Abstract

Dehulled brown unmilled rice is exposed to ozone gas in an ozone and air gas mixture. The exposed brown rice is stored for at least a day to sufficiently affect the bran before subjecting the exposed rice to a typical milling process. The milling of the exposed brown rice results in reduced breakage and thus increased head rice yield to economically attractive levels.
