Application of photoacoustic spectroscopy (PAS) to the analysis of milk or dairy products is reported. We have studied the kinetic aspects of the Maillard browning reactions in milk powder tablets. The reaction rate has been assessed by using the spectral ratio I335/I280 (i.e., the PA intensity of the Maillard reaction products to that of proteins). The molar energy and enthalpy of activation were found to be 115 and 113 kJ mol-1 at 298 K, respectively. We discuss the relevance of the application of photoacoustic methodology in dairy research and the milk industry.
