中文摘要：
为了优化丁香油β-环糊精聚合物（β-CDP）香精微球的制备工艺，采用了响应曲面法（RSM），以香精的包封率和香精微球产率的回归综合得分为指标，分析了丁香油和β-CDP微球的投料比、反应温度、反应时间对香精微球品质的影响，并建立相应的预测模型；利用扫描电镜、激光粒度分布仪和综合热分析仪对香精微球进行了表征。结果表明：综合得分与丁香油和β-CDP微球的投料比、反应温度、反应时间之间的线性关系显著；在丁香油1mL，β-CDP微球用量1．82g，包合温度38．7℃，包合时间1．9h时相应的包封率和香精微球产率的综合得分有最大预测值18．89，经验证最佳工艺条件下制备香精微球的包封率为93．8％，香精微球产率94．8％，综合得分为18．52；最佳工艺下制备的香精微球的颗粒圆整，粒径分布均一，热稳定性良好。
英文摘要：
In order to optimize the technology for preparing microspherical fragrance made of β-cyclodextrin polymer （β- CDP） and clove oil, response surface methodology was adopted taking regressed comprehensive score of encapsulation efficiency and yield of the mierospherical fragrance as indicator. The effects of feedstock ratio, reaction temperature and reaction time on the quality of microspherical fragrance product were examined. Meanwhile, a corresponding model for prediction was established. The mierospherical fragrance product was characterized by scan electron microscope, laser particle size analyzer and thermogravimetric analysis. Results indicated that there is good linearity for the relationship between the comprehensive score and the feedstock ratio,the reaction temperature and reaction time respectively. Based upon the prediction model, a maximum predicted score of 18. 89 can be achieved when the feed of clove oil is 1 mL,the feed of β- CDP microspheres is 1.82 g, the reaction temperature is 38.7℃ and the reaction time is 1.9 h. Actual experience verified the comprehensive score as 18.52 with encapsulation efficiency and product yield of 93.8% and 94.8% respectively.
