequence for quantitatively detecting casein glycomacropeptide in a polypeptide product by mass spectrometry, and belongs to the technical field of inspection and detection. According to the present disclosure, three polypeptides for quantitatively detecting the casein glycomacropeptide are obtained through screening, which have amino acid sequences shown in SEQ ID NO:1, SEQ ID NO:2 and SEQ ID NO:3 respectively, and are suitable for quantitatively analyzing the content of the casein glycomacropeptide in a sample to be detected. According to the present disclosure, accurate quantitative analysis of the casein glycomacropeptide is realized, and the polypeptide sequence can be used for determining whether the content of the casein glycomacropeptide in the product reaches a standard or not.
A method for detecting casein glycomacropeptide, wherein the method comprises detecting a polypeptide having the amino acid sequence set forth in any one of SEQ ID NO:1, SEQ ID NO:2 or SEQ ID NO:3 by mass spectrometry.
