  • In this study, salad dressing was prepared with added soypaste and its quality characteristics were evaluated. In terms of nutrient composition, the soypaste dressing contained higher levels of protein, minerals, and vitamins, and fewer calories, as compared to commercial mayonnaise. In addition, sensory evaluations revealed that the soypaste dressing received higher scores for flavor, taste, viscosity, and over-all preference than the commercial mayonnaise. The viscosity and emulsion stability of the freshly made soypaste salad dressing were 2,400 cP and 80%, respectively. And during 8 weeks of storage at $5^{\circ}C$, the viscosity and emulsion stability values remained similar to those of freshly made dressing. With prolonged storage time, the Hunter's color b-value slightly increased, whereas the L- and a-values slightly decreased. In terms of antioxidant activity, DPPH radical scavenging activity and lipid peroxidation inhibition were 2- to 3-fold higher in the soypaste salad dressing as compared to the commercial mayonnaise. And the soypaste dressing's antioxidant activity increased according to the storage temperature and time. Total microbial numbers increased to 6.2 log CFU/mL in the soypaste dressing, but E. coli was not detected. Overall, the results suggest that soypaste salad dressing could be introduced as a commercial product.

  • Purpose: This study aimed to prepare sea tangle vinegar and test its applicability as a vinegar-based functional salad dressing in terms of physicochemical properties. Methods: Sea tangle vinegar was prepared by mixing sea tangle with sugar and vinegar and fermenting the mixture at room temperature for 3 months. The resulting sea tangle vinegar was examined for its physicochemical properties and antioxidant activity with brewed vinegar and persimmon vinegar as controls. Results: The sea tangle vinegar showed significantly higher viscosity than control vinegars, and shear thinning behavior that is typical for salad dressing containing polymers. In addition, storage modulus (G′) of sea tangle vinegar was relatively high in dynamic viscosity measurement while that of control vinegars remained negligible. Together with the high soluble solids content of sea tangle vinegar, rheological behavior indicates that sea tangle vinegar had soluble polysaccharides extracted from sea tangle, consequently leading to an increase in viscosity. Titratable acidity (TA) and pH were 2.52% and 3.58, respectively, which satisfies the TA and pH requirements for microbiological safety of a salad dressing. Absorbance at 285 nm and Folin Ciocalteu's reagent method revealed that sea tangle vinegar contained antioxidative phenolic compounds. Conclusion: This study demonstrates that sea tangle vinegar could be potentially developed as a vinegar-based functional salad dressing when combined with sensory evaluation in the future.

  • This study was conducted to develop a novel salad dressing composite recipe composed of natural seasoning containing dried oak mushroom (Lentirus edodes). Dried oak mushroom (Lentirus edodes) has a better flavor and more nutrients than fresh oak mushroom since vitamins are activated during the drying process. To manufacture salad dressing with Lentirus edodes, dressing with 0%, 3%, 6%, 9%, and 12% added L. edodes were prepared and tested for quality. The pH of the dressing decreased with added L. edodes content, whereas acidity increased but decreased again in the 9% dressing. The L value decreased with added L. edodes content, whereas the a and b values increased but decreased again in the 9% dressing. Sugar content increased with added L. edodes. Rradish strength increased with added oak mushroom. Brittleness and chewiness decreased in the lower percentage dressing, increased in the 9% dressing, but decreased again in the 12% dressing. According to the sensory evaluation results, the highest overall acceptability was 3.3, in the 6% dressing compared to the control group.

  • This study aimed to determine the microbiological quality obtained by adding green tea extracts to prepare cook-chill foods. For this study, chicken meat salad was blended with green tea extracts at concentrations of 0, 2 and $3\%$ and prepared for a cook-chill system. The microbiological effects of green tea extracts were assessed during the production process by measuring process time, temperature, pH and Aw and by determining total plate counts and coliforms. The effects of green tea extracts on total plate counts and coliforms were observed during cold storage at $3^{\circ}C$ for five days. Green tea extracts improved the microbiological quality and showed antibacterial properties when added to chicken meat salad prepared in a cook-chill production system. The use of green tea extracts should be further explored as a means of enhancing freshness and quality in cook-chill foods.

  • The purpose of this study was to provide a basic resource for establishment of hygienic management standards for meal delivery from the central kitchen to schools. Flow diagrams for delivery of food were analyzed, and time-temperature conditions of the food and environment were measured. Four different foods samples including Mexican salad, radish salad, stir-fried pork and vegetables, and stir-fried chicken and vegetables were collected after production and before service. Microbiological analysis was performed for aerobic plate counts (APC), Enterobacteriaceae, coliforms, E. coli, Salmonella spp., S. aureus, B. cereus, C. perfringens, and L. monocytogenes. After completion of production of cooked foods 2~3 hours were taken for the cooked foods to reach the temperature danger zone. Food temperatures at the meal service did not meet the recommended temperatures ($10/57^{\circ}C$) for conventional school food service systems. The highest APC counts were observed in radish salad (5.70 log CFU/g), followed by Mexican salad (5.18 log CFU/g). Enterobacteriaceae and coliform counts were within acceptable levels of those recommended by the UK Public Health Laboratory Service. No E. coli or pathogens were found. These results provide useful information for determination of microbiological hazards in school food service systems, and suggest that time-temperature control during delivery is necessary for the safety of cooked foods.

  • The antioxidant activity of forty two kinds of salad vegetables grown in Korea was evaluated. Methanol extract of freeze-dried vegetable was assayed by radical scavenging activity using 1,2-diphenyl-2-picrylhydrazyl (DPPH) and Fe^{2+}$-catalyzed lipid peroxidation inhibition by TBA method. Total phenolics were determined colorimetrically using Folin-Ciocalteu reagent. The highest radical scavenging activity was expressed by perilla leaf, followed by dandelion leaf, red and green leafy lettuce, of which $IC_{50}$ was less than 0.10 mg/mL. Angelica leaf showed the highest inhibitory action for lipid peroxidation with $95\%$, and then dandelion leaf, water spinach, and perilla leaf inhibited over $80\%$. However, lettuce (Iceberg) and young Chinese cabbage exhibited the lowest antioxidant activity based on both assay methods. Highly positive correlations between antioxidative activities and total phenolics were observed (p < 0.001). The results suggested that salad vegetables, especially perilla leaf, leafy lettuce, dandelion or angelica, could be used for easily accessible sources of natural antioxidants.
