Description

Technical Field

[0001] The invention belongs to the technical field of edelweiss finished product extraction, and particularly relates to a method for extracting edelweiss aromatic essence. Background Art

[0002] Edelweiss, also known as fireweed, is a sacred flower distributed in the highlands of Asia and the mountains of Europe. It grows in inaccessible areas at an altitude of 1,800-3,000 meters. It is protected in many countries. Since 2010, it has been confirmed as a very important source of skin anti-aging in the cosmetics industry. In the Valais region of Switzerland, Edelweiss is being continuously developed to make the herb and its extracts available for commercial applications, where its ingredients can be used to propose new formulas after cell culture. The main active substances of the hydroalcoholic extract of Edelweiss are velvet acid A and velvet acid B. At the same time, Edelweiss is also rich in chlorogenic acid, 3,5-dicaffeoylquinic acid and quinic acid. The aromatic essence contained in Edelweiss can gently and deeply cleanse the skin, remove epidermal oils and substances in the pores, and relieve skin tension, making it soft and not tight.

[0003] The existing Edelweiss aromatic essence extraction method often has a low yield in practical applications. At the same time, due to the non-uniform standards of the preparation liquid, harmful impurities appear. With the continuous development of society, people's market demand for Edelweiss products has increased accordingly. The Edelweiss products currently on the market are far from meeting people's needs. For this reason, we propose a method for extracting Edelweiss aromatic essence. Summary of the invention

[0004] The object of the present invention is to provide a method for extracting edelweiss aromatic essence, so as to solve the problems in the above-mentioned background technology that the yield of the existing edelweiss aromatic essence extract is low and the quality of the prepared finished product is poor.

[0005] In order to achieve the above object, the present invention adopts the following technical scheme: the method for extracting the edelweiss aromatic essence is to use fresh edelweiss as raw material, and the extract is prepared through the following steps: raw material screening, raw material cleaning, water immersion disinfection, warm water detoxification, high temperature drying, low temperature agglomeration, petal grinding, crushing and screening, fine powder pulping, shaking and centrifuging, filtering and wall extraction, and packaging and storage, wherein the main operation flow of the above steps is as follows:

[0006] Raw material screening: screening fresh, pest-free and disease-free Edelweiss petals;

[0007] Raw material cleaning: removing the stamens and petals of the edelweiss selected in the above step, and soaking the edelweiss after petals removal in water at a low temperature of 5-15°C for 10-15 minutes;

[0008] Soaking and disinfection: Drain the soaked edelweiss petals and transfer them to the disinfected water for soaking;

[0009] Warm water detoxification: Take the Edelweiss petals out of the disinfectant and soak them in 40-45℃ distilled water for 10-30min;

[0010] High temperature drying: draining the edelweiss petals after the warm water detoxification step, and drying the residual moisture in the edelweiss petals through a retort box;

[0011] Low temperature agglomeration: the dried petals are quickly frozen with liquid nitrogen to form petal agglomerates;

[0012] Petal grinding: crush the edelweiss petals agglomerated in the above step through a fine grinder;

[0013] Crushing and screening: sieving the crushed edelweiss petal powder through a 45-mesh sieve to obtain edelweiss petal fine powder;

[0014] Preparation of fine powder pulp: the edelweiss petal fine powder prepared in the above step is mixed with water having a specific gravity 4-6 times that of the fine powder, and heated and stirred to prepare a preliminary raw pulp;

[0015] Shake and centrifuge: Mix the initial puree with water 0.5 times the weight of the fine powder and shake well for 5-7 days to obtain a mixed puree;

[0016] Filtration and wall extraction: The formed mixed puree is filtered through a 20-40 mesh filter, so that the cell wall or plant tissue agglomerates on the mixed puree are blocked and filtered, and the mixed puree that passes through the filter will be prepared into Edelweiss aromatic essence;

[0017] Packaging and storage: Put the prepared Edelweiss aromatic essence into a storage bottle for storage.

[0018] Furthermore, in the high-temperature drying step, the drying time in the retort box is 5-12 minutes.

[0019] Furthermore, in the immersion disinfection step, the disinfectant is lime water with a mass percentage concentration of 0.5-2%, and the edelweiss petals are placed flat and immersed in the disinfectant for 10-15 minutes.

[0020] Furthermore, in the low-temperature agglomeration step, the outer side of the Edelweiss petals is wrapped with tin foil, and the tin foil wrapping the Edelweiss petals is immersed in liquid nitrogen for 12-15 seconds until the free water in the Edelweiss petals is frozen, thereby ensuring that the residual cell fluid is sealed, thereby retaining the active ingredients in the rose petals and forming Edelweiss petal agglomerates.

[0021] Furthermore, in the crushing and screening step, the powder remaining after screening and blocking needs to be ground and screened for the second time, and the remaining blocking fragments after the second grinding and screening will no longer be used, but will be placed in a processing box. The powder after the second grinding and screening can be directly mixed into the Edelweiss petal fine powder.

[0022] Furthermore, in the fine powder pulping step, the edelweiss petal fine powder and water with a specific gravity 4-6 times that of the fine powder are placed in a reactor at the same time, and the temperature of the reactor is raised to 75°C, and the mixed liquid is stirred for 30-50 minutes by a stirring device on the reactor at a speed of 300-500rpm.

[0023] Furthermore, in the shaking and centrifuging step, the preliminary puree mixture is placed in a sealed storage tank, and the storage tank is placed on a low-speed homogenizer at 4000 rpm for homogenization and stirring.

[0024] Furthermore, in the filtering and wall removal step, impurities that have not been filtered by the mixed slurry filter will be directly cleaned.

[0025] Furthermore, in the packaging and storage step, the finished edelweiss fragrance essence is placed in a dark-colored storage bottle that is protected from light.

[0026] Furthermore, in the packaging and storage step, the edelweiss aromatic essence placed in the storage bottle is refrigerated at low temperature.

[0027] Compared with the prior art, the present invention has the following beneficial effects:

[0028] 1. The method for extracting the edelweiss aromatic essence proposed by the present invention has a high yield rate, and through the three-layer disinfection and sterilization steps of water immersion disinfection, high-temperature drying and low-temperature agglomeration, it avoids the situation where residual bacteria on the petals and leaves of edelweiss are inconvenient to clean, thereby ensuring the quality of the essence, and through multi-step filtration, it avoids the situation where cellular impurities affect the fragrance of the petal essence.

[0029] 2. The high yield rate of Edelweiss aromatic essence extraction avoids the traditional coarse cloth extraction method that affects the aromatic smell of the essence, making the essence extraction purer and reducing the allergic reaction caused by impurities in the aromatic essence.
