Abstract | This research has investigated the effects of varying drying temperatures on the physicochemical properties ofgerminated brown rice (GBR). The GBR samples were prepared in accordance with the prior research findings by which brownrice was soaked at 40 oC for 4 hrs prior to incubation at 40 oC and 90%RH for another 20 hrs. The resulting germinated brownrice was then divided into two groups and subjected to two different treatments: the steamed drying (SDR) and non-steameddrying (NSD) groups. The SDR group refers to the GBR samples steamed at 100 oC for 10 min prior to individually drying attemperatures of 20, 40, 80, and 160 oC, while the NSD group consists of the rice samples dried at the same temperatures withoutpre-steaming. The physicochemical properties of the GBR samples were subsequently analyzed to identify the optimal treatmentcondition. The findings revealed that the drying temperatures influenced the physicochemical properties of both GBR groups.The apparent hardness, water absorption and free fatty acids of both GBR groups were lower than those of the non-germinatedbrown rice, whereas their total lipids were higher. Besides, the higher drying temperatures had an adverse effect on the GABAcontent. |
