摘要
以猪血为实验材料,制备亚硝基血红蛋白色素,并确定其最佳合成参数。从光、热、pH值、氧化介质、还原介质、金属离子、防腐剂等方面对色素的稳定性进行了研究。结果表明:该色素耐光性较弱;但具有一定的耐热性;抗H2O2的能力较差,NaHSO3对它起护色作用;防腐剂苯甲酸钠及大多数金属离子对色素稳定性无不良影响,但Fe3+、Fe2+、Zn2+、Pb2+、Sn2+对色素具有不利的影响。
Porcine blood were used as experimental materials to synthesize HbNO, orthogonal experiment for the optimum parameter of synthesize of HbNO was made. The effects of light, heat, pH value, oxide, reductor, preservative and metal ions were investigated on the stability. The results indicated that this pigment has a poor capability against light. The pigment exhibited a resistance to heat treatment to certain extent, the pigment has a poor capability against H2O2, but the color of the pigment was improved by the addition of NaHSO3. sodium benzoate and most of metal ions has no negative effects on the stability of the pigment, but Fe^3＋, Fe^2＋, Zn^2＋, Pb^2＋, Sn^2＋ accelerated the pigment degradation.
