Water Activity and the measurement of free water in food

Water activity is a measure of water in a material that is available to react with or attach itself to another material. This unattached water is referred to as “Free" water, while the unavailable water is called “Bound”. Water Content is not Water activity but is the total amount of water in a product -- both Bound Water and Free Water.
