The invention discloses a method for quickly identifying
donkey skin. The method comprises the following steps of: (1) taking a hair sample from
animal fur to be detected; (2) observing the surface and scale of the obtained hair sample; and (3) determining that the fur to be detected is the
donkey skin when the surface and scale of the hair sample on the fur to be detected have the following characteristics: the hair surface is rough; and the scale of the hair is not distributed clearly, the scale has large
rake angle and good luster, and the scale is spinous, sheet-like or
spore-like, extends to the outer side of the dry hair and is not distributed uniformly. By utilizing the method, the
donkey skin is distinguished from other animal furs very accurately, the accuracy and reliability of the raw donkey skin material are ensured, and the animal furs such as horse skin, cattle skin and pigskin in a process of preparing donkey-hide
gelatin are prevented from being mixed. The method has the advantages of high accuracy, low detection cost, quickness, convenience and the like, is easy to operate, and is convenient to popularize and apply in reality.
