  • It was confirmed that korean scabby barley during the summer of 1963 was infected with Gibberella zeae. Feeding experiments showed that the diseased grain was toxic and induced emesis in pigs. The concentrated extracts which contained the emetic principle were prepared by refluxing the grain with methanol or water for 5 hours and then concentrating the filtrates and the washing in vacuum. Animal tests proved that methanol extraction for the emetic principle was more effective than extraction with water.

  • In this report, some practical problems that are concerned with the infected barley were examined. Most of the toxic substance is present in the bran. It was almost impossible to remove the toxic substance with water or methanol completly, however, we found it is effectively eliminated by soaking the whole grain with 2%, calcium hydroxide suspension for 24 hours. As a detoxifying agent, kieselguhr was very effective; the grain mixed with little amounts (0.4-0.5%) of kieselguhr may be used as an animal feed.

  • Time-dependent flow properties of commercial kochujang (hot pepper-soybean paste) were evaluated at various shear rates (5, 15, 25, and $35\;sec^{-1}$) and temperatures (5, 15, and $25^{\circ}C$). Flow properties of all samples showed thixotropic behaviors, which were qualitatively evaluated and quantitatively described by the Weltman, Hahn, and Figoni and Shoemaker models. Time-dependent flow properties of kochujang were found to vary over the range of the shear rate and temperature investigated. Time-dependent models of Weltman and Hahn were suitable ($R^2=0.923-0.987$) for commercial kochujang.
