Various Bam-dduk were prepared by using two kinds of chestnut flour (dried chestnut, boiled chestnut), 2 types of sugar (sugar and honey), and 3 levels of sugar (10, 20, 30 g), and they were evaluated for sensory quality, texture, moisture, and color. The addition of 10∼15% of dried chestnut flour to glutinous rice flour increased the graininess, moistness, chewiness, and sweetness of Bam-dduk, and the addition of 30∼40% boiled chestnut flour increased the graininess, moistness, and sweetness, depending up on the types and levels of sugar. The use of 10% dried chestnut flour and 30 $m\ell$ of honey gave the highest value of springiness in Bam-dduk. Gumminess, hardness and chewiness were the highest with 15％ dried chestnut flour and 20 g sugar. Cohesiveness was the strongest at 30% boiled chestnut flour and 10 $m\ell$ honey. Adhesiveness was most proper when 30 g sugar was added to 10％ dried chestnut flour. The use of boiled chestnut flour gave higher moisture content in Bam-dduk (32.2∼41.3%) than the use of dried chestnut flour (29.6∼34.2%). The values of 'L' (67.43) and 'b' (18.07) were most intensive in Bam-ddfik prepared with 15% dried chestnut and 20 g sugar, and the replacement of 20 g sugar with 30 $m\ell$ of honey gave the highest 'a' value, 2.33.

This study was undertaken to investigate the producibility of processed foods utilizing 6 newly developed non-glutinous rice cultivars. First, cooked rice, cake, cookies, bread, and slender rice cake sticks were prepared with the newly developed cultivars; then their physicochemical and textural properties were evaluated. The rice samples had similar pasting temperatures and peak times, but different viscosities and other pasting properties. The textural analysis results suggested that 'Chucheong' was appropriate for cooked rice due to its low amylose content; hardness, and springiness; 'Ilphumbyeo' for rice cakes due to its high amylose content, moderate cohesiveness and adhesiveness, and low hardness; 'Ilphumbyeo' for cookies due to its high amount of protein, and low cohesiveness and adhesiveness; 'Ilphumbyeo' for bread due to its high amylose content, moderate hardness, and low consistency; and 'Ilphumbyeo' for the slender rice cake sticks due to its low hardness, moderate breakdown, paste viscosity, and setback.

This study was conducted to determine the effects of microorganism inactivation using 3 ppm of aqueous ozone (AO), 1% citric acid, 1% lactic acid, and 1% acetic acid alone, as well as the combinations of AO and organic acid, for washing the raw materials of saengsik (carrot, cabbage, glutinous rice, barley) with or without agitation. The combination of AO and 1% of each organic acid significantly inactivated spoilage bacteria in both the vegetables and the grains (p<0.05). However, in the glutinous rice, no inhibitory effects were shown for total aerobic bacteria by using water, ozone, or the combination of AO with citric acid or lactic acid, without agitation. Microbial inactivation was enhanced with agitation in the grains, whereas dipping (no agitation) treatments showed better inhibitory effects in the vegetables than in the barley, suggesting that washing processes should take into account the type of food material.

Paddy rice is typically stored during postharvest until rice grain is processed into brown rice and milled rice by hulling and milling procedure, respectively. Recently, instead of storing paddy rice, storage of brown rice has been in the spotlight because it is more convenient and economically feasible. Different brown rice cultivars with varying amylose contents including waxy rice, medium-waxy rice, and non-glutinous rice were stored in room temperature storage for four months, and the changes in grain qualities of brown rice were evaluated. Amylose content significantly affected pasting properties in which rice cultivar with higher amylose content showed longer pasting time and higher peak viscosity. Storage also affected pasting viscosities, showing an increase in peak viscosity, but a decrease in breakdown viscosity. The changes in pasting viscosity during storage could be an important starch property for aged brown rice utilization. Waxy brown rice showed the weakest aging property in terms of free fatty acids (FFA) accumulation, whereas non-glutinous rice was more substantial grain quality against aging. The FFA values of two months storage were not significantly different from the initial FFA contents, suggesting that brown rice stored in room temperature for two months could be feasible for direct consumption of brown rice.

The purpose of this study was to improve the palatability of fermented red pepper soybean paste (Kochujang). Five individual models of Kochujang were prepared the following: control, glutinous rice containing 50% (A) and 100% (B) of barley, glutinous rice containing 1.5% (C) and 3.0% (D) of red rice. These Kochujangs were prepared and fermented for 60 days at 30 in a crock, and examined for changes in their physicochemical properties. There were no distinguishable change in their pH, acidity, formol-N content. L (lightness)-, a (redness)- and b (yellowness)-values were decreased rapidly until 20 days of fermentation. After 60 days, the values of L-, a- and b- of A, B Kochujang were increased than those of control, C, D Kochujang. Sensory profiles of color, flayer, taste and overall quality on the final products which fermented for 60 days showed that there were no differences in quality of each models. HMG-Co A reductase inhibitory activities were observed in 1.5% of red rice containing Kochujang.

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.
