The visualization and quantification of the cooking of rice by NMR
imaging is reported for Japonica rice (Oryza sativa. L. Japonica
cv. Nipponbare) as a test sample. Rice was cooked in a vial for various
times and then studied at room temperature by NMR imaging. The multi
slice multi echo method was employed to obtain two-dimensional proton
images. Images using only the first echo clearly revealed the changes
in the water content of the rice grains during cooking. T2 images
were obtained from the same experiments but using the first 16 echoes
and converted to images of the water distributions using an empirical
T2 vs. water content calibration determined from a series of reference
water/rice starch mixtures. The total limiting water content within
the rice grains was calculated and it agreed with that calculated
from the known water/rice ratio used, indicating that both the concentration
and distributions of water within the rice grains during cooking
obtained from the NMR imaging were quantitatively reliable. � 2004
