Natracol Chlorophyll/ Copper Chlorophyllin

Chlorophyll (E140(i)) 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 (E141(i)). The water soluble forms, Sodium Chlorophyllin (E140(ii)) and Sodium Copper Chlorophyllin (E141(ii)) are obtained by the saponification of oil soluble forms. The Copper Chlorophyllin pigment gives bright green and is very stable against light and heat, whereas standard Chlorophyllin gives olive green and has poor stability in both of these conditions.
