  • Proximate compositions and fatty acid profiles of cultured and wild mackerel (Scomber japonicus) muscles were compared. Protein content ranged from approximately 16% to 18% and was higher in wild fish than in cultured ones. Lipid content was between two to four times higher in large and small cultured fish (20.1-20.5%) compared with same sized wild fish. The prominent non-polar lipid (NL) class in fish muscles was triglyceride, and additionally, free sterol was among the prominent NL classes in wild fish muscles. Prominent phospholipid (PL) classes in cultured and wild fish muscles were phosphatidylethanolamine and phosphatidylcholine, with the former being higher in cultured fish and the latter higher in wild fish. Prominent fatty acids of total lipid were 16:0, 18:1n-9, 22:6n-3 (docosahexaenoic acid, DHA), 20:5n-3 (eicosapentaenoic acid, EPA), 16:1n-7, 18:0 and 14:0, while 18:2n-6 was among the prominent fatty acids in cultured fish. The n-3 polyunsaturated fatty acids (PUFA, DHA+EPA) content (in mg/100 g of muscle tissue) was higher in cultured fish (2,711 mg in large fish and 2,572 mg in small fish) than in wild fish (2,431 mg in large fish and 1,398 mg in small fish). In conclusion, we have been able to demonstrate that cultured mackerel could also be a good sources of n-3 PUFA, such as DHA and EPA.

  • Proximate and fatty acid compositions in muscle tissue were studied in 14 species of coastal and offshore fishes in Korea. Lipid content ranged from 0.57 to 10.5% and was higher in migratory and reef dwelling fishes than in demersal fishes. Protein content ranged from 14.4 to 20.3% and moisture content ranged from 72.4 to 81.8% in all fish samples. There was a negative correlation between lipid and moisture content in all fish samples (r= -0.90, P<0.001). The prominent fatty acids were 16:0, 22:6n-3 (docosahexaenoic acid, DHA), 18:1n-9, 20:5n-3 (eicosapentaenoic acid, EPA), 16:1n-7, 18:0 and 18:1n-7. Most demersal fishes contained considerably higher amounts of 20:4n-6 and/or 22:5n-3 compared with migratory and reef dwelling fishes. The proportion of total polyunsaturated fatty acid (PUFA), including DHA and EPA, was higher in demersal fishes (38.6-54.0%) than in migratory and reef dwelling fishes (23.5-35.2%).

  • Objective: The aim of this study was to investigate the effects of simultaneous supplementation of laying hens with alpha-linolenic acid (ALA) resources (flax, perilla, and Eucommia ulmoides [E. ulmoides] seeds) and eicosapentaenoic acid/docosahexaenoic acid (EPA/DHA) resources (Schizochytrium sp.) on egg quality and n-3 polyunsaturated fatty acids (PUFA) profile. Methods: Dietary treatments were as follows: i) diet C (control diet); ii) diet F (diet C+10% flaxseeds); iii) diet P, (diet C+10% perilla seeds); iv) diet E (diet C+10% E. ulmoides seeds); v) diet A (diet C+1.5% microalage); vi) diet AF (diet C+10% flaxseeds+1.5% microalage); vii) diet AP (diet C+10% perilla seeds+1.5% microalgae); viii) diet AE (diet C+10% E. ulmoides seeds+ 1.5% microalage). Results: Egg weight, yolk weight and production ratio were not significantly affected by either algae or in combination with seeds (p>0.05). No significant difference was observed in ALA and DHA concentration in eggs between flaxseed, perila, and E. ulmodies seeds supplementation alone (p>0.05). N-3 PUFA in eggs was slightly improved by microalgae supplementation. The best supplementation, a combination of microalgae and perilla seeds, elevated (p<0.05) ALA from 19.7 to 202.5 mg/egg and EPA+DHA from 27.5 to 159.7 mg/egg. Highest n-3 PUFA enrichment (379.6 mg/yolk) was observed with supplementation of a combination of perilla seed and microalgae (362.2 mg/yolk), followed by a combination of flaxseed and microalgae (348.4 mg/yolk). The ALA, EPA, and DHA content obtained with a combination of microalgae and seeds surpassed the total sum of that obtained with microalgae or ALA-seeds alone. Conclusion: It is feasible to enrich eggs with n-3 PUFAs by perilla or E. ulmodies seeds instead of flaxseeds. Simultaneous supplementation of microalgae and seeds helped improve the transfer from EPA and docosapentaenoic acid into DHA.

  • BACKGROUND/OBJECTIVES: We examined dietary fat intake and the major food sources by young children in Korea. SUBJECTS/METHODS: A total of 1,041 children aged 1-5 years were identified from the 2013-2015 Korea National Health and Nutrition Examination Survey. Data on total fat and fatty acid intake were obtained by a single 24-h dietary recall. Food sources were identified based on the amounts of total fat and fatty acids consumption according to each food. Fat and fatty acid intakes and their food sources were presented by age group (1-2-y, n = 401; 3-5-y, n = 640). Fat and fatty acid intakes were also evaluated according to socioeconomic characteristics. RESULTS: The mean intake of fat was $27.1{\pm}0.8g$ in the 1-2-y group and $35.5{\pm}0.7g$ in the 3-5-y group, and about 23% of the total energy was obtained from fat in both age groups. The mean intake of saturated fatty acids (SFA) was $10.5{\pm}0.3g$ in the 1-2-y group and $12.7{\pm}0.3g$ in the 3-5-y group, with the 1-2-y group obtaining more energy from SFA than the 3-5-y group (9.2% vs. 8.3%). The mean intake of polyunsaturated fatty acids (PUFA) was $6.3{\pm}0.1g$ in the total subjects, with $0.8{\pm}0.03g$ of n-3 fatty acids and $5.5{\pm}0.1g$ of n-6 fatty acids being consumed. Milk, pork, and eggs were major food sources of total fat, SFA, and monounsaturated fatty acids, and soybean oil was the main contributor to PUFA in both age groups. In the 1-2-y group, children in rural areas had significantly higher intake of PUFA and n-3 fatty acids than did those in urban areas. CONCLUSIONS: Our findings provide current information on dietary fat intake among young Korean children and could be used to establish dietary strategies for improvement of health status.

  • 통영을 중심으로 한 우럭생산량은 연간 1,813M/T에 이르고 있으며, 과잉생산에 대한 우려가 제기되고 있다. 이와 같은 우려를 개선시키고 기능성 어류에 대한 소비자의 기대감을 충족시키기 위하언 성장촉진, 항암, 면역증강, 혈중 LDL 함량 저하효과를 가진 것으로 알려져 있는 CLA를 이용한 기능성 우럭생산의 가능성을 검토하였다. Artemia 영양강화시 CLA를 $0.5\~5.0\%$ 첨가하였을 경우 Artemia중 지방산조성의 변화를 조사한 결과 CLA 첨가량이 증가할수록 CLA 함량은 높아졌고, 동시에 Artemia 특유의 지방산조성을 나타내어 지방산 대사에 특별한 영향을 미치지지는 않는 것으로 나타났다. 8주 사육 후 우럭근육 중 n-6지방산의 함량이 높아 사료에 첨가된 지질의 영향을 받은 것으로 나타났다. 그리고 n-3/n-6 PUFA 비가 자연산 우럭의 3.95보다 현저히 낮아 CLA 첨가가 많을수록 성장을 저해하는 것으로 나타나 배합사료 중의 DHA 첨가가 증가되어야 할 것으로 여겨진다. 그러나 이를 섭취한 우럭 근육 중 총 CLA 함량은 급이 량에 따라 각각 $6.57\~16.07\%$가 축적되어 CLA는 다른 지질성분과 함께 어체내 대사과정을 거치는 것으로 나타났다. 우럭의 성장도, 사료효율, DHA/EPA 비, n-3/n-6 PUFA 비, 활력테스트, 혈액지수 둥을 비교하였을 때 $1.0\%$ CLA 첨가가 적절한 첨가량인 것으로 생각된다.

  • In this study, the nutritional and storage quality of meatballs formulated with different levels (0, 1.5, 3.0, 4.5 and 6.0%) of bee pollen were investigated during storage at $41^{\circ}C$ for 9 d. Protein content of meatballs increased, while moisture content decreased with increased pollen. The addition of pollen improved cooking loss but decreased the redness (Hunter a value) and sensory scores. Textural parameters (hardness, springsness, gumminess, and chewiness) were affected by pollen addition and the hardness and gumminess values of meatballs decreased as the pollen content increased. While C18:0 content of meatballs slightly decreased with pollen addition, C18:2n-6c, C18:3n-3, C20:5n-3, and PUFA contents increased. The PUFA/saturated fatty acids (P/S) ratio increased from 0.05 in the control to 0.09 in meatballs with 6.0% pollen. The n-6/n-3 ratio decreased from 11.84 in the control to 3.65 in the meatballs with 6.0% pollen. The addition of pollen retarded the lipid oxidation and inhibited the bacterial growth in meatballs. The pH, redness, TBA value and total aerobic mesophilic bacteria, coliform bacteria and S. aureus counts values changed significantly during storage. The results suggest that bee pollen could be added to enhance the nutritional and storage quality of meatballs with minimal changes in composition and/or sensory properties.

  • The strategy for increasing the palatability of Hanwoo beef through fattening could lead to a decline in yield grade. The aim of this study was to examine the meat quality traits of Longissimus dorsi (LD) muscle from carcasses of Hanwoo steers at different yield grades. A total of 246 Hanwoo steers was divided into the following yield grades: A (n=77), B (n=76) and C (n=93). Meat quality traits, including proximate composition, cholesterol content, nucleotide content, dipeptide content, creatine and creatinine, free amino acid content, fatty acid composition, instrumental meat color, pH, water holding capacity, drip loss, cooking loss, and sensory qualities of the LD muscle from the 3 yield grades of Hanwoo carcasses were measured. The decline in yield grade from A to C resulted in an increase in crude fat and cholesterol content as well as a decrease in inosine 5'-monophosphate and aspartic acid in the LD muscle (p<0.05). In terms of fatty acid composition, the LD muscle from yield grade A had higher SFA and PUFA and lower MUFA content than that from yield grade C (p<0.05). However, the ratio of PUFA/SFA and n-6/n-3 did not differ among LD muscles from the 3 yield grades. There were no significant differences among other meat quality traits in relation to the yield grade. In conclusion, we suggest that the changes of substances related with health and flavor can be considered in order to obtain better quality Hanwoo beef.

  • To investigate the association between intake of freshwater fish and their fatty acids and the risk of breast cancer in Chinese women, we conducted a case-control study with 669 cases and 682 population-based controls in Jiangsu Province of China. A structured questionnaire was used to elicit detailed information. Unconditional logistic regression analysis was performed to calculate odds ratios (ORs) and 95% confidence intervals (CIs). Total freshwater fish intake was linked to decrease in the adjusted OR for breast cancer, but without dose-dependence. Analyses by freshwater fish species showed that consumption of black carp and silver carp was inversely related to breast cancer risk, with adjusted-ORs for the highest intake category of black carp (${\geq}500g/month$) of 0.54 (95%CI=0.33-0.92; $P_{trend}$ <0.002) and for silver carp (${\geq}1000g/month$) of 0.19 (95%CI=0.11-0.33; $P_{trend}$ <0.001). In contrast, consumption of crucian carp was positively related to breast cancer risk, with an adjusted OR for the highest intake category (${\geq}1000g/month$) of 6.09 (95%CI=3.04-12.2; $P_{trend}$ <0.001). Moderate intakes of SFA, PUFA, n3-PUFA and n6-PUFA from freshwater fish may decrease the risk of breast cancer among premenopausal women. The findings of this study suggest that intake of freshwater fish and their fatty acids may modify risk of breast cancer, and that different species of freshwater fish could have a different actions on breast cancer risk. Future epidemiologic studies are needed to know the effects of freshwater fish intake on breast cancer risk and the cause of these effects.
