The distribution of starch-degrading enzymes in dormant rice grains was investigated with specific antibodies against α-glucosidases, α-amylases, and β-amylases. The α-glucosidases were predominantly localized in the inner endosperm. The α-amylases were mainly localized in the outer layers, and the β-amylases were distributed in whole grains. We propose a model to demonstrate how these enzymes degrade starch during rice cooking.
