To reduce water activity, you can # dry the food # add sugar # add salt To increase water activity, add water.
high water activity neutral ph
The water activity of fats is typically very low, close to zero, since fats do not contain water molecules. Water activity is a measure of the amount of available water for microbial growth, and since fats do not provide any water, their water activity is minimal.
low water and low ph
Hi, NOVASINA AG-Switzerland manufactured Water Activity Meter is advised. Suman rsuman@eeipl.in
It is easy to see the shortfalls of high water activity when you look at water activity only as a way to control the growth of bad bacteria, but what if you want bacteria to actually grow in your product? The other thing is that texture depends upon water activity, so if you need to change your texture, you could raise the water activity. Another thing that is important to remember is that browning reactions occur at different water activities and you can change the water activity to control browning reactions.
Water activity will be variable depending upon the recipe and the amount of NaCl used.
Water activity is a measure of the amount of water available for biological reactions and microbial growth in a substance. It is calculated as the ratio of water vapor pressure in the substance to the vapor pressure of pure water at the same temperature. A lower water activity value indicates less available water for microbial growth.

There are many natural resources that are extremely important to human activity, but without water human activity could not exist. Therefore, water is vital.
The water activity in honey is typically around 0.6, which is too low to support the growth of most microorganisms. This low water activity helps give honey its long shelf life and resistance to spoilage.
