This study was carried out to determine the reasonable conditions of brown rice conditioning using thin layer conditioning method. The paper describes the rate of water absorption, property of brown rice, electric energy consumption and property of milled rice under the conditions such as initial moisture content of brown rice, air temperature, air humidity and rice variety.
The rate of water absorption increased with the the decrease of brown rice moister content or incease of air temperature and air humidty. It was found that the difference of water absorption rate was found among varieties. Generally speaking, the rate of water absorption of full ripeness browh rice was increased. The electric energy consumption and an unstriped embryo rate was decreased accoring to the conditioning.
There was found a correlation between the rate of broken kernel and the rate of cracking. An increase in fatty acid was not effected by conditioning.
