To investigate the effect of sourdough on the characteristics of quality of barley bread, sourdough starter with Lactobacillus plantarum, Lactobacillus sanfrancisco and Enterococcus sp. were added to baking after 48 hours incubation at 37℃. 1. The pH of bread using Lactobacillus sanfrancisco starter was the lowest among tested starters. while the titratable acidity(TTA) of the strain was the highest, followed by Enterococcus sp.. 2. In bread, moisture contents of control were 38%. It was decreased during 6 days. The moisture contents of bread using Lactobacillus sanfrancisco starter were the highest among tested starters, followed by Enterococcus sp.. 3. Oneset temperature(To), peak temperature(Tp) and enthalphy (δH) were increased during storage of 6 days. The enthalphy of bread using Lactobacillus sanfrancisco starter was the lowest among tested starters, followed by Enterococcus sp..

A Lactic acid bacterium for barley bread was isolated from barley powder and was identified as Enterococcus sp. It was used as a starter for barley bread and quality of bread was compared with the bread prepared by conventional starter 1. The pH of bread making process using Lactobacillus sanfrancisco starter was the lowest among tested starters. while the titratable acidity(TTA) of the strain was the highest, followed by Enterococcus sp.. 2. In valorimeter value(v/v), control was 70, but dough using all starter was 60. The peak time and stability of dough using Lactobacillus sanfrancisco were the highest among tested starters. 3. Extensibility of dough using Enterococcus sp. was the highest among tested starters, followed by Lactobacillus sanfrancisco. Proper extensibility and maximum resistance were observed in Lactobacillus sanfrancisco.

A 5-day germination test is applicable to detect biological changes in irradiated wheat and barley at low doses. Seeds were irradiated at below 0.5 kGy, husked and placed on distilled water-moistend filter paper in a covered Petri-dish. Water was supplied everyday. To evaluate the growth rate, the length of shoots and roots was measured during germination. In wheat, the shoots of all samples grew well during 5 days, but the shoot length and the daily growth extent decreased with increasing doses. The roots of non-irradiated wheat showed the highest daily growth extent during 5 days and the root length was over 20 mm at 3rd day. In barley, the growth of shoots and roots was retarded at 0.3 kGy or more after 3 days. It was concluded that if the root length was 20mm or longer within 3 days, wheat and barley were identified as non-irradiated. The germination test was proved a promising screening method for the detection of irradiated wheat and barley.

Green Tea consists of 15-30% catechins (a type of polyphenol), which act as super antioxidants, inhibitory action against aging process. Antioxidants fight radical-free oxygen, an agent which can begin the process of cancer by damaging essential body chemicals and harming DNA. This study was peformed to develop the elderly diet using Green Tea as an inhibitory action against aging process. Nokchaborijook (Baley gruel added rice powder and Green Tea) was manufactured by various levels of Green Tea(1, 4, 7%) and the grinding period(15, 30, 45 sec). The optimum levels of added Green Tea and grinding periods on Nokchaborijook were determined with the results of sensory evaluation by response surface methodology and analysis of composition. The Anti-oxidant Vitamin A, C, E and Flavonoid were increased with increased levels of Green Tea and grinding periods be decreased. As the levels of Green Tea and grinding periods were increased, the green color and penetrated force became stronger. Among the sensory attributes, Bitterness, Green Tea Flavor and Hashness were greater depending on increasing Green Tea. Jujube flavor was greater relying on decreasing Green Tea. Greenness and spreadability of particles were increased as both the amounts of Green Tea and the grinding period were increased. This result was used to determine the optimum conditions of adding levels of Green Tea and grinding periods. The optimum conditions of Nokchaborijook was established as adding of 5.8% Green Tea grinded for 15 seconds.

The yield performance and nutrient quality of barley for pellets making from whole crop material were discussed during 1993-1994. Barley (cv. Olbori) was grown on paddy land after rice cutivation and was harvested at early stage of physiological maturity.

보리차 및 결명자차의 추출 공정중 추출량에 미치는 중요한 인자로는 입자크기, 추출온도, 추출시간, 및 초기시료의 농도 등이 있다. 그리하여 본 연구에서는 상기 추출조건의 변화에 따른 추출량을 측정하여 얻어진 경과를 요약하면 다음과 같다. 1. 추출량 및 추출속도 예측 모델식은 가장 오차가 적은 범위에서 각각의 독립변수에 대한 예측 모델식을 세운후 각 독립변수와의 관계를 종합하여 최종추출량 예측 모델식을 세웠다. 2. 입자의 크기가 총괄 물질전달계수에 미치는 영향은 입자가 작을수록 총괄물질 전달계수가 증가하였다. 3. 추출량은 입자크기가 작을수록, 온도가 높을수록, 시간이 길수록, 초기시료량이 클수록 증가하였다.
