Description

Technical Field

[0001] The present invention relates to the technical field of heated tobacco products, and particularly to a sweet flavoring essence for heated tobacco products, tobacco sheet and heated tobacco products. Background Art

[0002] A heated tobacco product is a type of new tobacco product. The working temperature of its heating component is 250 - 350°C. Through a special heating source of the device, the tobacco in the "cartridge" is heated, so as to volatilize nicotine and flavor substances in the tobacco, generating smoke to meet the needs of smokers. In the state of non-combustion below 350°C, harmful substances produced by igniting and smoking traditional cigarettes are avoided.

[0003] However, the pyrolysis reaction of the tobacco in the heated tobacco product is relatively simple, and the release of aroma components is limited. Compared with traditional cigarettes, the heated tobacco product has insufficient aroma, lower smoke concentration, weak consumer satisfaction and uneven aroma during suction. Therefore, how to compensate the aroma of the heated tobacco product, increase the smoke concentration, enhance consumer satisfaction and achieve uniform release of aroma is one of the key technical problems urgently to be solved in this field.

[0004] Traditional sweet flavoring essences usually contain ketone and alcohol compounds, which can endow cigarettes with a natural sweet fragrance and play an important role in improving the quality of cigarettes. However, existing sweet flavoring essences have strong reactivity and volatility, and there is a problem of sweet taste attenuation when added to heated tobacco products. The carbonate derivatives of ketones and alcohols are chemically stable at room temperature and can undergo decomposition reactions when heated at 200 - 350°C, gradually releasing ketone and alcohol compounds, which have good application prospects as latent fragrance substances in flavoring heated tobacco products.

[0005] Therefore, providing a sweet flavoring essence suitable for heated tobacco products has become a technical problem urgently to be solved in this field. Summary of the Invention

[0006] The technical problem to be solved by the present invention is to provide a sweet flavoring essence for heated tobacco products, tobacco sheet and heated tobacco products, which overcomes the above defects of the prior art.

[0007] The technical problem to be solved by the present invention is realized through the following technical solutions:

[0008] A sweet flavoring essence for heated tobacco products, comprising a pyranone carbonate fragrance base and an auxiliary fragrance base. Among them, the pyranone carbonate fragrance base includes at least six kinds of pyranone carbonates and a solvent. The mass ratio of the sum of the masses of each pyranone carbonate to the mass of the solvent is (5 - 10):100, and the solvent is propylene glycol; the auxiliary fragrance base includes: Yunnan tobacco extract, jujube extract and tamarind extract; the mass ratio of the sum of the masses of the pyranone carbonates to the mass of the auxiliary fragrance base is 1:(1 - 3).

[0009] Preferably, the pyranone carbonate includes: pyranone leaf alcohol carbonate, pyranone citronellol carbonate, pyranone n-heptanol carbonate, pyranone cinnamyl alcohol carbonate, pyranone phenylpropyl alcohol carbonate, and pyranone tert-butanol carbonate.

[0010] Preferably, the mass ratio of pyranone leaf alcohol carbonate, pyranone citronellol carbonate, pyranone n-heptanol carbonate, pyranone cinnamyl alcohol carbonate, pyranone phenylpropyl alcohol carbonate, and pyranone tert-butanol carbonate is 1.0:(1.5 - 2.0):(0.5 - 2.0):(1.0 - 3.0):(0.5 - 1.0):(0.5 - 1.0).

[0011] Preferably, the mass ratio of tobacco extract, jujube extract, and tamarind extract in the auxiliary fragrance base is 1.0:(1.0 - 2.0):(1.0 - 3.0).

[0012] A tobacco sheet for a heated cigarette, wherein a sweet flavoring for a heated cigarette is added to the tobacco sheet for a heated cigarette, and the sweet flavoring accounts for 2 - 4% of the mass of the tobacco sheet.

[0013] A heated cigarette, comprising the above-mentioned tobacco sheet for a heated cigarette.

[0014] The above technical solution of the present invention has the following beneficial effects:

[0015] In this application, pyranone carbonate is used as the sweet flavor source of pyranone and alcohol compounds, effectively improving the disadvantages of strong volatility, easy deterioration, and high reaction activity of pyranone and alcohol compounds. Moreover, the pyranone carbonate flavor precursor substance in this application can release pyranone and various alcohol and other flavor substances by cracking at a temperature of about 300 °C, and the cracking transfer rate is as high as 80%. It can fully match the heating temperature of 280 - 330 °C of the heated cigarette and play their respective advantages and roles, and the sweet flavor can be evenly and stably released in the heated cigarette.

[0016] In addition, the special formula of the auxiliary fragrance base in this application can be coordinated with the sweet fragrance of the pyranone carbonate fragrance base, solve the problem of single aroma and taste, and can further improve and modify the aroma, improve the aroma quality, increase the sweet and moist feeling, increase the sensory comfort, reduce the irritation, and improve the smoking flavor and aftertaste.
