Abstract: In order to expand the screening range of cooling materials for traditional cigarettes, the eutectic point of xylitol and erythritol was calculated through the binary phase diagram of xylitol and erythritol. A binary eutectic sugar alcohols particles of xylitol and erythritol were prepared by melting method and applied as a cooling material in traditional cigarettes, and their heat absorption and cooling effects were evaluated. The results showed that the ratio of the amount of xylitol to erythritol at the eutectic point of binary eutectic sugar alcohol was 7.6∶2.4, which was named as X_7.6E_2.4 eutectic sugar alcohol particles, and the eutectic temperature was approximately 89 ℃. The preparation process of the eutectic sugar alcohol particles did not undergo any chemical reaction, and their morphological characteristics were similar to those of xylitol particles, with a relatively smooth surface. When applied to medium and short length cigarettes, the mainstream smoke temperature of the cigarette was reduced by 6.8 ℃ compared to blank cigarettes. Xylitol particles could effectively retain moisture from mainstream smoke. The more xylitol content was added to binary eutectic sugar alcohol particles, the less moisture was captured at the cigarette outlet. Binary eutectic sugar alcohol particles could intercept some of the tar in mainstream smoke, among which X_7.6E_2.4 eutectic sugar alcohol particle cigarettes capture the least amount of tar at the outlet, but binary eutectic sugar alcohol particles had no significant effect on the nicotine and CO content in mainstream smoke. The cigarette with added X_7.6E_2.4 eutectic sugar alcohol particles showed an improvement in the sweetness of the smoke, but the suction resistance slightly increased. In addition, the heat sensation of the smoke of cigarettes was decreased, resulting in the highest the overall sensory quality evaluation.
