Introduction to Chapter
The chlorophylls are a group of naturally occurring pigments present in all photosynthetic plants, including algae and some bacteria. They are in greater abundance than any other organic pigment produced in nature. Hendry (1) estimated annual production at about 1,100,000,000 tons, as compared with carotenoids at 100,000,000 tons, with about 75% being produced in aquatic, primarily marine, environments. Obviously, as a source of raw material for food colorants, chlorophylls present no problem with supply.
