Coloring 9+ books water activity is measure of If water activity decreases micro-organisms with the ability to grow will also decrease. Water activity is the measurement of the equilibrium relative humidity ERH of a material that is the humidity that a hygroscopic material generates when it comes into balance with the air surrounding it in a sealed headspace. This value indicates how tightly water is bound structurally or chemically within a substance. See also coloringpages and water activity is measure of This unattached water is referred to as Free water while the unavailable water is called Bound.
It is therefore important with regard to food safety. As temperature increases aw typically increases except in some.

The correct definition Water activity a measure for the energy status of the water in a system specifies the relationship between the water vapor pressure of a product and the saturation pressure of pure water at the same temperature.
There are several factors that control water activity in a system. If there is too much water in a product there is a risk of microbial growth and water migration. This is the most important parameter of water in terms of food safety. The measurement of water activity or equilibrium relative humidity ERH is a key parameter in the quality control of moisture sensitive products or materials. Colligative effects of dissolved species eg salt or sugar interact with water through dipole-dipole ionic and hydrogen bonds. The water activity aw of a food is a measure of availability of water for the metabolic activity and growth of microorganisms.
