  1. Data represent the mean ± SD, n = 10. Vehicle, L, M and H express that the fillets has been treated with 0 mg/ml, 15 mg/ml, 25 mg/ml and 35 mg/ml of MFESI, respectively. Different letters indicate significant between-group differences, abc p < 0.05. Asterisk expresses significant intra-group differences compared to the treated sample with MFESI for 0 h, * p < 0.05
