Hydrothermal treatment of rough rice: effect of processing conditions on product attributes
A method involving hydration, tempering and heating steps is presented to process rough rice as alternative to traditional parboiling with pressure steam. The effects of temperature (66–84 °C), tempering time (60–420 min) and heating time (30–180 min) on gelatinization degree and milling yield were...
