A spin-echo (SE) magnetic resonance imaging (MRI) technique was used
to study non-invasively moisture levels as a function of time in
single wheat kernels. Internal moisture distribution during drying
of wheat at temperatures of 30, 40, and 50 �C for 4 h was analysed
from the MR images. The influence of the individual wheat components
on the drying process was observed using physically different wheat
kernels: intact kernels, mechanically scarified kernels with incisions
in the pericarp, and kernels with the embryo removed. Drying rate
curves for these different kernels were obtained at three different
temperatures and the effects of temperature on the drying curves
were discussed. A calibration curve of MR image intensity versus
the moisture content of the grain was obtained using nuclear magnetic
resonance (NMR) spectra of wheat at different, known, moisture contents.
Results obtained from this study provided details of the drying kinetics
in wheat kernels. � 2007 IAgrE.
