Investigating the dynamics of freeze-drying and annealing using in-situ synchrotron X-ray microtomography

Year: 2025

Type: article

Abstract: • Synchrotron X-ray microtomography enables in situ imaging of freeze-drying dynamics. • High-resolution imaging captures microscopic changes in ice and freeze-concentrate. • Annealing-induced cracks accelerate sublimation, improving drying efficiency. • Overlapping X-ray attenuation poses challenges for automated phase segmentation. • Final dry structure is determined by freezing and annealing conditions .
