Abstract:
Because of the long production time and the low production efficiency in the production of germinated brown rice. The influence of different pretreatments on the germination of brown rice was studied to find out the new ways of improving the germination rate of brown rice. Early indica rice as material, five kinds of processing (short-term soaking, ultrasound, stirring-soaking, ozone, and microwave) were applied to study the influence on the germination rate and GABA content in different germination time (6, 8, 10, 12, 14h) . The results showed that, compared with the brown rice of non-treatment, the five kinds of pre-processing methods can significantly improve the germination rate and GABA content of brown rice (p<0.05) . The influence of germination rate of brown rice:ozone (22.2%) >stirring and soaking (15%) >ultrasound (14.8%) >microwave (11.3%) >short-term soaking (10.3%) , and the influence of GABA content of brown rice:stirring and soaking (11.59mg/100g) >ozone (6.08mg/100g) >ultrasound (5.63mg/100g >microwave (4.9mg100g) >short-term soaking (2.95mg/100g) . As a result, ozone and stirring-soaking processing were the most advantageous for the production of germinated brown rice. Meanwhile, the two kinds of processing have the low cost, less energy consumption and are easy to implement, so they tried to have an application in production.
