PREDICTION OF WATER ACTIVITY OF AQUEOUS SOLUTIONS IN CONNECTION WITH INTERMEDIATE MOISTURE FOODS: EXPERIMENTAL INVESTIGATION OF THE aw LOWERING BEHAVIOR OF SODIUM LACTATE AND SOME RELATED COMPOUNDS

The water activity lowering behavior of sodium lactate, lactic acid, and other related hydroxy acids as well as its sodium salts, has been experimentally determined. The results for the sodium salts were very well fitted to Bromley's (1973) model for aw in aqueous solutions of strong electrolyt...
