摘要
我国法定可使用的合成食用色素主要有5种。即苋菜红、胭脂红、柠檬黄、日落黄和亮蓝。根据调色需要,它们常被混合配置应用.目前一般采用高效液相色谱和层析分离法分析,但尚缺少可靠的同时测定此5组分的化学计量学方法。
Mixed samples containing amaranth,new coccine,tartrazine,sunset-yellow and brilliant blue were analyzed with an on-line Kalman filtering system composed of a Varian DMS 200 UV/VIS spectrophotometer,an IBM PC/AT micro-computer and the relevant supporting software.The simultaneous determination of five individual components was successfully completed without prior separation and with a good accuracy and high speed.
