Example Embodiment
[0013] Example 1
[0014] Take 1 part of flue-cured tobacco shreds into the extraction container, then add 15 parts of 40% ethanol aqueous solution, soak at 30 ℃ for 48 hours, and filter under reduced pressure to obtain the tobacco extract. After the extract is evaporated to remove ethanol under reduced pressure, it is freeze-dried to obtain a flue-cured tobacco-type solid tobacco extract.
Example Embodiment
[0015] Example 2
[0016] Take 3 parts of flue-cured tobacco, 1 part of burley tobacco and 1 part of oriental tobacco and mix them into the extraction vessel, then add 50 parts of 60% ethanol aqueous solution, soak at 40 ℃ for 24 hours, and filter under reduced pressure to obtain tobacco extract liquid. After evaporating the extract under reduced pressure to remove ethanol, it is spray-dried to obtain a mixed solid tobacco extract.
Example Embodiment
[0017] Example 3
[0018] 100 parts of starch polysaccharide, 30 parts of flue-cured tobacco solid tobacco extract, 15 parts of glycerol, 15 parts of Mg(OH) 2 Add deionized water, fully disperse and dissolve, gelatinize at 80 ℃ for 1 h, then degas under reduced pressure for 20 min to obtain a film-forming liquid. Using the casting method, spread the film-forming liquid on a glass template to form a film, and dry it at 35 ℃ for 48 h before releasing the film. After the prepared film is equilibrated in an environment with a temperature of 22 ℃ and a relative humidity of 60% for 48 hours, a tobacco film suitable for heating non-combustion tobacco products is obtained. The tobacco film has good smoke release performance in the heating and non-combustion state, and the released smoke presents obvious flue-cured tobacco style characteristics, and has good satisfaction and comfort.
