Proposed Theoretical Water Activity Values at Various Temperatures for Selected Solutions to be Used as Reference Sources in the Range of Microbial Growth

Abstract

this paper compiles recent data on the theoretical prediction of the water activity (aw) of selected saturated salt solutions, unsaturated NaCl and LiCl solutions, and H2SO4 solutions. These results are presented in tabular form in such a way that they can be safely used as reference sources for aw determinations in the range of microbial growth (i.e. about 0.57-0.97) and at different temperatures.
