EDTA对红花黄色素的稳定效应

对红花黄色素褪色及变褐因素进行了探讨,并对改善其色泽稳定性的方法进行了研究。结果表明,加入EDTA不仅可减慢红花黄色素溶液的褪色速度,还可有效抑制铁离子对其产生的影响,使之应用范围扩大,提高了使用价值。

This paper studies the discoloration and browning of carthamus yellow color and the way of increasing the pig ment's stability.The results show that EDTA can not only slow down the discoloration speed of carthamus yellow color,but also can effectively inhibit the effect of iron ion on it,which so increased pig ment's application and value.
