Description
Technical Field
The invention belongs to the technical field of heating cigarettes, and particularly relates to a high-molecular latent-fragrance slow-release material and application thereof in heating cigarettes.
Background
In recent years, the sales of traditional cigarettes have been decreasing due to the continuing concerns about smoking and health issues. Meanwhile, a plurality of novel tobacco products enter the visual field of people, the heating cigarette is used as a novel cigarette product, the smoking mode of the novel cigarette product is most similar to the sensory quality of the novel cigarette product and the traditional cigarette, and meanwhile, the harm of smoking the traditional cigarette can be greatly reduced, so that the novel cigarette product becomes the most potential development direction of the tobacco industry.
In the process of smoking, the traditional cigarette releases nicotine and flavor substances through slow combustion of the tobacco shred sections, so that the sensory difference of consumers before and after smoking is relatively small. The heating cigarette is to heat the tobacco sheet by a heating appliance to release substances such as nicotine and the like to meet the sensory requirements of consumers, and the tobacco sheet is in a continuous overall heating state, so that the release of small-molecule flavor substances with strong volatility, such as alcohol flavors, acid flavors and phenol flavors, is difficult to keep consistent, and the problem of inconsistent mouth-to-mouth smoking taste of the heating cigarette in the smoking process is more prominent.
By pro-fragrance is meant a compound which is not itself fragrant or less fragrant, but which is capable of degrading or splitting during aging or heating to produce a fragrance. The latent fragrant substance has low volatility and strong stability, and the addition of the latent fragrant substance in the heated cigarette is an effective way for solving the existing problems of the heated cigarette. However, the aroma substances for cigarettes studied and used at present, such as glycoside aroma compounds, sugar ester aroma compounds and sugar amine aroma compounds, are all small-molecule aroma substances, and the steps of synthesis and purification are complex, so that the cost is high, and the large-scale application of the aroma substances is hindered.
Therefore, the development of a novel latent fragrant substance which can be applied in a large scale, the innovation of the use mode of the latent fragrant substance in the heating cigarette and the effective improvement of the consistency of the smoking flavor before and after smoking of the heating cigarette are still the current technical difficulties.

Further, the polymer type latent fragrance slow-release material is cracked at the temperature of 200-300 ℃ to release small molecule fragrance substances.
A heated cigarette, which uses the polymer type latent-fragrance sustained-release material.
Further, the polymer type latent-fragrance slow-release material is prepared into a film-shaped material by a processing mode of solution molding or hot melt molding, and then the film-shaped latent-fragrance slow-release material in a tobacco shred shape is prepared and added into a tobacco rod of a heated cigarette.
Furthermore, the adding proportion of the latent-aroma slow-release material in the shape of the cut tobacco in the tobacco rod of the heating cigarette is 0.05-2 wt%.
The invention has the beneficial effects that:
the invention takes natural high molecular material and micromolecule perfume materials such as alcohol perfume, acid perfume and phenol perfume as reaction substrates, and prepares the high molecular latent perfume slow-release material through esterification reaction.
The polymer type latent-fragrance slow-release material has good processing performance, can be prepared into a film-shaped material by a solution forming or thermal forming mode, and then is shredded into a tobacco shred-shaped latent-fragrance slow-release material which is directly added into tobacco shreds for heating cigarettes. The use mode of the high molecular type latent fragrant substance provided by the invention is different from that of a small molecular type fragrant substance or latent fragrant substance, and the high molecular type latent fragrant substance has better processing convenience.
Meanwhile, the polymer type latent-fragrance slow-release material can uniformly crack and release corresponding small-molecule spice substances at the temperature of 200-300 ℃, and when the polymer type latent-fragrance slow-release material is used for heating cigarettes, the taste-per-mouth consistency of the heated cigarettes in the smoking process can be effectively improved, the miscellaneous gas of the heated cigarettes is reduced, the mouth feel is improved, and the sensory quality of the heated cigarettes is improved.
