Abstract
Moisture-tempering is typically performed prior to first break in wheat milling operations to enhance separation of bran, germ, and endosperm. To improve the milling performance and to increase yield, a better knowledge of moisture distribution and migration in individual wheat grains during tempering is essential. The research described herein was conducted to demonstrate the non-destructive measurement of the three-dimensional (3D) distribution of moisture in a single wheat grain. A 3D magnetic resonance imaging (MRI) technique was adapted for the probing of single wheat grains at storage moistures (c.12% wet basis). The technique is demonstrated in this report on one grain. A 3D projection reconstruction (3DPR) technique was used to acquire high resolution proton density images. The spatial resolution of the images was 94×94×94 μm3. The 3D proton density images were related to the 3D moisture distribution in the wheat grain. At 12% moisture content, the moisture distribution in the starchy endosperm of the wheat was not uniform. The variation of the moisture distribution was from 7·3% to 16·4% wb.
