Webinar Description

Moisture interaction plays a critical role in food quality, processability, and stability, directly dictating key attributes like crispness, flowability, and microbial safety. Understanding these moisture-material behaviours at varying relative humidities is essential for preventing unwanted texture changes, clumping, and premature spoilage. Dynamic gravimetric Vapor Sorption (DVS) serves as a premier analytical technique for measuring how raw ingredients and final formulations absorb and desorb moisture. By using high-precision microbalances to continuously record mass changes under precisely controlled environmental conditions, DVS delivers rapid, real-time insight into water-solid interactions that traditional loss-on-drying methods often miss.

In this presentation, Surface Measurement Systems will present an educational webinar based around the well-established technique of Dynamic gravimetric Vapor Sorption (DVS).  This applications-oriented webinar will focus on the moisture sorption properties of food materials and its implications in process-development, pre-formulation and formulation development.  In particular, practical examples of using the DVS for sorption mechanism determination and modeling, drying kinetics, caking, powder flow and vapor-induced transformations will be discussed.  Finally, water vapor transmission rates (WVTR) and kinetic studies will highlight the DVS for packaging applications and shelf-life prediction.
