[0016] In a preferred embodiment, in step S1, the whole dandelion plant picked in spring is selected, when the effective ingredients of dandelion are most abundant; after picking, the dandelion is subjected to low-temperature air-drying treatment to ensure that the moisture content is reduced to <10%; low-temperature air-drying can be carried out using low-temperature drying equipment, with the temperature controlled at 40-60°C and the drying time being about 12-24 hours to maximize the retention of the effective ingredients in the dandelion; precision crushing equipment, such as a high-speed grinder, is used to crush the whole dandelion plant into small particles of 1-3 mm to improve the extraction efficiency and ensure that the powder yield reaches 27% to 30%.
[0017] In a preferred embodiment, the step S2 specifically includes:
[0018] Cold water immersion and water extraction: Put the crushed dandelion fragments into distilled water and soak them for 10 hours at a solid-liquid ratio of 1:10 to reduce the damage of high temperature to heat-sensitive components;
[0019] Phased boiling extraction:
[0020] Phase 1: Release of flavonoids and chicoric acid;
[0021] The second stage: promoting the efficient dissolution of triterpenoid saponins;
[0022] The third stage: completely release other active ingredients;
[0023] Centrifugal separation: The extract is centrifuged at a speed of 3000-6000r / min for 5-20 minutes to separate the precipitate and remove impurities;
[0024] Concentration and drying: The extract is dried by microwave drying equipment, the temperature is set at 50-70°C, and the drying time is 20-30 minutes; the final dry powder is finely sieved and the particle size is controlled at 80 mesh.
[0025] In a preferred embodiment, in step S3, the particle size of the Poria powder is ensured to be 80 meshes to avoid the powder being too coarse or too fine, which affects the mixing uniformity.
[0026] In a preferred embodiment, in step S4, an electronic balance with an accuracy of 0.01 g is used for weighing to ensure accurate weighing; during the premixing process, uniform mixing is ensured to avoid local concentration.
[0027] In a preferred embodiment, in step S5, the rotation speed of the mixer is controlled at 100-300 rpm to ensure uniform mixing of the powders and avoid powder agglomeration caused by too high a rotation speed; during the mixing process, samples are taken every 15 minutes, and a particle size analyzer is used to detect the mixing uniformity to ensure that the mixing effect meets the requirements.
[0028] In a preferred embodiment, in step S6, the hardness of the capsule shell is controlled within 3-5 hardness units to ensure the filling effect and the integrity of the capsule; during the capsule filling process, the working status of the capsule filling machine is checked every 30 minutes to ensure uniform filling.
[0029] In a preferred embodiment, in step S7, the capsule filling speed is controlled at 100-200 capsules / minute to ensure that the filling speed matches the conveying speed of the capsule shell to avoid breakage or deformation of the capsule shell; after filling, the capsule is immediately sealed and packaged, and the sealing of the packaging bag is ensured to be above 95% to prevent moisture and contamination.
[0030] In a preferred embodiment, in step S8, during the quality inspection process, high performance liquid chromatography detection technology is used to ensure that the detection results are accurate and reliable, and the detection accuracy reaches ±0.5%; before the product is packaged, an appearance inspection is carried out to ensure that the product has no problems such as damage and deformation, and the inspection frequency reaches 1 capsule for every 1,000 capsules.

Ensure that the moisture content of the powder before filling is less than 10% to avoid agglomeration during capsule filling. The powder is treated with electrostatic dust removal to ensure that there are no impurities, fine powder or electrostatic adsorption to improve fluidity
[0046] S7: Capsule filling
[0047] Use an automatic capsule filling machine to ensure that each capsule is evenly filled with 0.5 grams of powder
[0048] S8: Quality control and testing are performed, after which the entire dandelion extract-based dietary supplement preparation process is completed
[0049] Each batch of dandelion extract is quality tested, with a focus on the content of key active ingredients such as chicoric acid, triterpenoid saponins, and flavonoids, to ensure that the content of active ingredients in each batch is stable and meets product standards.
[0050] Each batch of products must be tested for heavy metals (such as lead, cadmium, and mercury) and pesticide residues to ensure that the products meet food safety standards and do not contain pollutants that are harmful to the human body.
[0051] During the production process, it is necessary to ensure that dandelion extract is not contaminated by microorganisms. High-efficiency filtration, ultraviolet sterilization and other technologies can be used to reduce the growth of microorganisms and ensure that the final product meets hygiene standards.
[0052] In step S1, the whole plant of dandelion picked in spring (including flowers, stems, leaves, and roots) is selected, when the effective ingredients of dandelion are the most abundant. After picking, the dandelion is subjected to low-temperature air drying to ensure that the moisture content is reduced to <10%. Low-temperature air drying can be carried out using low-temperature drying equipment, with the temperature controlled at 40-60°C and the drying time of about 12-24 hours to maximize the retention of the effective ingredients in the dandelion. Use precision crushing equipment, such as a high-speed pulverizer, to crush the whole dandelion plant into small particles of 1-3mm to improve the extraction efficiency and ensure that the powder yield reaches 27% to 30%.

[0061] In step S3, the particle size of the Poria powder is ensured to be 80 meshes to avoid the powder being too coarse or too fine, which would affect the mixing uniformity.
[0062] In step S4, an electronic balance with an accuracy of 0.01 g should be used for weighing to ensure accurate weighing. During the premixing process, uniform mixing should be ensured to avoid local concentration.
[0063] In step S5, the speed of the mixer should be controlled at 100-300 rpm to ensure uniform mixing of the powders and avoid powder agglomeration caused by too high a speed. During the mixing process, samples should be taken every 15 minutes and the mixing uniformity should be tested using a particle size analyzer to ensure that the mixing effect meets the requirements.
