The invention discloses a method of identifying donkey-hide gelatins produced by different manufacturers in different regions. The method comprises the steps of carrying out sedimentation treatment on donkey-hide gelatins, carrying out microwave digestion treatment on sediment, rapidly determining a plurality of types of microelements in the donkey-hide gelatins by adopting an inductively coupled plasma-mass spectrum, establishing a standard fingerprint spectrum for the plurality of types of microelements in the donkey-hide gelatins and evaluating the effectiveness and the reliability of the established spectrum by adopting a vector similarity method. By using the method, reliable evidences can be provided for genuine donkey-hide gelatins of donkey-hide gelatin industries and the manufacturers in different regions.
