Abstract

Edible colorant compositions containing a monoacylated anthocyanin of Compound I and methods of use are provided. The colorant compositions include at least the monoacylated anthocyanin colorant of Compound I extracted from red cabbage and a metal ion, and have a pH from about 6.0 to about 8.0. The colorant compositions can be derived from a non-artificial product and provide a stable, blue colorant that can be used in food products. Specifically, the monoacylated anthocyanin colorant provides color characteristics similar to those provided by the artificial blue colorant, FD&C Blue No. 1.

Claims

exact text as granted — not AI-modified
What is claimed is: 
     
         1 . An edible colorant composition comprising:
 a) a monoacylated anthocyanin compound having the structure:   
       
         
           
           
               
               
           
         
       
       and
 b) a metal ion, 
 wherein the edible colorant composition is a solution having a pH of from about 6.0 to about 8.0. 
 
     
     
         2 . The edible colorant composition of  claim 1 , wherein the edible colorant composition is dried to produce a dry colorant composition. 
     
     
         3 . The edible colorant composition of  claim 1 , wherein the edible colorant composition is blue. 
     
     
         4 . The edible colorant composition of  claim 3 , wherein the edible colorant composition has a ΔE value of less than about 17 when compared to an aqueous solution of about 50 ppm to about 100 ppm FD&C Blue No. 1. 
     
     
         5 . The edible colorant composition of  claim 4 , wherein the ΔE value is from about 8 to about 10. 
     
     
         6 . The edible colorant composition of  claim 1 , wherein the edible colorant composition is green. 
     
     
         7 . The edible colorant composition of  claim 6 , wherein the edible colorant composition further comprises a non-artificial yellow colorant selected from the group consisting of safflower, turmeric, beta carotene, and  Gardenia  yellow. 
     
     
         8 . The edible colorant composition of  claim 1 , wherein the edible colorant composition comprises from about 0.5% to about 30% (weight/weight (w/w)) of Compound I. 
     
     
         9 . The edible colorant composition of  claim 1 , wherein the edible colorant composition comprises from about 0.5% to about 10% (w/w) of Compound I. 
     
     
         10 . The edible colorant composition of  claim 1 , wherein the edible colorant composition comprises from about 10% to about 30% (w/w) of Compound I. 
     
     
         11 . The edible colorant composition of  claim 1 , wherein Compound I is present in an amount greater than about 10% of an anthocyanin chromophore content in the edible colorant composition. 
     
     
         12 . The edible colorant composition of  claim 1 , wherein the edible colorant composition comprises from about 0.3 to about 1.0 molar equivalents of the metal ion to the monoacylated anthocyanin compound. 
     
     
         13 . The edible colorant composition of  claim 12 , wherein the metal ion is selected from the group consisting of aluminum (Al 3+ ), ferric (Fe 2+ ) or ferrous (Fe 2+ ) ions. 
     
     
         14 . An edible product comprising the edible colorant composition of  claim 1 . 
     
     
         15 . The edible product of  claim 14 , wherein the edible product is a confectionery product. 
     
     
         16 . The edible product of  claim 15 , wherein the edible colorant composition is present in a coating applied to a surface of the confectionery product. 
     
     
         17 . The edible product of  claim 15 , wherein the confectionery product is a confectionery center with a soft-panned or hard-panned sugar-based coating. 
     
     
         18 . The edible product of  claim 15 , wherein the confectionery product is a confectionery center with a soft-panned or hard-panned polyol coating. 
     
     
         19 . The edible product of  claim 14 , where the edible product comprises from about 0.0001 to about 10% (w/w) of Compound I. 
     
     
         20 . The edible product of  claim 14 , where the edible product comprises from about 0.0005 to about 1% (w/w) of Compound I. 
     
     
         21 . The edible product of  claim 14 , where the edible product comprises from about 0.001 to about 0.5% (w/w) of Compound I.
