| 摘 要： | 采用单波长法对饮料中胭脂红和亮蓝含量进行测定,结果显示,胭脂红在0.2～80mg/L,亮蓝在0.1～20mg/L浓度范围具有良好线性关系,回收率在98%～108%。采用单波长法和双波长法相结合对饮料中酒石黄和日落黄含量进行测定,结果显示,酒石黄在0.1～70mg/L,日落黄在0.2～60mg/L浓度范围具有良好线性关系,回收率在95%～110%。两种方法对样品检测快速、准确,且操作简便。利用双波长比值光谱法对果味汽水中酒石黄、日落黄、胭脂红含量进行测定,结果显示,酒石黄在0.1～60mg/L,日落黄在0.8～90mg/L,胭脂红在0.2～80mg/L浓度范围内具有良好的线性关系,平均回收率分别为100.5%、102.4%和101.8%。

| Abstract: | The single wavelength spectrophotometer was used to determine both ponceaue and brilliant blue of beverage. The results showed a good linear relationship for ponceaue at 0.2 ~ 80mg/L and for brilliant blue at 0.1~20mg/L,the recovery was between 98% and 108%. Both single wavelength and dual wavelength spectrophotometer were used to determine tartrazine and sunset yellow in beverage simultaneously. The results showed a good linear relationship for the tartrazine at 0.1~70mg/L and sunset yellow at 0.2 ~ 60mg/L... |
