| 摘 要： | 胭脂红、苋菜红、日落黄这三种食用色素的吸收光谱重叠严重。本文研究用主成分回归光度法解析普峰重叠体系，并对由这三种色素合成的混合样品进行了三组分的同时测定，结果令人满意，误差ASR％＜3．0％，回收率在97％～103％范围内。该法简便、快速、准确、无需预分离、可广泛地用于混合色素多组分的同时测定。

| Abstract: | In this paper,the principal component regression method was applied to resolve the overlappingspectra for simultaneouts determination of ternary mixtures of carmine,amaranth and sunset yellow. The results were satisfatory with ASR%<3. 0%and recoveries between 97 % -103 %. The proposed method wassimple,accurate and promising way without praparative resolution for multicomponents analysis in food pigments Mixtures. |
