Problems solved by technology

Due to the different production periods of donkeys and the existence of poor parts of donkey hides, some donkey hides are prone to impermeable pickling, uneven pickling, and red skins, which will greatly shorten the storage time of donkey hides and affect the production of donkey-hide gelatin. Glue rate, and the quality of donkey-hide gelatin
Simultaneously these two kinds of donkey skin preservation methods also have the shortcoming of long pickling time, low production efficiency, high labor intensity of workers, and poor working environment

Abstract

The invention relates to a pretreatment method for traditional Chinese medicine donkey-hide gelatin's bulk drug donkey hide. The method comprises: 1) drum rolling saline water pickling; and 2) draining. The method provided by the invention employs the drum rolling saline water technique to replace the traditional salt spraying hide overlaying step, the pickling process also has a mechanical action, thus facilitating dissolution and penetration of the salt in the hide, the pickling can be more uniform, the pickling process is less than 5h, the pickling efficiency is high, and the pickling effect is good. High concentration salt water has a sterilization effect on the hide, thus effectively reducing the hide decay. In addition, based on drum rolling saline water, the method provided by the invention is also added with cooling washing and mechanical fleshing procedures. Cooling washing lowers the hide temperature, inhibits bacterial action, and also can wash off blood, feces and other sundries from the hide, thus being conducive to long-term preservation. Mechanical fleshing can remove grease from the flesh surface of the hide, and reduces the nutrient source of bacteria breeding. The method provided by the invention has high pickling efficiency and good pickling effect. The hide is clean and has a moderate salt content, thus facilitating subsequent processing.

Description

technical field [0001] The invention relates to a pretreatment method of donkey-hide gelatin raw materials, in particular to a method for treating donkey skin by pickling in salt water. Background technique [0002] Donkey-hide gelatin is a traditional traditional Chinese medicine with a long history. Its main raw material is donkey skin, and the quality of donkey-hide skin is the most important factor affecting the quality of donkey-hide gelatin. The donkey skins used to make donkey-hide gelatin mainly come from the skins peeled off from the animals after slaughtering equine animal donkeys. Due to reasons such as breeding, slaughter, and transportation, there is usually an interval between the fresh donkey skins being peeled off from the animals and the processing of donkey-hide gelatin. For a certain period of time, if the fresh donkey hide is not preserved in any way during this period of time, since there are many types of proteins that make up the fresh donkey hide, it ...
