Description

Technical Field

[0001] The present application relates to the field of aromatherapy, and in particular, to a dried flower color-locking aromatherapy and a preparation method thereof. Background Art

[0002] With the continuous improvement of modern people's cognitive level and quality of life, people often hope to keep a kind of aromatic smell that is beneficial to the human body in their homes; aromatherapy is the plant essence extracted from the fragrant substances, which is often called plant hormones. Among them, the extracted aromatherapy has the effects of purifying the air, removing odors, sterilizing and removing mites. By adding aromatherapy to the diffuser, the aroma of aromatherapy can be diffused to every corner to achieve the effect of purifying the air. At the same time, some aromatherapy essential oils can also clean and purify the respiratory system, relieve respiratory discomfort, and the smell of aromatherapy can improve people's mood.

[0003] There are also aromatherapy bottles on the market that add dried flower structures, but the dried flowers are not realistic enough because the color of fresh flowers is difficult to preserve during the drying process. Even if the flowers are treated with color protectants and vacuum freeze-dried to retain the original color of the flowers to the maximum extent, long-term contact with air and exposure to ultraviolet rays will inevitably cause them to fade, corrode, and lose a lot of fragrance, greatly reducing their ornamental and decorative values, and even causing some unpredictable damage. Therefore, the color of dried flowers has become an important indicator to measure the quality of dried flower color-locking aromatherapy. Summary of the invention

[0004] In order to maintain the beauty of dried flower color-locking aromatherapy comparable to that of real flowers and maintain a unique aroma atmosphere, the present application provides a dried flower color-locking aromatherapy and a preparation method thereof.

[0005] In the first aspect, the present application provides a dried flower color-locking aromatherapy, which adopts the following technical solution: A dried flower color-locking aromatherapy comprises the following components in parts by weight: a transparent glass bottle, liquid aromatherapy and dried flowers, wherein the liquid aromatherapy is arranged in the transparent glass bottle, and the dried flowers are immersed in the liquid aromatherapy, wherein the liquid aromatherapy comprises the following parts by weight: 50-65 parts of dipropylene glycol methyl ether, 5-8 parts of benzalkonium chloride, 10-12 parts of deionized water, 12-18 parts of a color-locking composition, and the color-locking composition includes ethylene glycol stearate, sodium carboxymethyl cellulose and essence.

[0006] By adopting the above technical scheme, the lubricity and permeability of ethylene glycol stearate can penetrate into the molecules of dried flowers, so that the essence in the color-locking composition can contact the dried flowers, so that the dried flowers have antioxidant and rich aroma, and then form a film protection on the surface of the dried flowers through sodium carboxymethyl cellulose to prevent ultraviolet radiation, damage and discoloration. Dipropylene glycol methyl ether has good solubility and surface tension, which keeps the liquid aromatherapy ingredients stable, and then benzalkonium chloride is added to maintain the antibacterial properties of the solution, prevent bacteria and fungi from breeding, and then damage the dried flowers, avoid corrosion and fading of the dried flowers, and mix benzalkonium chloride and the color-locking composition to enhance the anti-mildew properties of the dried flowers. Then, specially treated dried flowers are placed in the liquid aromatherapy. When the dried flowers absorb the color-locking components, the color becomes brighter and the appearance is richer, giving people a more vivid and easier to identify aromatherapy visually. As a result, the dried flowers adjust the color projection by moisturizing, anti-oxidation, and film protective layer.

[0007] In a specific embodiment, the mass ratio of ethylene glycol stearate, sodium carboxymethyl cellulose and flavor is (5-8):(2-4):1.

[0008] By adopting the above technical scheme and the mass ratio of the color-locking composition disclosed in the present application, the color of the dried flowers is brighter and the storage time is longer; if too little ethylene glycol stearate is added, the color of the dried flowers is not fresh enough and the color storage time is shortened; if too little sodium carboxymethyl cellulose is added, the color is not realistic enough, the pigment is too concentrated, and the original color is lost, and the dried flowers are more easily damaged, the ornamental value is poor, and the storage time is shorter.

[0009] In a specific embodiment, the essence is an extract of a plant of the same genus as the dried flower.

[0010] By adopting the above technical solution, the dried flowers and color-locking components of the same plant can be used to restore the original color of the dried flowers to the greatest extent, making the color-developing carotene in the fresh flowers richer and the color-locking effect better.

[0011] In a specific embodiment, the volume ratio of the dry flowers to the liquid aromatherapy is: 1:(10-16).

[0012] Keep the dried flowers in contact with liquid aromatherapy at all times to prevent them from being exposed to the air for a long time, which may cause corrosion or damage to the dried flowers, and to make it easier to protect their color.

[0013] In a specific embodiment, the preparation method of the dried flowers comprises: (1) a fresh-keeping treatment step: spraying the freshly picked flowers with 5-10° C. water, and then putting them into a fresh-keeping bag with ventilation holes; (2) a microwave heating step: placing the fresh Camellia chrysantha flowers in a microwave drying oven, heating them for 45-60 seconds at a microwave power of 800-1000 W, taking them out, cooling them to 28-30° C., and repeating the above step (2) 3-4 times to obtain the primary dried flower product.

[0014] By preparing dried flowers using microwaves, the original color of the flowers is retained to the greatest extent possible, and the pigment is better preserved.

[0015] In a second aspect, the present application provides a method for preparing a dried flower color-locking aromatherapy, using the following technical solution: A method for preparing a dried flower color-locking aromatherapy comprises the following steps: (1) adding dipropylene glycol methyl ether, benzalkonium chloride, a color-locking composition, and deionized water in sequence at room temperature, mixing and stirring to obtain a mixture; (2) stirring the mixture in (1) uniformly and aging it to obtain an aged mixture; then freezing the aged mixture and filtering it; (3) adding the processed dried flowers respectively and bottling to obtain the dried flower color-locking aromatherapy.

[0016] The aging process is to seal and stand the container at a temperature of 18-25°C for 16-36 hours.

[0017] The freezing temperature in (2) is -5-0°C.

[0018] In summary, the present application includes at least one of the following beneficial technical effects: 1. Through the lubricity and permeability of ethylene glycol stearate, it can penetrate into the molecules of dried flowers, so that the essence in the color-locking composition can contact the dried flowers, making the dried flowers have antioxidant and rich aroma. Then, sodium carboxymethyl cellulose forms a protective film on the surface of the dried flowers to prevent ultraviolet radiation, damage and discoloration. Dipropylene glycol methyl ether has good solubility and surface tension, which keeps the liquid aromatherapy ingredients stable. Then, benzalkonium chloride is added to maintain the antibacterial properties of the solution, preventing the growth of bacteria and fungi, which will damage the dried flowers and avoid corrosion and fading of the dried flowers. Then, specially treated dried flowers are placed in the liquid aromatherapy. When the dried flowers absorb the color-locking ingredients, the color becomes brighter and the appearance is richer, giving people a more vivid and easier to identify aromatherapy visually. Therefore, the dried flowers adjust the color projection by moisturizing, anti-oxidation, and film protection layer.

[0019] 2. Through the mass ratio of the color-locking composition disclosed in the present application, the color of the dried flowers is brighter and the shelf life is longer; if too little ethylene glycol stearate is added, the color of the dried flowers is not fresh enough and the color preservation time is shortened; if too little sodium carboxymethyl cellulose is added, the color is not realistic enough, the pigment is too concentrated, and the original color is lost. In addition, the dried flowers are more easily damaged, the ornamental value is poor, and the shelf life is shorter. DETAILED DESCRIPTION

The test results are shown in the table below. Chromatic Aberration Petals texture Mildew Material aroma Example 1 1.36 Moisturizing and soft No mildew normal Example 2 1.35 Moisturizing and soft No mildew normal Example 3 1.34 Moisturizing and soft No mildew normal Example 4 2.45 Softer No mildew normal Example 5 2.66 soft No mildew normal Example 6 1.35 Moisturizing and soft No mildew normal Example 7 2.68 soft No mildew normal Comparative Example 1 7.85 soft Mildew Lighter Comparative Example 2 7.91 simply Mildew Lighter Comparative Example 3 6.97 simply Mildew Heavy Comparative Example 4 4.34 soft Partial mildew Lighter Comparative Example 5 5.46 soft Partial mildew Lighter Comparative Example 6 5.29 simply Partial mildew Lighter

[0052] Combined with the table, Example 1 and Comparative Examples 1-6 are compared for color-locking aromatherapy of dried flowers. The results show that, no matter from the aspects of petal texture, color difference, anti-mildew ability and aromatherapy smell, Example 1 has better effect than the color-locking aromatherapy of dried flowers prepared in the comparative examples. The analysis shows that, through the lubricity and permeability of ethylene glycol stearate, it can penetrate into the dried flower molecules, so that the essence in the color-locking composition contacts the dried flowers, so that the dried flowers have antioxidant properties and rich aroma, and then sodium carboxymethyl cellulose forms a film protection on the surface of the dried flowers to prevent ultraviolet radiation, damage and discoloration, dipropylene glycol methyl ether has good solubility and surface tension, keeps the liquid aromatherapy ingredients stable, and then benzalkonium chloride is added to keep the solution antibacterial, prevent bacteria and fungi from growing, and then damage the dried flowers, avoid corrosion and fading of the dried flowers, benzalkonium chloride and the color-locking composition are mixed to enhance the anti-mildew properties of the dried flowers, and then the specially treated dried flowers are placed in the liquid aromatherapy. When the dried flowers absorb the color-locking components, the color becomes brighter, the appearance is richer, and visually gives people a more vivid and easier to identify aromatherapy feeling. Therefore, dried flowers have the function of locking color by adjusting the color projection through moisturizing, anti-oxidation, and film protection layer.

[0053] By comparing Example 1 with Examples 4-5, it can be seen that, no matter from the perspective of petal texture, color difference, mildew resistance, and aromatherapy smell, Example 1 has better effect on the color-locking aromatherapy of dried flowers than Examples 4-5. The analysis shows that, through the mass ratio of the color-locking composition disclosed in the present application, the color of the dried flowers is brighter and the shelf life is longer; too little ethylene glycol stearate is added, so that the color of the dried flowers is not fresh enough and the color preservation time is shortened; too little sodium carboxymethyl cellulose makes the color not realistic enough, the pigment is too concentrated, and the original color is lost, and the dried flowers are more easily damaged, the ornamental value is poor, and the shelf life is shorter.

[0054] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
