Description

Technical Field

[0001] This invention belongs to the field of heated cigarette technology, specifically relating to a heated cigarette based on modified starch hydration for smoking and its usage method. Background Technology

[0002] With increasing health awareness and the implementation of smoking bans in public places, consumer demand for low-harm cigarettes is rising. Traditional cigarettes produce a large amount of harmful substances when burned, such as tar, carbon monoxide, and nicotine, posing serious health risks. Heated cigarettes, on the other hand, use low-temperature heating technology, typically below 350℃. At this temperature, nicotine and other flavor components in the tobacco volatilize to produce aerosols, reducing harmful components and thus gaining popularity among consumers.

[0003] CN113647666A discloses a method for preparing heated cigarettes. Addressing the problem that adding tobacco to heated cigarettes can easily cause adverse effects such as dryness and irritation in the throat, this method innovatively uses hydrated organic acid salts as humectants and 1,2-propanediol and glycerin as smoking agents to prepare tobacco specifically for heated cigarettes. Within the commonly used heating temperature range of below 400℃ for heated cigarettes, moisture is released at specific temperatures depending on the heating device, thus achieving the purpose of controlling the amount of moisture released.

[0004] CN111728267A discloses a heated cigarette, its plant-based fastener, and a manufacturing method thereof. The plant-based fastener has a first end and a second end, and the plant-based fastener forms at least one diffusion channel from the first end to the second end. The plant-based fastener is molded from a paste-like mixture formed by 3-5 parts by weight of plant raw material powder, 4-6 parts by weight of binder, 4-6 parts by weight of smoke-generating agent, and 4-6 parts by weight of water.

[0005] In existing technologies, heated cigarettes mostly rely on high-temperature atomization using smoke-generating agents such as propylene glycol / glycerin. Long-term inhalation may induce respiratory irritation, and the smoke released by tobacco also contains pyrolysis byproducts such as nitrosamines. From a consumer health perspective, how to meet consumers' physiological needs while also satisfying their demand for safety and non-irritation is a problem that tobacco scientists should consider. Summary of the Invention

[0006] To address the shortcomings of existing technologies, this invention provides a heated cigarette based on modified starch hydration and its application method.

[0007] To achieve this objective, the present invention adopts the following technical solution:

[0008] In a first aspect, the present invention provides a heated cigarette based on modified starch hydration for smoking, wherein the heated cigarette comprises a filter rod section, a core section and an aerosol generating section connected in sequence from the near end to the far end;

[0009] The filter rod section, the cigarette core section, and the aerosol generation section are formed by wrapping cigarette tipping paper.

[0010] The aerosol generating section is filled with modified starch and hydrated burst beads.

[0011] This invention utilizes the physical process of modified starch hydration and swelling to generate smoke, avoiding chemical atomization and high-temperature pyrolysis. All components of the smoke-generating agent used comply with FDA 21 CFR 184 food additive standards. The smoke component is edible starch gel that naturally degrades within 48 hours, posing no toxic risk upon inhalation. The modified starch has a better capacity to carry flavor molecules (such as nicotine) than glycerin, extending the aroma duration by 40%, thus enhancing the sensory experience for consumers. Furthermore, the heated cigarette does not require a heating device and operates at a low temperature throughout the process, avoiding harmful substances (benzo[a]pyrene, nitrosamines, etc.) produced by pyrolysis, thereby further mitigating the harmful effects of smoking.

[0012] Preferably, the modified starch includes esterified starch.

[0013] Preferably, the esterified starch comprises octenyl succinate starch.

[0014] In this invention, the modified starch is selected as octenyl succinate starch, which can quickly gelatinize and swell when it comes into contact with water, and the swelling volume is larger, releasing starch gel particles to form more smoke, thereby better carrying the flavor molecules in cigarettes.

[0015] Preferably, the modified starch has a particle size of 5-50 μm, for example, it can be 10 μm, 15 μm, 20 μm, 25 μm, 30 μm, 35 μm, 40 μm or 45 μm.

[0016] Preferably, the wall material of the hydrated burst beads is gelatin or hydroxypropyl methylcellulose, and the inner core is distilled water.

[0017] Preferably, the diameter of the hydrated burst beads is 2-5mm, for example, it can be 2.5mm, 3mm, 3.5mm, 4mm or 4.5mm.

[0018] Preferably, the filler of the aerosol generating section further includes a smoke-enhancing agent.

[0019] Preferably, the amount of the smoke-generating enhancer added is 0.5-2% of the total mass of the modified starch, for example, it can be 0.6%, 0.8%, 1%, 1.2%, 1.5%, 1.7% or 1.9%, etc.

[0020] As a preferred technical solution of the present invention, by adding a smoke-enhancing agent in the aerosol generation section, the smoke density and stability can be better improved, thereby improving the taste and satisfaction of heated cigarettes.

[0021] Preferably, the smoke-enhancing agent includes any one or a combination of at least two of lecithin, monoacetylglycerol, glycerol, diacetylglycerol, or triacetylglycerol;

[0022] Preferably, the smoke-enhancing agent is lecithin.

[0023] Preferably, the filling material of the core segment includes any one or a combination of at least two of the following: shredded tobacco, tobacco sheets, tobacco extract, nicotine, or nicotine derivatives.

[0024] Preferably, the filter rod segment is made of cellulose acetate tow and / or polylactic acid tow.

[0025] Preferably, the tipping paper has a basis weight of 35-50 g / cm³. 2 For example, the paper material can be 36 g / cm³. 2 38 g / cm 2 40 g / cm 2 42 g / cm 2 45g / cm 2 48 g / cm 2 50 g / cm 2 52 g / cm 2 Or 54 g / cm 2 .

[0026] Preferably, the end of the aerosol generating section that is not connected to the core section is also connected to a plug;

[0027] Preferably, the connection between the aerosol generating section and the plug is wrapped with splicing paper.

[0028] Secondly, the present invention provides a method of using a heated cigarette based on modified starch hydration as described in the first aspect. The method includes: breaking the hydration capsule during inhalation to release the distilled water in the core; the modified starch gelatinizes and expands upon contact with water; and the airflow generated by the expansion flows out sequentially from the core section and the filter rod section into the mouth.

[0029] All the specific point values ​​within the above range can be selected, and will not be elaborated on here.

[0030] Compared with the prior art, the present invention has the following beneficial effects:

[0031] This invention utilizes the physical process of modified starch hydration and swelling to generate smoke, avoiding chemical atomization and high-temperature pyrolysis. All components of the smoke-generating agent used comply with FDA 21 CFR 184 food additive standards. The smoke component is edible starch gel that naturally degrades within 48 hours, posing no toxic risk upon inhalation. The modified starch has a better capacity to carry flavor molecules (such as nicotine) than glycerin, extending the aroma duration by 40%, thus enhancing the sensory experience for consumers. Furthermore, the heated cigarette does not require a heating device and operates at a low temperature throughout the process, avoiding harmful substances (benzo[a]pyrene, nitrosamines, etc.) produced by pyrolysis, thereby further mitigating the harmful effects of smoking.

[0061] Comparative Example 1

[0062] This comparative example provides a heated cigarette, the structure of which includes a filter rod section, an empty paper tube and a cigarette core section connected in sequence from the near end to the far end.

[0063] Test Example 1

[0064] The heated cigarettes of Examples 1-8 and Comparative Example 1 were smoked on a smoking machine. (When smoking the heated cigarettes of Examples 1-8, the hydration capsule was broken to release the distilled water in the core. The modified starch gelatinized and expanded upon contact with water, and the airflow generated by the expansion flowed out from the core section and the filter rod section and into the mouth in sequence.) The temperature of the smoke at the outlet was measured using the thermocouple temperature measurement method according to the Canadian deep smoking mode (smoking time set to 3 seconds). The thermocouple was fixed 1 mm from the center of the outlet of the heated cigarette filter section. The thermocouple was connected to a temperature data acquisition system to measure the temperature of the smoke at the outlet of the heated cigarette mouthpiece during smoking.

[0065] The results are shown in Table 1.

[0066] Table 1

[0067]

[0068] Test Example 2: Consumer Sensory Testing

[0069] Sixty-three consumers who frequently use heated cigarettes were randomly selected and divided into nine groups of seven. Each group smoked heated cigarettes from Examples 1-8 and Comparative Example 1. Consumers were then asked to rate their experience with the temperature, taste, and satisfaction using a 5-point scale: 4.5 or higher indicated excellent (very satisfied); 4-4.5 indicated good; 3-4 indicated acceptable; and below 3 indicated poor. The scores for each group were the average of the five participants. The results are shown in Table 2.

[0070] Table 2

[0071]

[0072] As shown in Tables 1-2, compared with the heated cigarettes of Comparative Example 1, the heated cigarettes of Examples 1-3 of the present invention have a lower inlet temperature, resulting in a better user experience.

[0073] As can be seen from Example 4, when there is no plug, the airflow brought by the expansion of modified starch can flow out directly, which in turn affects the airflow at the inlet and results in poor satisfaction.

[0074] As can be seen from Example 5, when the modified starch is not the esterified starch defined in this invention, its volume after expansion is small, which will affect consumer satisfaction.

[0075] As can be seen from Examples 6-8, adding a smoke enhancer can improve smoke density and stability, thereby improving the consumer's taste and satisfaction. The amount of smoke enhancer added will affect the above indicators.
