A simple and reproducible HPLC-diode array detection method for the qualitative and quantitative analysis of potential and free furfural compounds (5-hydroxymethyl-2-furaldehyde, HMF; 2-furaldehyde, F; 2-furyl methyl ketone, FMC; and 5-methyl-2-furaldehyde, MF) in milk-based formulae was developed and validated. The method showed good linearity with determination coefficients over 0.999. The limits of detection and quantification were acceptable for all furfurals. The relative standard deviations (RSDs) for repeatability and reproducibility were < 4.28. Recoveries in all furfurals were between 94.5 and 98.7%. In addition, we report the evolution over shelf life of furfural compound levels in an experimental powder formula for pregnant women stored at 25 and 37 degrees C from production until 15 months.
