Chicken-derived characteristic collagen peptide and application thereof in detection of collagen hydrolysate and products thereof

The invention discloses a chicken-derived characteristic collagen peptide and application thereof in detection of collagen hydrolysate and products thereof, which belong to the technical field of detection, and relate to a characteristic collagen peptide Asn-Gly-Leu-Hyp-Gly-Pro-Ile-Gly-Pro-Ala-Gly-Val-Arg of a chicken-derived component. Whether to contain the chicken-derived component is determined through detecting the characteristic collagen peptide. Specifically, pancreatin digestion is performed on protein components in a sample to dissociate characteristic collagen peptides, and then whether the characteristic collagen peptides are contained is detected by a liquid chromatograph-mass spectrometer to determine whether chicken-derived components are contained. The method has the advantages of strong characteristics, high sensitivity and simple operation, and can be used for determining the chicken-derived components in the collagen hydrolysate and products thereof. 一种鸡源的特征性胶原肽及在胶原水解物和其制品检测中的应用，属于检测技术领域。本发明
