Water activity "x" is the mole fraction of water in the aqueous fraction. Relationship to relative humidity: The relative humidity of air in equilibrium with a sample is called the Equilibrium Relative Humidity (ERH). Estimated mold-free shelf life in days at 21° C: Water activity is an important consideration for food product design and food safety. Food designers use water activity to formulate shelf-stable food. If a product is kept below a certain water activity, then mold growth is inhibited. This results in a longer shelf life. Water activity values can also help limit moisture migration within a food product made with
