  • Vitamin E, consisting of tocotrienols ($\textrm{T}_3$) and tocopherols ($\textrm{T}$) is well-known nutraceutical compound for its antioxidant, anticancer and cholesterol-low-ering activity. The contents of alpha ($\alpha\textrm{-}$), beta ($\beta\textrm{-}$), gamma ($\gamma\textrm{-}$) and delta ($\delta\textrm{-}$) tocotrienols and tocopheyols in some Korean crop seeds were evaluated by using HPLC after saponification. Among tested crops, total 73 contents (mg/110g) were purple perilla 25.06, barley 4.50, corn 3.54, iris 3.04, adlay 2.58, safflower 0.12. Other crops including 5 soybean cultivars, kidneybean, sunflower and perilla contained no tocotrienols. Regarding $\textrm{T}_3$ isomers, $\beta\textrm{-}$$\textrm{T}_3$ were rut observed in adlay and corn, and $\delta$-$\textrm{T}_3$ were not in iris aid purple perilla, while safflower exhibited no detectable $\alpha\textrm{-}$, $\beta\textrm{-}$ and $\delta\textrm{-}$$\textrm{T}_3$. Total T contents (mg/100g) were high in iris (51.82), perilla (40.90), soybean (34.11), sunflower (20.88), and they all contained all $\alpha\textrm{-}$, $\beta\textrm{-}$, $\gamma\textrm{-}$ and $\delta\textrm{-}$ tocopterol isomers. Total Vit E contents (T + $\textrm{T}_3$, mg/100g) were iris 54.86, purple perilla 41.80, perilla 40.90, soybean 34.11, sunflower 20.88, safflower 14.73, corn 11.49, evening-primrose 10.07, barley 7.48, adlay 6.24 and kidneybean 5.27.

  • This study was carried out to investigate the effect of soaking time of seed disinfectant, Fludioxonil on the germination and disease occurrence of adlay (Coix lacryma-jobi L. var. ma-yuen Stapf). The germination rate was higher in the seed disinfectant treatment for 3 days followed by seed soaking for 3 days than that of other treatments under controlled condition of low temperature. The value of two experiments were 90.8%, 96.7%, repectively. And, the time of seed soaking was longer, the more seed rot was proportionly decreased. In the pot and field experiment, germination rates were somewhat low compared to that of petri dish experiment as 88.3%, 84.3%, and occurence of seedling blight showed similar results that of petri dish experiments. There was not significantly different in the yield components among treatments in the field. However, as compared with untreated plot (194kg/10a), unhulled grain yield was increased about 26% on that treatment. Based on these results, it has been thought that improvement of the germonation rate and decrease of disease occurrence of adlay were accompanied with the seed disinfectant during 3 days followed by seed soaking during 3 days before sowing.

  • Adlay bran is a waste product previously thought to have no commercial value, Its methanolic extract was fractionated using n-hexane (ABM-Hex), ethyl acetate (ABM-EtOAc), 1-butanol (ABM-BuOH), and water (ABM-$H_2O$). The ABM-EtOAc fraction exhibited a strongest inhibition against growth of human lung cancer cell A549 and human colorectal carcinoma cells HT-29 and COLO 205. Inhibition of cell cycle progression at $G_0/G_1$ transition, increase of cells at the sub-$G_1$ phase, and DNA ladders were observed in cells treated with ABM-EtOAc. The ABM-BuOH fraction showed the strongest inhibition of proinflammatory cytokines tumor necrosis factor (TNF)-$\alpha$ and interlukin (IL)-$1{\beta}$ in stimulated RAW 264.7 macrophages. Further, ABM-EtOAc and ABM-BuOH inhibited cyclooxygenase (COX)-2 expression in A549 and HT-29 carcinoma cells, while COX-l expression was not affected. These results reveal that both ABM-EtOAc and ABM-BuOH may aid the prevention of cancers and the applications in cancer chemotherapy.

  • A total of 244 cereal samples (oat, sorghum, adlay, and proso millet) were collected from fields to examine the contamination of Fusarium mycotoxins in cereals during harvest season in 2017 and 2018. The contamination levels of deoxynivalenol (DON), nivalenol (NIV), and zearalenone (ZEA) were analyzed individually by using the immunoaffinity column clean-up method with ultra performance liquid chromatography, and fumonisins (FUM) were analyzed by using the QuEChERS method with liquid chromatography-mass spectrometry. Highest level of NIV contamination (120.0-3277.0 mg/kg) was observed in oat samples among the analyzed cereals. In the adlay samples, DON contamination was the highest (maximum level 730.0 ㎍/kg). The proso millet samples had a high frequency of detection of NIV and ZEA (61.5% and 57.9%, respectively), but the levels were low (average detection level of NIV, 75.6 ㎍/kg, for ZEA, 21.5 ㎍/kg). Among the cereal samples, sorghum had the highest contamination frequency of DON, ZEA, and FUM, and the co-occurrence of Fusarium mycotoxin was 70.0%, which was higher than the average of 29.9%. In order to safely manage Fusarium mycotoxin levels in cereals, continuous research on the development of contamination prevention technologies together with monitoring of mycotoxin contamination is needed.

  • Objective: This study was conducted to investigate the hygienic state and awareness of drink vending machines in a city. Methods: Twelve of the most frequently used vending machines in various areas were selected in October 2008. As soon as fresh samples of milk coffee and adlay tea were collected in sterile containers from each machine, the temperature was measured. The samples were carried on ice to the laboratory to test total plate counts and Escherichia coli contamination. College students were inquired about drink vending machine hygiene by implementing self-developed questionnaires. Results: The temperature of 6 milk coffee samples (50.0%) and 8 adlay tea samples (66.7%) turned out to be inadequate. The total plate counts of milk coffee samples were all adequate, although 9 adlay tea samples (75.0%) were inadequate. All the beverage samples were negative for E. coli. In questionnaires obtained from 74 users of coffee vending machines, only 2 (2.7%) expected the hygienic state of vending machines to be good. There were 27 people (33.3%) that knew the existence of hygiene-related laws for vending machines. Conclusions: This study reveals that the hygienic state of drink vending machines insufficiently reaches the standard for the hot beverage and that most people are not aware of importance of vending machine hygiene. It is necessary to make improvement in the hygiene of vending machines and public awareness in this city.

  • In this review, the mycotoxin contamination of Korean cereals and their products is analyzed by crop based on scientific publications since 2000. Barley, rice, and corn were investigated heavier than the others. The common mycotoxins occurred in all cereals and their products were deoxynivalenol and zearalenone. Nivalenol was detected in all samples analyzed but more frequently or mainly in barley, rice, and oat. Fumonisin was commonly detected in corn and sorghum but also in adlay, millet, and rice. Adlay and millet were similar in the contamination pattern that fumonisin and zearalenone were the most frequently detected mycotoxins. Zearalenone was the most commonly detected mycotoxin with concentrations higher than the national standards (maximum limit), followed by deoxynivalenol, and aflatoxin. However, most occurrence levels were below the maximum limits for respective mycotoxins. This result shows that barley, rice, corn, sorghum, millet, and adlay are more vulnerable to mycotoxin contamination than other cereals and therefore continuous monitoring and safety management are necessary.
