First claim
Opening claim text (preview).
What is claimed is: 1. A colorant composition comprising: a crystalline pigment or mixture of pigments derived from plants or algae, wherein the composition has a color intensity that is higher than raw juice, wherein the composition has decreased sugar on a dry weight basis than raw juice, and wherein the composition has a bulk density of at least 0.62 g/cm 3 . 2. The composition of claim 1 , containing less than about 5-20% sugar on a dry weight basis. 3. The composition of claim 1 , having a color intensity greater than about 40,000 color units. 4. The composition of claim 1 , wherein the pigment is a red grape anthocyanin and the composition has a color intensity of about 40,000-55,000 color units. 5. The composition of claim 1 , wherein the pigment is a purple carrot anthocyanin and the composition has a color intensity of about 90,000-125,000 color units. 6. The composition of claim 1 , further comprising a total sugar content of less than 20% of dry weight. 7.
