In the semi-dry milling of rice, soaking is of great importance for the characters of rice flour. In this paper, the water absorption kinetics, hardness changes and related physicochemical properties of the glutinous brown rice (GBR) flour during soaking were studied to fit the Peleg equation. Different conditions (20–45°C, 0–12 h) were used in the soaking process of the GBR. The migration and distribution of water in the GBR during soaking process was analyzed by the low-field nuclear magnetic resonance (LF-NMR). Then, the regulation of wat...
