摘要: 研究了油桃皮红色素的提取条件和稳定性,结果表明,用料液比1:30(g:ml)、pH1的50%乙醇作提取剂、在50℃恒温浸提40min,提取效率较好。油桃皮红色素属花色素苷类色素,水溶性好,对光、热(80℃以内)的耐受性强。pH值对色素影响明显。金属离子Na+、Ca2+、A13+、Cu2+、Zn2+对色素色泽无影响,而Fe3+、Pb2+有不良影响。色素的抗氧化能力较差而耐还原性能较好。蔗糖、葡葡糖和盐等添加剂对色素无影响。

Abstract: Properties and extractions of the red pigment in the peels of Prunus persica Var.nectarina(Ait)Maxim wereinvestigated. Results showed that good yield of pigment can be obtained by 50% C2H5OH solution of pH1 at 50℃ for 40min with the solid-liquid ratio 1:30 (g:ml). The Prunus persica Var.nectarina(Ait)Maxim red pigment is classified to anthocyanins, soluble in water, for which pH shows significant effect on the hues of pigment. The pigment has good light and heat resistance under 80℃. Metallic ions Na+, Ca2+, Zn2+, A13+ or Cu2+ have no effect on the hues of pigment, but Fe3+ or Pb2+ have severe disadvantageous effect. This kind of pigment has better enduring capability against reducing agent, but it has less resisting capability against oxidizing agent. Addition of glucose or sucrose shows no effect on the pigment.
