Magnetic resonance microimaging (MRμI) is an outstanding technique for studying water transfers in millimetric bio-based materials in a non-destructive and non-invasive manner. However, depending on the composition of the material, monitoring and quantification of these transfers can be very complex, and hence reliable image processing and analysis tools are necessary. In this study, a combination of MRμI and multivariate curve resolution-alternating least squares (MCR-ALS) is proposed to monitor the water ingress into a potato starch extruded blend containing 20% glycerol that was shown to have interesting properties for biomedical, textile, and food applications.

- The study investigates how two types of potato starch—amorphous and glycerol-plasticized—react when immersed in water, focusing on their water absorption and structural changes.
- Using advanced techniques like wide-angle X-ray scattering (WAXS) and magnetic resonance microimaging (MRμI), researchers monitor how water enters the starch samples and deduce different diffusion mechanisms.
- The findings reveal that glycerol-plasticized starch exhibits behavior similar to Fickian diffusion, while amorphous starch aligns with a case II diffusion pattern, providing valuable insights for potential biomedical applications like implants.
