Light scattering in near infrared spectroscopy is an important phenomenon when using fluid milk. Experiments were carried out to measure the absorption of a near infrared overtone band of water in condensed milk by transmission at a wavelength of 1.45 µm in order to determine water content in condensed milk. Homogenization at high pressure and baseline correction of spectra permitted a linear relation between water content in milk and the absorption measured.
Key Words: water condensed milk Fourier transform infrared spectroscopy
