Dissolving The Method: A Critical Look at Powder Solubility Testing

Presenter

Thom Huppertz, FreislandCampina, NL, UCC Ireland

Webinar Description

Solubility is among the most frequently reported quality attributes of dairy powders, but what do commonly used methods actually determine? Dissolution is not a single event: it involves wetting, sinking, dispersion, disintegration and molecular dissolution, each influenced by the powder, the liquid and the conditions of reconstitution. Different testing methods capture different parts of this process and may therefore produce very different answers to the apparently simple question: Is this powder soluble?. This webinar will return to the underlying physical principles of powder dissolution and critically examine what established solubility, dispersibility and sedimentation methods measure. It will explore how sample preparation and test conditions shape the result, what an insoluble fraction actually represents.
