Product Name Chlorophylls
Synonyms CI Natural Green 3, Magnesium Chlorophyll , Magnesium Phaeophytin
Definition Chlorophylls are obtained by solvent extraction of natural strains of edible plant material , grass, lucerne and nettle. During the subsequent removal  of solvent, the naturally present co-ordinated magnesium may be wholly or partly removed from the chlorophylls to give the corresponding phaeophytins. The principal colouring matters are the phaeophytins and magnesium chlorophylls. The extracted product, from which the solvent has been removed, contains other pigments such as carotenoids as well as oils, fats and waxes derived from the source material. Only the  following solvents may be used for the extraction: acetone, methyl ethyl ketone, dichloromethane, carbon dioxide, methanol, ethanol, propan-2-ol and hexane.
