title: [Physical and antioxidant characteristics of black (Brassica nigra) and yellow mustard (Brassica alba) seeds and their products].
abstract: The composition, some physical properties (density, refraction index, and color), antioxidant capacity (DPPH), and fatty acid profile of seeds of black (Brassica nigra) or yellow mustard (Brassica alba) were evaluated, as well as for their oils and residues from oil extraction. Density of the black and yellow mustard oils were 0.912 ± 0.01 and 0.916 ± 0.01 g/mL, respectively; their refraction indexes were 1.4611 ± 0.01 and 1.4617 ± 0.01, respectively; being not significantly different (p > 0.05) between two mustards. Color parameters of the black and yellow mustard oils presented greenish-yellow tones and reddish-yellow tones, respectively; regarding antioxidant activities, these ranged from 25 mg equivalents of Trolox/100 gin the yellow mustard oil to 1,366 mg equivalents of Trolox/100 g in the residues from oil extraction of black seed mustard. The fatty acid profile of the black mustard seed revealed that its predomipant fatty acid is oleic (22.96%), followed by linoleic (6.63%) and linolenic (3.22%), whereas foryellow mustard seed the major fatty acid is erucic (6.87%), followed by oleic (5.08%) and linoleic (1.87%) acids.
