Problems solved by technology

However, the paper-making method sheet itself is difficult to overcome the shortcomings of low smoke concentration and low strength. Using it in cigarette products will reduce the smoke concentration and strength, and cannot give consumers a sense of satisfaction.
Chinese patent CN105029668A uses flue-cured tobacco stems, air-dried tobacco stems, flue-cured tobacco leaf fragments, and air-dried tobacco leaf fragments as raw materials to prepare high-concentration, high-strength flakes through papermaking sheet technology. However, since air-dried tobacco also contains a lot of miscellaneous gases, proteins, polysaccharides and other substances at the same time, there will be problems such as introducing miscellaneous gases and irritation into the slices when used in large quantities according to the above-mentioned patented method. reduced its quality

Embodiment 1

[0015] A method for preparing a cigarette aroma material for tobacco sheets, comprising the steps of:

[0016] (1) Extraction process: take a certain amount of sun-cured red tobacco leaves, add 20% ethanol-water solution to the tobacco raw material according to the mass ratio of material to liquid of 1:7, heat and condense under the condition of 80 ° C for 3 hours, and collect the extract; then Then add water to the tobacco raw material according to the mass ratio of material to liquid 1:7, heat and condense and reflux for 3 hours at 100°C, and collect the extract; combine the extracted extracts collected twice for filtration, and carry out vacuum concentration at 60°C until The density of the concentrate reaches 1.2g / cm 3 ; Precipitate the concentrated solution with 95% ethanol at a ratio of 1:3 for 5 hours, collect the precipitated solution, filter it and concentrate it in vacuum at 60°C until the density of the concentrated solution reaches 1.1g / cm 3 ; add a certain amount...

Embodiment 2

[0020] A method for preparing a cigarette aroma material for tobacco sheets, comprising the steps of:

[0021] (1) Extraction process: take a certain amount of Burley tobacco leaves, add 30% ethanol-water solution to the tobacco raw material according to the mass ratio of material to liquid of 1:10, heat and condense and reflux for 4 hours at 80° C., and collect the extract; Then add water to the tobacco raw material according to the mass ratio of solid to liquid 1:10, heat and condense to reflux for 4 hours at 100°C, and collect the extract; combine the extracts collected twice to filter, and vacuum concentrate at 60°C, Until the density of the concentrated solution reaches 1.2g / cm3; the concentrated solution and 95% ethanol are subjected to alcohol precipitation at a ratio of 1:4 for 8h, the alcohol precipitated solution is collected, filtered and concentrated in vacuum at 60°C until the concentrated solution reaches a density of 1.1g / cm3 cm 3 ; Add a certain amount of prop...

Embodiment 3

[0025] A method for preparing a cigarette aroma material for tobacco sheets, comprising the steps of:

[0026] (1) Enzymolysis process: get 5% cellulase solution and spray on the surface of a certain amount of Burley tobacco leaves, the solution consumption accounts for 10% of the tobacco leaf weight, the enzymolysis temperature is 30 ℃, the pH value is 7, and the enzymolysis time is 8h.

[0027] (2) Extraction process: add 30% ethanol-water solution to the tobacco raw material of the Burley tobacco leaves after enzymolysis according to the mass ratio of material to liquid 1:10, heat and condense and reflux at 80°C for 4 hours, collect and extract liquid; then add water to the tobacco raw material according to the mass ratio of material to liquid 1:10, heat and condense and reflux for 4 hours at 100°C, and collect the extract; combine the extracts collected twice to filter, and carry out vacuum at 60°C Concentrate until the density of the concentrate reaches 1.2g / cm 3 ; The ...

Abstract

The invention provides a preparation method of tobacco-aroma matters for tobacco sheets.The preparation method includes using an extraction-molecular distillation combined technology for separating purified tobacco raw materials to obtain the strongly-satisfying tobacco-aroma matters.By the extraction-molecular distillation combined technology, nicotine and characteristic tobacco aroma light constituents in tobacco extract are enriched and purified, and macromolecular substances such as cellulose, polysaccharide, pectin and protein adverse to smell absorption can be further removed.The tobacco sheets prepared from the tobacco-aroma matters are capable of remarkably increasing smoke concentration, strength and aroma of cigarette products and make smokers feel satisfied and comfortable strongly.

Description

technical field [0001] The invention relates to the field of tobacco sheet processing, in particular to a preparation method and application of tobacco sheet tobacco incense. Background technique [0002] As people pay more and more attention to the safety of smoking, papermaking sheet technology has been widely recognized by the tobacco industry at home and abroad as an effective means to reduce the tar content of cigarette products. However, it is difficult for the paper-making sheet itself to overcome the disadvantages of low smoke concentration and low strength. Using it in cigarette products will reduce the smoke concentration and strength, and cannot satisfy consumers. Chinese patent CN105029668A uses flue-cured tobacco stems, air-dried tobacco stems, flue-cured tobacco leaf fragments, and air-dried tobacco leaf fragments as raw materials to prepare high-concentration, high-strength flakes through papermaking sheet technology. However, since air-dried tobacco also con...
