2.6.4. Sensory evaluation
Sensory attributes of the coated rainbow trout fish fillets were evaluated after frying in corn oil at 170 C for 5 min, by a panel of ten experienced panelists (25e30 years old, male). The following sensory characteristics were studied: appearance, color, odor, taste, and tenderness of fish fillet. The scale employed for evaluating the sensory quality of ethe fish fillet was a 10-point scale as described by Lima Dos Santos, James, and Teutscher (1981). The scores, in decreasing order, were 10e9 for excellent, 8e7 for good, 6e5 for fair and acceptable, 4e3 for poor and 2e1 for very poor (El-hanafy, Shawky, & Ramadan, 2011). The mean scores given by the panel indicated the overall sensory quality (Huss, 1995). A score of less than 4 implied that the fish was rejected.
