  • In order to examine the effect of oil extraction methods on the charateristics of sesame oil, the fractionation pattern and fatty acid compositions of the each fraction of the oil were compared in the oil extracted by the three different extraction methods, that is, pressure extraction of roasted seed (RTP), acetone extraction of roasted seed (RTE) and acetone extraction of raw seed (RWE). The amount of triglyceride in RWE oil was slightly higher as 77.2% of the total lipid than that in RTP and RTE oil of 73.4%. The content of oleic and linoleic acid in glycolipld and fatty acid fractions, linoleic acid in triglyceride, and palmitic and stearic acid in phospholipid fractions from RTP and RTE oil were higher than those from RWE oil, but the oleic acid in triglyceride. Palmitic and stearic acid in free fatty acid, and oleic and linoleic acid in phospholipid from RTP and RTE oil were lower than those from RWE oil. The ratio of $C_{18}$ to $C_{16}$ fatty acids and unsaturated to saturated fatty acids in glycolipid and phospholipid fractions from RTP and RTE oil were higher than those from RWE oil, but the ratios in triglyceride and free fatty acid fractions from RTP and RTE oil were lower than those from RWE oil.

  • Korean vegetable dishes-Na mul are indigenous and popular foods for a long time, and have been eaten by not only the common people but also the royale people in the ordinary meal and customary affairs. Grains are principal item of diet for Koreans and additions of Na mul in diet provide the nutritional minerals and vitamins. Especially vegetable oils in seasoning played the important role in nutrition balance. This manuscript historically investigate the Korean vegetable dishes-especially Na mul, Seng chae, Ssam, and the vegetables, additional ingredients and seasonings. 1. Foreign vegetable were introduced very actively. As the result of it, the more variety of vegetables are available. 2. Vegetable oils such as sesame oil, perilla oil, roasted sesame seed and pine nuts, etc were widely used for seasonings. 3. Seng chae dishes had been prepared with more than two different kinds of vegetables. Seasonings are used from the various sources, and combination of ingredients and development of condiments are expected to research further. 4. Ssam foods basically used uncooked vegetables, but steaming and boiling are also common methods.

  • The contents of sterols and stanols in vegetable oils and mist oil were analyzed by gas chromatography using a capillary column. The total sterol contents showed high values of 0.67~0.89g/100g in corn oil, rice bran oil, red pepper seed oil and sesame oil. Mist oil, a byproduct of soybean oil manufacture, was a suitable raw material for the production of stanol since it showed high sterol content (10.2g/100g). In the hydrogenation of sterol contained in mist oil using Pd catalyst, the effects saponification of oil were examined. The conversion of sterol to stanol was improved by a factor of 4~5 through saponification of oil, compared to the reaction without saponification.

  • Sesamin and sesamolin, antioxidant lipidsoluble lignan compounds, are abundant in sesame (Sesamum indicum L.) seed oil and provide oxidative stability of oil related to sesame quality. The sesamin and sesamolin contents of 403 sesame land races of Korea were determined by HPLC analysis of methanol extract (HPLC value), and their total lignan content was compared with those by using UV-Vis spectrophotometric analysis (UV method) of methanol (UV-MeOH value) and hexane (UV-Hexane value) extracts. HPLC values of total lignan content were strongly associated with UV-Hexane (r=0.705**) and UV-MeOH (r=0.811**) values. The UV values from both the extracts were 3.8-4.7 times higher than those of HPLC values. Lignan content was overestimated by UV method because total compounds in the mixture solution were quantified by absorbing at the same ultraviolet wavelength as in HPLC method. UV method could more rapidly analyze small amount of sample with higher sensitivity of detection than HPLC method. Average contents of lignans in sesame germplasm evaluated in this study were $2.09{\pm}1.02mg/g$ of sesamin, and $1.65{\pm}0.61mg/g$ of sesamolin, respectively, showing significant variation for lignan components. The results showed that UV method for the determination of sesamin and sesamolin could be practically used as a faster and easier method than HPLC by using the regression equations developed in this study.

  • Sesame (Sesamum indicum L.) is a rich source of edible oil most commonly it is used as a food product mainly in bakeries and also use as a common source of oil in daily kitchen needs. Due to the presence of some special phytochemicals like proteins, fibers, oil, minerals and antioxidants it is highly used for medicinal and therapeutic purposes. It is a good source of energy and act as an antiaging agent. Its seeds are used as Anti-helmintic, antihypertensive, antimicrobial, cytotoxic and Hepatoprotective but its seed coat which is a byproduct of sesame and a cherished source of fibers is normally use for animal feedstuff. In Unani system of medicine it is used both as drug & diet (dawa wa ghida). In classical Unani literature it is indicated in various disorders like Asthma, Dry Cough, Gastritis (due to any drug, excessive use of alcohol), Dryness of Intestine, Dryness in throat, Renal Stone, Bleeding Piles, Amenorrhea, Retention of urine, Dysuria, Orchitis, Sexual Debility, Anorexia. The present review article, an attempt have been made to compile all the pharmacological and Pharmacognostical characters of Sesamum indicum with special reference to Unani literature.

  • Studies for the commercial production of sesame oil using th supercriticl carbon dioxide were made. Characteristics of sesame oil containing one of natural antioxidant 'sesamol', which only exist at sesame seed were also studied during the supercritical fluid extraction. Among the various factors influencing the sesamol contents in the sesame oil, the roasting time and temperature were checked, because sesamol can be converted from sesamol in through pyrolysis. We found that the sesamol content was increased rapidly under the condition of roasting temperature over $200^{\circ}C$ with longer roasting time. The sesamol content was increased as the temperature and pressure increased, which was caused by increase of solubility of sesamol against sesamol oil. And the sesamol content was increased also with lower speed of supercritical fluid, which increased the contact time with the raw material. The sesamol content was also increased using water increase up to $1\%$ as the entrainer. When the extraction performance with the supercritical fluid was compared to the conventional compressed extraction, the sesamol content was increased up to 11.5 times with the entrainer.

  • The 165 collections originated from domestic and foreign countries were tested to evaluate the fatty acid composition of sesame for using as a basic research for oil quality improvement. The Korean and American varieties were lower content in saturated fatty acid and higher especially in unsaturated fatty acids (Oleic and Linoleic acid) than those of other regions. Varieties from temperate areas were higher in unsaturated fatty acid than that of varieties from tropical areas. On the other hand, the varieties which were late matured and had yellow seed coat color and set three capsules showed higher in unsaturated fatty acids than those of early matured, white seed coat and one capsules. Since there was significantly negative correlation between unsaturated fatty acid and saturated fatty acid contents, it was possible to improve the fatty acid composition of sesame.

  • This study was conducted to obtain the fundamental information on antioxidant component as affected by process of grain filling in different plant types of sesame. Sesamin and sesamolin as antioxidant components, oil content and seed weight were investigated for two plant types with different by branching habit. The sesamin and sesamolin contents in grains followed a pattern of increase immediately after flowering in branch type and monocapsule habit than non-branch type and tricapsule habit. But they started to decrease around 45 days after flowering, which oil content and seed weight continued to increase until maturity. The sesamin content increased quickly up from 10th to 40th day after flowering and showed almost maximum at 43th day after flowering. The sesamolin content increased quickly up from 20th to 30th day after flowering and showed almost maximum at 45th day after flowering. The oil content increased quickly up from 20th to 30th day after flowering and showed almost maximum at 47th day after flowering. The seed weight increased quickly up from 20th to 40th day after flowering and showed almost maximum at 48th day. The sesamin content, sesamolin content, oil content and seed weight showed almost maximum at from 43th to 48th day after flowering. So that this period was considered to be of physiological maturity.

  • Effects of phosphorous fertilizer on the growth habit and yield of monoculm and branch types of two leading sesame varieties was investigated. The photosynthetic rate of at each growing stage was high at the flowering stage. The photosynthetic rate of monoculm sesame variety, Pungnyeon was high prior to flowering stage, while the Kwangsan variety, branch type was high after the flowering stage. The level of phosphate were most effective in increasing photosynthesis when standard level of fertilizer was applied in both varieties. Kwangsan variety showed higher photosynthetic rate per unit area, higher NAR, and CGR and higher LAR and RGR at the maximum flowering stage than the Pungnyoeon variety. Those characters attained maximum level when standard levels of phosphorous fertilizer were applied. The protein and oil content of seeds were higher in Kwangsan variety compared with Pungnyeon. However, the carbohydrate of seeds was high for Pungnyeon variety. The highest protein content was attained when standard level of fertilizer were applied. The oil content appeared to increase as the level of applied fertilizer increased. The results suggest that the vegetative growth and seed yields of sesame may be enough with present level of fertilizers. However, higher amount of phosphorous fertilizer may be required to increase the oil content of sesame seeds.
