There is a certain relationship between the moisture content in food and its perishability. A single moisture content is not a reliable indicator of perishability. Water activity has a good correlation with the growth of microorganisms and the speed of many degradation reactions. It can more reliably predict the stability, safety, and other properties of food than moisture content, becoming a parameter that can indicate product stability and microbial safety Many countries have designated food moisture activity testing as a mandatory quality inspection indicator.

The water activity value refers to the state in which water exists in food, that is, the degree of binding or dissociation between water and food. The water activity value has a significant impact on the color, aroma, taste, tissue structure, and stability of food. The life activities of various microorganisms and various chemical and biochemical changes require certain activity values, so activity values are of great significance for food preservation
