Copper levels in germinated BR has been scarcely investigated,
although it is of great importance to maintain enzyme activity, to
prevent anaemia disease and cell damage, and to be involved in
skin and hair pigmentation (de Lima et al., 2014). Copper showed
relatively low values for soluble fractions but represented high
bioaccessibility expressed as solubility, indicating that the
bioaccessibility of copper showed little relationship with its
concentrations in the germinated samples. The highest copper
bioaccessibility was observed in GBR-HP1 (17.48 ± 0.08%),
decreasing in the order of GBR-HP5 (16.94 ± 1.56%), SBR-HP0
(16.09 ± 0.39%), GBR-HP0 (15.51 ± 0.52%), and GBR-HP3
(14.12 ± 0.62%).
