A product isotherm is a graph showing how water activity changes as water is adsorbed into and desorbed from a product. Isotherms provide the specific data you need to:
Make mixing models
Set QA/QC specifications
Define critical control points
Do packaging calculations
Predict the effects of temperature abuse
Determine monolayer value
Maximize shelf life
Determine when caking and clumping will occur
Find glass transition and deliquescence points
Predict protective coating/layer permeability
Evaluate hygroscopicity
