| 摘 要： | 通过悬浮液法制备烯丙基异硫氰酸酯与β-环糊精微胶囊，并通过红外光谱法进行表征。结果表明，经光度法测定微胶囊中烯丙基异硫氰酸酯浓度为4．38％。被包埋后，由于β-环糊精外壳的空间阻碍，微胶囊中的烯丙基异硫氰酸酯（AITc）在85℃条件下贮藏48h保留率为17．0％，对照组3h即挥发完全；室温条件下贮藏14d微胶囊中AITc的含量几乎无变化。

| Abstract: | The microcapsules of allyl isothiocyanate-β-cyclodextrin were prepared by suspension method and characterized by Fourier transform infrared spectroscopy. By ultraviolet spectrometry, the content of aUyl isothiocyanate （AITC） in the microcapsules was determined as 4.38%. After embedding, because of the space hinder of β-cyclodextrin, the retention rate of AITC was 17.0% when stored 48 h under 85 ℃. The control sample volatilized within 3 h. The AITC content kept constant when stored at room temperature for 14 d. |
