Rice is a hygroscopic substance, meaning it absorbs moisture. In the presence of high relative humidity (RH), when dry rice is exposed to air, the rice grains will absorb water from the air (re-wetting). When wet rice is exposed to low relative humidity air, the rice grains leak water into the atmosphere (drying).
