Abstract

To compare the stability of pigment from Antarctic fungi Geomyces WNF-15A with cochineal pigment, different conditions of temperature,UV,Redox agents,food additives,metal ions,acid and alkaline were studied. The results demonstrated that the maximum absorption wavelength of Antarctic red pigment and cochineal pigment were 528 nm and 508 nm and the color value were 144. 3 and 120. 1. The study also showed that the Antarctic red pigment has a high resistance to UV,and very stable in pH from 6 to 10. It also has good stability to the great majority metal ions. In conclusion,because of its stability,Antarctic red pigment can replace cochineal pigment.

Key words： Antarctic red pigment; stability; cochineal pigment; metal ions; food additives; acid and alkaline
