초록

In order to increase the enzymatic activity of malt used as a source of traditional processing foods, the enzymatic activities of various barley were examined and the effects of ozone and light illumination treatment on the enzymatic activities of amylase, amylase, and glucanase in malt during man ufacture were also examined. Barley didn't show amylase activity prior to soaking, but the activity of barley increased quickly after soaking. Glutinous barley showed the highest amylase activity among Duru barley, Ol barley, two rowed barley and naked barley. Naked barley showed the lowest activity. The amylase activity was the highest in Duru barley and decreased in the order of in glutinous barley, naked barley and two rowed barley. It was showed that the enzymatic activity of malt was higher than that of control when malt was soaked for 24hr at the concentration of 0.3ppm of ozone. The enzymatic activity of malt treated with light illumination was higher than that of control. The bud and root of light illuminated malt was much stronger than that of control. The root of light illuminated malt was much shorter than that of control. In addition, light illuminated malt showed a little green color which matches the demand of consumer. These studies demonstrated that both ozone and light illumination treatment increased the enzymatic activity of malt to result in high quality of malt manufacture.
