Embodiment 1

[0035] A preparation method of donkey placenta extract, specifically as follows:

[0036] Wash the donkey placenta with water to remove some surface impurities, then dry the washed donkey placenta in a centrifuge at room temperature for 1 hour, and then dry it in an oven at 40-60°C to obtain a donkey placenta with a moisture content of 21%. The dried donkey placenta is pulverized with a pulverizer, and passed through a 20-mesh standard sieve to obtain donkey placenta powder; the donkey placenta powder and water are mixed in a mixer, then protease is added to the mixer, and the mixer is set to frequency Heating to 45°C in a 40KHz ultrasonic equipment for 0.5h of enzymolysis reaction to obtain the enzymolysis product, wherein the mass ratio of donkey placenta powder, water and protease is 1:5:0.5, and the enzymolysis product is used with a concentration of 90%. Adjust the pH value to 4.5 with L-malic acid, then refrigerate the enzymatic hydrolyzate at 0-8°C for 48 hours until th...

Embodiment 2

[0038] A preparation method of donkey placenta extract, specifically as follows:

[0039] Wash the donkey placenta with water to remove some surface impurities, then dry the washed donkey placenta in a centrifuge at room temperature for 1 hour, and then dry it in an oven at 40-60°C to obtain a donkey placenta with a moisture content of 24%. The dried donkey placenta is pulverized with a pulverizer, and passed through a 30-mesh standard sieve to obtain donkey placenta powder; the donkey placenta powder and water are mixed in a mixer, then protease is added to the mixer, and the mixer is set to frequency Heating to 50°C in a 40KHz ultrasonic device for 1 hour of enzymolysis reaction to obtain an enzymolysis product, wherein the mass ratio of donkey placenta powder, water and protease is 1:6:0.8; Adjust the pH value to 4.0 with L-malic acid, then refrigerate the enzymatic hydrolyzate at 0-8°C for 72 hours until the enzymatic hydrolyzate is separated, draw the supernatant, and fil...

Embodiment 3

[0041] A preparation method of donkey placenta extract, specifically as follows:

[0042]Wash the donkey placenta with water to remove some surface impurities, then dry the washed donkey placenta in a centrifuge at room temperature for 1 hour, and then dry it in an oven at 40-60°C to obtain a donkey placenta with a moisture content of 25%. The dried donkey placenta is pulverized with a pulverizer, and passed through a 40-mesh standard sieve to obtain donkey placenta powder; the donkey placenta powder and water are mixed in a mixer, then protease is added to the mixer, and the mixer is set to frequency Heating to 40°C in a 50KHz ultrasonic equipment for 40 minutes to obtain the enzymolysis product, wherein the mass ratio of donkey placenta powder, water and protease is 1:7:0.9; Adjust the pH value to 5.0 with L-malic acid, and then refrigerate the enzymatic hydrolyzate at 0-8°C for 96 hours until the enzymatic hydrolyzate is layered, draw the supernatant, and filter it with a f...

Abstract

The invention discloses a donkey placenta extract and a preparation method thereof. The donkey placenta extract is prepared in the steps that a smashed donkey placenta is subjected to ultrasonic enzymatic hydrolysis under the action of protease, then the pH value of the product is adjusted, the product is refrigerated and subjected to standing, and then fine filtration is conducted. The preparation method specially includes the following steps that firstly, the dried donkey placenta is smashed to obtain donkey placenta powder; secondly, the donkey placenta powder and water are mixed, then theprotease is added for ultrasonic enzymatic hydrolysis, and an enzymatic hydrolysis product is obtained; thirdly, the pH value of the enzymatic hydrolysis product is adjusted to be 4-6, then the enzymatic hydrolysis product is refrigerated and subjected to standing, so that the enzymatic hydrolysis product is layered, supernate is absorbed, filtering is conducted to obtain the donkey placenta extract, and the donkey placenta extract is sealed and stored. The donkey placenta extract prepared through the method contains a series of bioactive substances and has the effects of maintaining beauty and resisting aging. The preparation method of the donkey placenta extract is simple and feasible and low in production cost, and large-scale production is easy to achieve.

Description

technical field [0001] The invention belongs to the technical field of health products. More specifically, it relates to a donkey placenta extract and a preparation method thereof. Background technique [0002] The placenta is a transitional organ for exchanging substances between the mother and the child formed by the combination of the embryonic membrane and the maternal endometrium during pregnancy in mammals and mammals. It is composed of amniotic membrane, phyllodes chorion and decidual membrane. Because of its special barrier function and endocrine function, people have paid attention to it since ancient times. Human placenta is also known as "Ziheche". "Compendium of Materia Medica" claims that it has the functions of "soothing the nerves and nourishing blood, nourishing qi, benefiting essence, detoxifying, and nourishing blood". Those who take it will have clear ears and eyes, black beard, prolong life, and have the power to win the good fortune." In recent years,...
