Description

Technical Field

[0001] The invention relates to high-quality snail mucus and an extraction method thereof. Background Art

[0002] The mucus secreted by snails contains natural allantoin, calcium, glycolic acid, collagen, protein and vitamins, which are essential materials for making cosmetics.

[0003] The main components of snail mucus are:

[0004] 1. Collagen: Collagen is an important connective tissue component of the skin. Together with elastin, it forms a complete structure for the skin and has the effect of retaining moisture.

[0005] 2. Elastin: Elastin is the elastic protein that maintains skin tissue. As we age, the skin loses elasticity and wrinkles appear. Proper supplementation of elastin can prevent the early appearance of wrinkles and reduce the damage of ultraviolet rays to the skin.

[0006] 3. Allantoin: Allantoin effectively repairs scars and helps the skin fight free radicals. It has moisturizing, wound healing, anti-inflammatory, cell regeneration stimulation and soothing effects. It can be used as a skin softener and antioxidant.

[0007] 4. Glucuronic acid: Glucuronic acid can soften the viscous lipids on the surface of the skin's epidermis, which is beneficial for removing old keratin, accelerating cell regeneration, reducing skin wrinkles and scars, removing dull skin tone, lightening spots and resisting free radical damage to the skin.

[0008] Snail mucus is rich in nutrients and contains microorganisms. If it is not sterilized at high temperature, the extracted liquid is not easy to preserve and is prone to breeding bacteria and rotting. Even if preservatives are added, it cannot be stored for too long. The quality of the mucus will be destroyed after high temperature sterilization. If the mucus is made into dry powder, although it can solve the storage problem, the quality will be greatly reduced after it is dissolved into liquid, and the viscosity of the mucus will be lost.

[0009] It should be noted that the information disclosed in this background technology is only intended to increase the understanding of the overall background of the present invention and to understand the background and motivation of the inventor's invention conception, and should not be regarded as an admission or any form of implication that the information constitutes prior art already known to those skilled in the art. Summary of the invention

[0010] In order to overcome the above technical problems, the present invention provides a high-quality snail mucus and an extraction method thereof. The snail mucus extracted by the extraction method is of high quality and can maintain viscosity for a long time without being made into dry powder.

[0023] Furthermore, it also includes S8. testing the snail secretion liquid, and retaining those that meet the testing standards as qualified products.

[0024] Furthermore, in step S2, the feed includes one or more of fungus, okra and natto.

[0025] Furthermore, in step S3, the bactericide is benzalkonium chloride or benzalkonium bromide.

[0026] Furthermore, in step S1, fasting is performed for 2 days.

[0027] Furthermore, in step S3, the feed is fed for 2 days.

DETAILED DESCRIPTION

[0032] The present invention is described in detail below through specific examples, but the use and purpose of these exemplary implementation modes are only used to illustrate the present invention, and do not constitute any form of limitation on the actual protection scope of the present invention, nor limit the protection scope of the present invention to them.

[0033] Example 1

[0034] A method for extracting high-quality snail mucus in this embodiment comprises the following steps:

[0035] (1) Select healthy snails, preferably younger ones; place the selected snails in a clean place and fast for two days.

[0036] (2) From the third day, the snails are fed with special feed, which is rich in polysaccharides and mucins. For example, fungus, okra and / or natto, etc., can be made into a single or mixed feed. In this embodiment, the snails are fed with special feed from the third day, which is a feed made by mixing fungus, okra and natto in a weight ratio of 1:1:1.

[0037] (3) The snails that had been fed with the special feed for two days were taken out for surface disinfection and cleaning. The surface cleaning solution was a cleaning solution containing 0.1wt% of benzalkonium chloride. After cleaning, they were rinsed with clean water to remove the surface disinfectant.

[0038] (4) Then crack open the snail shell, remove the snail shell and impurities, take out the snail meat and place it in a clean container.

[0039] (5) Add saline solution into a clean container with a weight ratio of snail meat to saline of 1:2. Stir well and let it stand for 30 minutes to allow the snail to secrete more liquid. Stir for another 5 minutes and let it stand for another 30 minutes. Then filter out the snail secretion liquid with filter cloth.

[0040] (6) Repeat step (5) 1-3 times, and detect the solid content of the snail secretion liquid extracted each time. When the solid content is equal to or lower than 1.1wt%, the extraction step is not repeated. In this embodiment, step (5) is repeated 3 times. The solid content of the snail mucus extracted for the last time is reduced to 1.1wt%, so the extraction is not repeated, and the snail secretion liquids obtained in each time are mixed.

[0041] (7) The snail secretion liquid is treated with ultrasound for 5-30 minutes, and in this embodiment, 30 minutes is selected to kill the microorganisms in the snail secretion liquid, which is ultrasonic sterilization. In this way, after the above steps, the snail secretion liquid can maintain its viscosity for a long time without adding preservatives.

[0042] (8) The snail secretion fluid is then tested for the following test items: microbial limit, heavy metal content, solid content, and yield. Those that meet the test standards are retained as qualified products, and those that do not meet the test standards are discarded or used for other purposes.

[0043] Example 2 (comparative test)

[0044] In order to compare with Example 1, this comparative example also carried out conventional extraction: the collected snails were directly rinsed, the shells were knocked open, the snail shells and impurities were removed, the snail meat was taken out and placed in a clean container, and then directly extracted; the weight ratio of snail meat to physiological saline was 1:3; stirred evenly, allowed to stand for 30 min, stirred for another 5 min, allowed to stand for another 30 min, and then the snail secretion liquid was filtered out with a filter cloth.

[0045] Embodiment 3 (performance comparison test):

[0046] The snail secretion liquid prepared in Example 1 of the present invention was tested and compared with the snail secretion liquid prepared by the conventional method in Implementation 2 (comparative test). The results are shown in Table 1.

[0047] Table 1

[0048]

[0049]

[0050] The above test results show that the snail secretion liquid extracted by the present invention (Example 1) is significantly superior to the snail secretion liquid extracted by the conventional method (Example 2) in terms of both quality and yield.

[0051] The series of detailed descriptions listed above are only specific descriptions of feasible embodiments of the present invention. They are not intended to limit the scope of protection of the present invention. All equivalent embodiments or changes that do not deviate from the technical spirit of the present invention should be included in the scope of protection of the present invention.
