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.

The purpose of this study was to analyze the physiochemical properties of blackberry fruit beverage(BFB) and to develop a descriptive analysis procedure for evaluating the sensory characteristics of BFB. The amount of soluble solid, free sugar, pH, acidity, chromaticity, flavonoid, and anthocyanin of BFB were determined. All BFB samples demonstrated significantly different physicochemical properties(p<.01). Ten highly trained panelists identified the following eleven sensory attributes in the BFB and defined by standardized terminology for each attribute; turbidity, chromaticity for appearance characteristics, berry, grass, fermented, sweet, astringent, and sour for flavor characteristics, throat hit, refreshing, as well as astringent grade for textural characteristics. There were significant differences in all the eleven sensory attributes of the BFB samples(p<.001). Descriptive terminology used in the BFB analysis was capable of classifying the sensory attributes of the BFB. Based on these results, the analysis method and sensory evaluation techniques used in this study could be reasonably applied to other fruit beverages for establishing similar physiochemical characteristic and descriptive sensory attributes.

The principal objectives of this study were to analyze the physiochemical properties of four mulberry fruit beverages (MFBs) and develop descriptive analysis procedures for evaluation of their sensory characteristics. Soluble solid, free sugar, pH, acidity, chromaticity, flavonoid, and anthocyanin of MFBs were determined. All MFB samples showed significantly different physicochemical properties ($p$<0.01). Ten highly trained panelists identified the following 11 sensory attributes in the MFBs and defined the terminology for each attribute : turbidity, chromaticity for appearance characteristics, berry, grass, fermented, sweet, astringent, and sour for flavor characteristics, and throat hit, refreshing, and astringent for textural characteristics. There were significant differences in the 10 sensory attributes among the MFB samples ($p$<0.001). In color, the value of MFB3 was significantly higher than those of others ($p$<0.05). In taste and overall acceptance, the values of MFB2 were significantly higher than those of others ($p$<0.01, $p$<0.001). Descriptive terminology of the developed MFBs could explain the sensory attributes of the samples according to this result. Based on this, proper analysis and sensory evaluation techniques could be applied to other fruit beverages to establish their physiochemical characteristic and descriptive sensory attributes.

The purpose of this research was to appraise physicochemical properties by utilizing different Mit-sool, Juk, Seolgi-tteok, and Godubap, to produce traditional liquor. In all experimental plots, pH and amino acidity tended to increase with duration of fermentation. Titratable acidity displayed a very high number on the second day but then tended to decrease as fermentation progressed. Sugar contents were highest on the fourth day and tended to decrease with time. Alcohol content increased sharply at the initial stage of fermentation and increased gradually. On the 15th day, traditional liquor made with Godubap recorded the highest alcohol content. Common free sugar components were glucose and sorbitol. Common free organic acid components were lactic, succinic, citric, tartaric, malic, and acetic acids. Volatile flavor compounds were six alcohols, five esters, three aldehydes, and two ketones. Regarding overall acceptability in the sensory evaluation, traditional liquor using Seolgi-tteok as Mit-sool scored the highest. Overall, even though different types of Mit-sool had different physicochemical properties, there were no significant differences in volatile flavor compounds or sensory evaluation scores.

This study was carried out to investigate physicochemical properties of different concentrations (0.1%, 0.3%, and 0.5%) of red ginseng hydrolyzates (RGH)- or red ginseng extract (RGE)-added Asiago cheeses (AC) during ripening at $14^{\circ}C$ for 4 months. The moisture content significantly increased with increasing concentrations of both RGH- and RGE-added AC (p<0.05). While RGHAC and RGEAC were more yellow and darker with increasing concentrations than that of control (p<0.05), the color was not influenced from the hydrolysis. In texture analysis, hardness, cohesiveness, and chewiness of RGHAC and RGEAC significantly decreased compared to the control during the ripening (p<0.05). In sensory analysis, bitterness and ginseng flavor and taste scores increased significantly with increasing the concentrations of RGH and RGE during ripening (p<0.05). In conclusion, the addition of RGH and RGE into cheese slightly influenced the properties of Asiago cheese, and similarities were observed between RGHAC and RGEAC. Thus, the lower concentrations (0.1% to 0.3%) of RGH and RGE added to AC were preferred for color, texture, and sensory during the ripening, therefore, these cheeses would be worth developing commercially.

The seaweed Hizikia fusiformis is rich in protein, carbohydrates, vitamins, and minerals. We investigated the physicochemical properties and antioxidant activities of yanggaeng made with agar, sugar, honey, oligosaccharide, cooked white bean paste, and different amounts (0, 1, 2, 3, 4, and 5%) of H. fusiformis powder. The proximate composition, pH, sugar content, color, texture, antioxidant activity, and sensory properties of the yanggaeng were investigated. The moisture and sugar contents of the yanggaeng did not change despite increasing the amount of H. fusiformis. The pH decreased with increasing H. fusiformis. The lightness decreased significantly, whereas the redness and yellowness increased with increasing amounts of H. fusiformis. In the texture profile analysis, the hardness, gumminess, and chewiness decreased with increasing H. fusiformis content. The antioxidant activity of the yanggaeng increased with the concentration of the H. fusiformis powder. The yanggaeng containing 2% H. fusiformis had the highest overall sensory acceptance score. The addition of H. fusiformis to yanggaeng appears to improve its quality and antioxidant activity.

Baikseolgi was made with Kugija powder with the intention to take advantage of its functional properties. Appropriate amount of Kugija powder (0$\sim$8%) was mixed with rice flour, sugar, salt, and water and then, steamed for predetermined time and their physicochemical and sensory properties were measured. pH decreased significantly while titratable acidity increased significantly with the addition of Kugija (p<0.05). The addition of Kugija powder did not significantly affect the moisture content (p>0.05) although it appeared to decrease with the higher amount of Kugija. Lightness (L-value) decreased significantly with the addition of Kugija (p<0.05), indicating that the color of Baikseolgi became dark as also indicated by the visual observation. Redness (a-value) and yellowness (b-value), on the other hand, increased significantly as the amount of Kugija increased in the sample (p<0.05). Both hardness and firmness decreased significantly with the addition of Kugija (p<0.05). Eight percentage Kugija Baikseolgi was significantly stronger in Kugija flavor (7.9), chewiness (6.1), sweetness (5.0), and yellowness (8.2) attributes than other samples, whereas control was significantly higher in mouthfeel (6.0) and hardness (6.0) attributes than others (p<0.05). Finally, consumer test indicated that 4% Kugija sample received the highest score in appearance (8.13) and overall acceptability (8.07) attributes.

This study was conducted to compare the physicochemical and sensory properties of yogurt containing nanopowdered peanut sprouts (NPPS) and powdered peanut sprouts (PPS) at different concentrations (0.05-0.20%, w/v) during storage at $4^{\circ}C$ for 16 d. The pH values of NPPS (0.05-0.20%, w/v)-added yogurt were lower than those of PPS-added yogurt. The antiradical scavenging activity and LAB counts were significantly higher in NPPS-added yogurt than in PPS-added yogurt during the storage period of 16 d (p<0.05). Higher concentrations (0.15, and 0.20%) NPPS-added yogurt showed greater antiradical scavenging activity. The LAB counts were ranged from $9.00{\times}10^8$ to $1.10{\times}10^9$ and $1.30{\times}10^9$ to $9.10{\times}10^8$ CFU/mL in 0.05% and 0.20% NPPS-added yogurts, respectively. In sensory testing, 0.05 and 0.10% NPPS-added yogurt showed similar results to the control in whey-off, grainy texture, and overall acceptability. Yellowness and astringent scores increased with increasing addition of NPPS or PPS to the yogurt irrespective of its storage times. Peanut and beany flavors were lower during the storage for 0.05 and 0.10% NPPS-added yogurt. Based on the data obtained from the present study, it was concluded that 0.05 and 0.10%, w/v of NPPS could be used to produce NPPS-added yogurt without significant adverse effects on the physicochemical and sensory properties, but with an enhanced functional value added to the yogurt.
