CHLOROPHYLL E140 is the
green pigment that is found in all plants that are capable of photosynthesis
and it has thus always been a component of the diet. The pigment
is obtained by solvent extraction from three main sources, grass,
alfalfa and nettles. It is an oil soluble pigment that provides
an olive green shade of colour.
COPPER CHLOROPHYLLIN E141 is obtained
by the coppering of chlorophyll following its alkaline hydrolysis.
The improved stability and brightness of copper chlorophyllin leads
to its much wider use than chlorophyll as a food colour.
Available in both liquid
and powder preparations, copper chlorophyllin produces a blue
green shade when dissolved in water and is frequently blended
with curcumin to provide lime green tints. Its stability to heat
and light is good but precipitation can occur if it is used in
acidified systems. For such applications this problem can usually
be avoided by using specially protected PHYTONE products. Chlorophyll
and copper chlorophyllin products are especially useful in sugar
confectionery, dairy products, sauces, pickles, jams and dry
mixes.
