배합사료를 공급한 양식 넙치와 생사료를 공급한 양식넙치의 핵산 관련 물질 및 유리아미노산 측정을 통한 품질의 차이를 비교하였다. 넙치 등근육의 핵산관련물질은 모든 실험사료구에서 공통적으로 AMP 함량이 가장 높았고 그 다음으로 IMP의 함량이 높았다. 공급한 사료에 따라서 HxR의 성분에는 유의적인 차이(p
This study analyzed the taste components of dorsal muscle and fin muscle collected from olive flounder cultured with extruded pellet (EP) compared with those of olive flounder cultured with raw fish moist pellet (MP) as a control. The olive flounder in this study were cultured for 10 months with either the formulated extrude pellets (FEP), commercial extruded pellets (CEP) or the MP feed, and the average weight was 1.15 kg. The major nucleotides and related compounds in the dorsal muscles of the fish fed with MP, CEP and FEP diets were AMP and IMP. The fin muscle of the olive flounder contained the largest amounts of IMP(). The K value of the dorsal muscle in olive flounder fed with MP, CEP and FEP showed 9.63%, 9.83% and 5.84%, respectively. The free amino acids in the dorsal muscle of olive flounder showed significantly differences in the composition depending on the feed, but the distribution of free amino acids showed similar patterns. Among free amino acids, taurine showed the highest content in all the experimental groups, and the asparagine and citrulline contents were significantly higher in the groups fed with CEP and FEP than in the group fed with MP. The significant differences were observed in the contents of specific free amino acids in dorsal muscle and fin flesh depending on the feed for cultured olive flounder.
