摘　　要：探讨了超级黑糯玉米芯色素的理化性质和稳定性。实验结果表明:超级黑糯玉米芯色素易溶于水,属于花色苷类色素;在酸性条件下,对热有很好的的耐受性,耐可见光的性能也较好,糖和抗坏血酸对色素稳定性无影响,而氧化剂H2O2及还原剂Na2SO3对色素的稳定性影响较大,金属离子中Fe3+、Cu2+离子对色素的稳定性有不良影响,而K+、Fe2+、Na+、Ca2+、Mg2+、Zn2+、Mn2+、Al3+对色素的稳定性无影响。The physicochemical properties and stability of the pigment from super black glutinous corncob were studied.The results showed that it was a type of anchocyanin and easy to solve in water,having good resistance against heat and visible light.Sugar and Vc don＇t exert negative effects on the stability of the pigment while H2O2 and Na2SO3 has obvious negative effect,some metal ions such as Fe3＋ and Cu2＋ also have negative effects.
