摘　　要：为了探究南极真菌GeomycesWNF-15A分泌的红色素的稳定性，通过与胭脂虫红色素的对比，包括色价、紫外敏感性、氧化剂还原剂的影响、食品添加剂的影响、金属离子稳定性、酸碱稳定性等方面，发现南极红色素在528nm有最大吸收波长；色价为144．3；对紫外光稳定；对绝大多数金属离子稳定；pH值在6～10内稳定。测试结果表明南极红色素稳定性较好，有成为胭脂虫红色素替代品的潜力。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 majori- ty metal ions. In conclusion, because of its stability, Antarctic red pigment can replace cochineal pigment.
