Embodiment 1

[0020] Weigh 100g of 60-80mesh tobacco stem powder into a 1000ml round bottom flask, bake in a 90°C oven for 6 hours, add 500ml of cyclohexane, and place it in a 90°C water bath for reflux extraction for 2 hours. Filter the extract while hot into another 1000ml round bottom flask, add 500ml cyclohexane again, and repeat the extraction twice. Combine the extracts. The extract was concentrated on a rotary evaporator with a vacuum degree of 300mbar and a water bath temperature of 50°C until cyclohexane-free, and then concentrated under reduced pressure to 100mbar until no liquid was evaporated to obtain a crude extract. Add 20g of ethanol and propylene glycol mixed solvent with a volume ratio of 1:9, heat and dissolve at 50°C for 2 hours, cool to room temperature, and centrifuge at a speed of 8000 rpm for 2 minutes. Smoke liquid.

Embodiment 2

[0022] Weigh 100g of 60-80mesh tobacco leaf powder into a 1000ml round bottom flask, bake in an oven at 150°C for 1 hour, add 600ml of dichloromethane, and stir at room temperature for 2 hours. Filter the extract into another 1000ml round bottom flask, add 500ml cyclohexane again, and repeat the extraction twice. The extracts were combined, concentrated on a rotary evaporator with a vacuum degree of 900 mbar and a water bath temperature of 50° C. to no dichloromethane, and then gradually reduced to 70 mbar and concentrated for 20 minutes to obtain a crude extract. Add 100g of a mixed solvent of ethanol, propylene glycol, and glycerin with a volume ratio of 1:5:5, heat and dissolve at 70°C for 10 minutes, cool to room temperature, and centrifuge at a speed of 5000 rpm for 10 minutes, and the obtained clear liquid is the product of the present invention. The e-cigarette liquid;

Embodiment 3

[0024] Weigh 100g of 60-80mesh tobacco stem powder into a 1000ml round bottom flask, bake in an oven at 100°C for 3 hours, add 500ml of ethyl acetate, and stir at room temperature for 4 hours. Filter the extract into another 1000ml round bottom flask, add ethyl acetate to 500ml according to the amount of the filtrate, continue stirring and extracting at room temperature for 1 hour, and repeat the extraction twice. The extracts were combined, concentrated on a rotary evaporator with a vacuum degree of 700mbar and a water bath temperature of 50°C until no ethyl acetate was present, and then gradually reduced to 70mbar and concentrated for 20 minutes to obtain a crude extract. Add 20ml of a mixed solvent of ethanol, propylene glycol, and glycerin with a volume ratio of 1:5:5, heat and dissolve at 60°C for 10 minutes, cool to room temperature, and centrifuge at a rate of 6000 rpm for 5 minutes. The obtained clear liquid is the present invention. The e-cigarette liquid.

Abstract

The invention discloses a preparation method for electronic cigarette juice having a baking fragrant characteristic. The method is characterized in that the electronic cigarette juice is prepared by baking cigarette raw materials in high temperature for a period of time; after generating materials having the baking fragrant characteristic, extracting by using a solvent; drying the solvent from obtained extracting solution by distillation to obtain extractum; then heating and dissolving the extractum by using a mixed solvent of ethyl alcohol, propylene glycol and glycerinum in a certain proportion. The cigarette raw materials are pre-baked in high temperature before being extracted, so that the prepared cigarette juice has the characteristic fragrance component of the cigarette baking; the extracting and extractum dissolving processes are provided with a certain temperature to be in favour of generating Maillard reaction; more aroma components are generated; the sensory quality can be improved.

Description

technical field [0001] The invention relates to the preparation of e-cigarette liquid, in particular to a method for preparing e-cigarette liquid with the characteristic of roasted aroma, and belongs to the technical field of tobacco chemical industry. Background technique [0002] As a non-combustible cigarette substitute, electronic cigarettes are gradually being accepted and loved by smokers due to their many advantages such as non-combustion, no tar and various carcinogens, and no "second-hand smoke" hazards. In addition, it has no open flame, no by-products of combustion, no pollution to the public environment, and no fire hazard. It is a healthy cigarette substitute with far-reaching significance for public health and environmental protection. However, the taste of e-cigarette products is sweet and the taste of smoke is light, which is far from the feeling of smoking traditional cigarettes, which is an important factor restricting the development of e-cigarettes.
