Rice Grain Cross-Section (IMAGE) RMIT University Caption This image shows the concentration and distribution of zinc in one cross-sectioned grain of rice with no treatment (left) and another following soaking in water at 90C followed by steaming (right). The Australian Synchrotron's X-ray Fluorescence Microscopy beamline clearly showed researchers how zinc migrates to the center of the grain during this optimal parboiling approach, making the milled white rice more nutritious.
