Abstract

The invention discloses a method for processing a donkey-hide gelatin raw material donkey skins. The method includes the following steps: (1) steam heating; (2) hair pulling and hair picking; (3) scraping of excess meat; (4) rinsing; and (5) air drying, wherein the steam heating temperature in step (1) is 65-80 DEG C, and the steam heating time is 3-10 min; and the temperature of pulling and picking of hair from the donkey skins is 25-35 DEG C. The method for processing the donkey-hide gelatin raw material donkey skins allows the fresh donkey skins to be heated in a steam heating manner, so the hair removal rate can reach 99.0% or more; and inclination selection of a support and arrangement of a linear hollow-out stainless steel airing plate facilitate the removal of water from the donkeyskins and can shorten the drying time, so the obtained donkey skins are clean and tidy, and have no impurities, and prepared donkey-hide gelatin has good quality and good mouthfeel.

Description

technical field [0001] The invention relates to a method for processing donkey hide, a raw material of donkey-hide gelatin. Background technique [0002] Donkey-hide gelatin is a precious traditional Chinese medicine with a long history. Its main raw material is donkey skin, and the quality of donkey-hide skin will significantly affect the quality of donkey-hide gelatin. The donkey hides used in the production of donkey-hide gelatin mainly come from the skins peeled off from the slaughtered donkey bodies. In reality, there is usually a certain time interval for the fresh donkey skins peeled off from the donkey carcasses to enter the donkey-hide gelatin processing process. During this period, if If the fresh donkey hide is not preserved in any way, the donkey hide will be easily spoiled. [0003] At present, donkey hides are generally pretreated by drying or salting before preservation. The drying method generally refers to natural drying. This method takes a long time to d...
