Molecular Basis of Water Activity in Glycerol–Water Mixtures [PDF]

Frontiers in Chemistry, 2019
Water activity (Aw) is a reliable indication of the microbial growth, enzymatic activity, preservation, and quality of foods. However, a molecular basis of Aw is still under debate in multiple related disciplines.

Water activity [PDF]

Journal of Spectroscopy, 2012
Microorganisms require water for their metabolic activities. Only a fraction of water in foodstuffs, the so-called “free water”, is available for this purpose. The amounts of “free” water previously estimated by two different methods [J. Phys. Chem. A 114 (2010), 11933–11942; J. Phys. Chem. A 155 (2011),
