FUNCTION IN FOODS: An oil-soluble blue-green food colour; can be rendered water-dispersible by use of a suitable emulsifier
ALTERNATIVES: Other green colours, although not of time same hue (and not necessarily oil-soluble), include: Green S
E142; Copper chlorophyllin; Chlorophyll
TECHNOLOGY OF USE IN FOODS: Fully oil-soluble, so predilute or direct addition to oil-based foodstuffs. Heat stability is far superior to
that of the uncoppered form, as is stability to oxidation. Water-dispersible forms based on a suitable
emulsifier are used for aqueous-based foodstuffs.
SYNERGISTS: None known
ANTAGONISTS: Sulphur dioxide
FOOD SAFETY ISSUES: None known; however, copper chlorophyll is not considered natural since the copper addition is
performed artificially
