Water Absorption in Fluid Milk Using Fourier Transform Infrared Spectroscopy

Abstract

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. © 1991, American Dairy Science Association.
