Simultaneous Determination of Sudan Dyes and Carotenoids in Red Pepper and Tomato Products by HPLC

To simultaneously detect Sudan dyes and carotenoids in red pepper and tomato products, high-performance liquid chromatography (HPLC) methods with photodiode-array detection are developed and validated. The methods include the use of end-capped and nonend-capped adsorbents with a gradient elution sys...
