Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of new nicotine snus, and relates to a snus with expectorant effect and a preparation method thereof, in particular to a snus product with expectorant and nicotine intake functions and comfortable taste. BACKGROUND

[0002] Compared with the harm of traditional cigarettes and cigars, smokeless tobacco products are considered to be less harmful to human body. On the other hand, smokeless tobacco products are smoked through the mouth or nose, do not need to be burned, will not produce smoke, will not harm the lungs, and will also eliminate the production of "secondhand smoke", thereby reducing the harm of smoking to public health.

[0003] Smokeless tobacco products mainly include chewing tobacco, snus, nasal snuff, chewing gum tobacco and electronic cigarettes and other forms of products. There are two forms of snus sold on the market at present, one is bulk moist tobacco, and the consumer takes part of it by hand and puts it into the mouth each time; the other is a nicotine bag, which is placed between the lips and teeth when eaten. The snus on the market generally has a unique pungent and spicy, bitter and astringent taste, which is difficult for people to accept, and the user's taste experience is not good, which limits the promotion of the product in more market fields.

[0004] Traditional Chinese medicine is the treasure of the Chinese nation. There has been the theory of "medicinal food homology" in traditional Chinese medicine since ancient times. According to the functional compatibility of traditional Chinese medicine, natural ingredients extracted from medicinal food homology plants are added to snus, which not only has the traditional function of regulating taste, but also contains active ingredients that are beneficial to the health of smokers. Based on this, researchers in the domestic tobacco field try to develop more functional snus, which can provide consumers with a new oral experience and efficacy experience. SUMMARY

[0106] Test Example 1

[0107] Ten evaluators were organized to conduct sensory quality evaluations on the oral tobacco prepared in Examples 1-12 and Comparative Examples 1-6.

[0108] Table 1

[0109]

[0110] Table 2

[0111]

[0112]

[0113] As shown in Table 2, compared with the product of Comparative Example 6, the oral cigarette of the present invention, which contains plant extracts, has a superior taste and comfort, making the oral cigarette taste better and less irritating.

[0114] Comparing the products of Example 1 with those of Examples 5-7, it can be seen that the three components in the specific formula of the taste modifier used in this invention do not work independently, but rather work together to enhance each other and synergistically improve the comfort of the mouth-held tobacco taste.

[0115] Comparing the products of Example 1 with those of Examples 8-12, it can be seen that the choice of binder or pH adjuster in oral cigarettes also affects the taste quality to some extent.

[0116] Test Example 2

[0117] One hundred volunteers (with a smoking history of more than 10 years and symptoms such as throat sensitivity, discomfort, phlegm, and easy cough) were randomly divided into 10 groups based on their smoking history and the severity of their symptoms. Each group used the oral cigarettes prepared in Examples 1-4 and Comparative Examples 1-6 for 40 consecutive days. The frequency and amount of use were kept consistent across groups. The degree of improvement in symptoms such as throat sensitivity, discomfort, phlegm, and easy cough were then evaluated. The evaluation results included: very significant improvement, slight improvement, and almost no improvement. The number of people in each group was counted, and the evaluation results are shown in Table 3.

[0118] Table 3

[0119]

[0120]

[0121] As shown in Table 3, compared with the product of Comparative Example 6, the oral tobacco product of this invention, which contains plant extracts, has significantly better expectorant, antitussive, and throat-soothing effects.

[0122] As can be seen from the comparison of Example 1 and Comparative Examples 1-5, the five plant ingredients in the plant extract of the specific formula used in this invention do not work independently, but rather work together to enhance the expectorant, antitussive, and throat-soothing effects of oral smoking.

[0123] Comparing the products of Example 1 and Example 4, it can be seen that the extraction process of plant extracts also affects the expectorant, cough suppressant, and throat discomfort relief effects of oral cigarettes to some extent.
