The present invention proposes a method for preparing electronic cigarette smoke liquid, which is characterized in that it comprises the following steps: (1) preparing a deep eutectic solvent: reacting choline chloride with different alcohols according to a certain molar ratio, and the reaction temperature is 40-80°C, the reaction time is 1-6 hours, and the resulting colorless and transparent liquid is the deep eutectic solvent; (2) extraction of smoke powder: add 5-15wt to the deep eutectic solvent in step (1) % water, mix well, then take 1 part of deep eutectic solvent aqueous solution, add 5-10% w/v tobacco powder, microwave extraction for 10-30 minutes, filter with 0.22‑0.45μm filter membrane, and the obtained clear liquid is the electronic cigarette liquid. The purpose of the present invention is to provide a method for preparing e-cigarette liquid that has a large amount of smoke during smoking, increases the smoker's experience, saves ingredients, and makes the sensory quality of e-cigarettes closer to that of traditional cigarettes. |
