Description

Technical Field

[0001] This invention relates to a smokeless incense containing fragrant plants and its preparation method, belonging to the technical field of incense. Background Technology

[0002] China has a long history of handcrafting incense, with the most traditional method being the production of incense using agarwood as the raw material. However, the flavor and function of agarwood are limited and cannot meet the needs of consumers.

[0003] With the development of electronic information technology, staying at home is not only a preference of young people, but also affects middle-aged and elderly people. Spending long periods indoors can lead to stale air, and if cleaning is not done regularly, bacteria can easily grow, affecting health. Moreover, due to dietary and lifestyle habits, many people are in a sub-healthy state.

[0004] Ginger lily, also known as wild ginger lily, is a freshwater herbaceous plant belonging to the genus *Ginger lily* in the family Zingiberaceae. It grows to a height of 1-2 meters, with terminal, spike-like inflorescences. The calyx is tubular, and the leaves are alternate, long and narrow, pointed at both ends, glabrous on the upper surface and slightly hairy on the lower surface. It flowers from May to November, with each inflorescence typically bearing 10-15 flowers. Ginger lily is a common cut flower in southern my country during the summer, prized for its rich and fragrant aroma. It is widely cultivated in provinces such as Guangdong and Yunnan, where the cultivation techniques are easy to master and yields are high. This invention provides a smokeless incense containing fragrant plants, with ginger lily as the main ingredient. It not only has a pleasant aroma but also possesses antibacterial, insect-repellent, and disease-treating / preventing properties, and is long-lasting and durable. Summary of the Invention

[0005] This invention provides a smokeless incense containing fragrant plants and its preparation method, which enriches the variety of fragrances and health benefits of incense products.

[0061] Application examples

[0062] Using the extracts obtained in Examples 1-4, incense products were prepared according to the formulas in Table 5, respectively, and are designated as Incense Product 1# to Incense Product 4#. The specific preparation methods include:

[0063] 1) Mix the main material (the extract obtained in each example) with the auxiliary material evenly, let stand, and obtain a wet material with plasticity;

[0064] 2) Shape the obtained wet material and dry it in a cool, ventilated place for 2 days to obtain the finished fragrance product.

[0065] The incense sticks prepared in Examples 1-4 can be pinched firmly with the index finger and thumb without breaking, meeting the usage requirements.

[0066] Comparative Example 1

[0067] Comparative Example 1 used agarwood powder and water instead of fragrant plant extracts to prepare incense products according to the formula in Table 5, which are denoted as Incense Product 5#. The specific preparation method includes:

[0068] 1) Mix the main material and auxiliary material evenly, let stand, and obtain a wet material with plasticity;

[0069] 2) Shape the obtained wet material and dry it in a cool, ventilated place for 2 days to obtain the finished fragrance product.

[0070] Comparative Example 2

[0071] The difference from Example 1 is that the drying temperature is 110°C, while all other aspects are the same as in Example 1.

[0072] Comparative Example 3

[0073] The difference from Example 1 is that the extraction temperature was 15°C, while all other aspects were the same as in Example 1.

[0074] Comparative Example 4

[0075] The difference from Example 1 is that the extraction solvent was changed to toluene, while all other aspects were the same as in Example 1.

[0076] Comparative Example 5

[0077] The difference from Example 1 is that the extraction solvent was changed to chloroform, while the rest is the same as in Example 1.

[0078] Table 5 shows the formulas for each example.

[0079]

[0080] The above-mentioned manufacturer of Phoebe zhennan bark powder is: Mozhen; product name: Phoebe zhennan wood adhesive powder; fineness: 150 mesh or above.

[0081] Experiments have shown that incense products made primarily from Examples 1-4 can also be prepared in the form of incense coils, incense cones, etc.

[0082] Fragrance Product Evaluation and Testing

[0083] To evaluate the user experience of the incense products prepared in the above embodiments, user experience tests were conducted on the incense products prepared in each example. The specific test standards are as follows:

[0084] The total score for the odor evaluation is 5 points: 5 points is the standard for a harmonious and natural odor with a pleasant fragrance; 4 points is the standard for a harmonious odor with a certain fragrance; 3 points is the standard for a neutral odor with a certain unique odor, but overall harmonious and not unpleasant; 2 points is the standard for a certain amount of disharmonious odor with weak harmony, but can be generally adapted to after getting used to it; 1 point is the standard for a noticeable disharmonious odor that is unpleasant and cannot be adapted to.

[0085] Toughness evaluation: The incense stick is 22cm long and 3mm in diameter. One end is fixed and the other end is bent. If the bending angle is greater than 90°, it is considered Grade A; if the bending angle is greater than 60°, it is considered Grade B; if the bending angle is greater than 45°, it is considered Grade C; if the bending angle is greater than 30°, it is considered Grade D; and if the bending angle is greater than 15°, it is considered Grade E.

[0086] Table 6 Combustion performance evaluation results

[0087]

[0088] As shown in Table 6, the ginger flower extracts prepared in Examples 1-4 can effectively improve the aroma evaluation of incense products. The improvement effect varies depending on the variety of ginger flower used. The aroma of the incense products is pleasant, with scores of 4.7 or higher. The product obtained using white ginger flower from Example 1 has the best effect. The inventors found that the drying temperature should not be too high, otherwise the quality of the incense will decrease. The reason for this may be that high temperature will cause the loss of the effective components acting on the incense. Too low an extraction temperature will also reduce the extraction effect. At the same time, after repeated selection, the inventors found that the solvent with stronger solubility is not necessarily better. Stronger solubility may lead to the extraction of components that are not conducive to the quality of the incense, thus reducing the quality. Among them, anhydrous ethanol has the best effect.

[0089] Antibacterial test:

[0090] Suspensions of different bacterial strains were dripped onto white cloth and spread evenly. The cloth was then dried in a 37°C incubator to prepare a bacterial carrier (0.5 McFarland units). The bacterial carriers were then suspended in a 10-square-meter room, and incense products were lit. The sterilization effect was checked after 2 hours.

[0091] Table 7. Evaluation results of bacterial kill logarithmic values

[0092] Sample number Staphylococcus aureus Candida albicans mold E. coli Example 1 5.81 5.51 5.53 5.63 Example 2 5.76 5.46 5.51 5.59 Example 3 5.80 5.48 5.49 5.61 Example 4 5.69 5.43 5.50 5.58

[0093] The kill log values ​​of all embodiments were above 5, indicating that the sterilization effect was very good and it was beneficial to purify indoor air.

[0094] Mosquito repellent experiment:

[0095] The experiment was conducted in a shady park. Five participants had their arms, face, and neck exposed. No measures were taken for the first 30 minutes, and the average number of mosquito bites was 11 per person. Incense sticks prepared in Example 1 were lit. After one stick burned out, another one was lit in the same spot. The participants' activity range was within 6 meters of the incense sticks. After 2 hours, the average number of mosquito bites was 0 per person during the burning time of the incense sticks.

[0096] Sleep-inducing experiments:

[0097] Individuals with sleep disorders aged 20-50 years were recruited, with 50 participants per case. There were no statistically significant differences among the participants. Five months later, the Pittsburgh Sleep Quality Index (PSQI) was used for follow-up. The results were statistically analyzed. The intervention method in Example 1 was to light an incense stick before bedtime.

[0099] Sample number Before intervention After intervention Blank group 16.92±3.16 16.88±4.12 Example 1 16.83±4.36 4.88±1.81

[0100] It can be seen that the smokeless incense of this application has a calming and sleep-aiding effect, and has a significant therapeutic effect on sleep disorders.
