[0062] Sensory evaluation of the following e-cigarette aerosol liquid additives in experimental groups 1 to 3:

[0063] Sensory evaluation items and score settings: stimulation, bitterness, sourness, and fragrance; each item is scored from 1 to 5 points, with 1 point as the minimum scoring unit. For stimulation, the stronger the stimulation, the higher the score; for bitterness, the stronger the bitterness, the lower the score; for sourness, the stronger the sourness, the higher the score; for fragrance, the longer the fragrance, the higher the score. The higher the total score, the better the user's sensory experience.

[0064] Evaluation procedure: 10 smokers with a smoking experience of 5 to 10 years were selected as smokers. All smokers had no adverse oral health conditions. Each smoker was provided with sample groups 1 to 4 for smoking evaluation. After smoking each sample, a corresponding score was made on the score sheet. There should be at least 30 minutes between the smoking evaluations of two samples, and the mouth should be rinsed with drinking water at least 5 times.

[0065] Comparison of scaled score items

[0066]

[0067] According to the sensory evaluation results, the sourness and aroma scores of experimental group 1 are significantly higher than those of other experimental groups, indicating that the additives prepared by adding the ingredients described above to a suitable ratio have good sourness and aroma, low bitterness in the mouth, and low irritation when used in electronic cigarettes.
