Additionally, stabilization of these bran fractions individually with middle infrared radiation and its effects on the contents of tocopherols and gamma-oryzanol were investigated. FFA content of the crude and stabilized bran fractions that were obtained from the last whitening and polishing steps was higher either in the beginning or in the end of the storage compared to the others obtained in the first steps of whitening. Stabilization at 700 W infrared (medium-wave) power for 7.0 min provided 90 days of shelf life without a notable change in FFA content of rice bran fraction which was obtained from the first whitening step. Total tocopherol and gamma-oryzanol contents of stabilized rice bran fractions were higher than their crude counterparts. (C) 2015 Elsevier Ltd.
