Turmeric pigment composition and method for preparing same

Abstract

The present invention relates to a turmeric pigment composition. More specifically, the present invention provides a turmeric pigment composition in which aggregation and sedimentation of a turmeric pigment over time is effectively prevented even when a concentrated amount of turmeric pigment is incorporated in a solvent; the turmeric pigment composition also ensures a desirable color-developing property, and is capable of stably adding a deep color with a bright tone, which was never accomplished by a hitherto-known colorant.

1 . Particles comprising gum ghatti and a turmeric pigment, said particles having an average particle diameter of 1 μm or below. 
     
     
         2 . The particles according to  claim 1 ,
 wherein the turmeric pigment is coated with gum ghatti.   
     
     
         3 . The particles according to  claim 1 ,
 wherein the particles are obtained by pulverizing a turmeric pigment in a hydrous solution of gum ghatti until an average particle diameter of thus obtained particles falls to 1 μm or below.   
     
     
         4 . The particles according to  claim 2 ,
 wherein the particles are obtained by pulverizing a turmeric pigment in a hydrous solution of gum ghatti until an average particle diameter of thus obtained particles falls to 1 μm or below.   
     
     
         5 . The particles according to  claim 3 ,
 wherein the content of gum ghatti in the solution is 1 to 300 parts by mass relative to 100 parts by mass of the turmeric pigment.   
     
     
         6 . The particles according to  claim 4 ,
 wherein the content of gum ghatti in the solution is 1 to 300 parts by mass relative to 100 parts by mass of the turmeric pigment.   
     
     
         7 . A composition comprising gum ghatti and a turmeric pigment having an average particle diameter of 1 μm or below. 
     
     
         8 . The composition according to  claim 7 ,
 wherein the turmeric pigment is dispersed in a hydrous solution of gum ghatti, and   wherein the composition is obtainable by pulverizing a turmeric pigment in a hydrous solution of gum ghatti until an average particle diameter of the turmeric pigment falls to 1 μm or below.   
     
     
         9 . The composition according to  claim 8 ,
 wherein the composition has a powdered, granular or tablet form, and   wherein the composition is obtainable by subjecting the composition to dry powderization.   
     
     
         10 . The composition according to  claim 7 ,
 wherein the content of gum ghatti is 1 to 300 parts by mass relative to 100 parts by mass of the turmeric pigment.   
     
     
         11 . The composition according to  claim 8 ,
 wherein the content of gum ghatti is 1 to 300 parts by mass relative to 100 parts by mass of the turmeric pigment.   
     
     
         12 . The composition according to  claim 9 ,
 wherein the content of gum ghatti is 1 to 300 parts by mass relative to 100 parts by mass of the turmeric pigment.
