  • A trial product of monogranular compound fertilizer for sesame under vinyle mulching cultivations was manufactured using the principal sources of urea, diammonium phosphate and muriate of potash in combination with a filler of zeolite and a binder of liquid waste from glutamic acid fermentation. Two field experiments using transparent vinyl mulching for single-crop cultivation and black vinyl mulching for cultivation after wheat and barley cropping were carried out to evalute their effects on sesame and the results obtained were as follows. Plant height and stem diameter of the trial product in sesame plant were higher and better than those of NPK split application and NPK all basic application. As the yield of the trial product was higher and similar to the NPK application plots in transparent and black vinyl mulching treatment respectively, the one time basic application of a developed monogranular compound fertilizer for sesame was possible under vinyl mulching cultivation.

  • This study analyzed the intake of calories and nutrients based on the consumption of black beans. The survey was conducted on 124 college students (male: 42, female: 82), of whom 63.7% (79 students) were consumers of black beans. The calorie intake of the black bean intake group (1599.81±555.48 kcal) was significantly higher than that of the non-black bean intake group (1259.99±507.58 kcal) (P<0.01). The black bean intake group also showed a significantly higher intake of crude protein (P<0.05), plant protein (P<0.01), animal protein (P<0.05), crude fiber (P<0.001), plant calcium (P<0.001), plant iron (P<0.001), zinc (P<0.01), vitamin B2 (P<0.01), vitamin C (P<0.01), vitamin E (P<0.01) and folic acid (P<0.001) compared to the non-black bean intake group. There was a positive correlation between the frequency of black bean intake and crude fiber (P<0.05), plant calcium (P<0.05), plant iron (P<0.05), and folic acid (P<0.05). Overall, the black bean intake group was more likely to eat black sesame 13.82 times (95% CI=5.37, 35.55), white beans 10.79 times (95% CI=3.53, 33.02), mung beans 7.22 times (95% CI=2.58, 20.23), and brown rice 4.72 times (95% CI=1.88, 11.84), than the non-black bean intake group. In conclusion, we believe that black beans constitute a vital food ingredient that is necessary to provide Korean college students with a well-balanced diet.

  • This study was carried out to find optimum roasting condition of sesame seeds for making seed season and oil treated with different temperatures and time intervals. Sesame seeds with 17~18% of moisture content were treated under fixed and changed roasting temperature conditions. The fixed temperatures are ranged from 160 to $240^{\circ}C$ with $20^{\circ}C$ intervals. The changed temperatures were treated at low(160 and $180^{\circ}C$) and medium(200 and $220^{\circ}C$) for 10 minutes, and at high(220 and $240^{\circ}C$) for 3 minutes. Meanwhile, roasting times were 20-30 minutes longer under low temperature condition and 3-5 minutes shorter under high temperature condition. The optimum roasting temperature and time were determined as $220^{\circ}C$ and 3 minutes for producing seed season, and as $220^{\circ}C$ and 5 minutes for sesame oil, respectively, in roasting with small quantity of sesame seeds. On the other hand, in the large scale roasting condition, those showed $240^{\circ}C$ and 15 minutes in for producing seed season, and $280^{\circ}C$ and 10 minutes and $260^{\circ}C$ and 15 minute for producing seed season in white-colored sesame variety and black-colored sesame variety, respectively.

  • Survey of sesame crop in the cultivators' field in the district of Daejeon, Yuseong, Sintanjin, Nonsan and Keumsan revealed that Alternaria and Corynespora blights of sesame were wide spread and caused severe damage to sesame plants. Symptoms of a new disease of sesame in Korea caused by Alternaria sesami were spreading, dark-brown to black, water-soaked lesions which often could be traced the entire length of the stem. In severe infections, several lesions coalesced together involving a major portion of the blade and the infected leaves dried and usually dropped off. Symptoms of Corynespora blight, caused by Corynespora cassiicola, were irregular shaped, concentrically-zoned, light brown to reddish brown lesions which later coalesced and caused defoliation. Stem lesions were long, reddish brown streaks that often coalesced, blighting the plants. The optimum temperatures for mycelial growth of A. sesami and C. cassiicola were about $27^{\circ}C$ and sporulations of these 2 fungi were stimulated under alternating light and darkness. Mycelial growth and sporulation of A. sesami and C. cassiicola were the greatest on sesame oatmeal agar (SOA) and potato dextrose agar (PDA), respectively.

  • This study was conducted to identify the sensory characteristics of the Korean traditional confectionery, dasik, prepared under different conditions and to compare their consumer acceptance in Korea. To accomplish this, descriptive analysis of eight samples prepared using two types of rice cake powder, dasik (Rflour, Rflour_Omija), brown rice powder red ginseng dasik (Brice_Ginseng_P), pinepollen dasik (PineP), black sesame dasik (BSesame), bean dasik (Rbean), and two types of mungbean starch dasik (Starch_Omija, Starch_Greentea), was conducted by ten trained panelists. In addition, 81 consumers evaluated the overall acceptance (OL), acceptance of appearance (APPL), odor (ODL), flavor (FLL), and texture (TXTL) of the samples using a 9-point hedonic scale, as well as the perceived intensities of sesame flavor, sweetness, and hardness using a 9-point just-about-right (JAR) scale. Partial least square- regression (PLSR) indicated that the BSesame and Rbean samples, which had significantly (p<0.05) high roasted sesame, burnt, greasy, glossy, and cooked chestnut flavor scores, had the highest acceptability and consumer desire scores. Additionally, the PineP and Rflour_Omija samples, which had relatively high particle size, transparency, roughness, spoiled tofu, fermentation and raw rice flavor scores, were the least preferred samples. Therefore, roasted sesame, burnt, greasy, glossy, and cooked chestnut flavor attributes were considered drivers of "liking" whereas particle size, transparent, roughness, spoiled tofu, fermentation, and raw rice flavor attributes acted as drivers of "disliking" among consumers.

  • The feasibility of incorporating black sesame powder (BSP) as a value-added food ingredient into bakery products was investigated using a cookie model system. BSP was incorporated into cookies at different content: 0%, 2%, 4%, 6%, and 8% (w/w) based on the total weight of wheat flour. The spread ratio and loss rate of cookies increased significantly with increasing levels of BSP (P<0.05). All color characteristics, including lightness ($L^*$), redness ($a^*$), and yellowness ($b^*$), decreased with a higher amount of BSP. Use of BSP significantly reduced the hardness of cookies (P<0.05), but no significant differences were found between the control and 2%, 4%, and 6% samples (P>0.05). 2,2-Diphenyl-1-picrylhydrazyl and 2,2'-azino-bis(3-ethylbenzothiazoline-6-sulphonic acid) radical scavenging activities increased significantly (P<0.05). The consumer acceptance test indicated that addition of BSP up to 4% had a favorable effect on consumer preferences. Overall, cookies containing 4% BSP will add the advantage of the functional properties of BSP maintaining the consumer acceptability.

  • This study investigated the quality characteristics of madeleines prepared using varying amounts of roasted black soybean flour (RBF). The RBF was used to substitute 0% (control group), 20% (RBF-20 group), 40% (RBF-40 group) and 60% (RBF-60 group) of weak flour (WF) in the manufacture of madeleine. The substitution of WF with RBF showed decreased the pH but increased the sugar concentration of the batter (p<0.01). Low lightness (L) and low yellowness (b) were observed in the experimental groups at high ratios of RBF substitution (p<0.05). The experimental groups of madeleines showed higher hardness and chewiness than the control group (p<0.001). The principal component analysis of the RBF-60 experimental group, which had the highest proportion of RBF, showed that it had relatively strong characteristics with respect to "darkness", "soybean odor", "sesame odor", "grains odor", "savory flavor", "sweetness", "black soybean taste", and "moistness". The acceptance test results, showed that the RBF-20 experimental group was similar to the control group with respect to "odor acceptance", "taste acceptance", and "texture acceptance". Thus, this study confirmed the possibility of using RBF for the preparation of madeleines.

  • In this study, 17 kinds of polyphenols and 5 kinds of anthocyanins were analyzed to compare the contents of polyphenols and anthocyanins in 76 colored agricultural products. A total of 17 polyphenols were analyzed simultaneously by 9 phenolic acids (gallic acid, protocatechuic acid, chlorogenic acid, vanillic acid, caffeic acid, syringic acid, p-coumaric acid, t-ferulic acid, t-cinnamic acid) and 8 flavonoids ((+)catechin, syringic aldehyde, rutin, epicatechin gallate, naringin, luteolin, naringenin, kaempferol) and 5 anthocyanins (delphinidin-3-glucoside, delphinidin-3-rutinoside, cyanidin-3-galactoside, cyanidin-3-glucoside, cyanidin-3-arabinoside) were simultaneously analyzed. The total content of 17 polyphenols was determined as seoritae $255.1{\pm}7.5{\mu}g/g$, seomoktae $275.8{\pm}5.3{\mu}g/g$, black rice $78.5{\pm}4.6{\mu}g/g$, black sesame $75.8{\pm}3.2{\mu}g/g$, blueberry $143.3{\pm}5.5{\mu}g/g$, aronia $195.2{\pm}4.9{\mu}g/g$ and blackcurrent $131.6{\pm}3.2{\mu}g/g$, the highest content was found in the order of seomoktae > seoritae > aronia > blueberry > blackcurrant > black rice > black sesame. The total content of 5 anthocyanins was determined as seoritae $82.4{\pm}17.2{\mu}g/g$, seomoktae $95.2{\pm}6.1{\mu}g/g$, black rice $74.1{\pm}9.7{\mu}g/g$, black sesame were not detected, blueberry $110.8{\pm}1.9{\mu}g/g$, aronia $218.9{\pm}6.1{\mu}g/g$ and blackcurrent $209.7{\pm}4.0{\mu}g/g$, the highest content was found in the order of aronia > blackcurrant > blueberry > seomoktae > seoritae > black rice. These results indicated that seomoktae and aronia possessed the high level of functional components and further study will be needed to develop high value-added foods based on the colored agricultural products.

  • Sesame lignan, including sesamin and sesamolin has been reported to have various content according to accessions and environmental factors. The objective of this study were to analyze the lignan variation of 143 sesame accessions from core collection in Korea and to test the effects of growing years and locations on lignan and lipid content of Korea sesame elite lines. The results showed that the core sesame germplasm in Korea has broad variation of lignan content from 2.33 to 12.17 mg/g with an average 8.18 mg/g. Among tested sesame accessions, the IT184615 had the highest lignan content of as 12.17 mg/g. So this accession will be a good genetic resource for developing a high lignan sesame variety. The sesamin and sesamolin content for sesame accessions across origin had significant difference. The average lignan content of accessions collected from Russia (10.0 mg/g) and Nepal (9.08 mg/g) were relatively higher than other countries. The sesamin and sesamolin content for sesame accessions across seed coat color had significant difference. The average lignan content of sesame with white, brown and black seed coat color was 8.61, 7.51, and 5.49 mg/g, respectively. The variation of lignan and lipid content was significantly different across elite lines, locations and growing years. Therefore, it is important to find sesame accessions having high lignan content with environmental stability.

  • This study had three purposes: (1) to investigate the enrichment levels and dispersion patterns of potentially toxic elements in the rock-soil-plant system; (2) to evaluate the uptake ratios of heavy metals from soils into plants and (3) to assess the chemical speciation of heavy metals in soils. Rock, surface soil and plant samples were collected in the Boeun area underlain by black shales of the Okchon Zone. These samples were analyzed for multi-elements using INAA, ICP-AES and AAS. The maximum abundance of U in black shales is 16 mg/kg and radioactivity counts up to 300 cpm. In particular, Mo, V, Ba, Cd, Pb and U are enriched in black shales. Most of soils derived from black shales show high concentrations of U, As, Mo, Ba, Cu, Cd, Pb, Zn and mean concentrations of As and Mo in soils (20 mg/kg of As and 6.6 mg/kg of Mo) are higher than the permissible level suggested by Kloke (1979). Enrichment index values of soils are calculated and higher than 1.0 in the black shale area with the highest value of 6.4. Mean concentration of Cd in plants is higher than those of Cu, Pb and Zn. The concentration of Cd in plant species decreases in the order of Chinese cabbage > red pepper > soybean=sesame > rice stalk > com > rice grain. The biological absorption coefficients (BAC) in plants are in the order of Cd > Zn=Cu > Pb, which suggests that Cd is more bioavailable to plants than Cu, Pb and Zn. From the results of sequential extraction analysis of soils, relatively high proportion of Cu, Pb and Zn are present as residual fractions whereas that of Cd as non-residual fractions. Cadmuim occurs predominantly as exchangeable/water-acid soluble phase in soils, and Cd is more mobile and bioavailable than Cu, Pb and Zn.
