  • This study attempted to examine the effects on sensory characteristics, texture and color of steamed soybean rice cake in various levels of soybeans. Sensory evaluation was done by panels of 7 judges. Objective measurements were made by utilizing the Instron and Hunter Colormeter. The results were as follows; 1. The content of moisture, total ash, protein, fat and carbohydrate in rice were shown to be about 13.47%, 0.48%, 6.40%, 0.54% and 79.11%. Those of soybean were 10.95%, 4.54%, 30.67%, 20.36% and 33.48%. 2. The results of sensory evaluation revealed that rice cake containg 20% of soybean produced the best quality in most sensory characteristics. 3. By Instron measurement of various levels of soybean in steamed soybean rice cake, hardness and cohesiveness were not different. By color value of that, b value was tend to increase as the addition level of soybean.

  • Soybean and beanpaste have been used as ore of the important food in Korea. Beanpaste is made from soybean(seed of Glycine max $M_{ERRIL}$, Leguminosae) by traditional fermentation. It was expected that the secondary metabolites might be formed by the action of some microorganisms or enzymes on the constituents primarily contained in soybean during manufacturing or storage of beanpaste. A systematic investigation on the chemical constituents was carried out. As a result, sterol glycoside named daucosterin, lipo-daucosterin have been isolated from the lipid fraction soybean and their structures elucidated basis of chemical and physicochemical evidences. A ratio of composition of the lipid constituents in soybean and beanpaste were estimated.

  • The growth inhibitory effect of germanium, or soybean sprouts cultured with germanium, on cancer cells was determined in the cultured gastric cancer cell line, AGS. The growth of AGS was significantly inhibited by the addition of 0.01-1% organic germanium (Ge-132) and germanium stone powder in MTT cytotoxicity assays. The juice from germanium treated soybean sprouts (GTS) inhibited the growth of AGS gastric cancer cells by 78-88% at concentrations of 2.5 or 5${\mu}\ell$. The juice from Seomoktae GTS revealed an especially higher growth inhibitory effect than that from the control soybean sprouts (germanium non-treated soybean sprouts, GNTS) in AGS. The results suggest that soybean sprouts cultured with germanium may exert an anticancer effect against gastric cancer cells.

  • The purpose of the study is to examine the physicochemical and quality characteristics of fermented soybean paste sauce containing lotus leaf powder at concentrations of 0% (control), 2%, 4%, 6% and 8%. The color of increasing the amount of concentrated lotus leaf powder in the fermented soybean paste sauce tended to increase the pH, total soluble solids, saltinity and viscosity. It also tended to increase total polyphenol, flavonoids content and DPPH radical scavenging ability. The total bacteria numbers increased with storage period, and those of fermented soybean paste sauce with 4% lotus leaf powder were lower compared to the other samples. The results of this study suggest that lotus leaf is a beneficial ingredient for increasing quality characteristics and the functionality of fermented soybean paste sauce.

  • Soybean and mungbean sprouts are vegetables indigenous to Korea which have been grown throughout the year from the most remote age. They had been called interchangeably as duchaeah or duah. Control method of environmental conditions for soybean or mungbean sprouts growing had been already appreciated from long time ago. A growing method once developed might have been handed over considerable period. Siroo (시루) and yongsoo (용수) had been the most common containers and the watering skill is of the utmost importance for soybean sprouts growing. As the demand of soybean sprouts in the market increased, a pit has been used for bean sprouts growing, and transformed into regular soybean sprouts factory. Now bean sprouts are international food and the demand of bean sprouts seems permanent in Korea. Accordingly the long-term policy concerned with the production of soybean sprouts should be prepared, placing emphasis on improved quality and safety.

  • Antimutagenic effects of methanol extracts of various soybean pastes against aflatoxin B1 were examined using Salmonella typhimurium TA98 and TA100. Antimutagenic activities of boiled soybeans, Japanese Miso, traditional Korean soybean pastes, soybean pastes fermented by wild type strains, and soybean pastes fermented by mutants, transformants, and cell fusants were 53.6 to 54.6%, 73 to 79.7%, 78.3 to 95.7%, 85 to 97.1%, 71.9 to 78.3%, 65.5 to 77.7%, and 73.4 to 79.0%, respectively. Soybean pastes fermented by wild type strains showed higher activities than those fermented by mutant, transformant, and cell fusant strains.

  • This paper, is about the test on the operating performance of diesel engine by using of soybean oil which farmers could supply in their farm yard. The diesel engine used is a swirl-chamber type, four stroke cycle with single cylinder, air cooling and its rated horse power is 2 PS per 1300 rpm. Several results obtained are as follows; 1. The starting performance of diesel engine with soybean oil is almost the same as that with light oil. 2. The variation of engine speed according to various engine load is small when soybean oil is used compared with light oil. It is considered that soybean oil is desirable for the purpose of industerial power machine fuel. 3. The specific fuel consumption increases approximately 10 percent high in the condition of rated horse power and maximum horse power and shows less or same during the load test in low velocity, when soybean oil is used 4. Though the brake thermal efficiency in the condition of rated horse power and maximum horse power is inclined to decrease when soybean oil is used compared during the load test in low velocityt shows good inclination.

  • To develope the soybean sprouting equipment(a type of cabinet) for medium amount(one bucket; 10~13kg) production of soybean sprouts, the watering system was made of four siphons and four the bottle necked water tank. Diameter of four siphons used for development of the watering system were 8, 13, 17 and 21mm, respectively and their water exhausting volumes were 40, 92, 154, 524ml/sec, respectively. The watering system can be automatically watered 524ml/sec without electric supply. The soybean sprouting equipment is consisted of four the bottle necked water tanks with the four siphons and six sprouting buckets with net shaped bottom for water draining. The soybean sprouting equipment with the watering system may be produced more than one box a day in the condition of 6~7 watering times a day at 25~30oC.

  • In order to improve the shelf-life of Tofu, the elimination of contaminated bacteria by ozone treatment was examined. Tofu prepared from ozone treated-soybean was investigated for microbial, physicochemical and sensory changes during storage at 20$^{\circ}C$ and 30$^{\circ}C$. As a result of treatment in ozonic water by 2~4ppm/sec for 3 hours, 90~98% of the total bacteria in material soybean for Tofu was eliminated. At 20$^{\circ}C$, control Tofu prepared from ozone treated-soybean was found to be spoiled after 72 hous. Titratable acidity and sensory changes of Tofu was increased as spoilage of Tofu was progressed, but pH was decreased at the first day of storage, and after that it was increased. At 30$^{\circ}C$, there was no remarkable difference between Tofu of control and Tofu prepared from ozone treated-soybean.

  • This study categorized and made considerations of the fermented soybean pastes into Meju, Chungjang, Si, mixed Jang, and other Jang in accordance with the manufacturing methods described in the fermented soybean paste section of Sangayorok (1450's), Suunjapbang (1540's) and Gyemiseo (1554). These are ancient cook books written in Chinese characters during the first half of the Joseon Dynasty. The content on the fermented soybean pastes recorded in these books included 24 items in Sangayorok, 11 items in Suunjapbang, and 14 items in Gyemiseo. In conclusion, the most important fermented soybean pastes during the first half of the Joseon Dynasty were those used to produce soy sauce-like seasoning for the purpose of a-chieving a salty taste with Meju made of soybeans as the main ingredient. The manufacturing techniques for such traditional fermented soybean pastes have been passed down through history to the present era.
