  • To measure the mineral content of fishes, we collected 177 individuals from 53 fish species from the east (Pohang), west (Gunsan), and south (Tongyeong) coasts of Korea. The mean content of the macro mineral in a 100 g sample taken from the edible portion of each fish was (in descending order): P(207.4 mg), K(169.7 mg), Na(101.6 mg), Ca(44.4 mg), and Mg(30.4 mg). In comparison, the mean content of micro mineral in the fishes was (in descending order): Zn ($8.98{\mu}g/g$), Fe ($5.03{\mu}g/g$), Cu ($0.76{\mu}g/g$), Mn ($0.43{\mu}g/g$), and Ni ($0.08{\mu}g/g$). We could not observe clear regional variation in the mineral content of fish species. With regard to minerals considered essential for humans, the amount of Ca per sample (100 g) was the highest in the Scyliorhinus torazame (465.4 mg), and than followed by Ammodytes personatus (338.0 mg), Dasyatis akajei (267.4 mg), Raja kenojei (248.1 mg), Conger myriaster (174.1 mg), Clupanodon punctatus (86.8 mg), Muraenesox cinereus (81.2 mg), and Engraulis japonica (70.4 mg). The daily average intake of the mineral through the fishes consisted of P (100.6 mg), K (82.3 mg), Na (49.3 mg), Mg (14.8 mg), Zn (0.44 mg), Fe (0.24 mg), Cu (0.04 mg) and Mn (0.02 mg). The respective intakes of macro mineral (P, Mg, Na, Ca, K) from the fishes were about 14.4, 4.2, 3.3, 3.1 and 1.8% of the dietary reference intakes for Koreans (KDRIs) set by the Korean Nutrition Society. In comparison, the respective intakes of micro mineral (Cu, Zn, Fe, Mn) from the fishes were about 4.6, 4.4, 2.4, and 0.6% of the KDRIs.

  • This study was conducted to prepare basic materials and offer advice regarding dietary habits to prevent and cure childhood obesity by comparing and analyzing dietary habit, nutritional status, blood factors, and mineral contents of hair. All subjects were stratified by their weight-length index (WLI). According to the standard WLI values, 64.9% of children were within the normal value, 13.5% of children were underweight, and 21.6% of children were overweight and obese (WLI ${\geq}$ 110%). Overall, the score assessed dietary habit for all children was $21.32{\pm}2.55$ point (921 subjects), with 5.1% of children having excellent dietary habits and 3.1% having poor dietary habits. Additionally, 37.9% of underweight children, 37.6% of normal weight children, and 43.2% of overweight and obese children consumed higher amounts of protein than underweight children did (meat, fish, eggs, and soy products) (P < 0.05). Overweight and obese children consumed more fried foods than underweight or normal weight children (P < 0.05). Moreover, 38.0% of the children had hemoglobin levels of 12 g/dl, while 7.6% were anemic (11.1 g/dl). When a hematocrit level of 33% was taken as the standard, 11.0% of children were anemic. The plasma transferrin content was $263.76{\pm}54.52$ mg/dl in overweight and obese children. The mean values of Fe, Cu, Ca, Cr, Mn, Se, Na, K, Li, V, Co, and Mo were within the reference values, but the Zn concentrations of underweight, normal weight, and overweight and obese children were $67.97{\pm}28.51$ ppm, $70.09{\pm}30.81$ ppm, and $73.99{\pm}30.36$ ppm, respectively. The Zn concentration of overweight and obese children ($73.99{\pm}30.36$ ppm) was lower than that of the standard value (180~220 ppm). Therefore, a nutritional education program and new guidance for dietary pattern should be developed to reduce the number of underweight and overweight and obese children.

  • The effect of dietary Antartic krill(Euphausia Superba) meal on the performance of broiler chicks during the acute phase responses was studied. One d-old male broiler chicks(Avian) were fed on the experimental basal (0.0 % krill meal), and 0.5 and 1.0 % krill meal diets, and then the acute phase response were activated by injecting Salmonella typhymurium lipopolisaccharide(LPS) three times i. p. at 8, 10 and 12 day of age. The 1.0% krill meal diet group had reduced daily gain and feed efficiency during the acute phase response of the 2nd week of age, while during recovery from the acute phase response of the 3rd week of age the lowered performance disappeared. The acute phase response increased the relative weight of liver and spleen, and dietary krill meal enhanced the activities of MnSOD and Cu/ZnSOD in liver and erythrocyte cytosols during the acute phase response, although neither the acute phase response or dietary krill meal affected significantly PHA-p hypersensitivity. The results indicated that dietary krill meal affected the performance and SOD activity of broilers chicks during the acute phase response.

  • In the present study, we investigated the compositions, antioxidant activities and anti-tumor effects of Artemisia princeps Pampanini (APD) as well as blanched leaves (CNBD) and dried leaves (CND) from Cirsium setidens Nakai on HepG2 cells. Water and ash contents were increased in CND. Protein and lipid contents were increased in CNBD. K, Ca, Mg, Fe and Cu contents of CND were higher than those of CNDB and APD. P contents was significantly decreased in CND. Yields of CND was reached high levels, but TPC, TFC, acacetin, apigenin, cynarin contents, and antioxidant activity were higher in APD. Viability of HepG2 liver cells was significantly decreased in APD. Therefore, extracts of APD are more effective preventing the liver cancer than extracts of CND and CNBD.

  • This study was conducted to develop pigment of flowers as a food material and the red rose(Rosa hybrida L.) was used for this study. To check the possibility of using the rose pigment as a food additive we have extracted the pigment from rose and examined all the factors (pH, temperature, free sugars, organic acids, metal ions) for stability. The results obtained are as follows: In examining the stability of the pigment, the residue of the pigment noticeably decreased with the increase of the pH and the temperature, and among free sugars (fructose, glucose, sucrose) the addition of fructose made the residue the lowest. With the addition of organic acids the samples exhibited the hyperchromic effect throughout the period of the storage. The pigment residue decreased when the amount of the metal ions increased and especially the Cu$^{2+}$ ion was most destructive.

  • In order to obtain the basic data fer the processing adaptability of Korean figs(Ficus carica L.), physicochemical analyses were carried out with Korean common type figs in the different ripening stages. Moisture contents decreased, but the contents of protein, fat carbohydrate and soluble solids increased according to the ripening of fruits. K was detected as the most abundant one of all the minerals and Ca, Mg, Na, Fe, Mn, Zn and Cu were the next in order. The mineral contents decreased slightly with ripening. Especially, Ca, Mg, U, Fe and Zn were higher in the unripened H stage figs. The antioxidative activity was assayed with water and methanol extracts from ripened figs by the DPPH radical scavenging ability. The antioxidative activities of Korean figs were relatively high and increased in a dose dependent manner. The methanol extract showed the higher antioxidative activity than the water one. Therefore, the methanol was the better solvent than water for the antioxidative compounds. These results suggested that Korean figs are relatively the good sources of minerals, especially the Ca and the antioxidative compounds.

  • This study was carried out to evaluate effects of either organic or inorganic sources of both chromium and copper on growth performances, nutrients digestibility and fecal Cr, Cu, and Zn excretion in growing pigs. A total of 36 growing pigs((Landrace×Yorkshire)×Duroc, weighing 61.2kg in average) were allotted to 4 treatments with 3 replicates and 3 pigs per replicate. Four treatments were designated by supplemental sources of both chromium and copper as follows: ①200ppb Cr as Cr-methionine chelate(CrMet) and 200ppm Cuas copper methionine chelate(CuMet), ②200ppb Cr as CrMet and 200ppm Cu as copper sulfate(CuSO4), ③200ppb Cr as chromium chloride(CrCl3) and 200ppm Cu as CuMet, ④200ppb Cr as CrCl3 and 200ppm Cu as CuSO4. Growth performance was highest(p<0.05) in CrMet and CuMet supplemented diet treatment. Nutrients digestibility of diets was lowest(p<0.05) in CrMet and CuSO4 supplemented diet treatment, and highest(p<0.05) in CrMet and CuMet supplemented diet treatment. Fecal copper, zinc and chromium excretion was highest(p<0.05) in CrCl3 and CuSO4 supplementation treatment and lowest(p<0.05) in CrMet and CuMet supplementation treatment. This study showed a relatively high degree of utilization of Cr and Cu as well as Zn by supplementation of CrMet and CuMet compared with those of the inorganic sources.
