两亲性淀粉自组装研究进展

Research progress on self-assembly of amphiphilic starch

两亲性淀粉具有独特的结构特征,将其溶于选择性溶剂中,在疏水力的推动下会自组装形成核-壳结构的球形胶束。胶束可包合疏水性客体,对客体进行空间束缚,形成超分子包合物。两亲性淀粉自组装扩大了淀粉作为载体的应用范围。总结了两亲性淀粉自组装的原理、制备方法、影响因素,介绍了该方法应用于食品、医药、工业领域的研究进展,并提出了目前两亲性淀粉自组装研究领域存在的问题以及今后可能的研究方向。

Amphiphilic starch(AS)is dissolved in selective solvents and can self-assemble to form spherical micelles with a core-shell structure under the push of hydrophobic force due to its unique amphiphilic structural characteristics.The micelles can enclose hydrophobic guests and confine them in space to form supramolecular inclusion compounds.AS self-assembly expands the application range of starch as carrier.The principles,preparation methods and influencing factors of AS self-assembly are summarized.The research progress of this method in the fields of food,medicine and industry are introduced.The existing problems in the field of AS self-assembly and the possible research direction in the future are put forward.
