DESIGN OF CURCUMIN-PEPTIDE COMPLEX HAVING IMPROVED SOLUBILITY AND FUNCTION COMPARED WITH CURCUMIN AND METHOD FOR PREPARING CURCUMIN-PEPTIDE COMPLEX

The present invention relates to a curcumin-peptide complex having improved solubility in water compared with curcumin; to a method for improving solubility of curcumin in water; to a method for preparing the complex; and to a cosmetic composition and a functional health food which contain the complex. The present invention provides a curcumin-peptide complex in which a peptide material validated to have biocompatibility and safety is linked to curcumin as a natural resource having a very excellent functional effect via a linker compound, and the curcumin-peptide complex is completely dissolved in water. The present invention provides a method for improving solubility of curcumin in water, thereby contributing to an increase in availability of curcumin as medicines, cosmetics, and food.
