Embodiment Construction

[0011] Below by embodiment the present invention is further described:

[0012] A kind of preparation method of freeze-dried donkey-hide gelatin, make according to the following steps:

[0013] (1) Raw material processing: immerse the donkey skin in clean water for about 2-3 days to soften it, take it out and scrape off the donkey hair, cut it into small pieces, wash it with clean water, put it in boiling water and cook for about a quarter of an hour, until the skin rolls up , take it out, put it into another covered pot, add water until the donkey skin is submerged, and cook until most of the gelatin is dissolved to obtain a thick gelatinous juice;

[0014] (2) Pre-freezing treatment: Dilute the thick glue to a concentration of 20% and put it into a special plate;

[0015] (3) Quick freezing: Put the diluted donkey-hide gelatin juice into a freezer at -35°C to -45°C for quick freezing, and the freezing time is 0.5 to 1 hour;

[0016] (4) Sublimation: Set the temperature of ...

Abstract

The invention discloses a preparing method for freeze-dried colla corii asini, and relates to the field of traditional Chinese medicine preparation. The freeze-dried colla corii asini is prepared through the process steps of raw material processing, processing before freezing, quick-freezing, sublimating, decomposition freeze-drying. The decomposition freeze-drying step is executed according to the requirements that quick-frozen colla corii asini is cut into blocks and then put in a vacuum bin to be dried for 1-2 h so that the water content of the colla corii asini blocks can be lower than 6%, wherein the vacuum degree is 35-70 Pa, the temperature of a heating plate is 30-45 DEG C, and the colla corii asini blocks are taken out to obtain the freeze-dried colla corii asini. By freeze-drying the colla corii asini in vacuum, it can be ensured that the colla corii asini is not secondarily polluted by air, and the product is sanitary; the colla corii asini is good in texture, quick-dissolving and convenient to carry and can be taken after mixing with mineral water; the problems that colla corii asini decocting is difficult, and colla corii asini has peculiar smell are solved; the preparing method lays a foundation for colla corii asini industry process technology heading for the global market.

Description

technical field [0001] The invention relates to the field of traditional Chinese medicine preparation, in particular to a preparation method of freeze-dried donkey-hide gelatin.
