To manufacture salad dressing with ginger, dressing with 0%, 3%, 6%, 9%, and 12% ginger added were prepared and tested for quality. The salad dressing products were evaluated for pH, acidity, chromaticity, salinity, sugar content, sensory test during storage up to 21 days at $4^{\circ}C$. The pH of the dressing increased with ginger added, whereas the acidity decreased(p<0.001). The L, a and b values increased during the storage period(p<0.01). Brix measurements decreased with ginger added, whereas the salinity increased. Also, the salinity of the dressing increased during the storage period(p<0.01). According to the sensory test results, dressing products with 9% and 12% ginger added were most preferred for the early storage days; however, the sensory test showed that the dressing with 6% ginger added was most preferred for seven test items according to storage period, indicating that the salad dressing added with 6% ginger was acceptable.

The of this study was to the abilities of Northeast Asians to discriminate sweetness on foods and their preference sweetness. Panels of Korean, Japanese and Chinese three sample -sucrose solutions, bulgogi, julienned radish salad- in which the sucrose levels had been manipulated to produce five samples of each. The sucrose solutions were prepared 1%, 3%, 5%, 7%, 9% sucrose to the water. Bulgogi and julienned radish salad 3%, 9%, 15%, 21%, 27% sucrose to the recipe. As, the three ethnic groups significant differences in test of sweetness in sucrose solutions(79%). Korean(a=1.164) to be the most sweetness, compared to Japanese(a=1.063) and Chinese(a=0.999). All ethnic groups preferred $3{\sim}7%$ solution, and Korean than Japanese and Chinese. Ethnic groups significant differences in sweetness of the julienned radish salad 21% sucrose. Korean(a=1.054) appeared to be the most able to detect the sweetness, compared to their Japanese(a=0.785) and Chinese(a=0.642). Both Korean and Japanese the strongest preference for the 15% julienned radish salad, the Chinese preferred the 21%. The abilities of ethnic groups to detect the sweetness in bulgogi significant differences high concentration(more than 27%), and the result of regression analysis on the awareness of sweet taste order Korean(a=0.918), Japanese(a=0.832), Chinese(a=0.690). All groups preferred the $9{\sim}21%$ bulgogi the most, Japanese showed higher preference 15% bulgogi than did Korean and Chinese.

15 vegetables were cooked as fresh salad, scalding, steaming, boiling, panbroiling, and hardboiling and retention of vitamin(A, Ascorbic acid, Niacin) and minerals(P, Fe, Mg, Ca, Na, K)were investigated about those cooks during making process. Vitamins were shown as the best retention in fresh salad, while as the worst retention in scalding vegetables. Minerals were determined as the best retention in panbroiled, while as the worst retention in scalding and boiling vegetables. In all vegetables cookings, the order of vegetables which had good retention of vitamins and minerals were doraji>perilla leaf, cabbage>k, radish, cucumber>chamchwi, lettuce> mungbean sprout>spinach, burdock, sedum>carrot, squash>soybean sprout>eggplant. Also Vit.A was kept high retention level in fresh salad, panbroiling, hardboiling, Niacin was remained in fresh salad, hardboiling, steaming, vegetables highly and AsA was kept high level in fresh salad only. And P in panbroiling, steaming, Fe in fresh salad, scalding, boiling, panbroiling, hardboiling, Mg in fresh salad, panbroiling, hardboiling, Ca in fresh salad, steaming, boiling, panbroiling, hardborling, Na in panbroiling, hardboiling and K in fresh salad pan, broiling, hardboiling were retained as high level.

The aim of this study was to investigate the effect of different light sources on the levels of glucosinolates (GSLs) in rocket salad (Eruca sativa L.). The light sources used in the study were: natural light (Control-1 or 2), red light-emitting diodes(LEDs), blue LEDs, mixed red and blue LEDs (R+B LEDs), white LEDs, fluorescent lamps (FL), and fluorescent lamps plus UV-C (FL+UV-C). Two separate experiments were conducted [Experiment I: Control-1, Red LED, Blue LED, Mix (R+B) LED and Experiment II: Control-2, White LED, FL, FL+UV-C] because of the limited number of growth chambers in our laboratory. The rate of increase in the length of rocket salad leaves was the highest under red LEDs and, FL confirming that red LED and, FL affect the growth of rocket salad. We separated and identified seven types of GSLs from the rocket salad:glucoraphanin, diglucothiobeinin, glucoerucin, glucobrassicin, dimeric 4-mercaptobutyl GSL, 4-methoxyglucobrassicin, and gluconasturtiin. The highest total GSL contents in Eexperiment I was found in plants grown under in red LEDs ($4.30{\mu}mol{\cdot}g^{-1}\;dry$ weight, DW), and the lowest under blue LEDs ($0.17{\mu}mol{\cdot}g^{-1}\;DW$). The highest total GSL contents in Experiment II was found in plants grown under FL ($13.45{\mu}mol{\cdot}g^{-1}\;DW$), and the lowest in FL+UV-C ($0.39{\mu}mol{\cdot}g^{-1}\;DW$). Especially in Experiment II, the content of dimeric 4-mercaptobutyl, which has a strong aroma and spicy flavor in rocket salad, was higher under FL and white LEDs than in Control-2, increasing by approximately 14.9 and 3.2-fold respectively. Therefore, light sources such as red LEDs, white LEDs and FL affected the accumulation of GSLs in rocket salad.

To evaluate the storage characteristics of pheasant meat products, contents of aerobic, anaerobic and food poisoning bacteria as well as VBN were measured during storage at various temperatures. 1. During the storage Escherichia coli and food poisoning bacteria including Salmonella, Shigella and Staphylococcus were not detected from any of the pheasant meat products. 2. Total plate counts of aerobic and anaerobic bacteria increased with storage temperature, showing more than $10^6CFU/g$ of most pheasant meat products within 5~10 days of storage at $20^{\circ}C$ and $30^{\circ}C$. However, frank sausage, loin ham, pressed ham and salad showed less than $10^5CFU/g$ in 20~30 days of storage at $20^{\circ}C$. 3. When stored at $10^{\circ}C$, smoked product, electric roasted product and pressed ham showed the bacterial counts of more than $10^4CFU/g$ within 10 days of storage. Frank sausage, loin ham and salad, however, showed less than $10^3CFU/g$ in 10 days of storage at $10^{\circ}C$. 4. VBN contents of smoked product, electric roasted product and frank sausage exceeded edible limit of 20 mg%, showing more than 40 mg% and 80 mg% within 5 days and 10 days, respectively, of storage at $10^{\circ}C$. In contrast, loin ham, pressed ham and salad had the VBN of less than 20 mg% in 10 days of storage at $10^{\circ}C$. In summary, while pheasant meat products in general appear to be prone to microbial growth, loin ham and salad are thought to have a longer storage period than others, showing about 10 days of preservation at $10^{\circ}C$. Products other than loin ham and salad are suggested to be stored frozen or refrigerated at below $10^{\circ}C$.

The issue of safety and quality of cooked food served at foodservice institutions has brought more attention to food scientists because the foodservice system is growing and becoming more popular in Korea. In order to control the quality and safety of cooked foods, the production and holding methods of foods should be carefully studied and the implications considered by the foodservice industry. Therefore, studies on microbiological, nutritional, physicochemical and sensory quality are essential in this area. The purpose of the present study was to evaluate the chemical and microbial qualities of salads during holding. Several holding temperatures in the range of 5∼26$^{\circ}C$ were used for holding. Chicken salad and ham ＆ cucumber salad exceeded the standard after 30min of room temperature holding after preparation. Quality deterioration increased at higher holding temperatures, which suggested that refrigerator holding is the most desirable.

To evaluate the antibiotic resistance of Enterococcus from salad and sprout, Enterococcus were isolated and identified from 47 salad samples and 37 sprout samples, and then their antibiotic resistances were analyzed. Ninety five Enterococcus, 41 strains from salad and 54 strains from sprout, were ultimately isolated. The frequent Enterococcus in salad and sprout were E. gallinarum, E. faecalis, E. faecium, E. hirae, and E. avium. Minimum inhibitory concentrations of the isolates for vancomycin were below $4{\mu}g/mL$, which were not high levels of resistance. All Enterococcus proved to be resistant to streptomycin and chloramphenicol. Twenty two percentage of the isolates were resistant to penicillin, however, almost the isolates were sensitive to tetracycline. Eighteen percentage of the isolates were resistant to erythromycin. All E. faecium and E. faecalis were found to be ampicillin-resistant, and seven E. faecalis and five E. faecium were resistant to rifampicin. Overall antibiotic resistances of Enterococcus isolates were relatively low and low resistance to vancomycin was similar to those evidenced by Enterococcus isolated from the other foods. Therefore, there may be no special risk from the antibiotics resistances of Enterococcus and especially vancomycin-resistant Enterococcus from the fresh-cut salads and the sprouts.

The effects of spirulina-added salad dressing on lipid profiles and antioxidant biomarkers such as total glutathionine, TBARS value, carbonyl value, GPx, GR, SOD and paraoxonase activity in plasma or liver of mice were evaluated Sixteen male ICR mice weighing 20$\pm$2 g were divided into two groups and fed low fat ($5\%$ fat) diet (low fat control: LFC) and low fat control plus dressing diet (LFD) for eight weeks. Body weight, tissue weights of liver, heart and kidney, and the distribution of body fat deposition were not significantly different between two groups. Also, the profile of TG, TC, LDL and HDL cholesterol were similar between two groups. The DNA damage was determined using the comet assay (single cell gel assay) with alkaline electrophoresis and quantified by measuring tail length (TL). Spirulina salad dressing consumption resulted in significant decrease in lymphocyte DNA damage expressed by TL (LFC: $28.8{\mu}m$, LFD: $20.3{\mu}m$). Additionally, salad dressing consumption for 8 wks decreased the lipid peroxidation assayed by TBARS to $12.6\%$ compared with the control. The levels of antioxidant vitamins such as $\beta$-carotene were significantly higher in plasma of LFD group than those in LFC group based on HPLC method This study shows that spirulina-added salad dressing exerts degenerative disease-protective effects on oxidative DNA damage and lipid peroxidation possibly via a free radical levels.
