This study was carried out to observed β-cyclodextrin (β-CD) inclusion complexes containing -cinnamaldehyde (CIN) by using DPPH, ABTS and FRAP assay. Antioxidative ability was compared between pure CIN and β-CD-CIN inclusion complexes and particle size, encapsulation efficiency, and temperature-dependent release of inclusion complexes were investigated. High concentration of β-CD (1.8%) as well as guest oil 1:3 molar ratio (β-CD:CIN) influenced on particle size bigger during self-assembly process. And particle sizes were increased as storage period. In the antioxidant capacity results, pure β-CD (1.8%) was antioxidative without CIN especially at FRAP assay. Antioxidant activity dramatically increased after 1:1 molar ratio (1.8% β-CD:CIN), especially at DPPH assay and ABTS assay. In this study, β-CD complexation enhanced CIN solubility and affected increase the antioxidant activity of the CIN. Moreover, we need to consider that molar ratio of between β-CD concentration and CIN is effective manufacturing condition to improve antioxidant activity of β-CD-CIN inclusion complexes.
本研究旨在通过DPPH、ABTS和FRAP测定法观察含肉桂醛（CIN）的β-环糊精（β-CD）包合物。比较了纯CIN与β-CD-CIN包合物的抗氧化能力，并研究了包合物的粒径、包封率和温度依赖性释放。高浓度的β-CD（1.8%）以及客体油1:3的摩尔比（β-CD:CIN）在自组装过程中影响粒径变大。并且粒径随着储存时间增加。在抗氧化能力结果中，纯β-CD（1.8%）在无CIN时具有抗氧化性，尤其是在FRAP测定中。在1:1摩尔比（1.8%β-CD:CIN）后抗氧化活性显著增加，尤其是在DPPH测定和ABTS测定中。在本研究中，β-CD络合提高了CIN的溶解度，并影响了CIN抗氧化活性的增加。此外，我们需要考虑β-CD浓度与CIN之间的摩尔比是提高β-CD-CIN包合物抗氧化活性的有效制造条件。
