Abstract
The characteristics of sponge cakes prepared from various formulas having different types and levels of fat were examined through physical measurements and sensory evaluation. The physical properties of cake batters and cakes with hicook, that is, specific gravity and mixing characteristics of cake batters and volume of cakes, were similar to cakes with oil and added lecithin as emulsifier. Also in sensory evaluation the uniformity of air cell and moistness of cakes showed no significant differences in these samples. From this result, we concluded that lecithin is responsible for the characteristics of cakes with hicook. And hicook successfully replaced soybean oil in sponge cakes, and the fat content of cakes with hicook colud be reduced by 20% relative to cakes with soybean oils.

Abstract
The effect of time and amount of water by conventional blanching method on the retention minerals in spinach and broccoli was investigated. The vegetables were blanched for 1, 2, 3 and 4 minutes, with 150㎖, 300㎖, 450㎖ of water for every 100g of raw material. Blanching of spinach showed that Na was reduced remarkably after 2 minute of blanching, the others (K, Fe, Ca, Mg, P, Cu) were gradually decreased as the blanching time increased. Blanching of broccoli showed that the content of minerals were reduced remarkably after 1 minute of blanching. The longer blanching time further reduced the content of minerals. The retention of minerals (Na, K, Fe, Ca, Mg, P, Cu) in spinach and broccoli was reduced gradually as the blanching water increased. The retention rate of minerals were 12.7% of Na, 37.4% of K, 37.1% of Fe, 43.9% of Ca, 39.0% of Mg, 53.5% of P, 56.2% of Cu in spinach and 21.0% of Na, 41.3% of K, 57.8% of Fe, 38.8% of Ca, 51.5% of Mg, 57.7% of P, 44.4% of Cu in broccoli for 4 min, with water 450㎖ every 100g of raw material.

Abstract
This study is to seek methods for optimum management of foodservice system for elementary schools in Korea through surveying and analyzing the current status of the "common-management foodservice system` and certain important factors relating to its operations. For the survey of the current status of the "common-management foodservice system", questionnaires are prepared as against schools adopting "common-management system" ("Common Schools" ) as well as schools adopting "conventional management system" ("Conventional Schools" ) in Kyungsangbookdo ("Kyungbook" ) area. The survey items are composed of general items, items concerning tasks of dietitians, items concerning purchasing activities and items concerning level of recognition and job-satisfaction of the dietitians. Total 46 dietitans from Common Schools and 65 dietitians from Conventional Schools in Kyungbook region responded the questionnaires. The results of this study are as follows: 1. Information Concerning Dietitians Average age of the dietitians: 26.6 yrs Ratio of two years or less of experiences as school dietitian: Dietitians from Common Schools: 59.1% Dietitians from Conventional Schools: 50.8% 2. Types of the Foodservice In both schools, rural type are prevalent; however, between urban types and islands types, the ratio of urban types are larger than the ratio of islands types in Conventional Schools, and the opposite is true in Common Schools. 3. Decision of Suppliers The ratio of dietitian`s participaion in the decision making reaches only 38.3%, indicating the possibility of problems in quality control and hygienic aspects of the food supply. 4. Factor Analysis of the Foodservice Duties Food supply and general affairs administration work was carried out very well (4.2), while personnel management and operational improvement work (2.8), nutritional education work (2.3), and information related work were poorly carried out. No significant differences were found between the two types of the foodservice management systems. 5. Job Satisfaction scores of Dietitians Dietitians were more satisfied with the works (50.0), supervision (50.5) and co-workers (46.9) than pay (18.0) and promotion (22.3).

Abstract
The effect of low concentrations of ethanol (3-7%, v/v) in tryptic soy broth (TSB) as an antibacterial agent against Listeria monocytogenes was tested at -20, 5, 35, 45, 50 and 55℃. Increasing concentrations of ethanol progressively inhibited initial growth of L. monocytogenes at 35℃. Growth occured at 5% ethanol, but only after a prolonged lag period. The number of viable cells of L. monocytogenes declined during incubation at 7% ethanol. TSB containing 3-7% ethanol was inoculated with 10^5-10^6 cells/㎖ of L. monocytogenes and incubated at low temperatures (5℃, -20℃). In the presence of 3% of ethanol at 5 or -20℃, bacterial growth was inhibited more than 90% of control cells. TSB containing 3-7% ethanol was inoculated with 10^6-10^7 cells/㎖ of L. monocytogenes and incubated at high temperatures (45℃, 50℃, 55℃). Decrease in viability of the cells incubated at 45 or 50℃ was slow and the survival of L. monocytogenes was not affected so much in the presence of 3% of ethanol. The viability of L. monocytogenes was decreased with increasing concentration of ethanol and temperature. Decimal reduction times (D-values) based on tryptic soy agar plates at 55℃ were 20.1, 12.6, 7.4 and 4.2 min in 0, 3, 5 and 7% ethanol, respectively.

Abstract
This study was carried out to investigate the volatile constituents change according to extraction methods, parts and heating methods. The research results are as follows: 23 kinds of components were extracted by steam distillation method; 8 by head space method; 16 by ether extraction method; 9 by Tenax-GC. This fact indicated that volatile constituents differ depending upon the extracting method. When the volatile constituents were extracted by steam distillation method and analyzed by GC-MSD, the content of the volatile constituents was 41.71 ㎎% in the stem and 85.37 ㎎% in the leaf. A total of 23 components - 14 kinds of hydrocarbon, 5 of aldehyde, 4 of alcohol- were detected in the stem. A total of 31 components - 21 kinds of hydrocarbon, 5 of aldehyde, 4 of alcohol and 1 of ester were detected in the leaf. The leaf had comparatively more varied volatile constituents than the stem. In the stem, the octanal content was highest and the contents of limonene, sabinene, γ-terpinene and β-myrcene were higher; in the leaf, the content of octanal was highest and the contents of isobicyclogermacrene, limonene, β-farnesene, undecaethiol, γ-terpinene, sabinene, elemene, β-myrcene were higher. These were the major volatile constituents of the water dropwort. The volatile constituent formation changed as the water dropwort was heated. The volatile constituents of the water dropwort heated in 1000 ㎖ were the most similiar to those of the raw water dropwort, and volatile constituent content was highest.

Abstract
The antioxidant effects in soybean oil was investigated by browning reaction mixtures formed by sugar and reaction temperatures above 110℃. 0.1 M solution of xylose, glucose and sucrose were heated at 110, 120, 130, 140 and 150℃ for 24 hrs respectively. A reaction rate constant (k), activation energy (Ea) and Q_(10) value were determined by color intensity that was measured absorbance at 490 nm in each temperature. Soybean oil containing the ethanol extracts taken from the browning reaction mixtures that were heated at 110, 130 and 150℃ was stored in an incubator kept at 45.0±1.0℃ for 24 days. The results are as follows: 1. When 0.1M solution of xylose, glucose and sucrose were heated at 110℃ and 120℃, the intensity of glucose browning mixtures was the highest, but heated at 150℃, the color intensity increased in order of xylose > glucose > sucrose after 24 hrs. 2. The reaction rate constant (k) was increased rapidly above 140℃ and appeared maximum at 150℃, esp. xylose was the highest. The activation energy (Ea) of xylose was the highest as 93.28 Joule/mole and the Q_(10) value of xylose was appeared 1.28. Q_(10) value was also the highest in xylose. 3. The browning reaction mixtures that were heated at 110℃ appeared little antioxidant effects. But, in heated at 130℃ and 150℃, the antioxidant effects appeared in sucrose browning reaction mixtures. Therefore, in browning reaction mixtures that heated above 110℃, only sucrose browning reaction mixtures appeared antioxidant effects and xylose, glucose appeared little antioxidant effects. On the contrary xylose and glucose increased peroxide values of soybean oil.
