Problems solved by technology

[0002] New tobacco products, such as electronic cigarettes, electric heating new cigarettes, fuel-heating tobacco products, chewing tobacco, snus, snuff, and tobacco spray products, all have a common feature. The consumption process does not pass through tobacco combustion. Difficult to be recognized by consumers
A certain amount of tobacco extract is added to the new tobacco to meet consumers' demand for cigarettes. Generally, tobacco extracts are extracted by dissolving, and the extract contains a certain amount of macromolecular compounds, especially for electronic cigarettes, electric Heating new cigarettes, fuel-heating tobacco products, etc., it is difficult to atomize and generate smoke at a lower temperature, and the aroma substances are difficult to evaporate, which will lead to problems such as blockage of the atomizer

Embodiment 1

[0018] Take 500g of flue-cured tobacco leaves after appropriate moisture treatment, shred treatment, add cellulase treatment, the treatment equivalent is 40u / g, dissolve cellulase in water, spray evenly on the shredded tobacco, and place the shredded tobacco after spraying in a sealed container In, put into the adjusted constant temperature and humidity chamber (temperature 50 ℃, humidity 25%). Store for 24 hours. After the enzymatic hydrolysis, it was quickly put into an oven adjusted to 80°C for 20 minutes to inactivate the enzyme, and the enzymatic hydrolyzed shredded tobacco was ground into powder.

[0019] Soak shredded tobacco ground into powder in 1500 mL of 95% ethanol (mass fraction, the same below), heat to reflux for 2 hours, filter and concentrate the filtrate to remove ethanol to obtain tobacco concentrate.

[0020] Take the concentrated concentrate, place it in a vacuum distillation equipment, carry out vacuum distillation on the concentrate, slowly heat, the sy...

Embodiment 2

[0024] Take 500g of flue-cured tobacco leaves after appropriate moisture treatment, shred treatment, add cellulase treatment, the treatment equivalent is 40u / g, dissolve cellulase in water, spray evenly on the shredded tobacco, and place the shredded tobacco after spraying in a sealed container In, put into the adjusted constant temperature and humidity chamber (temperature 30 ℃, humidity 25%). Store for 10 hours. After the enzymatic hydrolysis, it was quickly put into an oven adjusted to 70° C. for 30 minutes to inactivate the enzyme, and the enzymatic hydrolyzed shredded tobacco was ground into powder.

[0025] Add 2000mL of deionized water to the cut tobacco that has been ground into powder, and extract it with ultrasonic waves at 45°C for 3 hours. After filtering, the filtrate is concentrated to remove the solvent to obtain a certain concentration of tobacco concentrate.

[0026] Take the tobacco concentrate, place it in a vacuum distillation equipment, carry out vacuum d...

Abstract

The invention provides a preparation method and application of tobacco extract easy to atomize at the low temperature. The preparation method of the tobacco extract comprises the steps that tobacco serves as the raw material, moisture regaining and shredding treatment are conducted, and enzymolysis, solvent extraction and reduced pressure distillation are conducted, so that the tobacco extract is obtained, and then according to the characteristics of tobacco to which the tobacco extract is to be added, the tobacco extract is compounded into different ratios and added to different novel cigarettes. The preparation method and application of the tobacco extract are reasonable in design and simple in method, the tobacco extract is atomized easily at the low temperature, tobacco aroma is maintained, the aroma amount is sufficient, after the tobacco extract is atomized, no black residue is generated, no charring smell is generated, when the tobacco extract is applied to novel tobacco products, characteristic aroma of tobacco is made to be clearer, and the acceptability of the novel tobacco products is improved.
