[0029] Method of brewing donkey-hide gelatin powder:

[0030] Method 1: Direct brewing

[0031] Pour an appropriate amount of donkey hide gelatin powder into the prepared container, slowly add warm or hot water while gently stirring with chopsticks or a stirring stick to gradually dissolve the donkey hide gelatin powder in the water until a uniform paste is formed. Continue stirring for about 1-2 minutes to ensure that all the powder is completely dissolved without lumps.

[0032] Method 2: Warm water pre-dissolution method

[0033] First, add a small amount of warm water (about 30ml) to the donkey-hide gelatin powder and stir it into a thick paste. Let it sit for a few minutes to help speed up the dissolution process. Then slowly add the remaining warm or hot water and continue stirring until it is uniform.

[0034] Method 3: Brewing with milk (suitable for people who don’t like the taste of pure water)

[0035] Prepare an appropriate amount of milk (such as 200ml), heat it to a suitable temperature (about 40-50℃), do not boil it, add the donkey-hide gelatin powder directly into the warm milk, stir it evenly and then drink it. This method can not only improve the taste, but also increase the intake of calcium and other nutrients.

[0036] A method for preparing donkey-hide gelatin powder, the specific steps of the method for preparing donkey-hide gelatin powder are as follows:

[0037] Step 1: selecting donkey-hide gelatin, red dates, milk powder, edible flavors, sweeteners, emulsifiers, wolfberry extract, licorice extract, peppermint oil, vitamin C and lactic acid bacteria by weight, drying the selected red dates using a drying device, and then crushing them into powder after drying;

[0038] Step 2: Crush the donkey-hide gelatin block and pour it into a container, add 10-12 times warm water, control the temperature of the warm water to 30-40 degrees Celsius, and stir evenly to form a thick gelatin solution;

[0039] Step 3: pour the prepared donkey-hide gelatin solution, red date powder, milk powder, wolfberry extract and licorice extract into a container in sequence, use a stirring device to mix and stir them for 30-40 seconds to make them evenly mixed, and then add edible flavors, peppermint oil, vitamin C and lactic acid bacteria after they are completely mixed, continue to stir for 1-2 minutes until they are completely mixed, and finally add sweeteners and emulsifiers until they are evenly mixed;

[0040] Step 4: Grind the mixed liquid using a grinding device. After grinding, sieve the mixed material through a fine mesh screen to remove larger particles to ensure the fineness and smoothness of the final product;

[0041] Step 5: Heat the mixed liquid at a low temperature, control the temperature of the heating device to 50-60 degrees Celsius, stir continuously while heating to avoid burning, until the mixture becomes a viscous solid, and finally dry the solid, crush and grind it into granules after drying, and finally pack it into bags.

[0042] The milk powder is skimmed milk powder, and the edible flavor is milk flavor or fruit flavor.

[0043] The sweetener is selected from sucrose, glucose syrup, and xylitol; the emulsifier is selected from lecithin or glyceryl monostearate.

[0044] The preparation steps of the wolfberry extract are as follows:

[0045] Select fresh, mature, mildew-free and insect-free wolfberry fruits as raw materials to ensure their good quality. Wash the wolfberry with clean water to remove surface dust and impurities, then place it in a well-ventilated environment to dry naturally or use low-temperature drying equipment (temperature not exceeding 40°C) for preliminary drying. Use a crusher to break the dried wolfberry fruits into small pieces so that the active ingredients are easier to dissolve in the subsequent extraction process. If it is necessary to further improve the extraction efficiency, the crushed wolfberry can be further crushed to an appropriate particle size (such as passing through a 20-40 mesh sieve), but be careful to avoid excessive crushing to cause loss of active ingredients. Add the crushed wolfberry to pure water in a certain ratio (such as 1:10, wolfberry: water), stir evenly and let it stand and soak for a period of time (usually 1-2 hours); place the soaking liquid in a stainless steel pot or other heat-resistant container, heat it to boiling and keep it in a slightly boiling state, and continue reflux extraction for 1-3 hours, stirring continuously during the period to promote the dissolution of the active ingredients. Use a multi-stage filtration device (such as gauze, filter paper, centrifuge, etc.) to remove the residue and collect the clarified extract;

[0046] The preparation steps of the licorice extract are as follows:

[0047] Choose licorice herbs from regular channels, preferably those with thick roots, brown color, solid texture, and no mold or insect infestation. Wash the licorice with clean water to remove surface dirt and impurities, then place it in a well-ventilated environment to dry naturally or use low-temperature drying equipment (temperature not exceeding 40°C) for preliminary drying. Use a crusher to break the dried licorice roots into small segments or slices so that the active ingredients can be more easily dissolved in the subsequent extraction process. If the extraction efficiency needs to be further improved, the crushed licorice can be further crushed to an appropriate particle size (such as passing through a 20-40 mesh sieve). According to different target ingredients, select appropriate concentration of edible alcohol (generally 50%-70%) as solvent, mix evenly in a certain ratio (such as 1:8, licorice: ethanol), seal and soak for 24-48 hours. During the soaking process, ultrasonic treatment (power of about 200W, frequency of about 40kHz) can be combined. Each treatment time is 15-30 minutes, and it is repeated 2-3 times to accelerate the release of effective ingredients. Similarly, the residue is removed through a multi-stage filtration device, the clarified extract is collected, and the ethanol is recovered by a rotary evaporator or reduced pressure distillation to obtain a concentrated solution.
