Exposure of brown rice to plasma and rice storage
The design of low-pressure plasma is based on a previous
method (Chen et al., 2012). Samples of brown rice (20 g) were
placed in a 15-cm acrylic reactor. Rice samples were fairly evenly
distributed in the reactor, and a vacuum system provided a pressure
of 800 Pa. 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.
