| 摘 要： | 本文报道Fe~(2+),Fe~(3+)……Ca~(2+)等9种金属离子对桑椹红色素稳定性影响的研究。结果表明:Fe~(2+),Fe~(2+),Cu~(2+),Zn~(2+)对该色素颜色的稳定性有不利影响;Mg~(2+),Al~(3+),K~+,Na~+,Ca~(2+)等5种金属离子有增强其吸收值的作用,其中Al~(3+)增色作用最为明显,Ca~(2+)护色作用较为突出,但它们的作用都随时间延长而逐渐降低。

| Abstract: | This paper reports the nine metal ions influence upon the stability of Mulberry red pigment. It's results showed that the Fe~(2+), Fe~(3+), Cu~(2+) and Zn~(2+) are unfavourable metal ions influence upon the stability of this pigment. The other five metal ions (Mg~(2+), Al~(3+), K~+, Na~+, Ca~(2+)) can strengthen the light absorption of it,especially, the Al~(3+) is quite obiviously. The pigment is better kept by Ca~(2+) action, but, their action will decline gradually along with the time extension. |
