Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of reconstituted tobacco leaf, and particularly relates to a reconstituted tobacco leaf for a heat-not-burn cigarette, a preparation method and application thereof. BACKGROUND

[0002] The heat-not-burn cigarette is an important form of new tobacco products, which mainly releases aerosol by heating and distillation (below 500 ℃) of tobacco materials. Because the tobacco materials contain a large amount of glycerol and other smoking agents, the smoking agents volatilize upon heating and remain in the oral cavity, which easily causes dryness in the oral cavity. The prior art can mask the dryness in the oral cavity by adding flavorings, such as menthol coolants, to produce a cooling sensation in the oral cavity. On the one hand, the retention of flavorings is poor, and they are easy to volatilize after a long period of storage; on the other hand, the consistency of flavorings before and after being released upon heating is poor during the heating and smoking process, and the dryness in the oral cavity is still obvious in the later stage of smoking.

[0003] There has been some research on the application of Chinese herbal medicine in reconstituted tobacco leaf. The existing method is to concentrate the Chinese herbal medicine extract and use it as a coating liquid to coat the reconstituted leaf, or to add Chinese herbal medicine extract residues to the raw materials of the reconstituted tobacco leaf for sheeting. However, regardless of the method used, the Chinese herbal medicine needs to be processed in series before use, and the medicinal effect is difficult to fully utilize.

[0004] CN1565283A discloses a production process of functional papermaking reconstituted tobacco leaf, including soaking, extraction, separation, pulping and coating processes. One or more functional components, such as Chinese herbal medicine and mint, are added during the soaking or soluble extract liquid preparation process, so that the papermaking reconstituted tobacco leaf has health care function or mint flavor, or both.

[0005] CN100569124C discloses a Chinese herbal medicine extract for papermaking reconstituted tobacco leaf, and a preparation and use method thereof. The extract is prepared from Platycladus orientalis, Ophiopogon japonicus, Radix Adenophorae, Momordica grosvenori, Lonicera japonica, Taraxacum mongolicum, Perilla frutescens and Glycyrrhiza uralensis by reflux extraction and concentration. The extract is added to the reconstituted tobacco leaf at a proportion of 1-5%, which can endow the cigarette product with unique aroma characteristics, enrich the aroma notes of the cigarette, and meet the characteristic needs of the cigarette product; and can also reduce the respiratory discomfort after smoking to some extent, and has good application prospect.

[0006] However, the above methods have not solved the problem of the difficulty in fully utilizing the medicinal effect of Chinese herbal medicine. Therefore, how to provide a method that can solve the dryness in the oral cavity during the smoking process of the heat-not-burn cigarette, and effectively combine the Chinese herbal medicine components with the reconstituted tobacco leaf, has become a problem to be solved. SUMMARY

[0007] In view of the deficiencies of the prior art, the purpose of the present application is to provide a heated cigarette reconstituted tobacco for improving oral comfort and a preparation method and application thereof. The heated cigarette reconstituted tobacco provided by the present application breaks through the single-layer structure and single function of traditional reconstituted tobacco, adds Chinese herbal medicine powder into the reconstituted tobacco, can effectively improve oral comfort, and can also endow the heated cigarette with medicinal effects such as heat-clearing and detoxifying, phlegm-eliminating and cough-relieving; the Chinese herbal medicine powder is subjected to salting-out action-expanding treatment, effectively improves the medicinal effect release performance, and can effectively adsorb glycerol in the outer reconstituted tobacco, reduces the water absorption of the reconstituted tobacco, and is beneficial to the storage and processing of the reconstituted tobacco.

[0008] To achieve the purpose of the present application, the following technical solutions are adopted in the present application:

[0069] Water content and glycerol content test:

[0070] The heating cigarette reconstituted tobacco leaf for improving oral comfort provided in Examples 1-9 and Comparative Examples 1-5 is equilibrated at 35% humidity for 4 days, and after the reconstituted tobacco leaf is dried, the outer two pieces of reconstituted tobacco leaf are separated with tweezers and the powdery material remaining on the reconstituted tobacco leaf is removed as much as possible. Then, the outer reconstituted tobacco leaf is equilibrated at 50% humidity for 2 days, and the water content and glycerol content of the outer reconstituted tobacco leaf are detected.

[0071] Detection of the amount of glycerol and menthol in the smoke:

[0072] The improved oral comfort heating cigarette reconstituted tobacco provided by Examples 1-9 and Comparative Examples 1-5 and the control sample were made into heating cigarettes, and a smoking test was conducted to detect the amount of glycerol released when heated (to measure the smoke release performance) and the amount of menthol (to evaluate the release effect of the drug effect), and the results are as follows:

[0073]

[0074] From the above data, it can be found that the preparation method provided by the present application can reduce the water absorption of the reconstituted tobacco, which is beneficial to the storage and processing of the reconstituted tobacco, and reduces the influence of the atomizing agent; by comparing Comparative Examples 1, 4-9 and Comparative Examples 1-2, it can be found that the present application can accelerate the generation of puffing gas, improve the puffing effect, and thus improve the product effect by selecting a specific inorganic salt in combination with a specific organic acid; by comparing Comparative Examples 1 and Comparative Examples 3-5, it can be found that the present application effectively improves the product effect by using a specific puffing treatment process.

[0075] The prepared heating cigarettes were then subjected to sensory quality evaluation, and the results are shown in the following table. In the table, the dry mouth feeling, the cool mouth feeling, and the sweet aftertaste feeling in the mouth are rated on a 5-point scale, with a higher score indicating a stronger sensory characteristic. 0-1 indicates weak, 2 indicates relatively weak, 3 indicates moderate, 4 indicates relatively strong, and 5 indicates strong.

[0076]

[0077] From the above data, it can be found that the reconstituted tobacco prepared by the present application for use in heating cigarettes can significantly improve the dry mouth feeling, enhance the cool mouth feeling and sweet aftertaste feeling, and improve the oral comfort.
