Paralytic shellfish poison (PSP) occurrence and variation in the different bivalve species including oyster, Crassostrea gigas and mussel, Mytilus edulis in Jinhae bay Korea from January to December in 1997 were surveyed. And also compositional characteristics of PSP ingredients in the different bivalve species were investigated. PSP in shellfish was detected from late February and increased continuously until the middle of April in Jinhae bay. And after April PSP level had been decreased gradually and the toxicity was not detected by mouse bioassay in the early of June. Of the examined bivalve species, PSP content in the mussel exhibited the highest value and the PSP content in the mussel in the middle of April, PSP high season in Jinhae bay, was 6 times higher than that in the oyster. Gonyautoxin (GTX)1-4 group occupied 59.0-78.8% of whole PSP contents and identified as dominant ingredient in the examined bivalves except oyster. And it is also identified that the PSP toxicity in the tested species were derived from the GTX group. And the dominant ingredient of PSP in the oyster was carbamoyl-N-sulfo-llα- hydroxysaxitoxin sulfate(C1)(37.9%) and neosaxitoxin(neoSTX)(26.2%). But the toxicity of C1 in the tested oyster could be ignorable and most toxicity (80.0%) was derived from saxitoxin (STX) group.

Totally, twenty seven specimens of tiger puffer, Fugu rubripes rubripes were collected at Jagalchi fish market in Pusan, Korea during January, April and September in 1995. Anatomical distribution of pufferfish toxin in tiger puffer was examined by mouse bioassay. The frequency rate of toxic specimens containing ≥ 10 MU/g was 14.8% in liver; 16.7% in gonad; and 14.8% in skin, and no toxin was detected in muscle. The highest toxin level found was 160 MU/g in liver, 600 MU/g in gonad and 26 MU/g in skin, and each average toxin level (mean ± standard error) was 7 ± 6, 50 ± 35 and 5 ± 1 MU/g, respectively. Some specimens collected in January and April were toxic, while none of the specimens collected in September showed its toxicity. Although toxicity of tiger puffer showed the seasonal variation, tested tiger puffer was evaluated as a safe seafood for consumption, in that an acceptable level of toxin was found in the edible muscle and skin.

수산불(멍게, 키조개, 가리비, 자가비, 황석어, 도미, 낙지, 병태, 전어, 가오리, 숭어, 홍어, 갈치 및 멸치) 14종을 첨가한 배추김치의 레시피를 확립하여 제조하였고 저온숙성 7일차의 시료를 취하여 일반성분, 비타민, 무기질, 구성 및 유리 아미노산 함량을 조사하였다. 수산물을 첨가하여 제조한 배추김치 14종의 수분함량은 82.09~88.56% 범위였고, 조지방 함량은 0.31~0.64%, 조회분 함량은 2.70~3.50% 범위를 나타내어

시판되고 있는 일반 과메기(CK), 키토산을 첨가한 과메기(KAC) 및 금박을 입힌 과메기(KOGL)에 대한 일반성분, 무기질, 비타민, 지방산 및 구성아미노산 함량을 분석하였다. CK, KAC 및 KOGL의 일반성분을 분석한 결과, 수분(26.4~30.8%), 조단백질(29.1~32.7%), 조회분(1.6~1.9%)의 함량은 큰 차이를 보이지 않았으나, KOGL의 조지방 함량은 32.2%로 CK 24.5% 및 KAC 22.9%보다 상당량 높게

본 연구는 싱싱회를 , , 에서 15일 동안 보관하면서 3일 간격으로 pH, 총균수, 화학적 선도, 조직감, 관능평가를 살펴보고자 하였다. pH는 저장 직전 각각 6.25이였으며 냉장저장 시 시간이 경과할수록 점차 증가하였다. 냉동보관에서는 6일째까지 pH의 변화가 거의 없었고 저장 12일째에는 에서 6.48, 에서 6.55로 다소 증가하였다. 총균수는 냉장저장은 3일째 이후부터 이상 증가하였고, 냉동저장은 경과시간, 저장온도에 상관 없이 평
