Application of broadband acoustic resonance dissolution spectroscopy (BARDS) to the gas release behaviour during rehydration of milk protein isolate agglomerates

“…4 and 5, with return times being about 450 s for the MPI powders and greater than 800 s for the higher concentrations. This is consistent with work conducted byVos et al (2016).…”

“…So theoretically, the rehydration process of a dissolving powder can be described acoustically by BARDS. The first application of BARDS to the rehydration of dairy powder was reported for MPC powders with protein contents ranging from 35 to 90% (Vos et al, 2016). Rehydration of the different MPCs was monitored using BARDS, from which their rehydration characteristics were acoustically distinguished.…”

Applications of ultrasound for the functional modification of proteins and nanoemulsion formation: A review

“…4 for a high-protein dairy powder: (1) Wetting, (2) Swelling, (3) Sinking, (4) Dispersion and (5) Dissolution . The key stages where power ultrasound could affect the rehydration process is that of dispersion, the fragmentation of wetted powder particles, and dissolution, the complete breakdown of granular structure and release of constituent molecules (Vos et al, 2016).…”

Sounding out falsified medicines from genuine medicines using Broadband Acoustic Resonance Dissolution Spectroscopy (BARDS)

“…The genuine dissolution profile returned to steady state at 157 s while the falsified sample returned to steady state at 282 s. BARDS data is highly reproducible and the average standard deviation across spectral data points of triplicate measurements is ~ 0.122 kHz. This allows for a reduction in replication to duplicate measurements with an average % variance of ~ 2.0% 30 , 31 . The data of both samples in Fig.…”

“…In a typical BARDS analysis, the spectrometer records the steady state resonances of the system as a background reference for 30 s, before the sample is added and the stirrer is set in motion. The pitch of the resonance modes in the solution change significantly when the sample formulation is added before gradually returning to steady state over several minutes 30 , 31 . The received samples were of different formulations.…”
