Method to solubilize curcuminoids in water

A method of solubilising curcumin/curcuminoid mixtures whereby aqueous solubility of curcumin/curcuminoid mixtures is enhanced to more than 10%-15% w/v in water using polyvinyl pyrrolidone (PVP) and dioctyl sulfosuccinate (AOT) or Docusate sodium, said method comprising steps of

• a) Stirring continuously at room temperature a mixture of polyvinyl pyrrolidone (PVP) and dioctyl sulfosuccinate (AOT) taken in ethanol till the solution of said mixture becomes clear;
• b) Adding curcuminoids at room temperature to the solution of step a followed by continuous stirring for 15 hours to further get a clear solution;
• c) Evaporating the ethanol in solution of step b using Rota evaporator and further adding distilled water to get a clear mixture;
• d) Removing any insoluble material from the clear mixture of step c by filtration;
• and
• e) Spray drying the resulting mixture of step d at 140-150° C. using a spray dryer to get the final product of solubilised curcuminoids wherein the assay of curcuminoids in the final product by HPLC indicates not less than 10% why of curcuminoids.
