A more detailed pattern of the available carbohydrates in infant formulas, i.e., sugars, starch and total oligosaccharides (measured as oligosaccharide‐derived glucose) was obtained using ion‐moderated partition chromatography with fixed‐ion, resin‐based HPLC columns. Twenty‐five infant formula products were analyzed. Lactose, the main sugar in standard infant formula, was often associated with its non‐absorbed isomer, lactulose. Soy‐based formulas contained sucrose and many had substantial amounts of oligosaccharide‐derived glucose. Formulas for premature infants had less than half the lactose of standard formulas with oligosaccharide‐derived glucose supplying 35 to 57% total carbohydrate. Protein hydrolysate formulas had the highest amounts of starch.
