The objectives of this study was to determine the oil contents and fatty acid compositions of soybean germplasms including major Korean cultivars, and to provide the basic information of fatty acid composition for development high quality soybean varieties. Among 46 Korean major cultivated soybean samples, the oil contents were varied from 15.8% to 20.3%, and the average oil content was 18.2%. Crude oil content of cv. Saebyolkong (20.3%) was the highest among that of other cultivated soybeans. Likely many other oils of plant origin, most fatty acids in soybean are unsaturated. The highest percentage of fatty acid in soybean was linoleic acid (18:2), followed in a decreasing order by oleic (C18:1), palmitic (C16:0), linolenic (C18:3), and stearic acid (C18:0). The composition of C18:1 and C18:2 fatty acids among 563 soybean germplasms and cultivars which were positively correlated with nutritional quality of edible vegetable oil, were ranged $13.29{\sim}43.30%\;and\;38.21{\sim}61.51%$, respectively, and the C18:3 which were negatively correlated with flavor quality were varied from 5.03% to 11.48%. Also, the composition of C16:0 and C18:0 which were known to raise total cholesterol levels in human serum were ranged $8.50{\sim}14.78%\;and\;1.86{\sim}4.78%$ respectively. On the other hand, the range of fatty acid composition among 46 Korean major soybean cultivars has been investigated to be: C16:0, $8.96{\sim}13.23%$; C18:0, $2.55{\sim}4.20%$; C18:1, $16.33{\sim}36.41%$; C18:2, $42.32{\sim}58.84%$; C18:3, $6.98{\sim}10.72%$. Among the 563 germplasms tested, there are significant correlations among unsaturated fatty acids: negative between C18:1 and C18:2 (r=-0.961**) or C18:3 (r=-0.756**), and positive between C18:2 and C18:3 (r=0.608**). Also, the C18:1 was negatively correlated with saturated fatty acids, C16:0 (r=-0.231**) and C18:0 (r=-0.479**).

A total of 100 commercially available olive oil products were analyzed for 179 pesticide residues using gas chromatography-tandem mass spectrometry (GC/MS/MS). The olive oil samples were mixed with organic solvents, centrifuged and frozen to remove fat, and pesticide residues were analyzed using the "quick, easy, cheap, effective, rugged, and safe" (QuEChERS) method. The determination coefficient (R²) of the analysis method used in this study was ≥0.998. The detection limit of the method ranged 0.004-0.006 mg/kg and its quantitative limit ranged 0.012-0.017 mg/kg. The recovery rate (n=5) measured at the level ranging 0.01-0.02, 0.1, and 0.5 mg/kg ranged 66.8-119.5%. The relative standard deviation (RSD) was determined to be ≤5.7%, confirming that this method was suitable for the "Guidelines for Standard Procedures for Preparing Food Test Methods". The results showed that a total of 151 pesticides (including difenoconazole, deltamethrin, oxyfluorfen, kresoxim-methyl, phosmet, pyrimethanil, tebuconazole, and trifloxystrobin) were detected in 64 of the 100 olive oil products. The detection range of these pesticide residues was 0.01-0.30 mg/kg. The percentage acceptable daily intake (%ADI) of the pesticides calculated using ADI and estimated daily intake (EDI) was 0.0001-0.1346, indicating that the detected pesticides were present at safe levels. This study provides basic data for securing the safety of olive oil products by monitoring pesticide residues in commercially available oilve oil products. Collectively, the analysis method used in this study can be used as a method to analyze residual pesticides in edible oils.

This study was performed to determine the effect of temperature condition on growth of juvenile abalone Haliotis discus hannai with the different feeds. Two types of feed (dry sea tangle and experimental diet) at water temperatures of 20 and $23^{\circ}C$, and 23 and $26^{\circ}C$ were applied to experimental abalone twice. Forty-five juvenile abalone averaging 10.1 g in the first feeding trial and 11.5 g in the second feeding trial were randomly stocked into 6 of 50 L plastic rectangular containers each. Fishmeal, soybean meal and shrimp head meal was used as the primary protein source in the experimental diet. And dextrin and wheat flour, and soybean oil were used as the primary carbohydrate and lipid sources in the experimental diet, respectively. The dry sea tangle and experimental diet were fed to abalone once a day at the ratio of 1.5-2.0% total biomass of abalone with a little leftover in each experimental condition. Weight gain of abalone was significantly affected by feed type, but not by water temperature in the first feeding trial. Regardless of water temperature, weight gain of abalone fed the experimental diet was significantly higher than that of abalone fed the dry sea tangle. However, weight gain of abalone was significantly affected by water temperature, but not by feed type in the second feeding trial. Weight gain was highest in abalone fed the experimental diet at $23^{\circ}C$, followed by abalone fed the dry sea tangle at $23^{\circ}C$, abalone fed the experimental diet and dry sea tangle at $26^{\circ}C$, which was lowest. Moisture and crude protein content of the edible portion of abalone was significantly affected by feed type, but not by water temperature in the second feeding trial. However, ash content of the edible portion of abalone was significantly affected by water temperature, but not by feed type. In considering these results, it can be concluded that the well formulated feed was superior to the dry sea tangle for growth of juvenile abalone, and water temperature conditions of 20 and $23^{\circ}C$ seemed to be better than $26^{\circ}C$ to improve weight gain of abalone.

Insects are gaining recognition as an alternative source of protein. As a result, more and more domestic farms have begun mass rearing of edible insects. In order to produce high quality insects, studies on the development of safe and nutritious feed sources are needed. Given the cost of rearing insects, agricultural and industrial by-products are good sources for feed. The efficient utilization of these by-products can help in reducing the cost of production and preventing environmental pollution. In the current study, Citrus unshiu peel (CP), soybean curd cake (SCC), soybean oil meal (SOM), and brewers dried grain (BDG) were investigated for their effects on larval growth and development of Protaetia brevitarsis. Interestingly, the feed with 10% SCC increased larval weight by 3.5 times. For the larval period, the group of 10% SCC was significantly shorter than the control. Furthermore, minerals such as Zn, Ca, K, Mg, Na, and P were recorded to be high in 10% SCC. A total of 17 amino acids were present in 10% SCC, of which tyrosine and arginine were predominant. The heavy metal contents were very small amounts or not detected in any of the investigated groups. These findings provided a scientific basis for the utilization of soybean curd cake as a nutritional feed source to promote larval growth and produce quality insects.
