There is increasing interest in developing flavor-enriched concentrate using byproducts of skipjack tuna Ktsuwonus pelamis as a replacement for commercial beef bone extract concentrate (CBB-EC). This study was compared on sanitary and nutritional characteristics between skipjack tuna frame extract concentrate (ST-EC) and CBB-EC as a control of skipjack tuna frame extract concentrate. The moisture contents of CBB-EC and ST-EC 41.4-4.9% and 45.3%, respectively. The results of viable cell counts and E. coli assays suggested that CBB-EC and ST-EC is a safe and sanitary for use in food. There were no differences in peroxide values among CBB-ECs. The total amino acid contents in CBB-EC and ST-EC were 25.6-29.3 g/100 g and 37.9 g/100 g, respectively, and the major amino acids present glutamic acid, proline, glycine, alanine and arginine. Regardless of kinds of the mineral, mineral contents of ST-EC higher than those of CBB-EC. The major fatty acids were 16:0, 18:0 and 18:1n-9 in CBB-EC, 16:0, 18:1n-9 and 22:6n-3 in ST-EC. These results can be used as background information to develop flavor-enriched concentrates from byproducts of skipjack tuna as replacement for CBB-EC.

We investigated the nutritional characteristics of the uncooked Skipjack tuna Katsuwonus pelamis frame (U-STF) as a basic resource for preparing flavor-enriching concentrates. The bone rate based on the fish frame (FF) was 53.2% in U-STF, thus lower than those of cooked skipjack tuna frame (C-STF), the uncooked salmon frame (U-SF), and beef leg bone (BLB). The composition of FF had 48.6-58.0% moisture, 18.4-21.3% crude protein, 7.0-15.0% crude lipid, and 12.8-22.1% ash. Compared to the proximate composition of BLB, that of FF was higher moisture and crude protein but lower solids, crude lipids, and ash. The total amino acid contents of FF was 17.6-20.8 g/100 g, which was higher than that of BLB. The levels of calcium and phosphorus of FF were 4.7-8.5 g/100 g and 2.4-4.2 g/100 g, respectively, thus lower than those of BLB. The brix concentration of FF extract was $5.0-8.2^{\circ}$, being highest in U-STF extracts, followed by extracts of U-SF and then extracts of C-STF. Our results indicate that U-STF is an optimal resource for preparing flavor-enriching concentrates.
New Cyclic Peroxides from a Sponge, Plakortis sp.
임치원,김진수,차용준 한국수산과학회 2005 Fisheries and Aquatic Sciences Vol.8 No.1
Two new cyclic peroxides were isolated from an undescribed sponge of the genus Plakortis sp. collected at Discovery Bay, Jamaica. The molecular structures were elucidated by interpreting 1D and 2D NMR and HRMS data. The cyclic peroxides, Compound 1 and 2, exhibited significant antimicrobial activity against pathogenic bacteria and fungi with IC50 values of 0.9-5.0μg/mL and 0.7-8.0μg/mL, respectively.
조리냉동식품의 가공 및 저장중 품질안정성 : (I) 정어리버어거의 가공

정어리버어거를 가공하기 위하여 쵸핑한 정어리 육에 대해 분리대두단백 : 물 : 대두유(16 : 80 : 45)로 만든 유화커어드 14.1%, 식염 1.5%, 모노글루탐산나트륨 0.1%, 설탕 2.0%, sodium bicarbonate 0.4%, 중합인산염 0.2% 빵가루 8.0%, 분리대두단백 3.0%, 양파가루 0.3%, 생강가루 0.15, 후추가루 0.1%를 첨가하여 정어리육 알맹이가 붕괴되지 않도록 혼합한 후 튀긴($165{\pm}2^{\circ}C$, 3분) 것이 가장 좋았다. 정어리버어거의 수분함량은 62.7% 조단백질 17.7%, 조지방은 14.9%로 유화커어드를 첨가하므로서 원료어 지질의 변동에 관계없이 조지방 함량은 $14{\sim}15%$ 범위로 조정 가능하였다. 제품의 주요 구성지방산은 16 : 0, 18 : 1, 20 : 5 및 22 : 6 등으로 고도불포화지방산이 많이 함유되어 있었고, aspartic acid, glutamic acid, leucine, lysine 등과 같은 아미노산의 함량이 많았다. 정어리버어거는 histidine을 주체로 하는 유리아미노산과 IMP를 주체로 하는 핵산관련물질이 주요한 맛성분이고 여기에 total creatinine, betaine 및 TMAO가 보조적으로 정어리버어거의 맛에 관여하리라 판단된다. The processing conditions and food components of meaty textured sardine burgers were studied to develope a new form of burger, The separated sardine meat was chopped, mixed with 14.1% emulsion curd, 1.5% table salt, 2.0% sugar, 0.4% sodium bicarbonate, 0.2% polyphosphate, 0.1% monosodium glutamate, 8.0% bread powder, 0.4% onion powder, 0.1% garlic powder, 0.1% ginger powder and 3.0% soybean protein by remodeled stone mortar. This seasoned sardine meat was fried in soybean oil $(165{\pm}2^{\circ}C,\;3min)$. The main fatty acids of sardine burger were palmitic acid, oletic, acid, linoleic acid, eicosapentaenoic acid and docosahexaenoic acid. Amino acid composition of sardine burger were mainly consisted of histidine, glutamic acid, leucine and lysine. The major taste compounds in the product were revealed nucleotides and their related compounds $(11.19{\sim}11.96\;{\mu}mole/g)$ such as IMP and free amino acids (1824.8 mg/100g) such as histidine, glutamic acid, leucine and lysine. Total creatinine, betaine and trimethylamine oxide were seemed to act an auxiliary role in taste of product.
