Problems solved by technology

Although this method well retains the nutritional and active ingredients of velvet antler and shortens the processing cycle of velvet antler, it does not solve the discomfort caused by the fishy smell of velvet velvet-dried powder itself.

Embodiment 1

[0016] 1) Cleaning process: under the condition of not damaging the appearance of raw materials, use 40 o Wash the deer antler with 2% alkaline water of about C.

[0017] 2) Peeling process: Take out the frozen velvet antler and burn it with an alcohol lamp to remove the hair, then scrape off the ashes of the velvet with a knife, and tear off the antler skin along the fiber direction of the velvet.

[0018] 3) Slicing process: proceed quickly at 4°C, and pick slices with a metal plate in an ice bath state, with a slice thickness of 1-6 mm.

[0019] 4) Freeze-drying process: first pre-cool the freeze-dryer to -56°C, then put the velvet slices that have been frozen at -30°C for 0.5 hours on the shelf of the freeze-dryer, and turn on the vacuum pump to make the freeze-dryer dry. The internal pressure drops. In the sublimation stage, the pressure is maintained at about 50Pa, and the temperature is continuously raised from -20°C to 0°C and kept constant for about 6 hours. The pr...

Embodiment 2

[0022] Cleaning, peeling, slicing and crushing process are the same as in Example 1, and the freeze-drying process of the present embodiment is:

[0023] Pre-cool the lyophilizer to -30°C, then put the antler slices that have been frozen at -40°C for 0.5 hours on the shelf of the lyophilizer, and turn on the vacuum pump to reduce the pressure in the lyophilizer. In the sublimation stage, the pressure is maintained at about 80Pa, and the temperature is continuously raised from -20°C to 0°C and kept constant for about 4 hours. The pressure in the desorption stage is maintained at about 50Pa, and the temperature rises from 10°C to 40°C and remains constant for about 3 hours.

Embodiment 3

[0025] Cleaning, peeling, slicing and crushing process are the same as in Example 1, and the freeze-drying process of the present embodiment is:

[0026] Pre-cool the lyophilizer to -45°C, then put the antler slices that have been frozen at -20°C for 1.5 hours on the shelf of the lyophilizer, and turn on the vacuum pump to reduce the pressure in the lyophilizer. In the sublimation stage, the pressure is maintained at about 60Pa, and the temperature is continuously raised from -20°C to 0°C and kept constant for about 5 hours. The pressure in the desorption stage is maintained at about 60Pa, and the temperature rises from 20°C to 40°C and remains constant for about 2 hours.

Abstract

The invention discloses a preparation method of a pilose antler pure powder. With fresh pilose antler as a raw material, the pilose antler pure powder is prepared through washing, peeling, slicing, freeze-drying and pulverizing processes; the freeze-drying process comprises two stages of sublimation and desorption; in the sublimation stage, the pressure intensity is 10-200 Pa, the water-removing cryo-temperature is lower than -20 DEG C, the shelf temperature linearly slowly rises along with the time from -20 DEG C to 0 DEG C, and the time is 4-7 h; in the desorption stage, the pressure is 10-100 Pa, the temperature is 30-40 DEG C, and the time is about 2-4 h. According to the preparation method of the pilose antler pure powder, freeze-drying is carried out under conditions of preferred slices, temperature, pressure and time, so as to obtain the pilose antler product having the advantages of being lower in moisture content, more complete in active component preservation, longer in storage time, more conducive to taking and absorption for human bodies; and at the same time, the fishy smell and fur and feather of the pilose antler are removed, so as to adapt to the taking demand of modern city crowds and improve the physiological activity and the use value of the pilose antler product.

Description

technical field [0001] The invention relates to the field of biotechnology, in particular to a preparation method of pure deer antler powder. Background technique [0002] Antler is the young antler on the head of vertebrate cervidae sika deer or red deer, which has not yet been ossified and densely grown with hair. There is blood circulation, strong metabolism, and rapid growth. Deer antler is warm in nature, sweet and salty in taste, and has the functions of invigorating the kidney, nourishing essence and strengthening tendons. It is a precious raw material of traditional Chinese medicine. Antler contains more than 20 kinds of amino acids, various hormones, superoxide dismutase (SOD) and polyamines, as well as phospholipids, polysaccharides, polypeptides, vitamin A, insulin-like growth factor (IGF-1), Growth-stimulating hormone-releasing factor (GHRF-6), calcium phosphate, chondroitin sulfate and many other bioactive factors have good health care and therapeutic function...
