| Abstract: | The effects of light,temperature,pH value,oxidizing agent,reluctant,Vc,preservative,sugar and metal ions on the stability of the natural red pigments from ascomycetes SD-9701 were studied.Experimental results proved that the pigment had strong resistance against light and heat.The stability of the pigment was better under the alkaline condition.Its resistance against oxidizer and reluctant was poor.Effects of Vc,sugar and preservative on the stability of the pigment did not exert negative.But Fe3 ,Cu2 ,Sn2 and Pb2 ions had bad effects on the stability.And Fe2 ion had weak effects.Other metal ions,such as Na ,Mg2 ,K ,Ca2 ,Zn2 and Al3 ions had no negative effects on the stability of pigment. |
