Selected Quality Attributes Of Frozen Farmed Giant Grouper (Epinephelus Lanceolatus) As A Function Of Storage Temperature, Wen-Chieh Sung, Jing-Rong Lin, Tze-Kuei Chiou, Yu-Wei Chang

Journal of Marine Science and Technology

The effects of storage temperature (-20°C, -30°C and -55°C) on selected quality-related characteristics of vacuum packed frozen giant grouper fillets (Epinephelus lanceolatus) stored for 6 months were evaluated. The following quality attributes were measured: proximate composition, pH, thiobarbituric acid (TBA) value, total volatile basic nitrogen (VBN), ATP related compounds, K value, microbiological analysis, color, texture and sensory evaluation. Formation of TBA was low in the giant grouper fillet, with a value of less than 3.91 mg malondialdehyde (MDA) kg-1, after 6 months storage at -30 and -55°C. No significant differences were found in pH, total plate count (TPC), white index …
