초록
본 조사연구는 우리나라에서 주요 해산어로서 뿐만 아니라 식품원으로서, 또한 고급 경제 어종으로서 각광을 받고 있는 참돔, 조피볼락 및 넙치 등을 대상으로 동원한 지역에서 어적되는 친연산과 양식산으로 대별하여 이들의 품질평가를 정미성분에서 구명하고자 충무와 완도 2개 지역의 시료어를 채취하여 일반성분, 핵산관련물질 함량, 구성아미노산 함량, 유리아미노산 함량, 유기산 함량을 비교 분석하였다. 산지별로는 어느 시료에서도 큰 차이를 볼 수 없었으나 성장보건별로 보아 전체적으로 양식산 어류가 천연산어류에 비하여 조지방 함량은 높았고 수분 함량은 다소 낮은 경향을 보였으며, 조단백질과 회분 함량은 큰 차이를 볼 수 없었다. 핵산관련 물질 함량 중 ADP, AMP, IMP 및 inosine 등이 검출되고 ATP 및 hypoxanthine은 검출되지 않았으며 전체적으로 산지별, 성장조전별로는 큰 차이를 볼 수 없었으나 분석된 시료에서 공통적으로 IMP의 함량이 높았다. 구성아미노산은 총 17종이 검출되었으며, 분석된 시료에서 대부분 glutamic acid, lysine, aspartic acid, proline, leucine 등의 함량이 많았으며 cysteine, histidine, methionine, tyrosine, phenylalanine 등의 함량이 비교적 적었다. 그 외의 구성 아미노산 함량은 대체로 비슷하였다. 참돔과 조피볼락은 산지별, 성장조건별로 큰 차이를 볼 수 없었으나 넙치는 천연산이 양식산에 비하여 구성아미노산 함량이 많았다. 유리아미노산의 함량은 분석된 모든 시료에서 비슷한 경향을 나타내었고, 또한 산지별, 성장조건별로 큰 차이를 보이지 않았다. 그러나 전 시료에서 taurine이
This study was carried out in order to elucidate the fundamental data on the taste compounds between wild and cultured fishes produced on Chungmu and Wando at the southern coast areas of Korea. For this purpose, the food components of cultured fishes such as red sea bream Pagnus major, Sebastes pachycephalus and flounder, Paralichthys olivaceus being spot lighted for the main sea fish, the staple food and high economic fish were investigated and compared with those of the wild ones. There was a little appreciable difference in the proximate compositions of all the species from localities between wild and cultured fishes. But according to the growing conditions, wild fishes were higher in moisture contents and lower in crude lipid content than those of cultured fishes and little difference was seen in protein and ash contents between the two. With regard to the nucleotides and their related compounds, i.e. ADP, IMP and inosine were detected but ATP and hypoxanathine were not from them. On the other hand, there were little difference in the total taste compounds of all the species from localities and the growing conditions between wild and cultured fishes. But all the species were higher in IMP content. The total of seventeen amino acids were detected in samples. The highly contents of glutamic acid, lysine, aspartic acid, proline, leucine, alanine, valine and alginine were showed and less low contents of cystein, histidine, methionine, tyrosine and phenylalanine were detected. The total amino acids of the others were much alike in that composition. Little difference was seen from localities and the growing conditions between wild and cultured ones. The free amino acids were much alike in that composition of all the species. There was little difference in the free amino acid compositions all the species from localities and the growing conditions between wild and cultured fishes. But taurine was dominant, showing from 39% to 65% of the free amino acid content and it is followed by hydroxyproline, lysine, alanine and glycine in other. There were differences in the organic acid compositions of all the species from localities and the growing conditions between wild and cultured fishes. In addition, cultured fishes were more abundant in the total organic acid compositions than those of wild ones.
