Dielectric relaxation and molecular interactions study of saccharides in aqueous solutions.

Time domain reflectometry (TDR) technique has been extensively used to study dielectric relaxation and solution properties of carbohydrates. Using TDR techninque, complex permittivity spectra of monosaccharides (d-fructose and d-xylose) and disaccharides (d-maltose monohydrates) were obtained in the frequency range of 10 MHz-50 GHz at various concentrations and temperatures. The static dielectric constant (ε), dielectric constant at high frequency (ε), relaxation time (τ) and relaxation time distribution parameter (β) extracted from the complex permittivity spectra using least squares fit method.
