  • The acceptability of purified stevioside as a sweetner was carried out. The content of stelvioside was $7.30{\sim}17.8%$ of the dry leaf of stevia harvested in Korea and the purified stevioside showed $100{\sim}150$ folds sweeter than sucrose. Improvement of acceptability of the purified stevioside by mixing with other sweetners was as the following order: sucrose>glucose>fructose= invert sugar >saccharin-Na. When 2 kinds of sweetner were mixed stevioside the improvement was the same as one sweetner was mixed with stevioside. The mixture of the stevioside and sodium chloride did not give any off-taste.

  • The objective of this study was to determine effects of soybean oil(SO), cottonseed oil(CO) and ricebran oil(RO) on stability and flavor of yackwa. This study consisted of yackwa fried in 3 differnet oils, then stored for 0, 3, 6 weeks in normal wrap at room temp. or vaccum package at $4^{\circ}C$. The moisture, oil contents, Hunter color values(L, 'a' and 'b'), % free fatty acid(FFA), thiobarbituric acid(TBA) value and sensory scores for color, flavor and acceptability were analyzed. The foam height of the oil after frying was also determined. Yackwa fried in RO was more red('a'=11.43) than yackwa fried in SO(10.64) or CO(10.51). TBA value of yackwa showed no difference among frying oils. Yackwa fried in SO showed better acceptability than those fried in CO. Yackwa fried in RO showed similar acceptability to yackwa fried in SO. The % FFA and TBA value of yackwa averaged across oil and package showed increasing tendency during 6 weeks storage.

  • Europeans are much more rigid in their thinking on robots and especially have a negative view on robots as peers since they regard robots as labor machines. Recently, Korea invented several educational robots as peer tutors. Therefore, study was needed to determine the difference in cultural acceptability for educational robots between Korea and Europe (Spain). We found that Europe seems to be much more rigid in its thinking on robots and especially has a negative view on educational robots. Korean parents have a strong tendency to see robots as 'the friend of children,' while on the other hand, European parents tend to see educational robots as 'machines or electronics'. Meanwhile, the expectation of children on educational robots showing identification content was higher in Europe than in Korea since European children are familiar with costume parties. This result implied that we may find a Korean market for educational robots earlier than a European market, but European children will be eager to play with educational robots even though their parents have a negative view of them.

  • In this study, the effects of yacon (Smallanthus sonchifolius) leaf on the quality characteristics of cookies were examined. In order to investigate its effects, four different amounts (0%: Control, Y-0.5, Y-1.0, Y-1.5) of yacon leaf powder were added to the cookie dough. Among the physicochemical and sensory characteristics, the density and pH of the dough, spread factor, color value, firmness, consumer acceptability, and Pearson's correlation coefficients were measured. Although there was no significant difference in pH of the doughs among the groups, density significantly decreased with increasing amount of yacon leaf powder (p<0.05). While the L, a, b values, and hardness decreased significantly, DPPH free radical scavenging activity increased significantly as the content of yacon leaf powder increased (p<0.05). Overall acceptability, appearance, taste, and texture between the control and Y-0.5 groups showed no significant differences. This study suggests the possibility of yacon leaf as an ingredient that increases the functionality of cookies.

  • This study was conducted to investigate the sensory and physicochemical properties of beef consomme made with different boiling times (1, 2, 3 and 4hrs). The sensory properties were evaluated with respect to both the acceptability (color, smell, mouth feel, taste, overall acceptability) and intensity characteristics (color, smell, clarify, taste). From the results, the 3hr treatment was most favored for color, smell, mouth feel, taste and overall acceptability, from the sensory evaluation tests. According to a quantitative descriptive analysis of the sensory evaluation for the product, the color, smell and taste gave higher scores with increases in the boiling time. 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 identified; the alanine, glutamic acid, arginine and leucine contents were high in the free amino acids of the consomme made with different boiling times. There were 3 free sugars identified, glucose, fructose and sucrose. The free sugar contents increased with increasing boiling time. There were changes in the mineral contents of the consomme made with different boiling time; with high K, Na and P contents. The mineral contents increased with increasing, boiling time. The results showed the consomme made by boiling for 3hrs was superior in both its sensory and physicochemical qualities.

  • The principal objective of this study was to assess the effects of various concentrations of added mulberry fruit powder on the quality characteristics of Jeolpyon. The chemical composition as a whole was 10.23% moisture, 8.03% crude protein, 5.40% crude fat, 2.51% crude ash, and 6.98% crude fiber. The mulberry fruit powder was added to rice powder at ratios of 2, 4, 6 and 8%. The moisture contents of the mulberry fruit Jeolpyon samples ranged between $50.75{\sim}52.66%$. With regard to the color values the L-value decreased and the a-value and b-value increased with increasing amounts of added mulberry fruit powder. In the mechanical evaluation of the mulberry fruit Jeolpyon, the hardness, adhesiveness, cohesiveness, springiness and chewiness values were lower in the Jeolpyon samples with added mulberry fruit powder than in the samples with more than 0% mulberry fruit powder, respectively. In the sensory evaluation, the overall acceptability was deemed highest at a 4% level of added mulberry fruit powder. In conclusion, the Jeolpyon prepared with 4% mulberry fruit powder added to rice flour was assessed to as optimal formulation, in terms of its overall acceptability and textural qualities.

  • This study was performed to the investigate the Yackwa quality according to the addition level of cellulose(0, 1, 3, 5 and 7% w/w flour). The color(L, a and b value), hardness, crude lipid content and sensory evaluation of Yackwa were measured. The values for color(L, a and b value) were not shown any significant difference among the all of Yackwa groups, but L(lightness) tended to be increased in 5 and 7% cellulose Yackwa groups than cellulose free Yackwa(control). The 7% cellulose Yackwa was harder than control, but the hardness of Yackwa didn't show difference in groups added below 5% cellulose compare to control. Crude fat contents showed no significant difference in the all Yackwa groups but tended to decrease in Yackwa groups added above 1% cellulose than control. It could be thought that fat absorption of Yackwa was affected due to adding a cellulose. There were not found any significant differences in the taste values for sensory evaluation according to cellulose level, and overall acceptability in below 5% cellulose Yackwa groups didn't differ from control. On the other hand the higher level of cellulose, the more crispness which was positively associated with overall acceptability. These findings could be thought that the addition of 3% cellulose(w/w) in preparing Yackwa were needed to reduce the fat absorption and to increase the crispness without changing the tastes and overall acceptability of Yackwa.

  • Aronia melanocarpa (black chokeberry) powder containing various bioactive compounds is widely used in the food industry. We examined the sensory attributes (taste, color, flavor, texture, and overall acceptability) of market milk, yogurt, and Kefir containing different concentrations of Aronia melanocarpa powder. In market milk, the scores of all categories except color were the same or lower in market milk containing 0.5%, 1.0%, 1.5%, or 2% Aronia melanocarpa powder than the control group (0%). No statistical difference in color and flavor was observed between Kefir and yogurt. However, there was a statistical difference between the control and treated groups in taste, texture and, overall acceptability (p<0.05). As the content of Aronia melanocarpa powder increased, color, flavor, taste, and overall acceptability scores generally decreased. Yogurt and Kefir, with the addition of 1% Aronia melanocarpa powder, displayed the highest scores.

  • The dried persimmon was effective in caring an inflammation, an ulcer and a burn and preventing hypertension and arteriosclerosis. At the Jejungsinpyun. dried persimmons gruel was beneficial to stomach and intestine and toned down voice. Based on Jejungsinpyuns and Sikryochanyo, dried persimmons gruel was developed for modern people. To standardize the dried persimmons gruel, physical properties and consumer acceptability was examined. The procedures of dried persimmons gruel was to make dried persimmons juice after soaking dried persimmons with same volume water during 24 hr and blending. To decrease the astringent taste of dried persimmons, dried persimmons juice and water with cinnamon (2%) was mixed and simmered during 3 min. Dried persimmons paste with cinnamon was added and the gruel was boiled more during 5 min. dried persimmons gruel was completed. The dried persimmons gruel were divided of 5 groups consisted of each 10, 15, 20, 25, 30 g dried persimmons. As dried persimmons content increased, lightness, apparent viscosity decreased. Acceptability test indicated the sample of dried persimmons : rice ratio at 2 : 5 had the highest overall acceptability and flavor. Considered to each, the sample of the dried persimmons : rice ratio at 2 : 5 met the purpose of the study.
