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 immersed in 450 mL ethanol (95%), and with the assistance of ultrasound, extracted at room temperature for 3 hours. After filtration, 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, and bury the eggplant-shaped bottle in a sand bath under a nitrogen atmosphere. Heat the sand bath at a rate of 5°C per minute. Heat the sand bath from 150°C to 500°C, stop heating and cooling, and the tobacco extract is in the eggplant-shaped bottle.

Embodiment 2

[0037] Soak the cut tobacco (50g) in 100mL 1% hydrochloric acid solution, keep it for 1 hour, filter, wash the cut tobacco with clean water to neutrality, after filtering, place the cut tobacco in 300mL ethanol (95%), filter it with 50kHz ultrasonic wave With the aid of extraction at room temperature for 3 hours, after filtration, the filtrate was concentrated to remove ethanol to obtain a concentrate.

[0038] Take the concentrate (1g) in a nitrogen / air (volume ratio 20:1) atmosphere, follow the heating method in Example 1, with a reflux condenser, and heat up at a rate of 5°C per minute, starting from 150°C When the temperature reaches 400°C, the heating and cooling are stopped, and the tobacco extract is obtained.

Embodiment 3

[0040] The tobacco leaves (10 kg) were immersed in 50 L ethanol (95%), and with the assistance of ultrasound, the mixture was extracted at room temperature for 3 hours. After filtration, the filtrate was concentrated to remove the ethanol to obtain a concentrate.

[0041] Take the concentrate (800g) and place it in a molecular distillation device, use a vacuum of 0.1 Pa, a distillation temperature of 100°C, and a circulating cooling liquid temperature of 0-5°C, and collect the distillate. Take the distillate (5g) and place it in a 50mL round-bottom flask, and equip it with a reflux condenser, replace the air in the system with nitrogen, and then place the round-bottom flask in a sand bath that has been preheated to 300°C. After heating and refluxing for 2 hours, the sand bath is removed, and the tobacco extract is obtained by 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.

Description
