“…There have been only a limited number of previous studies on either the release rates of AITC from CDs or on the stability of AITC in the presence of CDs. Furuta et al6 examined the release rate of AITC as well as other flavor compounds at various temperatures from β‐CD as encapsulation material and found that the rate was directly related to the surrounding water vapor concentration. Shiga et al7 discovered that the rate of release of AITC from α‐, β‐, or γ‐CDs increased markedly with increasing relative humidity, independent of the type of CD.…”

The natural antibacterial agent allyl isothiocyanate (AITC) encapsulated in either a-or b-cyclodextrin (CD) has previously been evaluated as a slow-release additive in polylactide-co-polycaprolactone (PLA-PCL) films designed for use in cheese packaging. In the research described in this article, thermogravimetric analysis (TGA) and thermogravimetric analysis in tandem with mass spectrometry (TGA-MS) were used to explore the thermal properties of CDencapsulated AITC complexes as well as those of PLA-PCL films containing these complexes. To our knowledge, this is the first reported application of the TGA-MS technique to explore the thermal stability of CD-entrapped AITC and the first study to report differences in thermal stability of AITC in a-and b-CD cavities in the solid state. Observed differences in the thermal degradation profile of films containing the CD complexes can be explained if AITC binds more strongly to b-CD than to a-CD. This hypothesis has been reinforced by gas chromatography (GC) and high performance liquid chromatography (HPLC) studies, the results of which suggest that a new covalently bound AITC-CD complex may be formed when incorporating the b-CD complex of AITC in PLA-PCL films but not when incorporating the a-CD complex of AITC. This finding means that the a-CD complex of AITC would be preferred in situations where adequate longterm controlled release of AITC from polymer films is required, as for example in the case of active packaging applications.
