  • This study analyzed the proximate compositions, total amino acids, and fatty acid compositions in muscle and viscera of 51-month-old triploid and diploid Pacific abalone, Haliotis discus hannai. Proximate composition analysis showed that the muscle of diploid abalones had a higher protein and ash ratio than that of triploid abalones, while there was no significant difference in the ratios of moisture and fat (P>0.05). The triploid abalones had a significantly higher ratio of carbohydrate in muscle than the diploid abalones (P<0.05), which suggests that the transference of carbohydrates from muscle to gonad is decreased in sterile triploid organisms. Amino-acid analysis indicated that the total content was 133.42 mg/g in diploid muscle and 151.46 mg/g in triploid muscle. Taurine, arginine, glutamine, glycine, glutamic acid, alanine, and leucine, which are the major amino acids in abalone, were measured as 84.64 mg/g in triploid muscle and as 73.92 mg/g in diploid muscle. The essential amino acid content of triploid muscle (38.83 mg/g) was significantly higher than that of diploid muscle (31.94 mg/g) (P<0.05). Saturated fatty acids and monoene fatty acids were abundant in triploid muscle and polyene fatty acids were abundant in diploid muscle. Therefore, triploid Pacific abalone appears to be a good nutritional food source.

  • 전복(Haliotis discus hannai) 내장(內臟)에 함유(含有)되어있는 carotenoid에 관(關)하여 시험(試驗)하였다. 우리나라 근해단(近海岸)에서 채취(探取)된 전복의 내장(內臟)을 acetone-methanol (4 : 1) 혼합용매(混合溶媒)로 추출(抽出)하고 이 추출액중(抽出液中)의 carotenoid를 silica gel TLC, $Mg(OH)_2$ 여과지(濾過紙) chromatography 및 $Mg_2(OH)_2CO_3$ TLC에 의하여 분리정제(分離精製)하였다. 분리정제(分離精製)한 11종(種)의 carotenoid에 대(對)하여 epoxide test, partition ratio 측정(測定), $NaBH_4$에 의한 환원(還元), 알카리처리(處理), 표준(標準) carotene와 비교시험(比較試驗), electronic absorption spectrophotometry, 및 infrared spectroscopy 등(等) 여러가지 시험(試驗)은 하였다. 확인(確認)된 carotenoid는 ${\alpha}$-carotene, ${\beta}$-carotene, lutein, zeaxanthin, siphonaxanthin, siphonein fucoxanthin, loroxanthin 유사물(類似物) 및 fucoxanthinol 류이물등(類似物等) 9종(種)이며 이 밖에 2종(種)의 미량(微量) carotenoid는 확인(確認)되지 못했다. fucoxanthin은 특(特)히 KOH처리(處理)에 의하여 fucochrome이나 semifucoxanthol과 동일(同一)한 chromophore를 갖는 산물(産物)로 변환(變換)됨을 발견(發見)하였다. 전복 내장(內臟)에서 확인(確認)된 색소(色素)들 가운데siphon-axanthin, siphonein, fucoxanthin, loroxanthin 유사물(類似物) 및 fucoxanthinol 유사물(類似物) 등은 지금까지 패류(見類)에서 발견(發見)되었다는 보고(報告)가 없다.
