In the work shown here, sialic acids are determined in infant formulas following acid hydrolysis. Two sample preparation methods are presented: one uses ion-exchange and the other uses enzyme digestion. Each method has advantages for a specific type of sample, allowing options for sample-preparation optimization. Both methods remove many potentially interfering compounds present in a complex matrix such as infant formula.
