Water activity (Water Activity, abbreviated as aw, also known as water activity, water activity) mainly reflects the amount of free water in the food equilibrium state, reflects the stability of food and the possibility of microbial reproduction, and can cause changes in food quality Chemical, enzymatic, and physical changes are often used to measure the ability of microorganisms to tolerate dryness. By measuring the water activity of food and choosing a reasonable packaging and storage method, the use of preservatives can be reduced, and the shelf life of food, grain, fruits and vegetables can be judged.
