Description

An electronic cigarette liquid

technical field

The invention relates to an electronic cigarette liquid, which belongs to the technical field of electronic cigarettes.

Background technique

Traditional cigarettes generally provide consumers with nicotine and related tobacco aroma components by burning cigarettes. Due to pyrolysis and smoke migration during the smoking process, the mainstream smoke contains a large number of harmful components, and a small part of them, such as condensed aromatic hydrocarbons, have been proven to be carcinogenic. Cigarette smoking also produces a large amount of smoke, which not only causes environmental pollution, but also brings second-hand smoke hazards to non-smokers. With the gradual implementation of the International Tobacco Control Framework Convention and the gradual enhancement of people's health awareness, the traditional cigarette sales market has been greatly impacted. E-cigarettes use atomization to generate smog sensations, do not produce tar and CO, and produce almost no second-hand smoke hazards. They are regarded as pollution-free smoking cessation products or tobacco substitutes, and have received high attention and widespread attention from major tobacco companies at home and abroad. Research. At present, the sales market of e-cigarettes is mainly in the United States, while Europe and Asia have a good growth trend, especially the Chinese e-cigarette market is still in the stage of cultivation and development. The taste of the currently developed e-cigarette products tends to be mixed cigarettes, which are more in line with the taste habits of foreign consumers, while Chinese consumers prefer flue-cured tobacco, which has a stronger taste, and the taste of e-cigarettes is difficult to meet the requirements. Improving the formula of e-cigarette liquid to meet the habits of Chinese consumers is the key to opening up the Chinese market.

As a form of new tobacco products, electronic cigarettes present a huge market prospect. The main reason is that on the one hand, they provide consumption habits and satisfaction similar to traditional cigarettes, and on the other hand, the hazard index of electronic cigarettes is much lower than that of traditional cigarettes. The e-cigarette liquid formula is the key to highlight the advantages of e-cigarettes. In order to simulate the aroma, aroma and taste of traditional cigarettes to the greatest extent, the most common solution at present is to add tobacco extracts to the e-liquid. The tobacco essential oil obtained by extraction is mixed with an atomizer and a tobacco essence in a certain ratio to obtain an electronic cigarette liquid. The low hazard of e-cigarettes is that through the non-combustion method, what is inhaled into the human body is the atomized liquid rather than the combustion cracking product. Many Chinese herbal medicine plant components not only have certain characteristic aroma components, but also have certain health care effects, and even have the effect of alleviating certain diseases. The combination of tobacco extracts and Chinese herbal medicine extracts not only makes up for the shortcomings of the lack of aroma components in e-cigarette liquids to a certain extent, but also is different from foreign e-cigarette liquids, and can build Chinese-style e-cigarette liquids to meet consumer demand. People are used to it, and at the same time provide a certain health care effect.

The present invention prepares the Chinese herbal medicine extract with the effect of soothing the throat, and then mixes it with the tobacco extract and modifies it with suitable flavors and fragrances for tobacco, so as to prepare the extract with rich aroma, comfortable taste, good sense of satisfaction and An e-cigarette liquid that has the function of soothing the throat and moisturizing the throat.

Different degrees of impact on quality are assigned different points.

The irritation refers to the discomfort caused by inhaling the smoke produced by atomization of e-cigarette liquid on sensory organs, including the mouth, throat and nasal cavity.

The sense of satisfaction refers to the comprehensive experience on the sensory organs of the strength, concentration and fragrance of the smoke produced by the atomization of the e-cigarette liquid.

The concentration refers to the feeling of mouth fullness when the smoke generated by the atomization of the e-cigarette liquid is just sucked into the mouth.

The comfort level refers to the effect on the comfort level of the oral cavity after inhalation and exhalation of the smoke generated by the atomization of the e-cigarette liquid.

The characteristic style refers to: the main sensory difference performance of an e-cigarette liquid in terms of pleasure that is different from other similar e-cigarette liquids.

The tobacco fragrance refers to: the smell of the original fragrance of tobacco is felt by the senses during the smoking process.

The aroma quality refers to: the quality of the pleasant smell is felt through the sense of smell and taste during the evaluation process.

The amount of aroma refers to the amount of pleasant breath measured through the oral cavity and nasal cavity during the inhalation process.

The amount of smoke generated refers to the amount of smoke produced by the e-cigarette liquid through atomization.

The specific meaning of the score value of the e-cigarette liquid evaluation index is shown in the following table 1:

Table 1 Score value meaning table of sensory quality evaluation index of e-cigarette liquid

(3) Evaluation method: According to the evaluation indicators and scoring values in Table 1, the appraisers should evaluate the sensory quality of each evaluation index and record the evaluation results. The minimum scoring unit of the scoring value is 0.5.

(4) Statistics of the results: remove the lowest score and the highest score from the sensory quality evaluation results of all reviewers, and calculate the arithmetic mean of the remaining effective individual evaluation index scores, and keep the results to two decimal places. The comprehensive score of the sensory quality evaluation is the sum of the arithmetic mean of each individual index score to obtain the total score, and one decimal place is reserved for the result.

The e-cigarette liquid prepared in Examples 1-5 and the e-cigarette liquid prepared in Comparative Examples 1-3 were added to the electronic cigarette for sensory quality evaluation. The specific evaluation results are shown in Table 2. The scores of each evaluation index in Table 2 are the arithmetic mean scores of the effective scores of 9 reviewers.
