  • 옥수수 배를 benzene(BZ), n-hexane(HX), petether(PE), tricholoroethhylene(TE), chloroform-methanol(2:1, v/v) (CM), dichloromethane-methanol(2:1, v/v) (DM), hexane-diethyiether(5:1, v/v) (HD)의 7종 용매로 조지질을 추출하여 SACC법으로 비극성과 극성지질을 분리한 후 각각의 지질 조성을 TLC scanner로 측정하고 GC로 지방산 조성을 조사한 결과를 검토하였다. 조지질 추출양은 DM에서 가장 많고 다음은 CM이며 중성지질은 HX, BZ, HD에서 높은 반면 PE, DM에서 낮았으며 함량비에서는 DM과 CM에서 높으며, 당지질은 DM을 사용했을 때, CM, PE, HX 등보다 높고 HD에서 가장 낮았고 인지질은 CM에서 가장 높게 나타났다. 중성지질의 분별정량에서 triglyceride는 DM에서 높고 PM에서 낮은 편이며 1, 3-diglyceride는 CM 에서 높고 DM에서는 낮았다. 총지질의 지방산 조성은 linoleic acid가 주요 성분이며 이는 CM에서 높은 편이며 oleic acid는 PE, HD등을 사용했을 때 CM보다 높고 중성지질의 지방산 조성도 linoleic acid가 가장 많고 BZ에서 높게 나타났으며, PE, CM, HD 등에서 낮고 oleic acid는 비슷하나 DM, BZ에서는 낮다. Palmitic acid는 CM, PE에서 가장 높게 나타났다.

  • 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.

  • A 10-week feeding trial with four dietary protein levels (22%, 32%, 42% and 52%) and two dietary lipid levels (8% and 17%) was conducted to investigate the optimum dietary protein and lipid levels for growth of long-nosed barbel fingerlings. Survival rate of fish was not affected by either the dietary protein or the dietary lipid level. Weight gain and feed efficiency were affected by the dietary protein level (P<0.01), but not by the lipid level, and increased with the dietary protein level at the both lipid levels. Weight gain and feed efficiency of fish fed the 52% protein diets with 8-17% dietary lipids were not significantly different from those of fish fed the 42% protein diets with 8-17% dietary lipids and 32% protein diet with 17% dietary lipid. Daily feed intake of fish was not affected by either dietary protein or dietary lipid level. Protein efficiency ratio and protein retention rate of fish fed the 32% protein diet with 17% dietary lipid were significantly higher than those of fish fed the 52% protein diets with 8-17% dietary lipids. Moisture content of fish fed the diets containing 8% lipid were higher than those of fish fed the diets containing 17% dietary lipid at each protein level. Crude lipid content of fish fed the diets containing 17% dietary lipid were higher than that of fish the fed the diet containing 8% dietary lipid at each protein level. The results of this study indicated that 32% protein and 17% lipid could be the optimum dietary level for growth of juvenile long-nosed barbel.

  • 시험 재배한 4가지 감자 품종(Irish Cobbler, Warba, Shimabara, Saco)을 동결 건조하여 분말을 만든 다음, 유리(遊離) 및 결합(結合) 지질(脂質)을 추출하고 이의 구성 지방질의 구성 부분을 관 크로마토그래피, 가스-액체 크로마토그래피 등의 방법으로 분리 정량하여 비교한 결과 다음과 같은 결론을 얻었다. 1. 감자의 건조물(乾燥物) 중 총(總) 조(粗) 지방(脂肪) 질량(質量)은 평균 0.57 %였으며 이중에서 유리(遊離) 지질(脂質)은 0.2 %였고 결합(結合) 지질(脂質)은 0.37 %로 결합(結合) 지질(脂質)의 함량이 유리(遊離) 지질(脂質) 보다 0.17%정도 많았다. 2. 유리(遊離) 지질(脂質) 중의 중성(中性) 지질(脂質) 함량은 14.9 %로 결합(結合) 지질(脂質) 중의 4.5 % 보다 약 3배 정도 많았고, 당지질(糖脂質)의 함량은 유리(遊離) 지질(脂質) 중에는 15.1 %로 결합(結合) 지질(脂質)중의 2.22 %보다 약간 적은 편이었다. 그러나 인지질(燐脂質)의 함량은 결합(結合) 지질(脂質) 중에는 33.9 %로 유리(遊離) 지질(脂質)의 7.2 %보다 4.5배 정도로 월등하게 많았다. 그러므로 감자 중의 결합(結合)은 주로 당지질(糖脂質)과 인지질(燐脂質)로 구성되어 있고, 유리(遊離) 지질(脂質) 중에는 중성(中性) 지질(脂質)과 당지질(糖脂質) 및 인지질(燐脂質) 함량이 서로 비슷하였다. 3. 총(總) 유리(遊離) 및 결합(結合) 지질(脂質)을 구성하는 주된 지방산은 모두 linoleic, palmitic 및 linolenic acids로 90 % 이상 이었다. 그러나 유리(遊離) 지질(脂質) 중에는 결합(結合) 지질(脂質) 보다 포화 지방산의 함량은 다소 적었고 불포화 지방산의 함량은 많은 편이었다.

  • 본 연구에서는 아위버섯의 일반성분 및 탄수화물, 섬유질, 무기질, 아미노산, 비타민, 유리당, 지방산조성 등을 조사하여 건강식품개발을 위한 기초자료로 활용하고자 실시하였다. 아위버섯의 경우 느타리버섯과 새송이버섯에 비해 수분은 적고 조단백질과 식이섬유가 많음을 보였다. 총 아미노산 함량과 무기질의 함량은 높게 나타났으며, 이는 아위버섯이 우수한 무기질 공급원의 식품이 될 수 있음을 보여주고 있다. 또한 아위버섯의 경우 느타리버섯, 새송이버섯에 비하여 수용성 비타민뿐만 아니라 지용성비타민의 경우도 많았으며 특히 비타민 C함량은 6배정도 많았고 특이하게 높은 glucose 함량을 보여주었으며 myristic acid등 포화지방산의 함량은 적은 반면, 불포화 지방산인 linoleic acid의 함량은 다소 높게 나타났다. 따라서 아위버섯은 풍부한 영양소를 가지고 있어 다양한 생리활성을 기대할 수 있으며 향후 기능성식품의 좋은 재료로 사용될 수 있는 가능성을 보였다.

  • The effect of Capricornidis Cornu (C.C) on the amount of total cholesterol, triglycerides, and phospholipid in serum from rabbit were observed. The preparations were extracted by methanol, and extracted samples were oraly adminstrated to the rabbits fasted for three days. After three days starvation, the amounts of total cholesterol and triglycerides in serum of the rabbit were markedly increased, while phospholipid was slightly decreased. The amount of total cholesterol and triglycerides were gradually decreased by adminstration of the extracted samples and were returned to the control leveles after 15 days. However, the amount of phospholipid was increased to higher than the control levels by adminstraion of the drug. According to the above results, it would be concluded that the extract of C.C. and crude drug preparation containing C.C. influences for the recovery of the increased amounts of total cholesterol and triglycerides by abnormal metabolism to the normal on rabbit.

  • The present study was conducted to characterize physicochemical properties of chub mackerel bones (CMB) to evaluate its potential as a food resource. The proximate composition of CMB showed 40.4% moisture, 13.8% crude fat, 15.2% crude protein, and 28.7% ash. The major minerals in CMB were calcium (26.27 g/100 g) and phosphorus (15.88 g/100 g). The amino acids were rich in glycine, proline, glutamic acid, and alanine. The contents of total and neutral lipids, glycolipid and phospholipid were shown to be 16.05%, 95%, 2.32%, and 3.15%, respectively. The major fatty acids were C22:6, C16:0, C18:1, C20:5, C18:0, C17:0, C14:0, C20:1 in order. The fatty acid contents of total and neutral lipid were in a range of 39.25% and 44.54% for saturated and 33.61% and 34.05% for polyunsaturated, respectively. The breaking strength and hardness of intact CMB were 10.01 and $50.03kgf/cm^2$, whereas those of CMB heated for 45 min at $121^{\circ}C$ were 0.40 and $1.94kgf/cm^2$, respectively.

  • A study was conducted to investigate the effects of dietary lipid sources on the growth and fatty acid composition of juvenile sea cucumber. For 12 weeks, three replicate groups of sea cucumber (average weight 1.4 g) were fed one of three diets, containing squid liver oil (SLO), soybean oil (SO), or linseed oil (LO) as a dietary lipid source, or a control diet (CON) without added lipids. Sea cucumber survival was not significantly different among dietary treatments (P>0.05). The highest weight gain was observed in sea cucumber fed the SLO diet, whereas the weight gain of sea cucumber fed the SO diet was the lowest among dietary treatments (P<0.05). No significant differences were found in the moisture, crude protein, crude lipid, and ash contents of whole sea cucumber body among dietary treatments (P>0.05). Concentrations of 20:5n-3 and 22:6n-3 were significantly higher in sea cucumber fed the SLO diet than in those fed on the other diets. The highest 18:2n-6 and 18:3n-3 contents were observed in sea cucumber fed the SO and LO diets, respectively. The results of this study suggest that squid liver oil could be used as a good lipid source in formulated diets for juvenile sea cucumber.
