The water activity meter is mainly used to reflect the effective water, product stability, and microbial reproductive ability that microorganisms can utilize or participate in chemical reactions under the equilibrium state of food. By measuring the water activity of food and selecting appropriate packaging and storage methods, the use of preservatives can be reduced, and the shelf life of food, grains, fruits and vegetables can be determined.
Water activity (water activity) is a critical factor that directly affects the shelf life of food. Temperature, pH, and other factors can affect the possible growth and growth rate of organisms in food. However, water activity is usually the most influential factor. The price of a water activity meter varies depending on the model, brand, functionality, and performance level. The water activity meter has the advantages of non-destructive testing, fast and accurate testing, easy operation, and multifunctionality. It is an indispensable and important tool in modern production. How to choose a suitable water activity meter? SISCO will provide price ranges and descriptions for different types of water activity meters.
