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.
