Abstract: 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.

Key words: allyl isothiocyanate(AITC), cyclodextrin (CD), inclusion, controlled release
