粘质沙雷氏菌产红色素的稳定性研究
Investigate the stability of serratia rubidaea red pigments
本文对粘质沙雷氏菌所产红色素进行稳定性的考察。研究光照、温度、氧化剂、还原剂、pH、金属离子等对粘质沙雷氏菌红色素稳定性的影响。结果表明：温度对其稳定性影响不大，热稳定性好。 酸性环境中能保持较长的时间，碱性条件下则损失较大。紫外光对红色素有一定的影响，溶液在紫外灯下放置6h，色素的残存率为初始的33%。Na+对红色素的稳定性影响不大，Ca2+和Mg2+有使其增色的作用，Cu2+和K+对红色素有一定的破坏作用。红色素对双氧水比较稳定，还原剂有较好的保护作用。

The stablity of red pigments was studied on illumination, temperature, metal ion, pH, oxidant and reducing agent. The results showed that the red pigments solution was stable to temperture, pH 5-10, H2O2 and Na2SO3, but sensitive to ultraviolet radiation. Moreover, its red pigment was protected by Ca2+ and Mg2+, and was faded by K+ .Red pigment for hydrogen peroxide is stable. Red pigment has better protection effect to reducing agent
