Technical Field

[0001] The invention relates to the field of daily chemical essential oils, and in particular to a sleep-aiding essential oil composition containing white tea essential oil, and a preparation method and application thereof. Background Art

[0002] With the accelerated pace of life and increased work pressure in modern society, more and more people are facing the problem of sleep disorders. Long-term lack of sleep not only affects individual work efficiency and quality of life, but may also cause a variety of health problems, such as cardiovascular disease, decreased immune system function, and emotional instability. There are various sleep-aid products on the market, including pharmaceutical sleep-aid products, health products, etc., but the effects of these products are uneven. Pharmaceutical sleep-aid products are prone to cause drug resistance and dependence in the body, and are accompanied by a series of side effects; the effects of health products such as melatonin supplements vary from person to person, and the effect is not obvious for some people. Although essential oils are widely used as a natural therapy to relieve stress and promote sleep, most of the existing sleep-aid essential oils on the market have problems such as slow onset, short-lasting effect, and questionable safety. In view of the various shortcomings of existing sleep-aid products, especially the situation that the sleep-aiding effect of sleep-aid essential oils is not ideal, the development of a sleep-aid essential oil with fast onset, significant effect and high safety for use in daily chemical flavors has become an urgent problem to be solved in the industry. Summary of the invention

[0003] In order to obtain a fast-acting, effective and safe sleep-inducing essential oil, the present application provides a sleep-inducing essential oil composition containing white tea essential oil, as well as a preparation method and application. The present application uses white tea essential oil as the main component. White tea essential oil not only has a unique aroma, can create a tranquil atmosphere, and help people relax, but also contains natural active ingredients that help regulate the nervous system and accelerate entering a deep sleep state. In addition, the addition of auxiliary ingredients such as gardenia oil, camphor oil and white orchid oil further enhances the sleep-inducing effect, while giving the composition a richer aroma layer and enhancing the pleasure of use.

[0004] In the first aspect, the present application provides a sleep-aiding essential oil composition containing white tea essential oil, which adopts the following technical scheme: a sleep-aiding essential oil composition containing white tea essential oil, comprising the following raw materials in parts by weight: 30 to 50 parts of white tea essential oil, 1 to 5 parts of gardenia oil, 10 to 20 parts of camphor oil and 10 to 20 parts of white orchid oil.

[0005] In the above technical solution, white tea essential oil is rich in a variety of natural active ingredients, such as tea polyphenols, catechins, etc. These ingredients have been scientifically proven to have antioxidant, anti-inflammatory and sedative effects. Gardenia oil is known for its fresh and elegant aroma, which can effectively relieve tension and anxiety. Camphor oil is famous for its soothing and relaxing properties, which helps to reduce physical and mental stress and promote deep sleep. White orchid oil not only has a pleasant aroma, but also has the function of regulating the nervous system and balancing emotions, further enhancing the sleep-aiding effect.

[0006] The present application selects white tea essential oil as the main component of the sleep-aiding essential oil composition, and further adds camphor oil, white orchid oil and gardenia oil to the white tea essential oil to adjust the aroma and sleep-aiding effect of the sleep-aiding essential oil composition, so that the sleep-aiding essential oil composition has a unique aroma and significant sleep-aiding effect, and achieves a fast-acting and lasting sleep-aiding effect. First, the camphor oil and white orchid oil in the sleep-aiding essential oil composition can quickly promote body relaxation and shorten the time to fall asleep, and then the gardenia oil promotes the body's sleep preparation through further relaxation reactions, and the white tea essential oil can promote the body's absorption of the sleep-aiding essential oil composition in this process, so that the sleep-aiding essential oil composition can continue to play a calming and tranquilizing role, thereby helping the body quickly enter a deep sleep state and maintain high-quality sleep for a longer period of time.

[0007] Preferably, the preparation method of the white tea essential oil comprises the following steps: Step 1: Pick fresh white tea leaves and freeze them in an environment of -20 to -25°C for 16 to 18 hours; Step 2: crush the frozen white tea leaves into tea powder with a particle size of ≤0.5 mm; Step 3: withering the tea powder obtained in step 2 until the weight loss rate reaches 20% to 30%; Step 4: Add 3% to 5% by mass of citrus peel powder to the tea powder obtained in step 3, mix well, and then soak in 4 to 6 times the mass of enzyme solution, wherein the enzyme concentration in the enzyme solution is 0.5% to 1%, and shake at 45 to 50° C. for 30 to 40 minutes to obtain an enzyme solution; Step 5: extract white tea essential oil from the enzymatic hydrolyzate obtained in step 4 by distillation at 95-100° C., and collect the essential oil obtained by distillation, which is white tea essential oil.

[0008] In the above technical scheme, the present application freezes fresh white tea leaves in an environment of -20 to -25°C for 16 to 18 hours so that ice crystals can better pierce the cell wall, which is beneficial to the release of effective ingredients in the subsequent enzymatic hydrolysis process; in step 2, the frozen white tea leaves are crushed into tea powder with small particle size, which increases the contact area between the tea leaves and the enzyme and improves the enzymatic hydrolysis efficiency; the withering process in step 3 causes the tea leaves to lose moisture moderately and the aromatic substances in the tea leaves further accumulate; through enzymatic hydrolysis, the essential oil components in the white tea can be gently and effectively extracted, retaining more natural active ingredients and aroma substances, and by adding citrus peel powder for enzymatic hydrolysis, the active ingredients in the citrus peel powder can also cooperate with the components in the white tea essential oil to form complex aromatic substances, so that the finally obtained white tea essential oil has a better sleep-aiding effect.

[0009] Preferably, the enzyme in step 4 is a mixture of papain, cellulase and pectinase, and the mass ratio of papain, cellulase and pectinase is 1:(0.5-1):(0.5-1).

[0010] In the above technical scheme, the present application selects a mixture of papain, cellulase and pectinase as an enzymatic agent. Papain can effectively decompose the protein in tea leaves and release more amino acids and peptides, which play an important role in enhancing the aroma and sleep-inducing effect of white tea essential oil; cellulase and pectinase can decompose the cellulose and pectin in tea leaves, causing the cell walls of tea leaves to rupture and release more essential oil components, thereby improving the extraction efficiency of white tea essential oil.

[0011] Preferably, the withering in step 3 specifically comprises: placing the tea powder in a ventilated place for natural withering at 20° C.-25° C. until the weight loss rate reaches 20% to 30%.

[0012] In the above technical scheme, the present application chooses to naturally wither the tea powder, which can moderately dissipate the moisture of the tea without destroying the original aroma and active ingredients of the tea, so that the aromatic substances in the tea are further concentrated and refined, thereby improving the aroma quality and sleep-aiding effect of white tea essential oil.

[0013] Preferably, the invention further comprises 30 to 40 parts of grapefruit oil, 5 to 10 parts of sandalwood oil and 1 to 5 parts of sweet cumin oil.

[0014] In the above technical solution, grapefruit oil is well-known for its refreshing aroma and spirit-boosting effect, which can further enhance the pleasure and refreshing effect of the composition; sandalwood oil is known for its calm and lasting aroma, which helps stabilize emotions and prolong deep sleep time; sweet fennel oil has warm and soothing properties, which can relieve physical fatigue and promote full body relaxation. The addition of grapefruit oil, sandalwood oil and sweet fennel oil not only enriches the aroma level of the sleep-aiding essential oil composition, but also further enhances its sleep-aiding effect and the pleasure of use.

[0015] Preferably, it comprises 35.24 parts of white tea essential oil, 3.72 parts of gardenia oil, 11.35 parts of camphor oil, 12.83 parts of white orchid oil, 30.01 parts of grapefruit oil, 5.72 parts of sandalwood oil and 1.13 parts of sweet cumin oil.

[0016] In the above technical solution, the present application further adjusts the dosage ratio of each raw material so that the synergistic effect between the raw materials reaches the best state, thereby exerting the greatest sleep-aiding effect.

[0017] In a second aspect, the present application provides a method for preparing a sleep-aiding essential oil composition containing white tea essential oil, which adopts the following technical scheme: A preparation method of a sleep-aiding essential oil composition containing white tea essential oil comprises: mixing and stirring various raw materials to obtain the sleep-aiding essential oil composition containing white tea essential oil.

[0018] In the above technical scheme, the preparation method of the present application is simple and feasible, easy to industrialize and produce, and the obtained sleep-aiding essential oil composition has stable properties and high safety.

[0019] In a third aspect, the application of a sleep-aiding essential oil composition containing white tea essential oil provided in the present application adopts the following technical solution: The invention discloses an application of a sleep-aiding essential oil composition containing white tea essential oil in the preparation of daily chemical fragrance products.

[0020] In the above technical scheme, the sleep-aiding essential oil composition of the present application can be widely used in a variety of daily chemical fragrance products such as fireless aromatherapy, fragrance, spray and fragrance beads. These products can achieve significant sleep-aiding effects by adding the sleep-aiding essential oil composition, and can provide consumers with a more comfortable and pleasant sleep experience.
