A World Survey of Water Activity of Selected Saturated Salt Solutions used as Standards at 25°C

This paper presents and discusses the results of a world survey of water activity (aw) of selected saturated salt solutions used as standards by different researchers engaged in aw determinations for food‐related applications. Salt slurries cover the range of aw about 0.57‐0.97 at 25°C and are NaBr,...

This paper presents and discusses the results of a world survey of water activity (aw) of selected saturated salt solutions used as standards by different researchers engaged in aw determinations for food‐related applications. Salt slurries cover the range of aw about 0.57‐0.97 at 25°C and are NaBr, NaCl (NH4)2SO, KCl, BaC12. 2H2O, KNO3 and K2SO4. The results indicate that there is a good agreement on the exact value to be assigned to NaBr, NaCl, KC1 and BaC12.2H2O, and to a lesser extent, to K2SO4. However, a significant discrepancy exists between researchers on the aw value assigned to (NH4)2SO4 and KNO3. Copyright © 1984, Wiley Blackwell. All rights reserved Fil:RESNIK, S.L.
