Why test water activity

Water activity generally refers to the testing method based on the ERH method to characterize the moisture content. This characterization method can directly reflect the characteristics of adsorbed water in many industrial and agricultural production processes. And the adsorption of water largely determines surface chemical reactions, for example, it is one of the control conditions for bacterial reproduction, an intermediate control condition for many industrial synthesis and processing, and the most widely used catalyst, which determines the prerequisite for surface adsorption. Therefore, it is directly related to adhesion, agglomeration, crystallization, coating firmness, and granulation characteristics, which determine whether many reactions can proceed normally. Developed countries such as the United States have listed it as a food testing project.

It is almost possible to use activity testing to determine the storage and preservation period of perishable and wilting substances such as food, feed, fruits, and medicines.

In recent years, many countries have made food moisture activity testing a mandatory quality inspection indicator.

In the particle powder industry, water activity can more directly reflect the bonding and adhesion phenomena of particles.

It can reflect the influence of working conditions on bonding strength in the paint coating process.

The water activity also reflects the performance of microorganisms, enzymes, and catalysts very accurately and directly.

The water activity is also directly related to the deformation of paper, film, tape, and other materials.
