Problems solved by technology

However, these drying methods are all carried out at a temperature above 0°C or higher, and the resulting product shrinks in size, hardens in texture, and is not easy to dissolve in water; some substances even oxidize, and most of the volatile components will be lost; Some heat-sensitive substances, such as proteins and vitamins, will be denatured; microorganisms will lose their biological activity, and the dried product will have a great difference in character and quality compared with before drying.

Embodiment 1

[0032] A method for preparing animal semen freeze-dried powder, which is prepared by freeze-drying fresh semen, including the steps of pre-freezing, sublimation drying and analysis drying. The specific operation steps are as follows:

[0033] (1) Aseptically collect fresh donkey semen to remove flocculent turbidity and put it into a material tray, the thickness of the semen is 3.0mm;

[0034] (2) Put the above-mentioned material tray with semen into the clapboard of the cold hydrazine of the vacuum freeze dryer, the temperature of the cold hydrazine of the vacuum freeze dryer drops to -40°C, the temperature of the divider drops to -30°C, and the temperature of the material material is at -40°C. Pre-freeze at -26°C for 6 hours;

[0035] (3) Take out the cold hydrazine from the material tray, turn on the vacuum pump, and sublimate and dry at a vacuum degree of 1.5 Pa. The temperature of the partition is 0° C., and the temperature of the material is -38° C. for 3 hours;

Embodiment 2

[0048] A method for preparing animal semen freeze-dried powder, which is prepared by freeze-drying fresh semen, including the steps of pre-freezing, sublimation drying and analysis drying. The specific operation steps are as follows:

[0049] (1) Aseptically collect fresh donkey semen to remove flocculent turbidity and put it into a material tray, the thickness of the semen is 4.0mm;

[0050] (2) Put the above-mentioned material tray with semen into the clapboard of the cold hydrazine of the vacuum freeze dryer, the temperature of the cold hydrazine of the vacuum freeze dryer drops to -50°C, the temperature of the clapboard drops to -40°C, and the temperature of the material material is at -50°C. Pre-freeze at -39°C for 5 hours;

[0051] (3) Take out the cold hydrazine from the material tray, turn on the vacuum pump, and sublimate and dry at a vacuum degree of 5 Pa. The temperature of the partition is 1° C., and the temperature of the material is -34° C. for 2 hours;

Abstract

The invention relates to a method for preparing animal semen freeze-dried powder, which is used for preparing by adopting freeze-dried fresh semen and comprises the steps of prefreezing, sublimation drying and analysis drying. The invention has the following advantages that: (1) protein, microorganisms and the like can not denature or lose biological activity; (2) the loss of certain volatile components in the matter is small; (3) the growth of microorganisms and the action of enzymes are prohibited, so that the original nature of the freeze-dried powder can be maintained; (4) the volume is almost unchanged, the original structure is maintained, and the phenomena of concentration and hardening do not occur; (5) the dried matter is loose, porous and spongy, the dissolution is quick and complete after water addition, and the original nature can be recovered immediately; (6) certain easily oxidized substances in vacuum are protected; and (7) more than 95-99% of water can be removed by drying, and the dried product can stored for a long time without deterioration.

Description

technical field [0001] The invention relates to a method for preparing animal semen, in particular to a method for preparing animal semen freeze-dried powder by freeze-drying fresh animal semen. Background technique [0002] As we all know, semen contains sperm, 95% of semen is water, the others are protein, fructose, prostaglandins, vitamins, phospholipids, etc., and minerals include calcium, potassium, phosphorus, magnesium, and zinc. Animal proteins are high-calorie foods. In addition, it also contains ascorbic acid (vitamin C), cholesterol, choline, blood group antigen, inositol, purine, pyrimidine, vitamin B12, etc. It is extremely rich in nutrients, and may also contain some magical substances that humans have not yet known. Laboratory conclusions, medical reports and many years of practice have all confirmed that the semen of humans and animals has no toxic side effects. In order to achieve the purpose of health care, the existing oral semen or so-called sperm swall...
