Embodiment Construction

[0011] The preparation process of donkey placenta freeze-dried powder of the present invention will be further described through examples below.

[0012] 1. Preparation of donkey placenta freeze-dried powder by liquid nitrogen freeze-grinding method

[0013] Pre-freeze the fresh donkey placenta in a -10°C refrigerator to form a frozen donkey placenta; place the frozen donkey placenta in a microtome to slice, and cut into thin slices with a length of about 0.5-1cm, a width of 0.2-0.5cm, and a thickness of about 0.2-0.5cm; Freeze the thin slices in liquid nitrogen for 2 minutes, and then quickly put them into a frozen mixing ball mill to grind them into a homogenate (about 60-90s), then place the homogenate in a clean petri dish; put the donkey placenta homogenate into a petri dish Put it into the cold trap of a freeze dryer, and freeze it at the temperature of the cold trap at -56°C for 8 hours; then put the culture dish containing the frozen donkey placenta homogenate on the d...

Abstract

The invention discloses a process for preparing donkey placenta freeze-dried powder by using a liquid nitrogen freezing and grinding method. The process comprises the steps of pre-freezing fresh donkey placenta at -10 to 0 DEG C so as to form frozen donkey placenta, then slicing the donkey placenta, and firstly freezing the donkey placenta slices in liquid nitrogen and then putting into a freezingmixed ball mill for grinding into homogenate; after that, placing the homogenate in a cold trap of a freeze dryer, controlling the temperature of the cold trap and carrying out freeze-drying to obtain freeze-dried donkey placenta; then, ultra-finely grinding the freeze-dried donkey placenta to obtain donkey placenta powder with uniform plasmid, packaging, sealing, and then carrying out low-dose transient irradiation by using Co60-electron beams to obtain the donkey placenta freeze-dried powder. After the process is adopted, the donkey placenta tissues can be rapidly and effectively ground within a very short time by using the liquid nitrogen freezing and grinding method, and biomacromolecules of the donkey placenta tissues are fully released in a solution, so that the natural activity ofthe biomacromolecules is better maintained, and the unique color of the donkey placenta is maintained; the donkey placenta freeze-dried powder containing rich nutritional ingredients can be obtained,and the production efficiency and the product yield are increased.

Description

technical field [0001] The invention relates to a preparation method of donkey placenta freeze-dried powder, in particular to a process for preparing donkey placenta freeze-dried powder by using a liquid nitrogen freeze-grinding method, and belongs to the technical field of medicine and health care products. Background technique [0002] The placenta is a special tissue that supplies nutrients to the fetus and allows the embryo to grow during pregnancy in mammalian viviparous animals. The placenta has been used as a tonic in my country for more than 1,000 years. In the "Compendium of Materia Medica", the placenta is called "Ziheche", which has the functions of "relief and nourishing blood, nourishing qi, replenishing essence, detoxifying, and nourishing blood". Modern research has found that the proteins, sugars, trace elements, estrogens, cytokines, and peptides contained in placental tissue can improve female endocrine regulation, promote cell division and proliferation, a...
