紫荆花色素-β-环糊精包合物制备及稳定性研究

Study on the Preparation of Red Pigment from Cercis Chinensis Bge-β-Cyclodextrin Inclusion Compound and its Stability

阐述了紫荆花红色素与β-环糊精包合物的制备及其稳定性的研究。采用饱和水溶液搅拌法制备包合物。通过红外谱图对照分析对其进行鉴定,并将包合物与色素在光照、不同p H、不同温度下比较各自的色泽损失率。结果表明:色素包合物在光照、不同p H、不同温度条件下的稳定性与包合物相比均有一定程度的提高。

This topic has elaborated the preparation of inclusion compound of red pigment from Cercis Chinensis Bge withβ-cyclodextrin and its stability. The inclusion compound was prepared by saturated aqueous solution through stirring. The red pigment and the inclusion compound were identified by infrared spectra. The stability of inclusion compound and red pigment was measured under different light, pH, temperature. The result indicated that the stability of red pigment from Cercis Chinensis Bge was improved after inclusion.
