Description

Technical Field

[0001] This patent belongs to the technical field of heat-not-burn smoking devices, and specifically relates to an aerosol-generating article with an icy clove essence and a preparation method thereof. Background Art

[0002] Heat-not-burn cigarettes are also known as heated cigarettes, low-temperature cigarettes, and HNB. Heat-not-burn cigarettes are a new type of cigarette product that uses heating instead of combustion to release nicotine and other chemical substances, thereby reducing harmful substances generated by tobacco combustion. Heat-not-burn cigarettes can be divided into five technologies according to different heating principles: resistance heating, electromagnetic heating, infrared heating, fuel heating, and physicochemical reaction heating. IQOS has two new electromagnetic heating heat-not-burn devices, namely "IQOS ILUMA" and "IQOS ILUMA PRIME", and 11 flavors of special tobacco cartridges "TEREA". Through market research, since the launch of electromagnetic heating products, they have expanded rapidly.

[0003] Electromagnetic heating heat-not-burn cigarettes (EHNB) are one of the core technical branches of new tobacco products. Through the principle of electromagnetic induction, the temperature of the tobacco matrix (such as a tobacco cartridge) is accurately controlled for heating to release nicotine and flavor substances, avoiding tar and a large number of harmful components generated by traditional combustion. Its technology combines materials science, electromagnetic engineering, and atomization dynamics, becoming the core direction of the global tobacco industry transformation. The disadvantage of electromagnetic heating is that the built-in metal induction sheet or heating barrel of electromagnetic heating cigarettes is also prone to problems such as uneven heating, resulting in uneven aroma release, insufficient aroma quantity, generation of off-flavors, increased irritation, etc., and the experience is degraded.

[0004] As a composite functional essence, the icy clove essence has seen a rapid increase in application research in the field of heat-not-burn cigarettes in recent years. Its core value lies in balancing the need for harm reduction and sensory experience. Through the synergistic effect of the "cool feeling" and the "spicy fragrance note", it solves problems such as the thin taste and aftertaste residue of low-temperature heated tobacco. After the iterative upgrade of heat-not-burn cigarette heating appliances in recent years, each cigarette factory has relatively mature technology in needle-type inner core heating, and then developed electromagnetic heating appliances with independent intellectual property rights. The existing icy clove essence for heat-not-burn cigarettes used for needle-type inner core heating still has certain problems after being tested on heat-not-burn cigarette (electromagnetic heating) appliances, mainly reflected in the change of heating method, the change of temperature rise curve, insufficient aroma quantity during the suction process of icy clove cigarettes, generation of off-flavors, increased irritation, etc. Summary of the Invention

[0084] Unless otherwise specified below, the aerosol-forming matrix used is the C3F Qinyan 96 flue-cured tobacco leaves from Mianchi, Sanmenxia, Henan in 2021.

[0085] The inventors also conducted experiments using the following flue-cured tobacco leaves: Chenzhou Guiyang B2F, C2F, X2F; Yongzhou Lanshan B3F, C2F, X2F; Sanmenxia Mianchi B2F, C3F, X3F; Guizhou Zunyi B2F, C2F, X2F; Bijie Dafang B3F, C3F, X2F; Guizhou Bijie B2F, C2F, X3F; Yunnan Yuxi B3F, C3F, X2F; Yunnan Kunming B2F, C3F, X2F; Yunnan Dali B2F, C3F, X2F, including tobacco seed varieties such as Honghuadajinyuan, Cuibi No. 1, and Qinyan 96. In addition, the inventors also conducted experiments using burley tobacco, oriental tobacco, cigar tobacco, sun-cured yellow tobacco, and cloves. Unless otherwise specifically stated below, it is represented that this patent is equally applicable to the above raw materials.

[0086] To facilitate the description of the working mode of the aerosol-generating article of this patent, as Figure 3 shown, the aerosol-generating article generally adopts the form of a heated cigarette rod, specifically an electromagnetic heating non-combustible cigarette, including an aerosol-forming matrix section 13, a cooling section 12, and a filter section 11 from the distal end to the proximal end of the mouthpiece. The cooling section 12 and the filter section 11 can be combined into a filter rod assembly. In another specific embodiment, the filter rod assembly can include other forms of cooling structures, filtering structures, and air intake structures. There is a sensor in the aerosol-forming matrix section 13. The electromagnetic induction heating appliance 2 is arranged to receive the aerosol-forming matrix section 13 so that the aerosol-forming matrix in the aerosol-generating article generates aerosol. The electromagnetic induction heating appliance 2 and the aerosol-generating article inserted therein constitute an aerosol-generating system. Among them, the aerosol-generating article can be the aerosol-generating article in any of the following schemes. The electromagnetic induction heating appliance 2 includes a housing, a power supply, and a control component 22, a heating chamber 21 for receiving at least a part of the aerosol-generating article, and an electromagnetic wave emission induction coil 23 as an induction source. When the aerosol-generating article is inserted into the electromagnetic induction heating appliance 2, the power supply and the control component 22 start the heating mode. The electrical energy of the power supply is provided to the induction coil 23 in an alternating current manner and provided to the sensor in the form of electromagnetic waves. After receiving the energy, the sensor can heat the aerosol-forming matrix section.

[0087] Although coumarin has a long history of application in aerosol-generating products, adding coumarin to aerosol-generating products can improve the sensory quality of aerosol-generating products. However, due to its potential health risks, its use in tobacco products has been prohibited or restricted in many countries and regions. For example, in July 2010, Taiwan, China, issued a notice banning the addition of coumarin to food and strictly restricting the residual amount of coumarin in beverages caused by the use of natural flavors. Moreover, the application of raw materials without coumarin in aerosol-generating products has further highlighted problems such as insufficient aroma amount, generation of off-flavors, and increased irritation. Therefore, this patent provides an aerosol-generating product with an ice-cooled clove essence suitable for electromagnetic induction heating appliances, formulating an ice-cooled clove essence for electromagnetic induction heated non-combustible cigarettes by mixing specific spices in an appropriate proportion. This essence can effectively enhance the clove fragrance, improve the aroma texture, mask off-flavors, reduce irritation, improve the taste, and enhance the sensory experience of consumers.

[0088] Clove is a natural plant rich in nutrients. The main components of cloves include eugenol, syringaldehyde, syringic acid, linalool, etc. Among them, eugenol is the main aroma component of cloves and has various effects such as antioxidant, antibacterial, and antiviral. Syringaldehyde is the main active ingredient of cloves and has effects such as analgesic, antibacterial, and anti-inflammatory. Syringic acid and linalool also have antibacterial, antioxidant, and antiviral effects. Cloves have a unique aroma and taste, can improve the taste and flavor of aerosol-generating products, and enhance the quality and taste experience of aerosol-generating products. In addition, cloves also have analgesic and anti-inflammatory effects. Cloves mainly consist of flower buds and flower stalks. The main components of clove flower buds are eugenol and syringaldehyde, and clove flower bud oil is formed by extraction using the supercritical carbon dioxide extraction method. Eugenol is a strong aromatic substance and has many benefits for the human body, such as antioxidant, antibacterial, and antiviral. Syringaldehyde is a strong flavor substance and has effects such as analgesic, antibacterial, and anti-inflammatory. In addition, clove flower buds also contain rich components such as volatile oils and aromatic acids, and these components all have various effects such as antioxidant and antibacterial.

Preferably, the propylene glycol accounts for 20%-30% of the total amount of the essence. Adding more will have a negative impact on sheet adhesion.

[0094] In order to ensure that the Sri Lankan cinnamon bark oil does not contain coumarin, the following distillation optimization method is adopted:

[0095] Place the Sri Lankan cinnamon bark oil in a distillation kettle, and slowly heat it to boiling; control the distillation temperature at 120-140°C under normal pressure, and the distillation time is 30-60 minutes. Collect the part of the distillate that does not contain coumarin; use an efficient condensation system, preferably an efficient serpentine condenser, and control the condensation water temperature at 20-30°C to separate high-purity coumarin-free cinnamon bark oil (that is, Sri Lankan cinnamon bark oil with coumarin removed).

[0096] Use a gas chromatography-mass spectrometry (GC-MS) to quantitatively analyze the coumarin in the separated high-purity coumarin-free cinnamon bark oil to ensure that its content is lower than the detection limit (<0.01mg / g). The detection results are as Figure 1 shown, which is equivalent to the detection chart of the coumarin-free cinnamon bark oil standard sample of Figure 2 . 8.217min is the HZS peak, and 12.030min is the XDS peak. After detection, XDS (coumarin) and HZS (safrole) are not detected in the detected sample.
