Description
Technical Field
The invention relates to the technical field of heating non-combustible cigarettes and traditional cigarettes, in particular to an effective moisture-proof aerosol former precursor composition.
Background
The moisture absorption/reversion of the tobacco products during the transportation and storage process brings unpleasant visual experience to consumers, and a series of safety hazards exist due to further mildew caused by the moisture absorption/reversion. The non-combustible cigarette is heated (including particle type non-combustible cigarette) by using a special heat source to heat tobacco/particle materials (below 500 ℃ or even lower), the tobacco materials are not combusted, and harmful chemical components (such as carbon monoxide, hydrocarbon substances and the like) and biotoxicity of smoke are greatly reduced. In order to ensure a sufficient amount of smoke, most of the existing cigarette products which are not heated and combusted adopt alcohol which is easy to absorb moisture such as glycerin (CN 106714590B) as an aerosol forming agent (atomizing agent). However, the aerosol generating agents are generally characterized by strong hygroscopicity, high requirements on production and storage of products, and high rewinding difficulty of finished products, and meanwhile, excessive moisture absorbed by tobacco or non-tobacco particle products in the process can not only cause the cigarettes to get damp/mildew, but also reduce the release amount of smoke generated by heating the non-burning cigarettes, thereby seriously affecting the experience of consumers. Although some documents (CN 108601390 a; CN 111386051 a) report the addition of polyol esters (such as triacetin) or fatty acid esters (such as dimethyl dodecanedioate) as aerosol formers, they generally have boiling points greater than alcohols such as glycerol, and thus their smoke levels can be predicted to be less than alcohols such as glycerol, which can lead to an undesirable experience for the consumer. Furthermore, these polyol esters or fatty acid esters are not presently reported to have a moisture barrier effect, but are reported to impart other properties, for example CN 111386051 a points out that tobacco containing small amounts of triglycerides promotes the release of nicotine at elevated temperatures compared to tobacco without the addition of triglycerides. At present, tobacco products using glycerin as the main component of aerosol forming agent, especially cigarette products which are not burnt under heating, still suffer from moisture regain/mildew due to cigarette moisture absorption.

The above reaction does not occur at a relatively low temperature (e.g., below 50 ℃). Compared with the traditional aerosol taking the main components as alcohols such as glycerol, the water absorption of cigarettes (tobacco sheets and cigarettes which are not heated and combusted) using the aerosol former composition is greatly reduced in the transportation and storage processes, so that the aerosol former composition can play a role in effectively preventing damp, and effectively avoids the problems of cigarette moisture regain and mildewing caused by the large moisture absorption of alcohol substances in the transportation and storage processes; meanwhile, the aerosol smoke amount generated by the in-situ reaction can be maintained at a higher level for a longer time in the using process of the cigarette, the smoke is not obviously reduced, the smoke is sufficient (the average smoke amount of the tobacco sheets can reach 5.35 mg/mouth-6.18 mg/mouth), the number of suction openings can reach 17-22 mouths, and the improvement is obvious compared with the prior art. The precursor composition of the moisture-proof aerosol forming agent can be directly applied to the field of tobacco, and particularly can be used as an aerosol forming agent for cigarette which is not combusted by heating.
(2) The components in the moisture-proof aerosol former composition are compatible with the tobacco field, have wide and easily-obtained sources, and can be directly used in the tobacco field, in particular the field of heating non-combustion cigarettes.
(3) The moisture-proof aerosol former composition can generate corresponding alcohol through the in-situ reaction of hydrophobic alcohol ester and an alkaline compound in a temperature range for heating non-burning cigarettes to use, further atomizes to generate aerosol, and ensures that enough smoke quantity is generated for a long time in the cigarette using process.
(4) The moisture-proof aerosol former composition disclosed by the invention can continuously generate sufficient smoke quantity through in-situ reaction in a temperature range for heating a non-combustible cigarette by matching the specifically screened hydrophobic alcohol ester with the specifically screened alkaline compound and combining the specific proportion of the hydrophobic alcohol ester and the specifically screened alkaline compound, so that the problems of moisture absorption of the heated non-combustible cigarette and smoke quantity reduction caused by the moisture absorption of the heated non-combustible cigarette are solved, the cigarette prepared from the moisture-proof aerosol former composition is moderate in smoke quantity and suction opening number, the smoke is strong, the nasal cavity is not obviously stimulated, and the comfort is strong. On the basis, the alcohol is added, and the relative proportion of the hydrophobic alcohol ester and the alcohol is controlled, so that a synergistic effect can be generated, the average smoke amount of the tobacco sheet is further improved, and meanwhile, the moisture absorption rate of the tobacco sheet is slightly improved but still below 19 percent, and is obviously lower than about 30 percent of the moisture absorption rate of the tobacco sheet of the traditional aerosol taking the alcohol such as glycerol as the main component.

Formula of moisture absorption rate: moisture value after 7 days-initial moisture value.
The method for testing the smoke quantity of the tobacco sheets comprises the following steps: taking the above groups of cigarettes (with the mass of 0.67-0.68 g) to perform smoke quantity test in the same smoking machine, setting the temperature to be 350 ℃, preheating the smoking machine for 15 seconds before each group of cigarettes is inserted into the smoking machine, and immediately performing smoke quantity data collection, wherein the parameters are set to be consistent as follows: the smoking capacity of each mouth of each group of 6 mouths is 55ml, the smoking time is 2 seconds, the interval time of each mouth is 30 seconds, the average value of the smoke quantity of each mouth can be obtained, and the larger the numerical value is, the larger the smoke quantity is.
Human sensory evaluation of tobacco sheets: the above-mentioned each group of cigarettes are inserted into the smoking set for heating and smoking (dark evaluation), and the main concern is that the indexes are: the amount of smoke, the number of suction openings, the stiffness of the smoke and the comfort are analyzed and evaluated by a statistical test method.
To further demonstrate that the groups of aerosol formers do not react with the alcohol ester and the alkaline salt to form an alcohol that is hygroscopic at room temperature (i.e., during storage and transportation), the mass percent of the corresponding alcohol, designated as W, was determined by gas chromatography after each group of aerosol compositions was placed in a closed container at 40 ℃ for 7 days.
