Hemoglobin treating fluid, efficient bloodstain species identification method and application

The invention discloses a hemoglobin treating fluid, an efficient bloodstain species identification method and application, the hemoglobin treating fluid comprises the following components in parts by weight: 50-70 parts of 0.25% trypsin digestive juice and 50-70 parts of pure water, and the total amount of the hemoglobin treating fluid is 120 parts. The efficient bloodstain species identification method comprises the following steps: S1, taking a bloodstain sample, putting the bloodstain sample into a centrifugal tube, and then adding a hemoglobin treatment solution into the centrifugal tube to obtain a primary sample; s2, fully oscillating the centrifugal tube filled with the primary sample, soaking the blood mark sample in the centrifugal tube for 30 minutes in an environment of 37 DEG C, and oscillating again after soaking; s3, placing the centrifugal tube which is vibrated again on a high-speed centrifugal machine, and centrifuging for 5 minutes at the speed of 13000r/min; s4, 100 microliters of supernat
