| In this study, the influence of four cooking methods (baking, boiling, microwaving and frying) was
evaluated on the nutritional value of kutum roach. Proximate, fatty acid composition, vitamin and mineral
contents and also nutritional quality indices (NQI) of kutum roach were investigated before and after
cooking treatment. All treated samples showed increase in protein, ash and lipid contents and decrease
in the content of total omega-3 fatty acids (n-3) in comparison to raw fish fillets (control group). Cooking
methods had no significant effect on omega-6 fatty acids (n-6) except for frying that increased it.
Nonetheless, all of the cooking methods reduced vitamin B1, A and D contents. Boiling significantly
decreased mineral contents including Na, K, P and Zn.
Considering the overall nutritional quality indices, vitamin and mineral contents, baking is the best
cooking method among other applied methods. |
