Water Activity Testing
Measure the free water available in your product – a key factor in preventing microbial growth and spoilage.

Equipment: Agilent
Why It Matters
Water activity is different from moisture content – it measures how much of that water is available for microbes to use. This is one of the best predictors of shelf stability. High water activity means your product is at risk for mold, yeast, and bacterial growth. Low water activity means better stability and longer shelf life.
