To obtain basic information for the quality evaluation, the introduced or domestic sesame seeds were investigated to measure proximate components (crude protein, ash, mineral and oil) and isolated by preparative HPLC system for lignan contents. Although crude protein contents were the highest in Sudan sesame seeds, lipid, ash and mineral contents were not significantly(p<0.05) different between introduced and domestric sesame seeds. Unsaturated fatty acids such as oleic and linoleic acids were the highest in the domestic sesame seeds. The Mg content of domestic sesame seeds also was larger than that of introduced sesame seeds. A Ca content of domestic sesame seeds, however, was significantly (p<0.05) lower than that of China. Lignan contents, the most important component known as antioxidant, were significantly (p<0.05) higher in domestic sesame seeds than other sesame seeds tested. Our findings suggest that domestic sesame seed has the best quality in terms of the functional components.

the purpose of this paper is to study on the proximate composition, mineral and saponin content in white sesame, black sesame, and perilla seed. For this purpose, we have compared six different materials: white-raw-sesame, white-roast-sesame, black-raw-sesame, black-roast-sesame, raw-perilla seed and roast perilla seed, and have come to the following results. The crude fat content was the highest in white-raw-sesame(55.3%). In all the six samples, the crude fat content in raw seeds was all higher than that in roast seeds. The crude protein content was the highest in the roast perilla seed(24.6%), and in the six samples, the crude protein content in roast seeds all higher than that in roast seeds. The total sugar content was found to be the highest in the roast perilla seed(8.29%). The reducing sugar content was higher in raw perilla seed(1.57%) than in other sample materials. The ash content was the highest in black raw-sesame(5.93%), and that percentage rates was the same as that of FAO and of Japan. Minerals like Cd. Mn. Cu. Na. Mg. Pb. and Ca. were found to be contained more in black sesame than in other sample materials. The minerals contained most in white sesame were Zn.(61.6ppm) and Fe(49.4ppm), and K was contained a little more in perilla seed than in the others. The sample materials which contain saponin most were white-roast-sesame(0.34%) and black-roast-sesame(029%).

In this study, we found that the moisture content of black sesame seeds increased in proportion to steaming time, and it decreased in reverse proportion to the roasting temperature and time. The crude fat and crude ash contents were shown to be in the order of steamed black sesame>raw black sesame and roasted black sesame>raw black sesame, Crude protein decreased in reverse proportion to the steaming time, and more crude protein was found in the raw black sesame samples than in the roasted black sesame samples. The contents of sesamin, sesamolin, and total lignans were shown to be in the order of roasted black sesame>raw black sesame>steamed black sesame. In the steamed black sesame samples, sesamin showed its highest level with 20 minutes of treatment, and sesamolin showed its highest level with 15 minutes of treatment. In the roasted black sesame samples, sesamin, sesamolin, and total lignans showed their highest levels with 15 minutes of treatment at $100^{\circ}C$. The phenolic compound content increased in proportion to steaming time in the steamed samples, and reached a peak after 15 minutes of treatment at $100^{\circ}C$, and then decreased after 20 minutes. SOD-like activity reached a peak after 15 minutes of treatment, and in the roasted sample it reached a peak after 15 minutes of treatment, and then decreased after 20 minutes. SOD-like activity was comparatively lower than tocopherol and higher than sesamol. The intensity of electron donating ability, following 30 minute treatments, was shown to be highest in the steamed black sesame samples after 25 minutes of treatment, and next highest in the roasted black sesame samples after 15 minutes at $100^{\circ}C$. The electron donating ability was comparatively lower than tocopherol and sesamol. With regard to lecithin's antioxidant effects, the steamed samples showed a higher oxidation restriction rate in proportion to time, and the roasted samples showed the highest rate after 15 minutes of treatment, and then decreased after 20 minutes of treatment. for hydroxyl radical scavenging, similar scavenging activity to tocopherol, and comparatively higher scavenging activity than sesamol, was shown in all samples: all samples showed scavenging abilities of 90% or higher. In summary, this study applied three different treatment methods to black sesame to determine the optimum treatment conditions, and also examined the antioxidant effects and functional characteristics. The results showed that roasting can be used for other purposes than producing oil, and also suggested that methods other than roasting can be used in a variety of ways in cooking. Also, the different treatment methods can be applied in cooking in a variety of ways, to enhance functionality and preference.

The objective of this study was to standardized the cooking method of Imjasootang, a traditional health food in summer. By mixing chicken soup with 20 g (I$_1$), 30 g (I$_2$), 40 g (I$_3$), 50 g (I$_4$) of seasam seeds, the distinctive characteristic and level of preference of Imjasootang were examined through the analyses of the proximate composition, fatty acid contents, color index, turbidity, brix$^{\circ}$, and sensory evaluation. 1. The proximate composition of Imjasootang was 90.2∼95.1% of total moisture, 0.985∼1.271% of crude protein, 0.90∼0.98% of crude fat, 1.592∼2.456% of nonfiber, 0.003∼0.004% of fiber, and 0.77∼0.97% of crude ash. Fatty acid were composed of 15.15∼17.36% of saturated fatty acid and 79.73∼82.54% of unsaturated fatty acid. Imjasootang contains high level of oleic acid and linoleic acid which were dependant on the content of seasame seeds. 2. For color index of samples, the lightness ranged 47.2∼56.9, “a”values 1.82∼2.15%, and “b”values 15.5∼16.5%. The turbidity of samples ranged 39∼61%, in which I$_4$ (chicken stock 100 g+sesame seed 50 g+water 25 g) was the most turbid. Solid content was also the highest in I$_4$, ranging 1.4∼5.1%. 3. In sensory evaluation, all sesame seed Imjasootangs had no significance differences in appearance. The higher the level of sesame seed in Imjasootangs, the more Imjasootang was preferred in terms of nutty aroma, color nutty taste. and viscosity. I$_4$ had the strongest nutty aroma. I$_2$ (chicken stock 100 g+sesame seed 30 g+water 15 g) and I$_3$ (chicken stock 100 g+sesame seed 40 g+water 20 g) were the best in the overall preference.

A compact and handhold near infrared (NIR) system using microspectrometer was developed. This system was suitable not only in the laboratory, but also in the field or in the process. This system was first applied for classification of geographical origin of herbal medicine such as ginseng and sesame. To identify the origin of ginseng on site, the portable NIR system is more suitable for real field application. For this study, using the compact NIR system, soft independent modeling of class analogies (SIMCA) with 1100-1750 nm NIR spectra was utilized for classification of geographical origin (Korea and China) of both ginseng and sesame. The accuracy of results is more than 90%. Quantitative analysis for petroleum such as toluene, benzene, tri-methyl benzene, and ethyl benzene was performed with partial least squares (PLS) regression with NIR 1100-1750 nm spectra. This study showed that the NIR method and gas chromatography (GC), which is a standard method, have good correlations. Furthermore, the ash content of Cornu Cervi Parvum was analyzed and the accuracy was confirmed by the developed compact NIR system.
