A delivery system for bioactive conjugated linoleic acid (CLA) through a self-assembled amylose-CLA complex was investigated in comparison with a beta-cyclodextrin (BCD)-CLA complex. Successful complexation between CLA and amylose or BCD was confirmed by differential scanning calorimetry, X-ray diffraction, and Fourier transform infrared spectral analysis. The yield and complexing percentages were 71.9 and 1.4% for the amylose-CLA complex and 42.3 and 7.7% for the BCD-CLA complex, respectively. However, the amylose-CLA complex showed a better antioxidative protection effect on CLA than BCD-CLA complex, supporting a strong complexing interaction between CLA and amylose shown by thermogravimetric analysis. Compared to 15.9% of CLA released from the BCD-CLA complex under simulated small intestine conditions, 95.6% of CLA was released from the amylose-CLA complex. These results indicate that an amylose-lipid complex self-assembled in the natural way of food component interaction can be used to protect and deliver functional lipids or other bioactive components into the targeted small intestine for absorption.
