Detection of counterfeit and relabeled infant formulas by high-pH anion-exchange chromatography-pulsed amperometric detection for the determination of sugar profiles.
High pH anion-exchange separation with pulsed amperometric detection (HPAE-PAD) is used to characterize various milk-based, soy-based, and protein hydrolysate infant formulas based on carbohydrate profiles. Counterfeit and relabeled formulas are compared to authentics. Figures of merit are shown for glucose, fructose, lactose, sucrose, and maltose.
