One would not normally expect there to be a connection between food physics and geotechnical engineering, but there are several. Decagon builds instruments for measuring water activity in foods and for characterizing food moisture relations. We also build instrumentation for geotechnical engineering. In many cases the instruments are the same. Decagon recently introduced the AquaSorp IG isotherm generator to research markets in foods and pharmaceuticals. This report briefly discusses results of experiments using the AquaSorp IG to measure isotherms of soils.
