The effects of thermal processing techniques on the antioxidant activity of the selected Brassica vegetables measured by the FRAP antioxidant assay. The bars represent means ± standard deviations (n = 3). The different letters for each vegetable indicate statistical differences based on a two-way analysis of variance. mM, millimoles; g, gram; TE, Trolox equivalent; AF, air-fry; FD, freeze-dry; FRAP, ferric reducing antioxidant power.
