| 摘 要： | 用不同溶剂处理迎春花,只有蒸馏水处理迎春花可以较容易地得到色素,说明迎春花含有水溶性色素较多。经测定,在可见光479nm处有一最大吸收峰。实验表明,碱性条件有利于其显色。金属离子对色素有增色作用,尤其是Fe3+、Pb2+对色素影响相当明显。但食品添加剂对增色不明显。色素抗强氧化剂能力稍差,但对一般的氧化剂和还原剂的耐受性能较好。从温度影响实验可知,迎春花中可能有3类色素,低分子质量色素、中等分子质量色素及在90℃下也不易分解的耐温色素。

| Abstract: | The pigment of Jasminum nudirlorum Lindl. is easy to be extracted by water,which has a maximum absorption at 479 nm. The experiments show that the color of the pigment turned dark under the condition of basicity or metal ion, especially in the solution with Fe 3+ or Pb 2+. However, the color doesn't grow under the food additive presence. The pigment is deficient to the powerful oxidant in the resistance, but perfect to the general one. In the experiment of different temperature,the pigment of Jasminum nudirlorum Lindl. might be devided into three kinds. |
