  • To confirm basic nutrient contents of Korean honey as a food material, we assessed New Zealand Manuka honey by measuring proximate components, vitamin C and minerals of 16 kinds of honey harvested in South Korea. The proximate composition of each honey sample was as follows: moisture content 18.45~29.84%, crude protein 0.10~0.95% (vs Manuka honey 0.23%), crude fat 0.02~0.60% (vs Manuka honey 0.34%), crude ash 0.01~.52% (vs Manuka honey 0.24%) and carbohydrate 67.90~80.94% (vs Manuka honey 79.39%), respectively. In the case of free sugars analyze by HPLC, fructose showed a content of 26.12~49.84% which was highest in acacia honey and lowest in sorbus honey. Content of glucose was 19.38~36.12% and lowest in chestnut honey, whereas sucrose, lactose, maltose were absent. Total sugar contents were 64.16% which was less than Manuka honey (70.23%) and vitamin C was not detected in all samples. Minerals were detected 15~25 kinds, including K, Ca, Mg, Zn, Fe, Cu, Mo and so on. Ca was high in order of linden > canola > codonopsis > hedysarum honey, and K was higher than in Manuka honey in order of chestnut > hedysarum > codonopsis > jujube honey. Especially, these results suggest that Korean honey have a better nutrient content profile than Manuka honey.

  • This study was conducted to compare the growth, inorganic components, and proximate components of Codonopsis lanceolata grown in 10 regions of Korea for selecting superior species and breeding by crossing. Among the all tested lines, the shortest plant height (217.12 cm) was observed from the Ulleungdo region line (No. 4) while the longest (273.9 cm) was observed from Hwasun region line (No. 9). In addition, the lines of central and northern region (No. 1~No. 7) tend to have shorter plant height than those of southern region (No. 8~No. 9) except Jejudo region line (No. 10). Flowering tends to be late towards southern region, and lines in central and northern regions were started flowering about 2 weeks earlier than those in southern regions. However, the heaviest root weight was 13.1 g, found in only Jejudo line (No. 10) whereas there was no significant difference found in the other regions which have a range of 8.3~11.0 g. The inorganic components were varied in each line, however, proportion of macroelements, such as K, Ca, and P, was the largest for every line. Especially for Heongseong region line (No. 2), had larger proportion of macroelements than the others. There was a difference of proximate compositions of Codonopsis lanceolata, except the moisture content, among all regions, however, it was generally shown that the content of crude protein (1.31~3.76%) and crude fiber (2.18~3.12%) was the highest.

  • Yam(Dioscorea) tubers were used as one of the dietary starches in Korea, China and Japan because of its characteristic properties. Yam tubers were powdered after freeze drying the sliced tubers to investigate carbohydrates. Chemical properties such as proximate components and carbohydrates were studied using three varieties of Korean yams, namely. D. batatas, D. aimadoimo and D. japonica. The proximate components of yam tubers showed that the major components of Korean yam tubers were carbohydrates and moisture. The main components of free sugars in yams were identified as fructose, glucose, sucrose and maltose. In addition to these four sugars, there were two unidentifiable peaks whose areas are too big to ignore. These results were obviously different from other reported data of free sugars in yams. The main components of total sugars were mannose and glucose.

  • The proximate, fatty acid and total amino acid compositions of striped jewfish Stereolepis doederleini muscle were studied. The proximate composition was: 76.4% moisture, 19.4% protein, 2.92% lipid, and 1.19% ash. The predominant total lipid fatty acids were 16:0 (18.7%), 18:1n-9 (16.5%), 22:6n-3 (16.0%), 16:1n-7 (8.53%), 20:5n-3 (7.97%) and 18:0 (5.34%). Glutamic acid (17.4%), lysine (10.6%), aspartic acid (10.4%) and leucine (8.27%) were the predominant amino acids in striped jewfish muscle. These food components of striped jewfish were similar to those of costal and reef dwelling fishes such as black rockfish, black sea bream and rock trout, which are common sliced raw fish in Korea. Therefore, these results suggest that striped jewfish may represent a new aquaculture fish species.

  • This study was carried out in order to utilize ginseng marc (GM), a byproduct produced during the preparation of ginseng extract. For the utilization of GM as coffee-replacing beverage, GM was roasted at 140-23$0^{\circ}C$, for 10-30 min to generate coffee-like flavor and taste. The physicochemical changes in GM induced by roasting process was measured. Weight and moisture contents of GM abruptly decreased while roasting at various temperature and period of time, and the amount of water-extracted solid substances decorated beyond 23$0^{\circ}C$. Among the proximate components, total and free sugar decreased remarkably, while crude fat content increased. Crude protein content did not change by the roasting process. pH derides to pH 4.9 after 30 min at 20$0^{\circ}C$, but increased at higher temperatures. Hunter color L value of the GM powder decreased, whereas a and b values, increased up to 10 times as compared to that of the control. The brown color(O, D 490 nm) in 50% ethanol extract of the roasted GM was 46 times higher than that of the control.

  • To utilize the leaves of broccoli, the shape of which was similar with that of kale leaves, as a vegetable juice, the extracts from two types of vegetable leaves were subjected to the analyses of proximate com ponents, volatile sulfur compounds, vitamin C and minerals. The sensory evaluation of the juices, prepared from kale and broccoli leaves, were performed by duo trio test and scoring test. Among eight varieties of broccoli, four varieties('Pilgrim', 'Greenbelt', 'Salinas' and 'Shasta')were not significantly different from kale(p<0.05), based on the duo trio sensory test. Sulfur and nitrogen compounds present in the dichloromethane extracts of kale and broccoli leaves 'Pilgrim' were identified as 3 butenyl, allyl, butyl and 4 methylsulfinylbutyl isothiocyanate(sulforaphane), 4,5 epithiovalero, 4,5 epithio 3 hydroxyvalero, benzenepropane, 3 hydroxy 4 propene, 4 methylthio butane, 3 hydroxy 3 phenylpropane, 5 methy lsulfinylpentane, 4 methoxyphenyl 3 hydroxypropane nitrile and dimethyl trisulfide by GC/MSD analysis. Proximate components were observed to be relatively similar between kale and broccoli leaves. Vitamin C and sugar content were higher in broccoli leaves(125∼180mg% and 8∼12°Brix) than in kale(101mg% and 7oBrix). In mineral analysis by AA and ICP Mass, 'Pilgrim' showed a higher content of K, Fe, Mn, Zn and Se. In separate experiment, sensory scores of bitter taste and astringent taste were lower and scores of over all taste and over all acceptability, higher in broccoli('1243') juice than those in kale juice.

  • Proximate analysis, mineral and fatty acid composition of three conventional domestic soybean cultivars and two imported ones including glyphosate-tolerant HS2906 were evaluated by AOAC method, ICP-AES and gas chromatography. There were several differences in the proximate analysis among three conventional domestic soybean cultivars ; higher crude fat in the cultivar Hwanggumkong, higher crude protein in Pungsankong, and higher carbohydrate and crude ash in Duyukong. The ranges of contents of proximate components of domestic cultivars were similar to the data previously reported. There were no significant differences in proximate analysis between conventional soybean WS82 and glyphosate-tolerant HS2906 ; 23.55-23.90% of crude fat, 34.22-35.55% of crude protein, 6.25-6.45% of crude ash, and 25.35-26.47% of carbohydrate. The mineral and fatty acid compositions of HS2906 were similar to those of conventional soybeans previously reported.

  • In order to evaluate the nutritive value of the forage plants in South Sulawesi, Indonesia, 266 samples (61 grasses and 65 legumes grown in the dry season, 60 grasses and 80 legumes grown in the rainy season) were collected from the highland and lowland in 1998 to 2000, and were subjected to the determination of chemical composition and digestibility. The least-squares analysis of variance demonstrated that the in vitro dry matter digestibility (IVDMD) of grasses was not significantly affected by season or altitude. On the other hand, the some proximate components and cell wall components were significantly affected by season and altitude including the season${\times}$altitude interaction. For the legumes, the in vitro neutral detergent fiber digestibility (IVNDFD) and cellulose content were significantly affected by season. On the other hand, the ether extract (EE) content was significantly affected by season and altitude. The interaction of the season${\times}$altitude for IVDMD, of the year${\times}$season for some proximate components and of the year${\times}$season and the season${\times}$altitude for some cell wall components were significant. These results indicate that the forages grown at highland in dry season have a relatively high quality. The means of the total digestible nutrient (TDN) content estimated from IVDMD in grasses and in legumes were 50.3% and 57.4%, respectively, and the crude protein contents were 7.7% and 17.6%, respectively. The correlation coefficients between IVDMD and the contents of crude fiber, neutral detergent fiber and acid detergent fiber were relatively high in all of forage plants, suggesting that these components would provide an accurate prediction of digestibility or TDN content. A close relationship between IVNDFD and lignin content indicates that the lignin would be the most accurate predictor of cell wall digestibility.
