In this paper, the differences between Korean and Japanese ways of seasonings are studied. The main results are summarized as follows: (1) Shouyu and Miso which are Japanese equivalents of soy sauce and bean paste of Korean foods are used in variety of different seasonings with some other ingredients while Korean counter parts are used only to add salty tastes. (2) Shouyu and Miso lose their flavors after considerable time of heating, while Korean soy sauce and bean pastes increase their tastes after heating. (3) Mirin adds sweety taste and glaze and Sake makes food soft or hard according to the moment of being added during cooking. (4) In Korean foods soy sauce, bean paste and red pepper paste are on the basis of tastes, Dashi is used in almost every Japanese food. (5) Seasoned vegetables of Korean food are prepared only with spices of green onion, garlic and sesame oil while seasoned fishes or vegetables are mixed with Shoyu or salt and vinegar in Japanese food. (6) In making Zorim, Korean traditional sauces are added from the beginning of heating. But in making Nimono, sugar, salt, vinegar, Shoyu and artificial taste are added in order during heating. (7) In grilling, main food for grilling in Korea is meat, which is prepared with a variety of spices such as soy sauce or/and red pepper pastes, garlic, green onion, sesame oil, sesame powder, pepper and sugar while mainly fishes are grilled with salt, occasionally with Shoyu or Miso in Japanese food. (8) Pan frying fishes are taken with soy sauce with vinegar in Korea but Tepura are eaten with Tentsuyu in Japan.

Physicochemical and sensory characteristics of Yukwa(fried rice cookie) made by different processing condition were investigated to estabilish the optimum expansion of Yukwa. The expansion rate and crispness of Yukwa prepared by soaking waxy rice for 24 hours was satisfactory . Addition of 15% soy slurry gave better effect on increasing the expantion rate, crispiness and sensory preference than no addition of soy slurry . Yeast, Soju(distilled liquor) , Mackeali(rice wine, turbid) and Chunju(rice wine, clear) as expansion reagent were added to Yukwa prepration . Yeast and Mackeali among tested expansion reagent showed better expansion rate and lower hardness meausred by texturometer than Chunju. Yukwa added chungju showed more fine structure and lower expantion rate than others. Microwave puffed Yukwa was less expansion rate, but same level of crispiness and hardness compared with oil puffed. And no difference in sensory characteristics such as degree of crispiness and stickiness of microwave puffed and oil puffed.

This study was performed to observe how soy protein and calcium in rats fed unsaturated fat-enriched diet affect the total lipid and cholesterol contents of blood and tissues male Sprague-Dawley rats weighing approximately 220g were fed four purified diets which contained 18% (w/w) corn oil, 1% (w/w) cholesterol, two sources of protein : casein or isolated soy protein (ISP) and two levels of dietary calcium : 0.1% or 1.0%, first for four weeks (Expt. 1) and second for eight weeks (Expt. 2). The contents of total lipid, cholesterol and triglyceride in blood, liver, heart and feces were determined. After four weeks feeding, the serum lipid and cholesterol concentration was not significantly different among the groups. After eight weeks feeding, these concentrations were significantly lower in ISP-High calcium group. The serum lipid concentration was influenced by dietary protein sources and calcium levels. These results indicated that the hypolipidemic effects of soy protein and high calcium intake were partly due to decrease in lipid absorption and these effects were not detected at 4 weeks feeding but 8 weeks feeding.

Soybean [Glycine max(L.) Merr.] oil is versatile and used in many products. Modifying the fatty acid profile would make soy oil more functional in food and other products. The ideal oil with the most end uses would have saturates(palmitic + stearic acids) reduced from 15 to < 7%, oleic acid increased from 23 to > 55%, and linolenic acid reduced from 8 to < 3%. Reduced palmitic acid(16:0) is conditioned by three or more recessive alleles at the Fap locus. QTLs for reduced palmitic acid have mapped to linkage groups(LGs) A1, A2, B2, H, J, and L. Genes at the Fad locus control oleic acid content(18:1). Six QTLs($R^2$=4-25%) for increased 18:1 in N00-3350(50 to 60% 18:1) explained four to 25% of the phenotypic variation. M23, a Japanese mutant line with 40 to 50% 18:1 is controlled by a single recessive gene, ol. A candidate gene for FAD2-1A can be used in marker-assisted breeding for high 18:1 from M23. Low linolenic acid(18:3) is desirable in soy oil to reduce hydrogenation and trans-fat accumulation. Three independent recessive genes affecting omega-3 fatty acid desaturase enzyme activity are responsible for the lower 18:3 content in soybeans. Linolenic acid can be reduced from 8 to about 4, 2, and 1% from copies of one, two, or three genes, respectively. Using a candidate gene approach perfect markers for three microsomal omega-3 desaturase genes have been characterized and can readily be used in for marker assisted selection in breeding for low 18:3.

Purpose: While rapeseed oil, soy bean oil, palm oil and waste cooking oil are being used for biodiesel, the viscosity of them should be lowered for fuel. The most widely used method of decreasing the viscosity of vegetable oil is to convert the vegetable oil into fatty acid methyl ester but is too expensive. This experiment uses ultrasonic energy, instead of converting the vegetable oil into fatty acid methyl ester, to lower the viscosity of the waste cooking oil. Methods: For irradiation treatment, the sample in a beaker was irradiated with ultrasonic energy and the viscosity and temperature were measured with a viscometer. For heating treatment, the sample in a beaker was heated and the viscosity and temperature were measured with a viscometer. Kinematic viscosity was calculated by dividing absolute viscosity with density. Results: The kinematic viscosity of waste cooking oil and cooking oil are up to ten times as high as that of light oil at room temperature. However, the difference of two types of oil decreased by four times as the temperature increased over $83^{\circ}C$. When the viscosity by the treatment of ultrasonic energy irradiation was compared to one by the heating treatment to the waste cooking oil, the viscosity by the treatment of ultrasonic energy irradiation was lower by maximum of 22% and minimum of 12%, than one by the heating treatment. Conclusions: Ultrasonic energy irradiation lowered the viscosity more than the heating treatment did, and ultrasonic energy irradiation has an enormous effect on fuel reforming.

This study was carried out to determine the best mixing ratio of French dressing containing onion juice which was added at with different levels (12, 24, 36, and 48%). The mixing methods of ingredients were evaluated through sensory evaluation and viscosity and color of were measured. Instead of soy bean oil, we also studied various oils(corn oil, grape seed oil, canola oil, and olive oil) for the purpose of determining functional French dressing. The results were as follows; The results of the sensory evaluation showed that the French dressing with 36% added with 36% onion juice was the preferred most in appearance, flavor, and overall preference. Correlation coefficients between overall preference and sensory characteristics of onion added French dressing were higher in the order of taste (r=0.64), flavor (r=0.54), texture (r=0.48), appearance (r=0.41). The quality of French dressing varied greatly depending on the mixing methods of ingredients. The best method for making dressing was mixing 5 mL of oil with the other ingredients at 5 seconds intervals. The results of the sensory evaluation on French dressings with added onion juice containing soybean oil, corn oil, grape seed oil, canola oil, and olive oil, indicated that soybean oil was the most preferable. The appearance and taste of French dressing containing soybean oil were significantly the highest with regard to preference.

본 연구는 식물성 지방급원이 당뇨모델의 지질대사에 미치는 영향을 검토하고자 수행하였다. 실험 모델은 STZ의 투여로 유발된 인슐린의존형 당뇨 마우스를 이용하였고, 4종류(라아드 10%에 각각 대두유, 쌀눈기름, 쌀겨 기름, 참기름 10% 첨가)의 실험식이를 7주간 급여하여 체내 지질 함량 및 대변으로의 배설량을 조사하였다. 그 결과 실험동물의 식이섭취량과 체중 및 장기 무게는 실험군 사이에 큰 차이가 없었으나, 혈청 중성지방은 쌀눈기름 및 쌀겨기름 첨가군에서 다른 실험군들보다 낮은 경향을 보였고, 간의 총콜레스테롤 함량은 쌀눈기름 첨가군에서 대조군보다 낮은 경향을 보였으며, 간의 총지질 함량도 쌀눈기름 첨가군에서 대조군보다 낮은 경향을 보였다. 그리고 대변으로의 총지질 및 총콜레스테롤 배설량은 쌀눈기름 첨가군과 쌀겨기름 첨가군에서 대조군인 대두유군보다 유의하게 많은 것으로 나타났다. 이상의 결과로부터 쌀눈기름과 쌀겨기름 급여군에서 체내 지질 함량이 낮았고 쌀눈기름군에서 쌀겨기름군보다 낮은 경향을 보였다. 그러므로 쌀눈기름은 인슐린의존형 당뇨마우스에서 체내 지질 함량 저하 효과가 있는 것으로 밝혀졌으며, 이는 쌀눈기름의 대변중 총지질 및 총콜레스테롤 배설량 증가와 관련된 것으로 평가되었다. 따라서 쌀눈기름은 대두유나 참기름보다 당뇨병 모델의 체내 지질대사에 개선 효과가 있는 것으로 보인다.
