Lotus root, dried laver, and perilla leaf bugak, Korean traditional fried cuisine, were prepared with fermented glutinous rice batter and unroasted sesame oil or wheat flour batter and soybean oil and their physicochemical characteristics was evaluated. Bugak with fermented glutinous rice batter and unroasted sesame oil showed higher hardness, possibly brittleness than bugak with wheat flour batter and soybean oil. Oil absorption was higher in bugak with fermented glutinous rice batter and unroasted sesame oil than bugak with wheat flour batter and soybean oil, however, the lipid oxidation, evaluated by conjugated dienoic acid and p-anisidine values, was significantly lower in bugak with fermented glutinous rice batter and unroasted sesame oil. Frying oil strongly influenced the degree of lipid oxidation and fatty acid composition of bugak lipid. Different preparation of bugak did not show great effects on the contents of chlorophylls and carotenoids of dried laver and perilla leaf bugak, possibly due to protection by rice or wheat flour batter coating.

Soybean oil was stored in polyethylene for 12 weeks at $20^{\circ}C$. The influence of LED (light emitting diode) irradiation on four different wavelengths and fluorescent light was investigated. The pattern changes of volatile components in soybean oil was analyzed by electronic nose based on mass spectrometer. The obtained data from electronic nose were analyzed by discrimination function analysis. Under fluorescent light, the discriminant function first score (DF1) was significantly moved from positive position to negative one after 4-12 weeks. It means that the volatile compounds related to quality of lipid. It was shown to increase slowly due to green light of LED treatment, while blue and white LED light was influenced significantly as well as fluorescent light irradiation. Selection of LED irradiation would provide to keep good quality of soybean oil under distribution chain system.

The polyol was synthesized from soybean oil. Soybean oil was epoxized with peracetic acid, and was reacted with methanol in a sulfuric acid catalyst. OH value of synthesized polyol was 186(mg KOH/g). The polyurethane foam was synthesized with silicon type B-8409 as a surfactant, distilled water as a blowing agent, dimethylcyclohexylamine as a catalyst, and polymeric MDI. The density, the compressive strength, the compressive modulus, and the cell structure of the synthesized foam were investigated. The foam was prepared with changing the mole ratio of MDI, and the amount of water, surfactant, and catalyst. As the MDI index was increased, the density and the compressive property of the foam were increased.

The possibility of rapid non-destructive qualitative and quantitative analysis of vegetable oils such as perilla, com, soybean and rapaseed oils in sesame oils was evaluated. A calibration equation calculated by MPLS(Modified Partial Least Squares) regression technique was developed and coefficients of determination for perilla oil, com oil, soybean oil and rapaseed oil contents were 0.9992, 0.9694, 0.9795 and 0.9790 respectively. According to the data obtained from validation study, $R^2$ of contents of perilla, com, soybean, rapaseed oils were 0.997, 0.848, 0.957 and 0.968, and SEP of content of them 0.747, 5.069, 3.063 and 3.000 by MPLS respectively. The results indicate that the NIRS procedure can potentially be used as a non-destructive analysis method for the rapid and simple measurement of sesame oil mixed with other vegetable oils. The detection limits of the NIRS for perilla oil, com oil, soybean oil and rapaseed oil were presumed as 2%, $15{\sim}20%,\;15{\sim}20%$ and 10%, respectively.

The antioxidant actilvity of ethanol-extracts (M-2 and M-30), which had been obtained from a Maillard-type browning mixture after 2 and 90 hr browning, and BHA, BHT, TBHQ, and ascorbyl palmitate It·as investigated in soybean oil and soybean oil-water emulsion systems. The activity of the extracts and antioxidants was estimated by comparing the POV and TBA value development of the corresponding substrates with that of controls. The substrates and controls were stored at $45.0{\pm}0.5^{\circ}C$ for 25 days. The activity of the extracts (10 ml each) and antioxidants (0.02%) based mainly on the POY development of the corresponding anhydrous substrates was, in decreasing order, as follows ; As. palmitate, TBHQ > M-30, M-2 > BHT, BHA The actilvity of the extracts and antioxidants in tile oil-water emulsion substrates was, in decreasing order, as follows : As. palmitate > M-30, M-2 > BHT, TBHQ, BHA The activity of the extracts appeared to be more effective in the oil-water emulsion system than in the anhydrous system, and it f·as greater than that of the phenolic antioxidants such as BHA, BHT, and TBHQ in the oil-water emulsion system.

Product distribution and consumption in the military is difficult due to unique contracts and supply systems. It is difficult to change suppliers immediately when quality problem is encountered. Due to these special circumstances, the quality of products must be thoroughly controlled. Sesame oil is used to increase the taste and nutrition of food, but it is more expensive than other cooking oils. Oil producers may blend other cooking oils with sesame oil to make higher profits, so it has become important to identify good and bad products. In this study, pure sesame oil and blend oils were compared by analyzing their smell, taste, chemical components, and near infra-red spectra to determine quality differences between them.

Appropriate air quality in the pig building is essential to prevent farmers' health as well as to increase pig performance. This on-site experiment was conducted to assess dust reduction efficiencies of several liquid additives with spaying method in the enclosed pig building. The mean reduction rate of total dust only after spray was approximately 30% for all the treatments compared to initial level before spraying additives, which was found to reduce the initial level of total dust significantly (p<0.05). The mean reduction rate of all the treatments at 1hr after spray was about 24% which was 6% lower than only after spray. Since 3hr after spray, however, total dust level were fluctuated variably for all the treatments besides application of the soybean oil. Based on this result, effect of soybean oil on dust reduction in the enclosed pig building was most prominent among liquid additives evaluated in terms of efficiency and duration.

In this study, the attempts were made to Investigate the effect of squalene (200 ppm) on the autooxidation of soybean oil The effect of mixed tocopherols (200 ppm) was also studied In the same way and the results of the study were compared with those of squalene. A put of a commercial soybean oil was stored at 45.0$\pm$0.5t for their autooxidation. The extent of the autooxidation was estimated from the changes of the peroxide value and % conjugated dienoic acid content of the ell substrates The results of the autooxidation, squalene In the soybean oil substrate showed antioxidant activity but the activity was weaker than that of mixed-tocopherols nth the same concentration. The induction periods of the control and substrates with the same concentration. The Induction periods of the control and substrates with squalene and mixed-tocopherols were 448.5 504.9 and 668.9 hours, respectively. Time required to Tech a POV of 30meq/kg oil.
