Objective To establish a method for the identification of fish-derived ingredients in fish collagen powder by high-resolution mass spectrometry. Methods The collagen powders was identified (peptides) by high resolution mass spectrometry combined with MaxQuant data analysis. Results Three of the four samples purchased from market were mixed with proteins from other species and other proteins in various degrees, only one of them was the pure fish-derived collagen. Conclusion This method identifies the ingredient sources of collagen successfully, and provides strong technical support for the market supervision.
