본 연구에서는 국내에서 판매되는 24개 건어포 및 조미 건어포 제품의 종 판별 및 표시사항 준수 여부를 평가했 다. 이러한 수산가공품에 사용된 원재료의 종판별을 위해 cytochrome c oxidase subunit I 및 cytochrome b 유전자 의 염기서열을 분석하여 NCBI GenBank 및 BOLD 데이 터베이스에 등록되어 있는 생물종의 염기서열과 비교 후 계통 분석을 수행했다. 분석 결과 13개 종(Hyporhamphus quoyi, Gadus chalcogrammus, Lophius litulon, Conger myriaster, Paramonacanthus pusillus, Hyporhamphus sajori, Gadus macrocephalus, Hoplobrotula armata, Callionymus meridionalis, Liparis tanakae, Dosidicus gigas, Lagocephalus cheesemanii, and Takifugu vermicularis)이 확인되었다. 일반 명(장어, 오징어 등)을 포함할 경우 16개 제품(66.7%)에서 표시사항과 판별된 종 간에 불일치가 확인되었으며, 일반 명을 제외할 경우 불일치 비율은 41.7%로 감소했다. 식품 유형별로는 조미건어포 제품(n=20, 70%)에서 건어포 제품 (n=4, 50%) 보다 높은 비율의 불일치 비율이 관찰되었다. 원산지별 분석 결과 특정 국가와 불일치 비율과의 상관성 은 확인할 수 없었다. 이러한 연구 결과는 건포류 제품의 주기적 모니터링 수행 및 수산물의 국명 표시 선을 위한 기초자료로 쓰일 수 있을 것이다.

In this study, we evaluated species identification and labeling compliance of 24 dried seafood products sold in South Korea. To determine the species used in these processed seafood products, sequences of cytochrome c oxidase subunit I and cytochrome b genes were analyzed and compared with reference sequences from the National Center for Biotechnology Information (NCBI) and the Barcode of Life Data Systems (BOLD system), followed by phylogenetic analysis. The identified species were Hyporhamphus quoyi, Gadus chalcogrammus, Lophius litulon, Conger myriaster, Paramonacanthus pusillus, Hyporhamphus sajori, Gadus macrocephalus, Hoplobrotula armata, Callionymus meridionalis, Liparis tanakae, Dosidicus gigas, Lagocephalus cheesemanii, and Takifugu vermicularis. Discrepancies between the labeled and identified species were found in 16 products (66.7%) when generic market names (e.g., unagi and squid) were included; this discrepancy rate reduced to 41.7% when generic market names were excluded. The discrepancy rate was higher for seasoned and dried seafood products (70%) than that of dried seafood products (50%). No significant correlation was observed between the country of origin and the discrepancy rate. These results provide important baseline data for the regulatory monitoring of dried seafood products, and could aid in improving the accuracy of species labeling in the seafood industry.
