  • It was investigated to study the sensory and physicochemical properties of chicken consomme made with different boiling time(1, 2, 3, and 4 hr). The sensory properties were evaluated with respect to both the acceptability (color, smell, mouthfeel, taste, overall acceptability) and intensity characteristics (color, smell, clarify, taste). From the results, the 3hr treatment was most favored for smell, mouthfeel, taste and overall acceptability, from the sensory evaluation tests. According to a quantitative descriptive analysis of the sensory evaluation for the treatments, the color and smell showed higher scores by increasing the boiling time. Whereas, in clarify and taste, the 3hr treatment showed the highest values. As for the physicochemical characteristics, the pH was increased with increasing boiling time. The reducing sugars, turbidity and viscosity increased with increasing boiling time. The colorimetric lightness values L decreased, and redness a, yellowness b and color difference values ΔE increased with increasing boiling time. There were 18 free amino acids indentified ; the glutamic acid, alanine, arginine and lysine were high in the free amino acid of the chicken consomme made with different boiling times. There were 3 free sugar indentified, glucose, fructose and sucrose. The free amino acid and free sugars contents increased with increasing boiling time. There were changes in the mineral contents of the chicken consomme made with different boiling time ; with high K, Na, P, Mg, Ca and Fe contents. The mineral contents increased with increasing boiling time. Especially, the 3hr treatments was more highly increased than rest of the treatments in all characteristics. The results showed the chicken consomme made by boiling far 3hr was the most preferably in the sensory and physicochemical quality.

  • Objective: A study was conducted to develop non-dairy creamer analogs/mimics using egg white, egg yolk, soy protein and their combinations, and their nutrient content, shelf-life and flavor acceptability were compared. Methods: Spray dried egg white, egg yolk, and soy protein isolate were purchased from manufacturers and used for the formulae. Results: The protein contents of the non-dairy creamer analogs/mimics were about 8.5% as calculated. The amounts of oleic and linoleic acid content increased as the amount of yolk increased in the formula, but the increases of polyunsaturated fatty acids were <0.5% of total fat. Addition of egg yolk to the formula increased choline and lutein content in the products, but the amounts were <0.4 mg/g for choline and $4{\mu}g/g$ for lutein. The lutein in the products continued to decrease over the storage time, and only about 15% to 20% of the 0-month amounts were left after 3 months of storage. Although the thiobarbituric acid reactive substances values of the spray-dried non-dairy creamer analogs/mimics increased as storage time increased, the values were still low. Yellowness, darkness, and egg flavor/odor of the non-dairy creamer analogs/mimics increased as the amount of egg yolk in the formula increased. The overall acceptability of the non-dairy creamer analogs/mimics was closely related to the intensity of egg flavor/odor, but storage improved their overall acceptance because most of the off-odor volatiles disappeared during the storage. Water temperature was the most important parameter in dissolving spray-dried non-dairy creamer analogs/mimics, and $55^{\circ}C$ to $75^{\circ}C$ was the optimal water temperature conditions to dissolve them. Conclusion: Higher amounts of yolk and soy protein combinations in place of egg white reduced the cost of the products significantly and those products contained better and balanced nutrients than the commercial coffee creamers. However, off-flavor and solubility were two important issues in the products.

  • The aim of this study was to determine the optimum amount of apricot seed powder to add to rice flour in oder to prepare Sulgidduk (traditional rice cakes). As the apricot seed powder level of the Sulgidduk increased, the moisture contents of the samples decreased (40.30~43.46%), and the color of L- and a-values also decreased, while the b-value increased. According to instrumental test results, hardness, springiness, gumminess, chewiness and adhesiveness were all highest in the 0% apricot seed powder sample. The cohesiveness of samples did not show a conclusive relationship with the level of apricot seed powder present. In sensory evaluation results, the 3% and 6% samples received high overall acceptability scores. In conclusion, based on both sensory and instrumental testing, the optimal Sulgidduk mixture consisted of 3~6% apricot seed powder added to rice flour.

  • This study aimed to determine the sensory acceptability of Gochujang dressing containing added Maesil (Prunus mune) concentrate. Gochujang dressing was blended with different concentrations of Maesil concentrate (0%, 1%, 2%, 3%, 4%). Moisture contents, L, a, b values, pH level, and sugar contents decreased, whereas acidity and viscosity increased with increasing Maesil contents. Salinity did not change significantly. For attribute difference test, as Maesil concentration increased, color intensity, savory flavor, sour flavor, hot taste, and mouthfeel decreased, whereas glossiness decreased. The acceptance test showed that 2% Maesil concentrate was the most preferable for appearance, taste, texture, and overall quality. In conclusion, the results indicate that addition of 2% Maesil concentrate to Gochujang dressing is optimal and provides good properties as well as reasonably high overall acceptability.

  • This study was performed to develop Cnidium officinale-flavored oils. Cnidium officinale is one of the Korean aromatic medicinal plants. The flavor patterns of Cnidium officinale-flavored oils during storage were detected by using an electronic nose with 6 metal oxide sensors, and a principal component analysis (PCA) was carried out. The overall acceptability of flavor and the masking effects on fetid smell of beef of Cnidium officinale-flavored oils were investigated by sensory evaluation. In COI-flavored oil, flavor patterns between the storage samples for 1 week and 16 weeks could be distinguished. And in CO II-flavored oil, flavor patterns between the samples stored for 1 week and 8 weeks and the flavor patterns between the samples stored for 1 week and 16 weeks in CS I-flavored oil could be distinguished. In CS II-flavored oil, flavor patterns of the samples stored for 1, 4, and 8 weeks also could be distinguished. Fetid smell in beef was significantly reduced by the addition of COI- and CS II-flavored oils. As the storage time increased, overall acceptability of Cnidium officinale-flavored oil decreased, indicating that Cnidium officinale-flavored oils were most preferred at 8 weeks of storage.
