Food

Food and food ingredients can absorb up to 50% by mass of moisture from the air

Food and food ingredients are often very hygroscopic materials. The final performance and stability of these materials necessitates careful consideration of moisture uptake in the materials, as well as the associated packaging system. Problems with drying, caking, product stability are common and can often be traced to moisture issues. Water sorption isotherms obtained using our DVS instruments is industry standard way of understanding these challenging problems.

Drying and dehydration
The moisture sorption properties of many solid state materials, especially organic materials are critical for the characterisation of their drying and shelf life stability. In the past 10 years the DVS method invented by Surface Measurement Systems has become the standard laboratory method for studying drying and dehydration behaviour.
