Antarctic krill (Euphausia superba) is typical of a enormous biomass of marine zooplankton that could provide good nutrition in human body. This study was conducted to identify the nutrition of krill, a live in Antarctic Ocean. The analysis result of fatty acids of krill meal was as follow. The compositions of fatty acid were saturated fatty (SFA) acid 41.41%, monounsaturated fatty acid (MUFA) 21.69%, polyunsaturated fatty acid (PUFA) 36.89%, and p/s ratio was 0.89. The major fatty acids in all parts were eicosapentaenoic acid (EPA, 21.54%), palmitic acid (27.51%), oleic acid (13.35%) and docosahexaenoic acid (DHA, 12.42%). Especially, EPA and DHA were occupied 33.96% of polyunsaturated fatty acid. The mineral contents of krill meal were calcium 24477.21 mg $kg^{-1}$, sodium 14728.69 mg $kg^{-1}$, magnesium 6973.49 mg $kg^{-1}$, potassium 3981.67 mg $kg^{-1}$, iron 395.33 mg $kg^{-1}$ and manganese 5.74 mg $kg^{-1}$. The contents of major vitamin were retinol 86717.37 ${\mu}g$ RE, ${\beta}$-carotene 44.87 ${\mu}g$ RE, tocopherol 2.60 mg, pantothenic acid 1.61 mg, indicating that krill meal contains large amount of retinol and ${\beta}$-carotene.

This study was designed to compare content and composition of fatty acid in egg yolk oil among general eggs from chicken, quail, duck. We also compared those of general and functional chicken egg. Fatty acids were determined by GC method and the results were as follows: Palmitic acid, palmitoleic acid, stearic acid, oleic acid, linoleic acid, linolenic acid and timnodonic acid were identified in egg of chicken, quail and duck. The major fatty acid was oleic acid and palmitic acid in three kinds of eggs. Arachidonic acid and docosahexaenoic acid (DHA) were analyzed in egg of quail , but no in chicken. Monounsaturaterd fatty acid (MUFA) was higher in egg yolk oil of chicken and quail. Polyunsaturated fatty acid (PUFA) was higher in duck egg. Ginseng egg had significantly higher palmitic acid and oleic acid lower than general chicken egg. Gamgoal egg had lower palmitic acid and oleic acid, and higher palmitoleic acid and stearic acid than general chiekcn egg. The content of oleic acid was lower in DHA egg than in general chiecken egg, but arachidonic acid was detected only in DHA egg. Ginseng egg had the highest content of saturated fatty acid among chicken eggs. The content of MUFA acid was the highest in gamgoal egg and general chicken egg. DHA egg had the most amount of PUFA among all chicken egg.

The seeds of 16 domestic plants were studied for their moisture, total lipids and fatty acid composition. Of the 16 seeds, chestnut, corn, mungbean and ginko nut yielded less than 9% by weight of total lipids compared to others that gave 20-73%. The identified fatty acids from the seed lipids ranged from lauric acid (12:0) to lignoceric acid(24:0). It was intended in this study to classify the seed lipids according to their major fatty acids: Group t-Oleic acid; Group 2-0leic acid and linoleic acid; Group 3-linoleic acid; Group 4-linolenic acid ; Group 5-erucic acid ; Group 6-ricinoleic acid. The saturated fatty acid content of mungbean (33%) was the highest among the seed lipids studied. The highest value for the P/S fatty acid ratio(10) was in perilla.

This study was conducted to evaluate the quality characteristics of domestic as well as imported fermented skate. Three types of fermented skate products were analyzed for proximate composition, pH, VBN, ammonia-N, free amino acids, and fatty acids. The results indicated that the domestic fermented skate contained large amounts of TMAO. Also, the domestic and imported fermented skates each contained approximately 7.1 log CFU/g and $5.8{\sim}6.5$ log CFU/g of aerobic bacteria, respectively, and 585.9 mg and $384.1{\sim}398.5$ mg of total free amino acids, respectively; all samples contained high levels of taurine, anserine, lysine, alanine, glycine, proline, and ${\beta}-alanine$. For fatty acid composition, the domestic fermented skate contained 11 different types of saturated fatty acid and 16 types of unsaturated fatty acid, whereas the imported skate contained 8 types of saturated fatty acid and $10{\sim}15$ types of unsaturated fatty acid. Overall, the results suggest that domestic fermented skate is a better source of amino acids and essential fatty acids and contains more aerobic bacteria than imported fermented skate.

Chlorella 엽록체에서 인지질 생합성과 그의 지방산 조성에 미치는 amphotericin B($150\;\mu\textrm{g}/ml$)와 cycloheximide($10\;\mu\textrm{g}/ml$)의 영향을 분석하였다. Total lipid와 인지질 함량(PC, PE, PI)은 항생제 처리구가 대조구에 비하여 낮았다. Whole cell system에서의 주요 지방산은 대조구에서는 palmitic acid(31.96%)와 linoleic acid(16.96%)로 나타났으나 amphotericin B 처리구에서는 palmitic acid(36.15%)와 linolenic acid(16.71%)로 분석되었다. 또한 cycloheximide 처리구에서는 palmitic acid(31.90%)와 stearic acid(15.32%)가 인지질 형성에 이용되었다. 분리한 엽록체의 대조구(33.75%, 18.90)와 amphotericin B 처리(36.75%, 9.46%)에서 분리한 엽록체에서 인지질 형성에 이용되는 주요 지방산은 palmitic acid와 linolenic aicd였으나 cycloheximide 처리구에서는 palmitic acid(28.01%)와 oleic acid(19.27%)가 인지질생합성에 도입된 것으로 분석되었다.

In this research, fatty acid composition and trans fatty acids of 22 selected meat products produced by Turkish companies were analyzed by capillary gas liquid chromatography (GLC). Total fat contents of the meat products ranged from 11.60-42.50%. Salami had the lowest fat content 11.60% and sucuk (soudjuk) the highest 42.50%. Major fatty acids were C$_{16:0}$, C$_{18:0}$, trans C$_{18:1}$, cis C$_{18:1}$, and C$_{18:2}$ in the samples. Total unsaturated fatty acid contents have changed from 38.73 to 70.71% of total fatty acids, and sausage had the highest percentage among the samples. The majority of samples contain trans fatty acids and the level ranged from 2.28 to 7.95% of the total fatty acids. The highest amount of total trans fatty acids was determined in kavurma (Cavurmas) (7.95%), and total trans fatty acids of meat products such as pastrami contained more than 5% of the total fatty acids.

Fifteen free fatty acids including myristic acid were isolated and identified from red ginseng processed from CA and MA stored fresh ginseng. Linoleic acid (80%) and palmitic acid (10.5%) content were the major components accounting for more than 90% of the total free fatty acid. The contents of free and identified fatty acids were not greatly changed in all the treatments. Especially when preservative was treated, the change of free fatty acid was quite stable over the control. Each fraction of neutral, glyco- and phospholipid was constant in terms of quantities before and after the treatment. Key words Controlled atmosphere, modified atmosphere, fresh ginseng, red ginseng, fatty acid.

After the glycolipid(GL) and phospolipid (PL) of flint corn during a growth process were fractionated by silicic acid column chromatography (SACC), the GL and PL of polar lipids were separated by thin layer chromatography (TLC)and quantitative by TLC scanner and the fatty acid composition in polar lipids were determined by gas chromatography (GC). Of the GL in polar lipids were separated by TLC, monoglycosyl diacylglycerol (8.3~29.2%) was the major component, and monoglycosyl ceramide, monoglycosyl sterol were also found as minor components. Of the PL, phosphatidyl choline (27.2~29.5%) and phosphatidyl inositol (42.9~79.1%) were the major components, and phosphatidyl ethanolamine and cardiolipin were also persont in the PL. The major fatty acids in the GL were oleic(27.1~37.1%), linoleic (13.2~35.7%) and palmitic (22.5~25.6%) acids. The major fatty acids in the PL were palmitic (46.5~52.3%), heptadecanoic (23.0~25.1%) and oleic(7.2~14.6%) and GL contained a higher percentage of unsa-turated fatty acids, but PL presented that of the saturated fatty acids.
