摘要
本论文利用β-环糊精对异硫氰酸烯丙酯进行分子包埋,将液态油转变为固体的包合物粉末,同时对其释放特性进行研究。结果表明,异硫氰酸烯丙酯可以和β-环糊精形成包合物,包合物中异硫氰酸烯丙酯的释放速度与环境的相对湿度密切相关,释放过程可以用Avrami方程进行较好的拟和。环糊精的包埋释放反应是一个动态的可逆过程,在密闭体系中存在一个异硫氰酸烯丙酯的顶空平衡浓度。
In this paper allyl isothiocyanate（AITC） was included by β-cyclodextrin to form a solid powder and the controlled release property of AITC from the inclusion complexes was studied. The results showed that the release rate of AITC from the β-CD-AITC complex is correlated with environmential relative humidity（RH） and the release time-courses of the complex fit well to the Avrami equation. The release reaction of CD is a dynamic equilibrium process and there is AITC equilibrium concentration in the headspace above CD-AITC complex in a sealed system.
