the water activity of these types of samples. This causes the sample to release water to the vapor phase and equilibrate with the chamber. If the relative humidity of the headspace is greater than the water activity of the sample, the sample will require a long period of time to reach equilibrium.

Water activity is related to water content in a non-linear relationship which is represented using as a moisture sorption isotherm curve. 3.2 ater Activity (a W. w) This is the most important parameter . of water in terms of food safety.

the water activity. Rather, a w is measured with an indirect method. Water activity is measured by equilibrating the liquid phase water in the sample with the vapor phase water in the headspace of a closed chamber and measuring the relative humidity of the headspace. Methods for water activity determinations are detailed in the Official Methods of

water activity using a laboratory test. Water activity is a better measure of available water for microbial growth than MPR. Minimizing available water (e.g., achieving a water activity of 0.80 or less) is critical for controlling the growth of pathogens. For meat and poultry jerky, biological hazards will most likely include the microbiological

Water Activity (A w) Every microorganism has a minimum, optimum, and maximum water activity for growth. Water activity is a mea-sure of the water available for microbial growth. The water activity is measured instrumentally using either an electric hygrometer or a dew point instrument. Yeasts and molds can grow at low water activity.
