대왕범바리(Epinephelus fuscoguttatus×E. lanceolatus)와 대왕자바리 (E. moara×E. lanceolatus)의 식품학적 품질비교

초록

The nutrient composition of the muscle of the hybrid grouper (Epinephelus fuscoguttatus×E. lanceolatus, HG) and the hybrid longtooth grouper (E. moara×E. lanceolatus, HLG) was measured as a function of body weight in this study. The crude protein and lipid levels in HG were 21.0–21.2 g/100 g and 1.9–3.4 g/100 g, respectively. HLG contained 20.6–20.7 g/100 g protein, and 3.9–5.5 g/100 g crude lipid. The total amino acid contents of HG were 18,829.7–18,980.2 mg/100 g and that of HLG was 17,793.7–19,293.7 mg/100 g. The mean saturated fatty acid content was 0.61–1.09 g/100 g for HG and 1.27–1.77 g/100 g for HLG. Monounsaturated and polyunsaturated fatty acid levels were 0.59–1.02 g/100 g (Monoene), 0.67–1.11 g/100 g (Polyene) in HG, which were lower than the 1.21–1.78 (Monoene), 1.22–1.69 g/100 g (Polyene) found in HLG. The highest mineral content (K and P) of HG was 510.13– 517.05 mg/100g and 231.59–247.67 mg/100 g, while that of HLG was 518.81–523.59 mg/100 g and 257.51–248.84 mg/100 g, respectively. In conclusion, there is potential for expanding the commercial utilization of HG and HLG as food resources as they are both nutrient-rich.
