螺旋藻油与β-环糊精包合物的制备

Preparation of spirulina oil inclusion compound withβ-cyclodextrin

对螺旋藻油与β-环糊精包合物的制备工艺进行了研究,优化了包合条件,最佳包合条件为:β-环糊精与螺旋藻油的比例为2.5∶1,包合温度为50℃,包合时间为5h,包合率为76.1%～77.6%。仪器分析结果表明,螺旋藻油与β-环糊精的包合为物理包合,包合前后螺旋藻油的成分组成及相对百分含量未发生改变,包合后螺旋藻油的水溶性明显改善,可用于水溶性环境,大大拓宽了其应用范围,包合后螺旋藻油稳定性也得到显著提高,改善了其加工条件。

The preparation process of spirulina oil andβ-CD Inclusion Compound is studied in this paper.The optimum preparation condition was:mole ratio of spirulina oil toβ-cyclodextrin about1:2.5,stirring for 5hours at the optimum temperature of 50℃.The chemical analysis results indicated that the characteristics of spirulina oil before and after being included were not chang ed,spirulina oil's stability and solubility in water were remarkably increased by inclusion withβ-cyclodextrin.This widens spirulina oil's application scope and betters manufacture condition.This method is an avail way to explore spirulina oil.
