Chlorophyll is an oil soluble pigment obtained from Lucerne, Nettle, Spinach and Grass, providing an olive green color. The addition of Copper results in Copper Chlorophyllin. The water soluble form, Sodium Copper Chlorophyllin, is obtained by the saponification of oil soluble forms. The Copper Chlorophyllin pigment gives bright green and is very stable against light and heat.
Typical applications include confectionery, desserts, beverages, dairy products, ice cream, fruit preparation, bakery products, soups, sauces, snack food, seasonings, and convenience food.
