Embodiment 1

[0035] Tobacco leaves (75g) were soaked in 450mL of 95% ethanol (mass fraction, the same below), and extracted at room temperature for 3 hours with the assistance of ultrasonic waves. After filtering, the filtrate was concentrated to remove ethanol to obtain a concentrate.

[0036] Take the concentrate (6 g) and place it under a nitrogen atmosphere, start heating from 150°C to 340°C, and collect the distillate at a rate of 5°C per minute. When no obvious substance distills out, replace the gas above the distillation residue with air, continue the distillation and increase the temperature to 400°C at a rate of 5°C per minute, and stop heating when there is no obvious liquid distillate.

[0037] The resulting distillates were combined to obtain fractions at 150-400°C.

[0038] In the same preparation method, the distillates are not combined and marked as 150-340°C fraction and 340-400°C fraction.

Embodiment 2

[0040] Add tobacco leaf (1kg) and 50mL ethanol (95%) in the supercritical extraction equipment, under the extraction pressure of 40MPa, and the extraction temperature of 50 ℃, use carbon dioxide to extract 3 hours, then the extract containing ethanol that obtains is concentrated and removed ethanol to obtain a concentrate. Take the concentrate (6g) under the atmosphere of nitrogen / air (volume ratio 20:1), and start heating at 150°C to 400°C, at a rate of 5°C per minute, when there is no obvious distillate, stop heating. The obtained distillate is the tobacco distillate.

Embodiment 3

[0042] Tobacco leaves (50g) were soaked in 300mL ethanol (95%), extracted at room temperature for 3 hours with the assistance of ultrasonic waves, filtered, and the filtrate was concentrated to remove ethanol to obtain a concentrate. Take the concentrate (6g) under a nitrogen atmosphere, and start heating from 150°C to 400°C, at a rate of 5°C per minute, and stop heating when there is no obvious distillate. The obtained distillate is the tobacco distillate.

Abstract

The invention discloses tobacco distillate, and preparation and application thereof. The tobacco distillate is obtained through distilling tobacco raw material. A preparation method for the tobacco distillate includes steps that 1) placing the tobacco raw material in solvent to extract, wherein the solvent is ethanol solution with mass fraction 40-99%; 2) heating the material of the step 1), and gathering the distillate of which the temperature is 150 to 400 degrees centigrade. The distillate is obtained through distilling tobacco material under a gas atmosphere in a certain temperature range, and the distillate has full-bodied scorch aroma, faint scent, elecampane and the like tobacco aroma.

Description

technical field [0001] The invention belongs to the field of tobacco, and in particular relates to a preparation method and application of remanufactured tobacco products. Background technique [0002] Tobacco has a complex and changeable aroma, which stimulates the nerves, and tobacco products have a very wide consumer market. Shredded cigarettes are the most common tobacco products. Tobacco products also include chewing tobacco, snus, snus, electric heating tobacco products, fuel heating tobacco products, tobacco spray products and electronic cigarettes, but they all have a common feature, that is, the taste is similar to that of traditional cigarettes or cigars. The taste is very different, and it is difficult for consumers to recognize it. At the same time, the aroma of tobacco extract is also far from the aroma of smoking burning cigarettes or cigars, and it is difficult to provide sufficient complex and multi-layered aromas such as burnt aroma, burnt sweet aroma, lig...
