【摘要】 对小蜡色素的理化性质和稳定性进行研究。结果表明:小蜡色素易溶于水,属于花色苷类色素;在酸性条件下,对热有一定的耐受性。耐可见光和紫外光的性能也较好,抗坏血酸和防腐剂对色素稳定性无影响,而氧化剂H2O2对色素的稳定性有不良影响,还原剂Na2SO3对色素的影响比较大,金属离子中Fe3+、Cu2+和Sn2+离子对色素的稳定性有不良影响,而Na+、K+、Mg2+、Fe2+、Al3+、Pb2+对色素的稳定性无影响。更多还原

【Abstract】 The experiment systematically studied the physical, chemical properties and stability of the pigment from Ligustrum sinense Lour.. The results showed that it was a type of anchocyanin and easy to solve in water, having resistance against heat in acid condition and good resistance against visible light and ultraviolet light. Vitamin C and preservative don’t exert negative effects on the stability of the pigment while H2O2 has negative effects and Na2SO3 has obvious effects, some metal ions such as Fe3+, Cu2+ and Sn2+ also have negative effects.更多还原
