The Cu content of raw kutum roach was 0.23 mg/kg. Boiling and
microwave cooking methods had no significant effect on the Cu
content, while baking and frying significantly increased this mineral
(P < 0.05). Ersoy and Özeren (2009) reported that none of the
cooking methods had a significant effect on the Cu content of African
catfish and according to Gokoglu et al. (2004), the Cu content of
fried rainbow trout increased significantly, but the effect of other
cooking methods was insignificant.
