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,Loosbroek曾用卡尔曼滤波光度法鉴
China’s statutory use of synthetic food coloring there are five main. Namely amaranth, carmine, lemon yellow, sunset yellow and bright blue. They are usually mixed and applied according to the needs of grading. Currently, high-performance liquid chromatography and chromatographic separation are generally used, but there is no reliable stoichiometric method for simultaneous determination of the five components. Loosbroek used Kalman filter to measure the luminosity Faqian
