Light Scattering Study of Aqueous Sucrose Solutions

Abstract

Aqueous sugar solutions are good cryopreservation agents and yet some of these sugars have not been studied extensively. Here we report results of light scattering studies of aqueous sucrose solution at concentrations ranging from 10 wt% to 50 wt%. Photon correlation spectroscopy was performed on samples at temperatures from −100C to 500C . Light scattering data were obtained from angles of scattering between 18.4<deg> and 90<deg>. The autocorrelation showed two distinct relaxations that were both found to be diffusional at virtually all concentrations and temperatures. No viscoelastic behavior was observed but, based on the experience with other sugars; we suspect that this behavior would have occurred at concentrations above 50 wt%.
