  • Effective way of cooking oil fire extinguishment is using water mist system which has cooling and smothering effects. Low pressure water mist system has advantage because it is compatible with existing sprinkler systems. To increase the effectiveness of low pressure water mist system, additives can be used which increase the momentum of water particle and the chemical effect. In this experiment, aqueous film forming form(AFFF) agent is used as additive and the effect of additive concentration and water pressure are experimented. For the extinguishment of cooking oil fire such as soybean and olive oils, AFFF agent is effective and can decrease the fire extinguishing time and water consumption.

  • In this study, we evaluated the physicochemical and sensorial properties of frozen Hanwoo beef patties prepared from prerigor and post-rigor muscle with soybean sauce or sodium chloride. The pH of the soybean sauce treatments was lower than the sodium chloride treatments (p<0.05); however, the Hanwoo patty prepared from pre-rigor muscle with soybean sauce had a lower cooking loss and smaller diameter than the Hanwoo patty prepared under the same conditions from post-rigor muscle (p<0.05). The addition of the soybean sauce inhibited lipid oxidation due to the antioxidative materials in soybean sauce such as melanoidin. The hardness of patties prepared from pre-rigor treatment was lower relative to those prepared from post-rigor muscle (p<0.05); however, there was no significant difference between springiness, cohesiveness, and chewiness (p>0.05). In the sensory evaluation, patties prepared from pre-rigor muscle with soybean sauce had a significantly high score in all traits (p<0.05); thus, pre-rigor muscle with soybean had the highest overall acceptability. Furthermore, the addition of soybean sauce to pre-rigor muscle produced similar effects as those observed for the addition of sodium chloride in regards to psychochemical properties. Moreover, meat products produced from pre-rigor muscle will have better antioxidative and sensorial properties.

  • The purpose of this study was to determine the optimal mixing conditions of soybean oil and bread crumbs mixture for pork patty. The experiment was designed according to the central composite design of response surface methodology. There were ten experimental points, including two replicates for soybean oil and bread crumbs. The physicochemical and mechanical analyses of each sample, including pH, cooking loss, thickness increase, moisture content, lightness, hardness, adhesiveness, springiness, chewiness, and gumminess showed significant differences (p<0.05). The results of sensory evaluation showed significant differences in tenderness, juiciness, and overall quality (p<0.05). The optimum formulation calculated by numerical and graphical method was 13.61 g of soybean oil and 6.35 g of bread crumbs. The results obtained in this study will be useful to the meat industry, which tends to decrease the saturated fatty acid content with a concomitant enrichment in the unsaturated fatty acids content.

  • To evaluate the possibility of low-salinity of traditional fermented food, we investigated quality characteristic of low-salted Yacon Jangachi using soybean sauce with sugar or vinegar for 50 days. Sugar content, titration acidity, and salinity of all Yacon Jangachi was increased as storage time increased. All of the Yacon Jangachi had less than 3.0% salinity. Especially, the salinity of the Yacon Jangachi with sugar and vinegar was the lowest during storage time. The L value was decreased as storage time increased but the results of the a and b values were reversed. Cutting force was not significant among samples and storage periods. In the results of sensory evaluation, preference of all samples were increased as storage time increased. The preference of color was not significant among samples from 30 days but the taste was reversed. The preference of flavor was significant between samples in 40 days, texture was not significant during storage time. Overall preference was not significant after 30 days, which suggested that Yacon Jangachi using soybean sauce retains overall preference in steady level from 30 days. Yacon Jangachi using soybean sauce showed the highest preference when produced with sugar and vinegar.

  • Doenjang(fermented soybean paste) was prepared by the series of processes including soaking, cooking, first fermentation(3 days at 30$\pm$2$^{\circ}C$) for the preparation of meju(soybean koji) after inoclulation of Aspergillus oryzae, and further fermentation (60 days at 30$\pm$2$^{\circ}C$) for the ripening after addition of salt 13% to meju. the crude phenolics extracted from defatted soybean and doenjang were fractionated onto the neutral phenolics(isofavonoids) and acidic phenolics(phenolic acids), respectively. Composition and antioxidative characteristics of phenolic fractions were determined. The neutral phenolic fractions contained genistin, genistein and daidzein; on the other hand, acidic phenolic fractions had syringic acid and seven other components. The content of genistin in doenjang dramatically decreased at the early stage of fermentation, whereas the content of genistein rather increased. In addition, the content of syringic acid of acidic phenolic fractions were increased during fermentation. These changes in individual phenolic components affected the antioxidative activity of neutral phenolics or acidic phenolics. antioxidative activity of phenolic compounds were evaluated during soybean fermentation. The antioxidative and free radical scavenging activity of neutral phenolic fractions and acidic phenolic fractions on linoleic acid autoxidation were also investigated.

  • Antioxidative characteristics of doenjang(fermented soybeans paste) phenolics on the lipid oxidation systems were studied by the determination of the oxidative related activity including lipoxygenase (LOX) inhibition, metal chelating and free radical scavengning of doenjang phenolics. Manlikong variety containing the highest amounts of phenolic compounds among the soybean variety, was used for doenjang processing. Doenjang was prepared by the series of processes including soaking for overnight, cooking for 1hr at 12Lb, first fermentation (3 days at 30$\pm$2$^{\circ}C$) for the preparation of meju(soybean koji) after inoculation of Asp. oryzae, and further fermentation(60 days at 30$\pm$2$^{\circ}C$) for the ripening after addition of salt 13% to meju. In order to investigate the antioxidative activity of phenolics in doenjang, the doenjang phenolics was extracted with methanol form freeze dried defatted doenjang. Antioxidative effects of methanol extract on linoleic acid oxidation system were observed by the significantly decreased levels of peroxide and conjugated diene formation. In addition, methanol extract resulted in the inhibition of LOX activity. and also, metal(FeCl$_3$) chelation and free radical scavengning activities were increased with increasing concentration of methanol extract.

  • 재래식 간장 및 된장 제조중에 일어나는 대두단백질 중의 lysine 가용도의 변화에 관하여 화학적 방법 및 생물학적 방법을 이용하여 측정하였으며 서로 다른 측정 방법에 의한 결과의 차이에 대하여 고찰 하였다. TLMI법에 의한 FDNB-reactive lysine의 동향을 보면 대두의 삶음과 메주 발효과정중 lysine의 가용도는 저하하나, 8개월간의 메주 장숙성과정에서 그 가용도가 다시 증가되어 원료대두 단백질중의 lysine가용도와 거의 같은 수준으로 되었다. 한편 백쥐의 사양시험에 의한 생물가 (BV), NPU, NER 및 상대적 lysine 가용율등에 의하면 메주 제조과정에서 뿐만 아니라 숙성과정중에도 lysine 가용도는 계속 저하되는 것으로 나타났다.

  • The aim of this study is to determine the effects of using emulsion manufactured with soybeans (ES) to substitute chicken breast in Vienna sausages. Four types of Vienna sausages (S1: 10% ES and 50% chicken, S2: 20% ES and 40% chicken, S3: 30% ES and 30% chicken, and S4: 40% ES and 20% chicken) for this study were made. The pH, color, proximate composition, sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE), microphotographs, cooking yields, and texture profile analysis of sausages were examined. The pH value of uncooked and cooked sausages increased significantly with increasing ES content (p<0.05). The crude protein contents of S2, S3, and S4 were significantly higher than that of the control (p<0.05). Furthermore, the SDS-PAGE results showed that α-conglycinin, β-conglycinin, and the acidic subunit of glycinin all increased with increasing ES content. Microphotographs revealed that increasing the ES content decreased the size of fat globules. The cooking yields of samples increased significantly with increasing ES content (p<0.05). The hardness values of ES treated samples were significantly lower than that of the control (p<0.05). Therefore, 30% substitute of chicken breast with ES can improve the quality and structure of Vienna sausage, without inducing critical defects.
