Temperatures used for stabilization vary from 100 to
140 C. The bran is kept hot for 3e5 min after extrusion to ensure
lipase inactivation. The hot bran is then cooled using ambient air.
Dry extrusion was found more suitable for stabilizing bran to be
used as a food ingredient. The success of stabilization of rice bran
and its oil depends on temperature, duration of heat treatment,
moisture content of treatment medium, pH, and other parameters
(Orthoefer, 2005).
