| 中文摘要: |
| 以茁-环糊精为壁材对绿叶挥发性物质(E)-2-己烯醛、(E)-2-己烯醇进行包合，制备了2 种绿叶挥发性物质的茁-环糊精缓释微胶囊。通过紫外吸收光谱、红外光谱对微胶囊进行了表征；利用紫外分光光度法定量测定了2种绿叶挥发性物质在微胶囊中的包合比，并测定了2 种绿叶挥发性物质的释放速率。结果表明，茁-环糊精能够与(E)-2-己烯醛、(E)-2-己烯醇形成包合物微胶囊，微胶囊中茁-环糊精与(E)-2-己烯醛和(E)-2-己烯醇的包合比分别为91.6%和90.2%；22益下，空气流速为0.1 L/min 时微胶囊中(E)-2-己烯醛和(E)-2-己烯醇的释放速度分别为4.09(依0.03)伊10-2、4.06(依0.07)伊10-2 mg/h窑g。 |
| 英文摘要: |
| Using cyclodextrin as the encapsulant to complex with two species of green leaf volatiles (GLVs) (E)-2-
hexenal and (E)-2-hexen-1-ol, and obtained the GLV--CD microcapsule respectively. The -CD microcapsule泽were
analyzed by UV and FTIR spectrum. The inclusion ratio of GLV-茁-CD microcapsules were determined by ultraviolet
spectrophotometry. The release rates of (E)-2-hexenal and (E)-2-hexen-1-ol were also detected. The results showed that
茁-cyclodextrin form complexes with (E)-2-hexenal and (E)-2-hexen-1-ol, and the inclusion ratioes of two GLV
compounds were 91.6% and 90.2%. With an airflow of 0.1 L/min, the average release rates of (E)-2-hexenal and (E)-2-
hexen-1-ol from microcapsule powder were 4.09(0.03)10-2 and 4.06(0.07)10-2 mg/hg respectively (22). |
