Description
Technical Field
The invention relates to the field of novel tobacco products, in particular to a dynamic extraction treatment method suitable for tobacco shreds in a heating and non-combustion state.
Background
The research and development of novel tobacco products are one of the most recently determined major items by the national bureau, representative heating non-combustible products in the international market at present are divided into electric heating type products and carbon heating type products, and the novel tobacco products are characterized in that cigarettes are not directly combusted, but smoke is released by heating tobacco materials, so that harmful ingredients generated by high-temperature combustion cracking of tobacco are reduced, and harmful ingredients of mainstream smoke are reduced. The research on the heating section matrix which is one of the key technologies of the novel tobacco products is particularly important, and mainly focuses on solving the problem that the tobacco extract can be rapidly released from the matrix under the low-temperature condition, so that a consumer can achieve the same physiological strength as that of the conventional cigarette during smoking and burning, and less harmful ingredients are released. Foreign tobacco companies have developed technical research for nearly 30 years around new tobacco products, with comprehensive layout and planning in the industry and associated product and technical reserves. At present, the mainstream materials of the heating section of the heating unfired product in the international market are all specially-made reconstituted tobacco leaves, and the traditional tobacco shreds are not used.
The development of smokeless tobacco products is still in the starting stage in China, the core technology is very few, no independently researched smokeless tobacco products exist in the domestic market at present, patent application is concentrated on the aspects of electric heating appliance design and the like, the traditional tobacco shreds are used for heating and non-burning after being subjected to supercritical treatment and have not been reported, and the traditional cigarette is mainly concentrated on harm reduction, tar reduction, aroma enhancement and moisture preservation of traditional cigarettes; secondly, the traditional tobacco shred shape is used for heating and non-burning, and is not reported, and basically takes the improvement of the structure of the tobacco raw material or the preparation of carriers by the tobacco raw materials with different shapes as the main material. The heating effect evaluation and sensory evaluation on the conventional cigarette are found that the conventional cigarette has low smoke concentration and obvious water stain on cigarette paper in a heating and non-combustion state, and sensory evaluation shows that the smoke at the suction end of the filter tip is excessively hot. The process of preparing the tobacco material is particularly important in the heating zone material aspect, and can directly affect the smoke release in a heating non-combustion state. Currently, the design aspects of the heating section materials mainly relate to tobacco raw materials and tobacco extracts, and the most core materials are tobacco (including cut tobacco, tobacco fragments, reconstituted tobacco leaves, tobacco particles, tobacco powder and the like) or key component extracts (such as nicotine, tobacco flavor substances and the like) in the tobacco. The traditional cut tobacco provided by the invention is subjected to a treatment method designed by one or two of supercritical static extraction, supercritical dynamic extraction or water treatment, then glycerin and propylene glycol are added, then the traditional cut tobacco is placed in a humidity balance chamber at a certain temperature for a certain time, and finally the treated cut tobacco is subjected to sample rolling. When the cigarette is used, the processed cigarette can be directly placed in a heating non-combustion appliance for smoking evaluation, compared with untreated tobacco shreds, the tobacco shreds with loose structures and certain water content can better adsorb glycerin and propylene glycol, the tobacco shred balance time is shortened, the smoking smoke concentration is obviously improved in a heating non-combustion state, the smoke scalding and the sour taste are obviously reduced, and the cigarette paper has no obvious water stain in appearance. The method for treating the tobacco shreds in the non-combustible heating state has important significance for domestic research and development of tobacco products which are non-combustible by heating, and simultaneously provides a new idea for the industry in the aspect of research and development of commonness of traditional tobacco shred treatment.

Preferably, the moisture content of the tobacco raw material in the step 1) is 10-20%.
Preferably, the moisture content of the cut tobacco raw material obtained in the step 2) is 1-6%.
Preferably, the balancing treatment method in the step 3) is to immediately place the cut tobacco uniformly mixed with the humectant in an environment with the temperature of 20 ℃ and the relative humidity of 40-60% for balancing for 24-48h to obtain the traditional cut tobacco raw material suitable for being heated and not combusted.
Preferably, the humectant is selected from propylene glycol, glycerol or a mixed solvent of the two solvents, and the content of the humectant is 5-30% of the total amount.
Preferably, the moisture content of the final cut tobacco obtained after the balancing in the step 3) is 11.5-12.5%.
The dynamic extraction mode of the invention is as follows: namely, a certain amount of entrainer is added into an extraction kettle at a certain pressure and temperature, and CO is in a supercritical state2And (4) taking the extract into a separation kettle while taking out, separating the extract, taking out the extract from the separation kettle after reaching the extraction time, and obtaining the extracted cut tobacco by the extraction kettle.
Another object of the present invention is to provide a cut tobacco produced by the above dynamic extraction treatment method suitable for cut tobacco in a state of being non-combustible by heating.
And (3) rolling the traditional cut tobacco processed in the step 3) into the shape of a traditional cigarette, and directly placing the traditional cigarette in a heating non-combustible appliance for evaluation.
Compared with the traditional untreated tobacco shred added with the humectant, the traditional treated tobacco shred provided by the invention has the advantages that the smoke is rapidly released, the smoke concentration is obviously improved, the sensory quality is obviously improved, the scalding and sourness of the smoke are obviously reduced under the condition that the heating temperature is lower than 250 ℃, and the cigarette paper has no obvious water stain in appearance.
By adopting the technical scheme, the invention has the following beneficial effects:
the heating effect evaluation and sensory evaluation on the conventional cigarette are found that the conventional cigarette has small smoke release amount and obvious water stain on cigarette paper in a heating and non-burning state, and the sensory evaluation shows that the smoke at the suction end of the filter tip is excessively hot and is accompanied with obvious sour taste. The traditional cut tobacco provided by the invention is firstly subjected to supercritical dynamic extraction treatment, and the treated cut tobacco is obtained after the cut tobacco is extracted for a certain time. And adding glycerol and propylene glycol, then placing in a humidity balance chamber at a certain temperature for a certain time, and finally rolling the processed tobacco shreds into samples. When the cigarette is used, the processed cigarette can be directly placed in a heating non-combustion appliance for suction evaluation, compared with unprocessed tobacco shreds, the tobacco shreds subjected to supercritical dynamic extraction are extracted due to endogenous substances of the tobacco shreds, and meanwhile, the internal structure is changed, so that the cigarette is looser, the moisture content is lower, glycerin and propylene glycol can be better adsorbed, the smoke concentration is obviously improved when the cigarette is sucked in a heating non-combustion state, and the smoke scalding and the sour taste are obviously reduced.
