Summary The objective of this study was to develop and validate a rapid and efficient method for the determination of iron in commercial infant cereals using energy‐dispersive X‐ray fluorescence (EDXRF) technique. Two EDXRF devices were tested: Spectro Xepos and PANalytical Minipal 2.20 samples were used for calibration of the XRF apparatus. The technique was validated using a second set of twenty other samples and comparing results of the reference method (inductively coupled plasma‐atomic emission spectroscopy, ICP‐AES) and those of the EDXRF. No significant bias was found between the two methods. Three pellets per sample are prepared under 10 tonnes of pressure and analysed. The total time of analysis for iron is less than 20 min and this technique appears to be adequate for process control during infant cereals production.
