Noninvasive Magnetic Resonance Imaging (MRI) was used to study the
moisture removal pattern inside a single grain of wheat (cultivar:
A.C. Barrie) during drying. Images were obtained using a conventional
spin-echo pulse sequence on an 11.7 Tesla MR spectrometer equipped
with a drying apparatus. Samples of intact kernels (with all three
components: pericarp, embryo, and endosperm), mechanically scarified
kernels, and kernels with the embryo-removed were dried at different
temperatures to study the influence of kernel components on the internal
moisture removal and distribution pattern. MR images were recorded
at equal time intervals and moisture patterns were analyzed from
the MR images of wheat kernels. Analysis of the images revealed that
moisture loss from the seed parts differed significantly during drying
and was dependent upon the grain components.
