Chlorophylls are the most widely distributed plant pigments responsible for the characteristic green color of
fruit and vegetables (1). The major chlorophylls in foods are chlorophyll a, which has a methyl group at C-3
carbon, and chlorophyll b, which a formyl group is bonded to the same carbon atom. Chlorophylls a and b are
typically found in higher plants and occur in approximate ratio of 3:1 in fruits and vegetables. They are also
different in case of color where chlorophyll a appears blue-green and chlorophyll b possesses yellow-green
(2), as well as their thermal stability. Chlorophyll a was reported to be thermally less stable than chlorophyll
b (3, 4, 5, 6, 7).
