Experiments were conducted with an automatic
rice cooker (SR-DG 182, 1.8L, 600 W, 220 V, 50 Hz,
Panasonic Management Co., Ltd. Thailand). Two
hundred grams of brown rice were soaked in a pot for
10 min with 300 ml of deionized water. After the rice
was cooked for 60 min, a thermostat coupled with
a microswitch automatically switched off the rice
cooker. Then the cooked brown rice was moved from
the rice cooker to a stainless template (4 cm diameter
x 1 cm high). All samples were placed on a stainless
tray for 30 min at 30o
C before microwave drying
