  • The whole berry, pulp, and seed of sea buckthorn fruit were extracted with supercritical $CO_2$ to produce edible oils. The effects of extraction pressure, temperature, and $CO_2$ flow rate on the oil yield and extraction rate were investigated, and the fatty acid composition, tocopherol, and carotenoid contents of the oils were compared. The results showed that the extraction rate was affected by pressure, temperature, and $CO_2$ flow rate and, in general, the yield increased with a rise in any of the 3 variables. Fatty acids in the whole berry and pulp oil were dominated by monounsaturated fatty acids (>64%), followed by saturated fatty acids (about 30%). In contrast, fatty acids in the seed oil consisted mainly of polyunsaturated (>60%) and monounsaturated fatty acids (>24%). The seed oil had a slightly higher content of tocopherols, but a much lower content of carotenoids, compared with the whole berry or pulp oil.

  • This study was conducted to prepare high quality grape seed oils by solvent extraction and chemical refining process. Additionally, quantitative analysis of several functional components in grope seed was carried out to compare quality characteristics of grape seeds from grapes grown by conventional and organic agricultural practices. There are no significant differences in several functional constituents of grape seeds between conventionally cultivated- and organically cultivated-grapes, although some functional compositions of grape seeds are different between two cultivation methods. The dried grape seed was pretreated with roasting heating for 5 min, milled and then extracted twice with n-hexane under reflux at $50^{\circ}C$ for overnight, followed by filtration and evaporation. The crude grape seed oil was successively purified by degumming with $0.1\%\;H_3PO_4$, deaciding with $20\%\;NaOH$, and then decoloring and deodorization by a steam distillation, and thereby producing purified grape seed oil(yield: $5.0\%/dried$ grape seed). Physicochemical characteristics of the purified grape seed oil were comparable to those of the imported grape seed oils.

  • Influences of different seeding dates on growth, seed yield, fatty acid composition and oil content were investigated in flax plants for two years. The results indicated that plant height in early seeding date was higher than that of delayed seeding dates during first season. Furthermore, seeding date also significantly affected the ripened seed rate and the rate increased with the delay in seeding date in first season. Seed yield in the first crop season was significantly higher than the second crop season. Palmitic acid showed variation in different seeding dates. Contrarily, stearic acid was stable and did not changed by different seeding dates. Linolenic acid was found in highest amount in all seeding dates consecutively in two cropping years. Highest oil content was recovered from the seeds of flax sown at 29 Apr. and May 9 in first and second cropping year respectively.

  • Peanut is one of the principal oil seeds in the world as a rich source of edible oil and protein. Peanut quality arises as a result of a complex interaction of genetic, physiological and biochemistry processes that produce the chemical composition of the peanut seed. The major factors influencing seed quality are degree of maturity and digging and drying, curing and storage as a series of harvesting. The end products, peanut butter, salted seed, confections, roasting stock and by-products are favored in world-wide because of their unique roasted peanut flavor, Literatures are reviewed mainly focusing on the physiological properties and nutritional quality of oil, protein and flavor in peanut. Chemical properties of protein and oil, and volatile flavor component in peanut seeds are studied. The objectives of this paper were to review and summarize the results obtained from the improving quality breeding program and evaluation of the chemical composition in peanut up to now.

  • This study was conducted to investigate the possibility that oil seed rape could be used as a forage fodder crop and to select the most suitable variety of forage rape at the southern area of Korea, Two varieties of oil seed rape currently grown for oil production and six introduced varieties of forage rape with relatively high yield and high nutritional value were grown at the same condition and their nutritional value were observed in Spring. Generally, rape was considered as a useful forage fodder crop with high content of crude protein and low contents of NDF, ADF, hemicellulose, cellulose and lignin. Differences in mean values of the above characters between two groups of rape were not statistically significant. Velox showed significantly higher content of crude protein and significantly lower contents of NDF, ADF, hemicellulose, cellulose and lignin compared with other varieties of forage rape in spring. Rape was relatively high in IVDMD compared with other forage fodder crops, and forage rape was more or less in IVDMD and DDMW than oil seed rape. Velox was the highest in IVDMD and DDMW among the varieties of forage rape in Spring, in this experiment.

  • Effects of green tea seed oil intake on the serum cholesterol, the thiobarbituric reactive substances (TBARS) formation of liver and inflammatory markers of plasma and macrophage in cholesterol fed mice were investigated, comparing to the intakes of corn oil and olive oil. C57BL/6 mice were divided into three groups and fed the experimental diets: supplemented corn oil, green tea seed oil and olive oil to cholesterol diet, respectively, at the level of 10% for 9 weeks. The increased levels of serum cholesterol of green tea seed oil group were significantly (p<0.05) lower than that of corn oil group until 6 weeks. The TBARS formation in liver of green tea seed oil and olive oil groups were significantly (p<0.05) reduced than those of corn oil group. The contents of inflammatory markers ($LTB4,\;TNF-{\alpha},\;PGE2,\;NO$) in plasma and macrophage did not show significant differences among the experimental groups. These results showed that green tea seed oil could exert the activity of decreasing serum cholesterol and the antioxidative activity in cholesterol fed mice liver. Therefore, we suggest that green tea seed oil might be developed as a high quality edible oil.

  • Near infrared spectroscopy (NIRS) is a rapid and accurate analytical method for determining the composition of agricultural products and feeds. An important merit of the NIRS analytical system is consistent predictions across instruments. However, proper calibration is the most important factor for a NIRS analytical system. Forty samples were obtained from Kyonggi-do Agricultural Research and Extension Services, and used to develop calibrations for crude protein content and crude oil content. Calibrations equations were developed using multiple linear regression (MLR). Accuracy and precision of NIRS predictions were adequate for quality measurement for the two constituents in kidney bean seed. In calibration sample sets (N=30), multiple correlation coefficient between NIR and lab measurements is 0.90 for seed, 0.97 for powder in seed protein concentration and 0.40 for seed and 0.92 for powder in seed oil concentration, respectively. It is concluded that NIRS method is suitable for the determination of seed composition in whole kidney bean.

  • The volatile oils of the fresh leaf and seed of parsley(Petroselinum crispum) were isolated by simultaneous steam distillation and extraction procedure. The compositions of the resulting oils were investigated by gas chromatography and gas chromatography-mass spectrometry. The volatile oil contents of leaf and seed were 0.06 % and 3.11 %, respectively. Fifty-eight components including 15 partially characterized components were identified in leaf oil and 23 components in seed oil. Seven of them are suggested as new parsley leaf volatiles. Terpenoids were represented as much as 46.4 % of total leaf volatiles and 49.3 % of total seed volatiles. The leaf volatiles contained a lot of myrcene(3.02%), 4-isopropenyl-1-methyl benzene(4.52%) and p-1,3,8-menthatriene(10. 49 % ), but the seed volatiles were characterized by greater quantities of the isomers, ${\alpha}-pinene$(22.28 %) and ${\beta}-pinene$(16.20 %), although these compounds were contained only trace in leaf volatiles. Of the components identified in both oils, the most abundant component was myristicin, constituting 21.80 % of the leaf volatiles and 47.54 % of the seed volatiles.

  • An experiment with twenty crossbred goat kids (male) of 2-3 months old, weighing about 12 kg was conducted to study the effect of feeding formaldehyde treated rape seed oil cake based diet supplemented with molasses on growth rate and histopathological changes of different organs. Goats were randomly divided into four groups of 5 animals each and were individually fed for a period of 120 days. The animals in group I (URC) and II (URCM) were fed concentrate mixture (CM-I) containing untreated rape seed oil cake (30%) while, the animals in group III (TRC) and IV (TRCM) were offered concentrate mixture (CM-II) containing formaldehyde treated rape seed oil cake. Further, molasses as energy source was additionally supplemented with the concentrate mixture at the rate of 8% of concentrate mixture on dry matter basis to animals in group II and IV. All the animals were maintained on roughage (Berseem hay:wheat straw = 2:1) and concentrate in 50:50 ratio. Average daily gain (g/d) of animals in group IV was significantly (p<0.05) higher than that in group I., but at par with group II and III. Feed conversion efficiency was also significantly (p<0.05) higher in group IV (10.14) than group I and II but at par with group III. The growth rate however increased by 50.2% in group IV showing more consistency in maintaining highest growth rate due to better balance of nutrients. At the end of four months of feeding trial, two animals from each group were sacrificed for histopathological study of different organs. Significant histopathological changes in liver, heart, lungs tissue of animals fed untreated rape seed oil cake diet were recorded which were totally absent in the organ of animals fed formaldehyde treated cake. The liver tissue of goats receiving control diet (containing untreated rape seed oil cake) were found to be associated with engorged central vein and blood vessels. Hepatocytes were swollen, pale and degenerated with cellular infiltration and fibrosis of portal areas. The muscles of heart were found to have intermyofibral edema. Emphysema accompanied by dilated and ruptured alveoli was also recorded in lung tissue. However, histopathological examination of various tissues of goats fed formaldehyde treated cake diet did not exhibit any degenerative changes. Additional supplementation of molasses with or without treated cake diet, apparently did not have any significant effect on ameliorating the above degenerative changes.
