Problems solved by technology

The main reason is that on the one hand, the awareness of the legal system is not strong; on the other hand, it is mainly because the existing fur identification methods are lagging behind, and it is impossible to accurately and easily distinguish donkey skin from horse, cow, and pig fur.
[0004] At present, the identification of donkey, horse, cow, and pig fur is mainly based on the identification of macroscopic properties, that is, according to the characteristics and experience of animal fur, the identification is carried out by direct observation with eyes. It is impossible to distinguish macroscopically
At present, it has been reported that the near-infrared method is used to identify animal fur species. Although this method is feasible to a certain extent, its operation is relatively cumbersome and requires professional equipment and operators, which leads to high detection costs and is not convenient for rapid identification and promotion. universal

experiment example 1

[0037] Experimental example 1 Microscopic observation of hair on various donkeys, horses, cattle and pigskin sheets

[0038] 1. Collection of hair samples from various breeds of donkeys, horses, cattle and pigs

[0039] In order to ensure the accuracy and reliability of sample collection information, the present invention divides according to the breeds of donkeys, horses, cattle and pigs respectively, and adopts the needle hairs of donkeys, horses, cattle and pigs from different regions, different varieties, different colors and different parts , Villi for surface and section observation.

[0040] For donkey hair, hair samples of donkeys were collected by species; the present invention collected donkeys from Dezhou, Guanzhong, Guangling, Biyang, Xinjiang, Jiami, Southwest, Qingyang, Jinnan, and North China. Donkey, Sichuan donkey, Huaibei donkey, Linxian donkey, Qinghai donkey, Subei donkey, Taihang donkey and other donkey breeds in China. Donkey hair samples are collected a...

Abstract

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.

Description

technical field [0001] The invention relates to a method for identifying animal fur types, in particular to a method for quickly identifying donkey skins, which belongs to the field of identification of donkey skins. Background technique [0002] Donkey-hide gelatin is a solid gelatin made from the dry or fresh skin of Equus asinus L., an equine animal donkey, which is decocted and concentrated. At the same time, donkey-hide gelatin is also a high-grade nutritional tonic, which is used for weak constitution, low immunity, daily health care and beauty. It has been used as a nutritional tonic for more than 3,000 years. [0003] The main raw material for the preparation of donkey-hide gelatin is donkey hide. At present, some unscrupulous manufacturers, driven by profit, mix some cowhide, horse hide, pig skin, etc. as the raw material of donkey-hide gelatin in the preparation process of donkey-hide gelatin. The main reasons are, on the one hand, weak awareness of the legal sys...
