Oxidative stability of bran lipids from rice variety (Oryza sativa (L.)) lacking lipoxygenase-3 in seeds


, : Oxidative stability of bran lipids from rice variety (Oryza sativa (L.)) lacking lipoxygenase-3 in seeds. Journal of Agricultural and Food Chemistry 44(11): 3479-3483

Rice Daw Dam, which lacks LOX-3 (lipoxygenase-3) in its seed, and Koshihikari and Koganemochi (which have normal LOX-3 activity), were used to investigate the oxidative stability of lipids in rice bran fractions during storage at 4 and 37 degrees C. Free fatty acid content in lipids differed between storage temperatures and peroxide value (POV) differed between cultivars. Differences between cultivars and between storage temperatures in carbonyl value (COV) in lipids were also observed.
