摘　　要：本研究针对加热卷烟滤嘴料香挥发性强、有效释放率低的问题,利用壳聚糖和聚己内酯通过静电纺丝和加热混合包埋技术,成功制备了新型料香包埋材料.通过红外光谱、热重分析和气相色谱等测试,评估了该材料的结构、留着率、释放性能及稳定性.结果表明,该材料对薄荷醇的负载率高达59.72%,常温留着率达78.58%,抽吸时的释放率超过85%,在14 d稳定性测试中,薄荷醇留存率较晶体形态提高15%.细胞实验进一步验证了其高生物相容性和低浓度依赖性的优势.这一研究为提升加热卷烟滤嘴的香料释放效率和感官品质提供了新策略.This study addresses the issue of strong volatility and low effective release rates of flavoring materials in heated cigarette filters by employing chitosan and polycaprolactone through electrospinning and heat-mixed encapsulation techniques to successfully develop a new type of flavoring encapsulation material.The structure,retention rate,release performance,and stability of this material were evaluated using infrared spectroscopy,thermogravimetric analysis,and gas chromatography.The results demonstrated that this material achieved a high loading rate of menthol at 59.72%,a room temperature retention rate of 78.58%,and a release rate exceeding 85%during smoking.In a 14 day stability test,the retention rate of menthol was improved by 15%compared to its crystalline form.Cell experiments further confirmed its advantages of high biocompatibility and low concentration dependency.This research offers a new strategy for enhancing the flavor release efficiency and sensory quality of heated cigarette filters.
