Abstract: Methods for producing refined rice bran oil that include caustic treatment step(s) in an amount that is less than or equal to a theoretical amount of caustic required to neutralize practically all of the free fatty acids in the rice bran oil, but avoiding addition of excess caustic. An objective is to retain a high level of oryzanol in the refined oil.

Abstract: A process of producing a high-stability parboiled rice product which is not quickly rehydrated, but which is highly resistant to breakdown during long periods of steamtable exposure. The parboiling process comprises a hot water soak followed by steaming to effectuate substantially complete gelatinization. The rice is then pre-dried at an elevated temperature and tempered for an extended period of four to six hours. Plural stages following tempering reduces stress and thus enhances kernel integrity.
