  • The study was conducted to determine physicochemical parameters in various physical fractions (linter, hull, kernel, oil and meal) of cottonseed of different varieties (MNH 147, CIM 240, NIAB 78, FH 87, CIM 109, MNH 93, FH 682, GOHAR 87, SLS 1 and B 557). Average components of linter, hull, and kernel in different varieties of cotton were 12.21, 28.24 and 70.42%, respectively. Average percentage of meal and oil was 48.97 and 22.09% in seed, and 69.28 and 30.72% in kernel, respectively. Maximum percentage of meal was recovered from variety CIM 240 and lowest in variety CIM 109. Statistical analysls revealed variety differences (p<0.05) in seed and it's components. Average contents of crude protein, crude fiber and ash was 22.31, 17.74 and 4.27% in seed, 2.85, 56.50 and 2.61% in hull; 32.62, 3.45 and 4.01 % in kernel; 47.15, 5.00 and 5.78% in meal, respectively. Average contents of Ca, p, Mg, K, Na and Cl were 0.09, 0.22, 0.26, 0.65, 0.009 and 0.035% in seed; 0.12, 0.07, 0.09, 0.51, 0.020 and 0.034% in hull and 0.16, 0.59, 0.32, 1.01, 0.03 and 0.07% in meal of different varieties of cotton, respectively. Fe, Zn, Cu and Mn were 141.35, 24.55, 186.50 and 27.12 mg/kg in seed; 158.48, 2.06, 74.60, and 22.17 mg/kg in hulls; and 167.62, 20.30, 185.83 and 20.67 mg/kg in meal, respectively. Significant varietal differences were observed in proximate composition and mineral contents of cottonseeds and derived products. Cottonseeds and their products of varieties FH 87, CIM 109 and MNH 93 showed higher nutrient density while lower was observed in varieties CIM 240, SLS I and FH 682.

  • Recently, relatively large amount of a new species of crab belonging to genus Chionoecetes that has intermediate characteristics between red-tanner crab (Chionoecetes japonicus) and queen crab (C. opilio) was caught the East Sea of Korea. The new species of crab was tentatively named Neodo-Daege. Amino acid and proximate compositions of the edible meat of red-tanner crab and Neodo-Daege were determine. The proximate composition of the meats of Neodo-Daege were $79.2{\%}$ in moisture, $17.4{\%}$ in protein, $0.6{\%}$ in lipid, and $1.5{\%}$ in ash. Neodo-Daege was higher in protein and lipid contents, and lower in moisture and ash contents than those of red-tanner crab. The total amino acid contents in the meat of Neodo-Daege were higher than those of red-tanner crab, but the profile of amino acids was similar to one another. Among amino acids, glutamic acid, arginine, aspartic acid, lysine and glycine were major components of the crabs.

  • The purpose of this study was to compare differences in the main food components between Korean and imported quinoa from Peru, the U.S., and Thailand. Proximate composition of Korean quinoa showed highest crude protein and crude ash, while Korean quinoa had lowest moisture. Total amino acid content was higher in Korean quinoa than in imported quinoa. Fatty acid content was highest in quinoa cultivated in the U.S. and Wonju. Quinoa cultivated in Wonju was rich in palmitic acid, lignoceric acid, linoleic acid, eicosadienoic acid, erucic acid, and nervonic acid. Mineral content was higher in Korean quinoa than in imported quinoa. Quinoa cultivated in Wonju showed highest contents of P, Mg, Zn, while quinoa cultivated in Hongcheon showed the highest content of Na. Citric acid was found the major organic acid in quinoa. Citric acid content was highest in quinoa imported from the U.S. and lowest in quinoa cultivated in Hongcheon. Among free sugar, raffinose and glucose contents were highest in quinoa cultivated in Hongcheon, The results of this study show Korean quinoa has high contents of protein, amino acids, fatty acids, minerals and free sugar, offering essential amino acids in an excellent balance.

  • Chemical components of Panax (P) species were compared. p. species used were Korean white ginseng, Korean, Chinese and Japanese red ginseng (P ginseng), American and Canadian ginseng (P. quinquefolium) , and sanchl ginseng (P. notoginseng). No significant difference in the proximate contents was observed among P. species. Ash, crude lipld and total sugar contents in root of P. notoginseng were found to be relatively lower than those of P. ginseng and P. quinquefolium, but the contents of crude protein and crude fiber were similar among those ginsengs. Mineral nutrient con tents showed a little difference among ginseng species. Total nitrogen contents were slightly higher in P. ginseng than P. quinquefolium and P. notoginseng and Fe and Cu were lower in Chinese and Japanese red ginsengs. Kinds and compositions of amino acids were similar but contents of amino acids were different among ginseng species. Total amino acid contents were 76.3∼83.9 mg/g in P. ginseng 53.8∼60.4 mg/g in p. quinquefolium and 54.9 mg/g in P notoginseng. Free sugar contents were lower in P. notoginseng than P. ginseng or P. quinquefolium. Sucrose accounted for 90∼92% of total free sugar contents with relatively high content in white ginsengs, while sucrose and maltose were 32-36% and 55∼60%, respectively, in red ginseng.

  • Proximate chemical components (protein, oil, carbohydrate, ash, fiber, and starch) were determined from tubers grown in upland and wetland conditions. The contents of crude protein, oil, carbohydrate, and starch were higher in upland condition than in wetland condition. Eight gibberellins were commonly identified and quantified in leaves and tuber of chufa grown in wetland and upland field during growing season. Gibberellin content was always higher specifically in the leaves and tubers grown in wetland condition than in those grown in upland condition. The current knowledge of gibberellin biosynthesis suggests that the two endogenous bio-active gibberellins both $GA_1$ and $GA_4$ are differently metabolized according to cultural conditions. Major gibberellin biosynthesis route is ascertained dominantly the non C-13 hydroxylation pathway leading $GA_4$ in chufa plants.

  • 계피추출액의 유효성분과 가용성물질의 용출량에 미치는 추출온도, 시간, 용매첨가량, 추출횟수 등의 영향을 조사하였다. 일반성분과 cinnamic acid, cinnamic aldehyde, eugenol 함량은 추출온도가 $20^{\circ}C$에서 $80^{\circ}C$로 높아짐에 따라 증가하였고 $100^{\circ}C$에서는 큰 변화가 없었다. $80^{\circ}C$에서 10시간 추출하는 동안 6시간 이상에서는 일반성분과 cinnamic acid, cinnamic aldehyde, eugenol 함량의 증가율이 낮았고 용매첨가량에 있어서는 계피중량의 $5{\sim}40$배 첨가구까지는 일반성분과 유효성분의 용출량이 증가하다가 그 이상의 용매첨가에 의해서는 완만한 증가를 보였으며 추출횟수는 $1{\sim}2$회로 하는 것이 이들 성분의 용출에 효율적이었다.

  • Sea-buckthorn fruits (Hippophae rhamnoides L.) are used in Mongolia as traditional medicine due to the health-benefits associated with its bioactive components. The purpose of this study was to investigate the chemical composition of Mongolian sea-buckthorn fruits. In terms of proximate composition, crude fat content was the highest, whereas its crude ash content was the lowest. In organic acid contents, malic acid content ($6.30{\pm}0.005$ mg/g) was the highest. Free sugars were composed of sucrose, xylose, glucose and mannitol. Vitamin C and carotenoid content were 320 mg/100 g and 715.25 mg/100 g, respectively. The major fatty acids were palmitic (C16:0), palmitoleic (C16:1), caprylic (C8:0) and linoleic (C18:2) acid.

  • The degree of maturity of rice greatly affects the quality of the rice, including factors such as the integrity of grains, color, and the nutritive components. Green Rice$^{(R)}$ is rice (Oryza sativa L.) that has been harvested earlier than brown rice and appears green in color. To determine suitable harvesting time of the Jinbu variety of Green Rice$^{(R)}$ in Gyeonggido, rice samples harvested on 23, 26 and 42 days after heading (DAH) were compared on their yield, color intensity, and proximate compositions. The maximum paddy yield of Green Rice$^{(R)}$ was 61.4% at 23 DAH, which decreased to 45.4%, 5.5% at 26 and 42 DAH, respectively. Greenness was darker at 23 DAH ($-0.27{\pm}0.03$), and significantly weaker (p<0.05) at 26 DAH ($0.07{\pm}0.01$) and at 42 DAH ($5.25{\pm}0.08$). All proximate compositions, except carbohydrate, including moisture, crude fat, protein, ash and total minerals were higher in the earlier-harvested Green rice$^{(R)}$ than in brown rice, without variations among the 23 and 26 DAH Green rice$^{(R)}$. Overall, the optimum harvest time of Jinbu Green Rice$^{(R)}$ at Gyeonggido would be 23 DAH. We suggest that timely harvesting could be a potent determinant of the quality of Green Rice$^{(R)}$.
