Problems solved by technology

[0002] At present, products containing tobacco substances such as chewing tobacco, snus, snus, electric heating tobacco products, fuel heating tobacco products, tobacco spray products and electronic cigarettes all have a common feature, that is, the taste is similar to that of traditional cigarettes or cigars. The taste of cigarettes is very different, it is difficult for consumers to recognize
At the same time, the aroma of tobacco extract is also far from the taste of smoking and burning cigarettes or cigars. Tobacco and other products provide sufficient burnt aroma, burnt sweet aroma, light fragrance, light sweet aroma, woody aroma and other aromas
[0003] At present, various research teams have focused on adding various natural aroma substances to achieve the purpose of imitating the taste of cigarettes or cigars, but the current method of adding aroma substances is still difficult To achieve the purpose of imitating the taste of cigarettes or cigars
In addition, some tobacco products have the disadvantage that the flavor components are difficult to last

Embodiment 1

[0034] Tobacco leaves (75g) were soaked in 450mL ethanol (95%), 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.

[0035] Take the concentrate (6g) and place it in a 50mL eggplant-shaped bottle, equipped with a reflux condenser, under a nitrogen atmosphere, bury the eggplant-shaped bottle in a sand bath, heat the sand bath, and raise the temperature by 5°C per minute. Heat the sand bath from 150°C to 500°C, stop heating and cool down, and the tobacco extract is in the eggplant-shaped bottle.

Embodiment 2

[0037] Soak shredded tobacco (50g) in 100mL of 1% hydrochloric acid solution, keep it for 1 hour, filter, wash shredded tobacco with clear water to neutrality, put shredded tobacco in 300mL ethanol (95%) after filtering, and filter under 50kHz ultrasonic wave With assistance, extract at room temperature for 3 hours, filter and concentrate the filtrate to remove ethanol to obtain a concentrate.

[0038] Take the concentrate (1g) under the atmosphere of nitrogen / air (volume ratio 20:1), according to the heating method in Example 1, equipped with a reflux condenser, and start heating from 150°C at a rate of 5°C per minute When the temperature reaches 400°C, stop heating and cool down to obtain tobacco extract.

Embodiment 3

[0040] Tobacco leaves (10kg) were soaked in 50L 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.

[0041] Take the concentrate (800g) and put it in the molecular distillation equipment, use a vacuum of 0.1Pa, the distillation temperature is 100°C, the temperature of the circulating cooling liquid is 0-5°C, and the distillate is collected. Take the distillate (5g) and place it in a 50mL round-bottomed bottle, and equip it with a reflux condenser, replace the air in the system with nitrogen, then put the round-bottomed bottle into a sand bath preheated to 300°C, After heating to reflux for 2 hours, the sand bath was removed, and the tobacco extract was obtained after cooling to room temperature.

Abstract

The invention belongs to the tobacco field and discloses a preparation method for tobacco extract. The preparation method for the tobacco extract includes steps that 1) placing tobacco raw material in solvent to extract, wherein the solvent is one or more of hydrochloric acid, water, sulfuric acid, glycol and ethanol; 2) heating at 100 to 500 degrees centigrade, wherein the heating is performed in the mixed atmosphere of which the volume ratio of nitrogen to air and / or oxygen is 100: 0-10. According to the preparation method for the tobacco extract and the application of the tobacco extract, the tobacco extract is richer in fragrance than the tobacco before processing, the tobacco extract is used for chewing tobacco, mouth tobacco, snuffing tobacco, electric heating type tobacco product, fuel heating type tobacco product, tobacco atomizing product, electronic cigarette and the like, and the tobacco extract can enable the products to be greatly closer to the traditional cigarette flavor. When the tobacco extract is used for perfuming cigarette, the tobacco extract plays roles of increasing the thick sense of smoke, making the smoke fine and smooth, enriching the tobacco fragrance and the like.
