preparation example Construction

[0014] At first, the present invention provides a kind of preparation method of earthworm extract, comprises the following steps:

[0015] S1, earthworms are pretreated;

[0016] In an environment of 5-20° C., the washed earthworms are placed in a slightly acidic aqueous solution with a pH of 5.5-6.8 for more than 2 hours. Specifically, clean water is used to rinse the earthworms to remove dust, soil and other pollutants on the surface of the earthworms. Then place the cleaned earthworms in a slightly acidic aqueous solution with a pH of 5.5-6.8. The slightly acidic environment has a certain stimulating effect on the earthworms, which in turn enables the earthworms to quickly eliminate impurities such as feces in the body, and then ensures that the subsequent earthworms can be fully sampled. material to reduce impurities in the extract.

[0017] Furthermore, the pH range used is represented as a slightly acidic environment, and if the acidity is too strong or the alkalinity ...

Embodiment 1

[0053] This embodiment provides an earthworm extract, which includes pyrroloquinoline quinone, hyaluronic acid, selenium, calcium, zinc, iron, magnesium, copper, manganese, and small molecules with a relative molecular mass below 3000. Peptides and free amino acids, and each liter of the earthworm extract contains 78 mg of pyrroloquinoline quinone, and each liter of the earthworm extract contains 90 mg of hyaluronic acid, 10 mg of selenium, and 1.005 grams of small Molecular peptides and 0.6 grams of free amino acids. Every 1000 grams of the earthworm extract contains 395 mg of calcium, 3.50 mg of zinc, 198 mg of magnesium, 1.20 mg of copper, 280 mg of iron and 0.92 mg of manganese.

[0054] The present embodiment also provides a preparation method of the above-mentioned earthworm extract:

[0055] S1, earthworms are pretreated;

[0056] Rinse the earthworms with clear water, then place the washed earthworms in a slightly acidic aqueous solution with pH=6 for 3 hours, then r...

Abstract

The invention relates to the field of natural extract, and particularly relates to an earthworm extract and a preparation method and a skin care product thereof. The earthworm extract includes methoxatin, hyaluronic acid, small molecule peptides with the relative molecular mass of 3000 or below and free amino acids, and the earthworm extract (per liter) contains 38.6-100.2 milligrams of methoxatin, 80-150 milligrams of hyaluronic acid, 1 gram or more than 1 gram of small molecule peptide with the relative molecular mass of 3000 or below and 0.7-1 gram of free amino acid. The earthworm extractcontains a variety of active ingredients, and the content of each active ingredient is high. The skin care product has excellent biochemical functions, such as anti-oxidation, anti-aging, cell repair,etc.

Description

technical field [0001] The invention relates to the field of natural extracts, and in particular to an earthworm extract, a preparation method thereof and a skin care product. Background technique [0002] Earthworm (earthworm) is a traditional Chinese medicine in my country, which has the functions of clearing heat, calming liver, relieving asthma and dredging collaterals. Indications hemiplegia, joint pain and so on. According to records, earthworms contain pyroxine, purine, choline, linoleic acid, various enzymes and vitamins. Most of the medicinal earthworms are decocted after cutting the abdomen and drying them, which not only easily loses and destroys some active ingredients, but also has a strong fishy smell, making it difficult to take. The protein content of fresh earthworms accounts for more than 20%, the average protein content in earthworm dry matter is 56.5%, and the highest can reach 71.0%; the oil content is 5% to 8%; earthworms are also rich in carotene and...
