Molecular dynamics of water and water activity in glycerol-water mixtures

Nakagawa, Hiroshi

Water activity is an indication of the microbial growth, enzymatic activity, preservation, and quality of foods. The water activity of glycerol-water mixtures can be controlled by changing its ratio. In this study, the diffusive dynamics of water were investigated at various water activities by incoherent quasi-elastic neutron scattering. It was found that water activity dependent diffusive water dynamics is correlated with the water sorption isotherm.
