In this study, mulberry fruit juice was added with a salad dressing to compare and analyze the effect of different amounts of mulberry fruit juice(0, 10, 20, and 30%) and different breeds($Cheongilppong$ $and$ $Gwasang$ $2$) on the physicochemical qualities of salad dressing. As incresing of mulberry fruit juice added to, pH of the dressing decrease. Among the examined groups, $Gwasang$ $2$ were better than the others. Viscosity and sweetness of the dressing increased by the amount of mulberry fruit juice were added. DPPH radical scavenging activity of the control group was 15.60% while mulberry fruit juice salad dressing ranged from 19.73-50.83%. DPPH radical scavenging activity of $Gwasang$ $2$ group were higher than that of $Cheongilppong$ group. Color L and b value decreased as the amount of mulberry fruit juice added more, too value increase. The sensory property results showed that the salad dressing with 30% mulberry fruit juice was rated best. It was also preferred most. These results suggest 30% of mulberry fruit juice with $Gwasang$ $2$ are the best substitution ratio for salad dressing.

This study was conducted to find an efficient use for mulberry fruit powder (MFP). MFP was added to salad dressing products at concentrations of 0.25, 0.5, 0.75, 1%, and pH, total acidity, viscosity, color, and emulsion stability were measured and sensory evaluation was conducted. There were no significant differences among salad dressing samples regarding pH, total acidity and moisture content. Salad dressing made with 0.5% MFP showed significantly higher viscosity during storage and made the most stable emulsion. For color, the control sample had the highest L and b values, and these values decreased significantly as the amount of MFP in the sample increased. The control salad dressing had the lowest a value of -3.26, and this value increased significantly as the amount of MFP in the sample increased. Sensory evaluation of salad dressing was performed by a trained consumer panel. The flavor intensity increased as the amount of MFP increased in the salad dressing samples. Sweetness was rated significantly higher as the amount of MFP increased in the samples. The control sample had the lowest sourness and off-flavor, but there was no significant difference compared to the samples containing MFP.

This study was conducted to evaluate the consumers' preferences and perceptions on the salad and its dressings, via a total of 401 subjects in the Taegu area on the basis of 5-point Likert scale. Anthropometric data included the total subjects consisted of 66 females and 335 males: categorized by age, 20's (103), 30's (135). 40's (83), over 50's (80), The average size of family was 4.2 persons. According to BMI, 64.8% of the subjects belonged to the normal group. The age group that liked salad most was the 20's group, which was also the group that ate salad most frequently. The salad was perceived as food item which is convenient to eat(3.83), healthy(3.63), easy to prepare(3.73) and delicious(3.61) but rarely as a expensive item(2.44). The ingredients, used for salad preparation included fruits and vegetables(3.19) such as tomato and cucumber. Among the salad dressings, the fruit dressing was preferred the most(4.59), while the mayonnaise the least(3.59). The mayonnaise was perceived as an item with highest calories(4.1), and hardly perceived as a luxury item(2.78). The preference for the fruits dressing was highly correlated with the degree of education(p<0.05), age(p<0.001) and BMI(p<0.001). The higher the degree of education, the lower the level of age group, and the lower the BMI, the higher preference for the fruit salad dressing was demonstrated.

BACKGROUND: Organic fertilizers in watermelon cultivation are widely used to supply nutrient and organic matter. This study was conducted to investigate the effects of application rate of organic fertilizer on the watermelon growth and soil chemical properties in greenhouse METHODS AND RESULTS: The organic fertilizers used in this experiment were mixed expeller cake (MEC) and mixed organic fertilizer (MOF). The treatments were conducted with 4 levels (1.0 N, 0.7 N, 0.5 N and 0.3 N) on the basis of soil testing nitrogen fertilization (STNF) using MEC or MOF as the basal dressing, and using chemical fertilizers (CF) as the additional dressing on the rest of STNF. These fertilizations were compared to CF 1.0 N (0.3 N as the basal and 0.7 N as the additional dressing) and non fertilization (NF). The leaf area of watermelon in treatment 0.5 N and 0.3 N using MEC or MOF was similar to CF treatment. The absorbed nutrient amounts by leaf, weight and sugar contents of fruit in the 0.5 N and 0.3 N treatments were higher than other treatments. In 0.5 N and 0.3 N treatments using MEC or MOF on the basis of STNF, soil chemical properties such as electrical conductivity (EC), available $P_2O_5$ and exchangeable K concentrations after experiment showed tendency to decreasing or similar level before experiment. CONCLUSION(s): These results suggest that the MEC or MOF application as the basal dressing at the 30~50% level of STNF and CF application as the additional dressing on the rest of STNF be best to maintain adequate nutrient of soil and to increase marketable yield for watermelon.

This study was conducted to develop a salad dressing using jujube (Zizyphus jujuba Miller) puree and to evaluate the processing and quality characteristics of the salad dressing containing various amounts (0, 10, 20, 30, 40, and 50%) of jujube puree. Jujube puree was prepared by crushing peeled, deseeded and steamed fruit flesh. The dressing ingredients (jujube flesh puree, soy sauce, vinegar, oligosaccharide, olive oil, and water) were mixed, homogenized, and packaged in glass bottles. The quality characteristics (color property, total titratable acidity, soluble solids, viscosity, phenolic compound content, antioxidant activity, and sensory acceptability) of the dressing were analyzed. The lightness ($L^*$) and redness ($a^*$) of the dressing tended to increase as the amount of the jujube puree increased whereas the hue angle ($h^{\circ}$) decreased. The total titratable acidity, soluble solids, viscosity, phenolic compound content, and antioxidant activity of the dressing increased with the addition of more jujube puree. The sensory acceptability (color, smell, taste, texture, and overall acceptability) were significantly higher in the dressing added with 30% added jujube puree than in the other samples. The results show that jujube flesh puree (approximately 30%) can be utilized as an additive for preparing a dressing with simultaneously high antioxidant activity and acceptability.
