Abstract
The objective of this study was to investigate the microencapsulation of Cinnamomum osmophloeum leaf oils with β-cyclodextrin; it is expected to improve the conservation of C. osmophloeum leaf oils. Chemotypes of leaf oils were classified by gas chromatograph-mass spectrometry (GC-MS) analysis. Content of linalool in the linalool-type leaf oil was 93.30%; and trans-cinnamaldehyde content in the cinnamaldehyde-type leaf oil was 84.13%. Two type oils were microencapsulated with β-cyclodextrin. Based on the FTIR analysis, the characteristic absorption bands of constituents appeared in the FTIR spectra of leaf oil microcapsules. The volatile property of microencapsulated leaf oil was evaluated by headspace GC-MS. The emission of constituents from microcapsules reduced obviously when the environmental temperature was below 60℃. Results from two kinds of aging tests, leaf oil microcapsules with β-cyclodextrin shell were was stable under the high temperature condition, and it was beneficial to reduce the emission of C. osmophloeum leaf oils.
