Abstract
Official abstract text for this publication.
A crystalline pigment or colorant composition having high color intensity and/or low sugar content, and methods and processes of preparation. The composition may comprise purified fruit and/or vegetable color juices.
First claim
Opening claim text (preview).
What is claimed is: 1. A composition, comprising: a crystalline pigment or mixture of pigments derived from plants or algae, wherein the crystalline pigment or mixture of pigments is produced via refractive window drying or freeze drying and comprises glassy, angular crystals with micropores. 2. The composition of claim 1 , wherein the crystalline pigment or mixture of pigments is a water soluble powder. 3. The composition of claim 1 , wherein crystalline pigment or mixture of pigments has a color intensity that is higher than that of a raw juice extracted from the plants or algae. 4. The composition of claim 1 , wherein the glassy, angular crystals are larger than crystals produced by spray drying. 5. A colorant, comprising: a crystalline pigment or mixture of pigments derived from a photosynthetic organism and produced via refractive window drying or freeze drying, wherein the crystalline pigment or mixture of pigments comprises a powder with glassy, angular crystals. 6. The colorant of claim 5 , wherein the photosynthetic organism is a plant. 7. The colorant of claim 5 , wherein the photosynthetic organism is algae. 8. The colorant of claim 5 , wherein the glassy, angular crystals comprise micropores. 9. The colorant of claim 5 , wherein the glassy, angular crystals are larger than crystals produced by spray drying. 10. The colorant of claim 5 , wherein the powder comprises a particle density that is greater than a particle density of a powder produced by spray drying.
