Claims24
A method for preparing a stable dispersion of microparticulated water insoluble bioactive polyphenol comprising the steps of:
- a. dissolving at least one water insoluble bioactive polyphenol in an alkaline solution at a temperature of less than 30° C., wherein the alkaline solution has a pH of 9 to 12, to form an alkaline bioactive polyphenol solution;
- b. forming an aqueous solution containing a dispersion stabilizer, wherein the aqueous solution has a pH of 3 to 5 and a temperature below 50° C.;
- and
- c. introducing the alkaline bioactive polyphenol solution into the stabilizer aqueous solution containing the dispersion stabilizer while maintaining the aqueous dispersion at the pH of 3 to 5 and the temperature below 50° C., thereby forming a dispersion of water insoluble bioactive polyphenol particles in the aqueous solution, wherein the particles are microparticulated;
- wherein the dispersion stabilizer is present in an amount sufficient to stabilize the dispersion of water insoluble bioactive polyphenol particles.
A method for dispersing polyphenol particles in a beverage comprising a) dissolving at least one water-insoluble polyphenol in an alkaline solution at a temperature below 30° C.;
- and b) adding the alkaline solution to an aqueous beverage composition containing a dispersion stabilizer having a pH of 3 to 5 and a temperature of less than 50° C. thereby forming a microparticulated polyphenol dispersion;
- wherein the dispersion stabilizer is present in an amount sufficient to stabilize the dispersion of microparticulated polyphenol in the beverage.
A composition for a comestible comprising dispersed microparticulated polyphenol and at least one dispersion stabilizer in an aqueous solution, wherein about 90% of the polyphenol has a particle size below about 50 microns and the at least one dispersion stabilizer is present in an amount sufficient to stabilize the dispersion of microparticulated polyphenol in the aqueous solution.
