Description

Technical Field

[0001] This invention belongs to the field of oral products, specifically relating to an oral product, its preparation method, and its application. Background Technology

[0002] Mouthwash is made by mixing cellulose and other materials as the main filler with nicotine, flavorings, sodium carbonate, and water. Compared to smoking, mouthwash does not produce harmful substances such as tar. However, recent studies have shown that due to its high alkalinity and the presence of irritating components such as nicotine, long-term use of mouthwash can cause irreversible damage to the oral cavity. These drawbacks severely limit the large-scale promotion and use of mouthwash.

[0003] Traditional Chinese medicinal herbs are largely rejected by consumers due to their unpleasant odor and extremely bitter taste, especially in mouthwash products, which require prolonged use. Adding medicinal herbs, even in trace amounts, to mouthwash would result in a strong herbal odor and a bitter, astringent taste, making it unacceptable to consumers. Furthermore, with rising living standards, people increasingly seek the natural and pleasant aromas of fragrances and flavorings. However, traditional natural fragrances are extremely difficult to preserve, especially when mixed with cellulose or plant powders, causing rapid evaporation. Additionally, mixing natural essential oils and plant powders can lead to yellowing and discoloration, severely impacting the customer experience. Therefore, currently, industrially produced mouthwash products do not incorporate Chinese medicinal herbs or natural fragrances and flavorings. Summary of the Invention

[0004] In order to overcome the problems existing in the prior art, one of the objectives of the present invention is to provide a mouth-holding product.

[0005] The second objective of this invention is to provide a method for preparing an oral product.

[0006] A third objective of this invention is to provide the application of the above-mentioned oral products in the field of tobacco products.

[0007] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0008] The first aspect of the present invention provides an oral product comprising the following components in weight percentages: 0.1-20% curing agent, 5-80% filler, 0.2-60% traditional Chinese medicine powder, and 0.5-20% plant essential oil; wherein the curing agent contains at least one functional group selected from carboxyl, ester, and hydroxyl groups.

[0009] Preferably, the plant essential oil is dispersed in the curing agent.

[0010] Preferably, the curing agent is selected from at least one of lauric acid, palmitic acid, myristic acid, stearic acid, hawthorn acid, arachidic acid, monoglyceride, and diglyceride. The curing agent in this invention encapsulates the plant essential oils and traditional Chinese medicine powder components through physical coating, preventing the plant essential oils from yellowing or volatilizing upon contact with air. It also prevents the traditional Chinese medicine powder from directly contacting the mouth, reducing the odor and astringency of the medicine. Furthermore, the curing agent and filler in this invention jointly encapsulate the plant essential oils and traditional Chinese medicine powder, giving the resulting oral product advantages such as long-lasting aroma and good invigorating effect.

[0011] Preferably, the filler is selected from at least one of microcrystalline cellulose, sodium alginate, hydroxypropyl cellulose, carrageenan, chitosan, ethyl cellulose, carboxymethyl cellulose, cyclodextrin, xylitol, and mannitol.

[0012] Preferably, the plant essential oil is selected from at least one of peppermint oil, lemon oil, wintergreen oil, sweet orange oil, patchouli oil, grapefruit oil, jasmine essential oil, citrus essential oil, peach essential oil, strawberry essential oil, lavender essential oil, banana essential oil, kiwi essential oil, apple essential oil, and rose essential oil.

[0013] Preferably, the curing agent has a mass percentage of 0.1% to 5%.

[0014] Preferably, the mass percentage of the herbal powder is 0.2%-50%. This invention primarily favors invigorating herbal powders, such as mugwort powder, to give the oral product an invigorating effect.

[0015] Preferably, the herbal powder includes at least one of the following: mugwort powder, peppermint powder, patchouli powder, and holly powder.

[0016] Preferably, the mugwort powder is obtained by crushing the whole mugwort plant or a portion of it.

[0017] Preferably, the oral product is selected from oral cigarettes, oral tablets, or chewing gum.

[0018] A second aspect of the present invention provides a method for preparing the oral product described in the first aspect of the present invention, comprising the following steps:

[0019] S1: The curing agent is heated and then mixed with plant essential oils to obtain a mixture;

[0020] S2: Mix the mixture with filler and traditional Chinese medicine powder to obtain the oral product.

[0021] Step S1 of this invention yields a mixture after solidification treatment of plant essential oils. This step can achieve the encapsulation of plant essential oils, preventing them from evaporating or turning yellow.

[0022] Preferably, step S1 is: heating and melting the curing agent, then mixing it with plant essential oil, stopping the heating, and obtaining the mixture.

[0023] Preferably, step S2 is: mixing the mixture sequentially with a filler and a traditional Chinese medicine powder to obtain the oral product.

[0024] Preferably, the heating temperature is 60–100°C. The curing agent melts upon heating, then mixes with the plant essential oil and coats the surface of the essential oil, isolating it from air and preventing oxidation, yellowing, or volatilization.

[0025] A third aspect of the invention provides the application of the oral product described in the first aspect of the invention in the field of tobacco products.

[0026] The beneficial effects of this invention are as follows: The oral product of this invention uses traditional Chinese medicine powder, such as mugwort powder, as the main ingredient for refreshing and invigorating the mind. Furthermore, the plant essential oil is solidified and encapsulated using a curing agent, and then mixed with fillers and the Chinese medicine powder to prepare a natural, green, healthy, and pleasantly fragrant oral product for refreshing and invigorating the mind. This oral product not only solves the problem of unacceptable odors from traditional Chinese medicine, but the solidification treatment of the plant essential oil also solves the problems of easy volatility, yellowing, and discoloration of natural plant essential oils. The resulting oral product retains a rich aroma and a long-lasting refreshing and invigorating effect even after long-term storage. Attached Figure Description

[0119]

[0120] Performance testing

[0121] (1) Sensory test results

[0122] This experiment selected 20 professional sensory evaluators (10 men and 10 women) to evaluate the Chinese herbal oral smoke products in Examples 1-3 and Comparative Examples 1-3. The bitterness, herbal taste, fruity aroma, stimulating effect, and color change of the Chinese herbal oral smoke products were tested. The specific test results are shown in Table 2 below.

[0123] Then, observe whether the oral smoke from the traditional Chinese medicine in Examples 1-3 and Comparative Examples 1-3 undergoes color change after being placed at room temperature for 120 days, and record the test results in Table 2 below. The actual image of the oral smoke from Example 1 after storage is shown below. Figure 1 As shown in (a), a photograph of the Chinese herbal medicine in Comparative Example 1 after oral storage with smoke is shown. Figure 1 As shown in (b).

[0124] Table 2. Sensory test results of oral inhalation of traditional Chinese medicine in Examples 1-3 and Comparative Examples 1-3.

[0125]

[0126]

[0127] Depend on Figure 1 As shown in Table 2, Example 1 uses a curing agent to solidify the natural peppermint oil, which prevents the natural peppermint oil from evaporating or turning yellow, resulting in a good aroma and a significant refreshing effect. In contrast, Comparative Example 1, which uses peppermint oil directly added to a smoking product, showed that after 120 days of storage, the components evaporated onto the outer white non-woven fabric packaging bag, causing significant discoloration and yellowing, and the bag lost its aroma. This indicates that without solidification and encapsulation, the natural plant essential oils will rapidly evaporate and turn yellow.

[0128] (2) Aroma retention test

[0129] Both Example 1 and Comparative Example 1 used natural peppermint oil. The main aroma component of natural peppermint oil is menthyl acetate. By directional tracking of menthyl acetate, the aroma retention in the oral cigarettes prepared in Example 1 and Comparative Example 1 can be quantitatively calculated. The specific test method is as follows: the oral cigarette products are placed in room temperature air, and samples are taken at 14, 30, 60, 90, and 120 days to test the content of menthyl acetate in the oral cigarettes. Based on the test results, a curve is plotted to obtain the rate of change of menthyl acetate over time. (See details below.) Figure 2 As shown. By Figure 2 It can be seen that the oral cigarette prepared by encapsulating peppermint oil with a curing agent in Example 1 had a residual ethanol-menthol ester content of 81% after 120 days of storage, with minimal attenuation and good aroma persistence. In contrast, Comparative Example 1, which directly added peppermint oil to the oral cigarette, had a residual ethanol-menthol ester content of only 29% after 120 days of storage, with a significant attenuation and poor aroma persistence. The oral cigarette would have no aroma or a very weak aroma when used.

[0130] In summary, the oral cigarette provided by this invention uses mugwort leaves, a traditional Chinese medicinal herb, as the main ingredient for refreshing the mind. By solidifying natural plant essential oils and mixing them with Chinese medicinal powder, a natural, green, healthy, and pleasantly fragrant oral cigarette for refreshing the mind is prepared. This not only solves the problem of unacceptable smells of traditional Chinese medicinal herbs, but also solves the problems of easy volatility, yellowing, and discoloration of natural fragrances through the solidification process of plant essential oils, greatly enhancing the product experience and providing a solution for the utilization of traditional Chinese medicinal herbs.

[0131] The embodiments of the present invention have been described in detail above. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention. Furthermore, the embodiments of the present invention and the features thereof can be combined with each other unless otherwise specified.
