Mixed Saturated Salt Solutions as Standards for Water Activity Measurement in the Microbiological Growth Range

Present work explores the feasibility of using mixed saturated salt solutions to provide additional solutions of known water activity (aw). The mixed saturated salt solutions studied were: K2SO4‐KNO3, K2SO4‐MgSO4, KCl‐KNO3, NaCl‐KCl and NaCl‐NaNO3. The aw of the ternary saturated salt mixtures was p...
