采用高静水压技术制备了β-环糊精-维生素C（beta-CD-Vc）包合物。压力低于300 MPa时，包裹率与压力呈正相关，压力高于300 MPa时，包裹率保持在50.0%以上。傅里叶变换红外光谱（FI-IR）和紫外-可见光谱（UV-vis）分析表明，β-环糊精-Vc包合物的特征吸收峰消失，Vc的吸收峰消失。此外，差示扫描量热法（DSC）数据显示，在β-CD-Vc包合物的DSC曲线中，仅在约138 ℃处出现一个吸热峰。这些结果表明，HHP处理有效地诱导β-CD-Vc包合物的形成。(C)2012爱思唯尔有限公司保留所有权利。
In this study, a novel high hydrostatic pressure (HHP) technique was used to prepare the beta-cyclodextrin-vitamin C (beta-CD-Vc) inclusion complex. The inclusion ratio was positively correlated with the pressure under 300 MPa and remained at above 50.0% when the pressure was more than 300 MPa. Fourier-transform infrared spectroscopy (FI-IR) and UV-visible spectroscopy (UV-vis) analysis showed that characteristic absorption bands and the absorption peak of Vc disappeared in the spectra of the beta-CD-Vc inclusion complex. Furthermore, differential scanning calorimetry (DSC) data revealed that only one endothermic peak appeared at about 138 degrees C in the DSC curve of the beta-CD-Vc inclusion complex. These results indicate that the HHP treatment effectively induces the formation of beta-CD-Vc inclusion complex. (C) 2012 Elsevier Ltd. All rights reserved.
