摘要：α-松油醇是多种植物挥发油的主要成分之一，具有生物学活性。为解决α-松油醇易挥发的问题，该研究采用饱和水溶液法制备α-松油醇/β-环糊精包合物。通过正交试验确定最佳包合工艺为芯壁比1.00∶1.00（n/n）、温度30℃、β-环糊精浓度6%、包合时间40min，在此条件下，包合率达（82.06±0.37）%，包合产率为（90.66±0.96）%，综合评分为（85.50±0.17）分。通过表征显示包合物呈菱形，粒径为（26.17±0.55）μm。α-松油醇的红外光谱吸收峰在包合物中消失，包合物的X-射线衍射特征峰与β-环糊精有区别，证明α-松油醇被包埋后形成了独特晶型特征的包合物。热重分析证明包合物能够降低质量损失，提高热稳定性。该试验制备的α-松油醇/β-环糊精包合物具备良好的缓释性能。研究结果可为高挥发型天然提取物在食品保鲜包装材料的应用提供依据。

Abstract：α-terpineol, one of the major components of volatile oils from various plants, possesses biological activity. To overcome the volatility issue of α- terpineol, this study employed the saturated aqueous solution method to produce α-terpineol/β-cyclodextrin clathrate compounds. Through orthogonal experiments, the optimal process conditions were determined as a core-to-wall ratio of 1.00:1.00 （n/n）, temperature of 30 ℃, β-cyclodextrin （β-CD） concentration of 6%, and clathrate time of 40 min. Under such conditions, clathrate rate reached （82.06±0.37）%, clathrate production rate was （90.66±0.96）% and comprehensive score was （85.50±0.17）.Characterization revealed that the clathrate compounds exhibited a rhombic shape with a particle size of（26.17±0.55）μm. The Fourier transform infrared spectroscopy absorption peaks of α-terpineol disappeared in the clathrate compounds, and the X-ray diffraction characteristic peaks of the clathrate compounds differed from those of β-CD, indicating that α-terpineol formed clathrate compounds of unique crystal structure after embedment. Thermogravimetric analysis demonstrated that the clathrate compounds could reduce the mass loss rate and improve thermal stability. This experiment successfully produced α-terpineol/β-CD clathrate compounds, which exhibited good sustained-release properties. The results can provide a theoretical basis for the application of high volatile natural extracts in food preservation packaging materials.
