Water Activity & pH

;

What we test

Water activity is the amount of “free water” available for microbial growth in edible cannabis products. pH measures the acidity of cannabis edible products.
;

Why we test

These tests are performed to ensure quality and stability of edible cannabis products. A high water activity or pH can affect the flavor and consistency of a product, as well as allow microbial growth. These directly impact shelf stability and can cause products to go bad sooner.
;

How we test

Water activity is tested using a water activity meter or hygrometer, which measures the vapor pressure of water in a product and compares it to the vapor pressure of pure water. This determines the water activity, expressed as aW.
pH is tested using a pH meter, which measures the diffrence in electrical potential between two electrodes, one of which is a reference. This difference in potentials relates to the acidity of a solution, or the pH.
