. After reaching a suitable vacuum in the reactor, a
DC high voltage supply was operated at 1–3 kV with a constant
current of 1.2 mA for 10 min. Air was used as the discharge gas.
In our pre-tests, a treatment time of 10 min improved the germination
of the rice. Therefore, the process time was fixed at 10 min,
and the influence of different voltages on the germination of brown
rice was explored.
