Lutein (LUT) is a kind of carotenoids and is known for improving eye health. However, its poor absorbability and low stability are key issues to be improved for use as supplements. In this study, LUT-α-cyclodextrin complex (LUT-α-CD) was prepared and evaluated its solubility and stability against oxidation. As a result, solubility of LUT in FeSSIF (Fed State Simulated Intestinal Fluid) was highly improved in the case of LUT-α-CD compared with LUT oil and other complexes. Further, oxidative stability of LUT-α-CD was also improved by addition of vitamin C in comparison to Oil and Vitamin C-free-LUT-α-CD complex. |
