Abstract:
The water activity of aqueous lactose solutions up to about 17% (w/w) (saturation at 25°C) has been determined from measured freezing points. As expected, results agree well with Raoult's law and do not substantiate some literature results which attributed considerably lower water activity values to lactose solutions.
