Description

Technical Field

[0001] The invention belongs to the technical field of cigarette flavors, and particularly relates to a composition for increasing the herbal aroma characteristics of low-tar cigarettes, and a preparation method and application thereof. Background Art

[0002] As a natural product, tobacco is unique because it contains a variety of flavor molecules. To date, the most flavor molecules have been found in tobacco, more than twice as many as coffee, which ranks second. In addition, tobacco flavor is extremely complex and is affected by country, brand, and the company or organization it represents. There is currently no universally recognized tobacco flavor. "Chinese Cigarette Style Sensory Evaluation Method" uses graphics and quantitative data to intuitively describe the flavor and aroma type of cigarettes to meet the evaluation requirements of Chinese cigarette style characteristics. Among them, herbal aroma, as an important indicator of aroma style, plays an important role in the formation of cigarette style characteristics. Existing low-tar cigarettes often have common problems such as light smoke and insufficient aroma when reducing tar. Improving the herbal aroma characteristics of low-tar cigarettes is of great significance to the development of low-tar cigarettes.

[0003] CN115590238A discloses a cigarette additive with herbal aroma, and a preparation method and application thereof. The raw materials for preparing the cigarette additive with herbal aroma include Chinese herbal compound extract and flavoring liquid, and the raw materials for preparing the Chinese herbal compound extract include platycodon, mulberry leaf, epimedium and dogbun leaf. The cigarette additive with herbal aroma provided by the invention has the effects of clearing the orifices and relieving pain, relieving cough and expectoration, clearing the lungs and moistening dryness, clearing away heat and detoxifying, and can effectively relieve the symptoms of throat discomfort, dry lungs and excessive phlegm caused by smoking by consumers. The cigarette additive with herbal aroma provided by the invention is applied to cigarette formula tobacco, which can soften the smoke, harmonize the smoke fragrance, have significant style characteristics, and can clearly perceive the herbal aroma and flue-cured tobacco fragrance. At the same time, it has the effects of clearing the orifices, promoting body fluid and returning sweetness, relieving cough and moistening the lungs, which can not only meet the physiological needs of consumers for cigarette products, but also play a health care role for consumers.

[0004] CN108783572A discloses a highly loose tobacco sheet with herbal aroma and a production process for low-temperature cigarettes. The tobacco sheet is composed of the following raw materials in percentage by mass: 50-80% tobacco raw material powder, 10-30% atomizer, 0.5-10% adhesive, 0.01-0.2% leavening agent, 2-15% herbal plant powder, and 0-30% water. The tobacco sheet is manufactured by a roller pressing process. The production process is not changed during sheet manufacturing, and a leavening agent is added to the raw material formula to make the sheet loose, which is convenient for absorbing a large amount of atomizer and external fragrance. Herbal plant powder is used to replace external flavors, and consumers have a pleasant characteristic herbal aroma when they smoke, and the amount of smoke and physiological satisfaction obtained are stronger, which is closer to traditional cigarettes. At the same time, the sheet production process is mature and simple, with strong controllability and stable quality.

[0005] Although the above-mentioned cigarettes can also have herbal aroma characteristics through specific spices, the spices are mostly derived from natural plants, so the aroma quality is very unstable and difficult to control. Therefore, it is of great significance to develop a product that can give cigarettes a more stable herbal aroma. Summary of the invention
