is a sensitive test for measuring the production of malonaldehyde
(MDA) that was the secondary lipid oxidation product resulting from the degradation of lipid hydroperoxides (Aubourg, 1993). The
TBARS values of control and G50 group increased to a maximum on
day 9 and 12, respectively, and afterwards declined during the
refrigerated storage (Fig. 2B). However, the TBARS value of control
group was higher than that of G50 group throughout the whole
period of storage. The increase of TBARS in the first few days suggested
formation of secondary lipid oxidation products, while the
decrease in TBARS values also was a result of their reaction with
free amino acids, proteins and peptides present in the red drum
fillets, to form Schiff's bases, apart from the breakdown of the
malonaldehyde due to tertiary degradation (Maqsood & Benjakul,
2011; Pezeshk, Rezaei, & Hosseini, 2011).
The TBARS value of G100 group increased slowly along with
