Abstract
A new form of green color is prepared by specially treating copper chlorophyllin to make it acid-stable and cold-water-soluble. The new composition has a unique combination of properties makes it especially suitable for use in dry mix compositions for preparing acidic beverages and foods such as gelatin desserts. The dry, water-soluble, acid-stable green coloring composition contains copper chlorophyllin, a solid fixative and a hydrophilic surfactant. The weight ratio of the copper chlorophyllin to the hydrophilic surfactant is in the range of from about 1:1 to 1:6. For beverages and gelatin dessert mixes, flavor and sufficient acid are employed to achieve a pH of less than 4 when the dry mix composition is mixed with water.
