Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of reconstituted tobacco, and particularly relates to a heating cigarette reconstituted tobacco for improving throat comfort and a preparation method and application thereof. BACKGROUND

[0002] The heating cigarette is an important form of new tobacco products, and mainly releases aerosol through heating and distillation (below 500 DEG C) of tobacco materials. The current heating cigarette releases smoke through baking of the reconstituted tobacco, and the irritant substances in the smoke are easy to cause dryness and pungency in the throat.

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

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

[0005] CN100569124C discloses a Chinese herbal medicine extract for papermaking reconstituted tobacco 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 at a proportion of 1-5%, which can give the cigarette product a unique aroma characteristic, enrich the aroma of the cigarette, and meet the characteristic needs of the cigarette product. It can also reduce the respiratory discomfort after smoking to some extent, and has a good application prospect.

[0006] CN103141929 A discloses a preparation method of reconstituted tobacco for strengthening aroma characteristics. The residue of traditional Tibetan medicinal plant Baphalanodendron after conventional aroma component extraction is mixed with tobacco stems and tobacco shreds in a certain proportion, and then soaked and extracted with hot water. The obtained insoluble substance is made into a base sheet by papermaking method. The obtained water extract is vacuum concentrated and used for coating on the base sheet to prepare the reconstituted tobacco. When applied to the cigarette formula, it has the effects of enhancing woody aroma, incense, sweet aroma and strengthening aroma characteristics, and reducing irritation and increasing moistening feeling.

[0007] However, the above methods cannot solve the problem that the efficacy of Chinese herbal medicine cannot be fully utilized. Therefore, how to provide a method capable of solving the discomfort of the throat during the smoking process of a heated cigarette and effectively combining Chinese herbal medicine components with reconstituted tobacco leaves has become a problem to be solved. SUMMARY

[0008] In view of the deficiencies of the prior art, the purpose of the present application is to provide a reconstituted tobacco leaf for a heated cigarette for improving throat comfort and a preparation method and application thereof. The reconstituted tobacco leaf for a heated cigarette provided by the present application breaks through the single-layer structure and single function of traditional reconstituted tobacco leaves, adds Chinese herbal medicine to the reconstituted tobacco leaves, which can effectively improve throat comfort and has a therapeutic effect on symptoms of pharyngolaryngeal inflammation such as dry cough and swollen pain. The Chinese herbal medicine powder is subjected to salting-out action-expansion treatment, which effectively improves the efficacy release performance, can effectively adsorb glycerol in the outer reconstituted tobacco leaves, reduces the water absorption of the reconstituted tobacco leaves, and is beneficial to the storage and processing of the reconstituted tobacco leaves.

[0009] To achieve the purpose of the present application, the following technical solutions are adopted:

[0010] In a first aspect, the present application provides a preparation method of a reconstituted tobacco leaf for a heated cigarette for improving throat comfort, which comprises the following steps:

[0024] Preferably, the mass of the bulking agent is 1-5% of the mass of the Chinese herbal medicine, for example, 1%, 2%, 3%, 4% or 5%, but is not limited to the above-mentioned values, and other values not listed in the above-mentioned value range are also applicable.

[0025] Preferably, the mass of the salt is 1-20% of the mass of the Chinese herbal medicine, for example, 1%, 5%, 10%, 15% or 20%, but is not limited to the above-mentioned values, and other values not listed in the above-mentioned value range are also applicable.

[0069] Effect test:

[0070] The following test takes the double-layer reconstituted tobacco without the sandwiching treatment as a control sample.

[0071] Moisture content detection:

[0072] The heat-not-burn reconstituted tobacco leaf provided by examples 1-9 and comparative examples 1-5 to improve throat comfort was balanced at 35% humidity for 4 days to dry the reconstituted tobacco leaf, and then the outer two pieces of reconstituted tobacco leaf were separated by tweezers and the powdery substance remaining on the reconstituted tobacco leaf was removed as much as possible. Then the outer reconstituted tobacco leaf was balanced at 50% humidity for 2 days to detect the water content and glycerol content of the outer reconstituted tobacco leaf. The reconstituted tobacco leaf without sandwiching treatment was balanced at 50% humidity for 2 days to detect the water content.

[0073] Detection of glycerol and menthol in smoke:

[0074] The heat-not-burn reconstituted tobacco leaf provided by examples 1-9 and comparative examples 1-5 to improve throat comfort and the control sample were made into heat-not-burn cigarettes and subjected to smoking test to detect the glycerol content (used to measure the smoke release performance) and menthol content (used to evaluate the release effect of medicinal efficacy) released during heating, and the results were as follows:

[0075]

[0076] 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 leaf, facilitate the storage and processing of the reconstituted tobacco leaf, and reduce 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 example 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.

[0077] Then the prepared heat-not-burn cigarettes were subjected to sensory quality evaluation, and the results were as follows. In the table, throat irritation, throat cooling sensation, and throat sweetness return were evaluated on a 5-point scale, with higher scores indicating stronger sensory characteristics. 0-1 indicates weak, 2 indicates relatively weak, 3 indicates moderate, 4 indicates relatively strong, and 5 indicates strong.

[0078]

[0079] From the above data, it can be found that the reconstituted tobacco leaf prepared by the present application for heat-not-burn cigarettes can significantly reduce throat irritation, improve throat cooling sensation and sweetness return, and improve throat comfort.

[0080] The applicant declares that the heat-not-burn reconstituted tobacco leaf of the present application to improve throat comfort and the preparation method and application thereof are illustrated by the above examples, but the present application is not limited to the above examples, i.e. it does not mean that the present application must rely on the above examples to be implemented. It should be understood by those skilled in the art that any improvement on the present application, equivalent replacement of each raw material of the product of the present application, addition of auxiliary ingredients, selection of specific methods, etc. all fall within the protection scope and disclosure scope of the present application.
