DVS (DVS-Intrinsic, Surface Measurement Systems, London, UK) was used to analyse the moisture sorption profile of the powders. For each sample, 5 mg of powder was exposed to a dual moisture ramping cycle of 0 to 60% relative humidity (RH). The criterion for equilibrium moisture content at each RH was defined as dm/dt of < 0.02% per minute.
