      abstract     = {The redistribution of water in prototype food systems,
                      comprising phases with contrasting water activity (A(w)),
                      was investigated. To accomplish this task, MRI techniques
                      adapted to migration rate were used. RARE and SPI measuring
                      methods were used to monitor water redistribution in crunchy
                      inclusions in water and biscuit shells with apple filling
                      during storage, respectively. In the first case, fast
                      miaration, which typically last some tens of minutes, was
                      monitored with a temporal resolution 3.5 min or better,
                      while in the second case of slow migration it was monitored
                      during 2 months with 10 days temporal resolution. 3D MR
                      images with sub-millimeter resolution visualise the spatial
                      redistribution of moisture and allow a quantification of its
                      rate and extent of matrix swelling. Correlation with high
                      resolution X-ray (XRT) images allows to identify structural
                      elements responsible for unwanted fast hydration.The
                      obtained results demonstrate the potential of a combined
                      MRI/XRT approach for dynamical monitoring of the migration
                      of moisture into porous cereal material in a broad range of
                      A, contrast and hydration levels. The measured migration
                      rates through samples of different internal structures can
                      be used for validating models for prediction of water
                      redistribution in multiple phase systems in a quantitative
                      manner. (c) 2007 Elsevier Ltd. All rights reserved.},
