This study was conducted to investigate the effects of paprika juice on the quality characteristics of Jeung-Pyun (fermented and steamed rice cake). Jeung-Pyun was prepared with four different levels of orange paprika juice (0%, 10%, 25% and 50% replacement of water). The proximate composition analysis showed that moisture contents of Jeung-Pyun were 48.72∼49.36%, and crude protein, lipid and ash contents were 2.94∼3.13%,0.46∼0.63% and 0.60∼0.65%, respectively. The pH of Jeung-Pyun batters was decreased from 4.74∼4.83 to 4.27∼4.38 during 4 hours of fermentation at 35$^{\circ}C$. The maximum expanded volume was observed in control group, followed by 10% group, 25% group and 50% group and the volume expansion was decreased with the increased amount of paprika juice. The "L" value (lightness) was the highest in control group and decreased with paprika juice addition, while the "b" value (yellowness) was increased as the amount of paprika juice was increased. Rheology test showed that there were no significant differences in hardness an cohesiveness among four groups. Springiness and gumminess were the lowest in control group and increased with the increased amount of paprika juice. Results of sensory evaluation showed that there were no significant differences in scores of cell uniformity, sweetness, moistness and overall desirability between control and 10% group. Therefore. Jeung-Pyun prepared with 10% paprika juice was evaluated as the most acceptable one among test groups when compared to control.
In this study, kiwi fruit, which has various medical actions and excellent functionality, was used together with gruels for comparison and analysis of to compare and analyze the changes in physico-chemical quality of a kiwi fruit-gruel according to the amount of kiwi concentrate added to the gruel. Analysis on the sensual quality of kiwi fruit-gruel spread was done to indicate to it was executed to find out the merchandising potential of the preparation and to provide basic data for gruel commercialization. Increasing content of kiwi concentrate decreased the solid content and pH of kiwi fruit, and increased sweetness and viscosity. Significant changes in chromaticity to L(lightness) and a(redness), texture qualities of hardness and cohesiveness, gumminess, springiness, color, flavor, sourness, and sweetness were evident with increasing kiwi concentrate. Concerning overall acceptability and sensory evaluation, 20% softness samples were most preferred. The findings may lead to enhanced medical/nutritional activity and functionality of kiwi fruit-supplemented gruel. The more the kiwi concentrate was added to the gruel, solid content and pH of the kiwi fruit-grue decreased. The sweetness and viscosity of kiwi fruit-gruel increased. For chromaticity to L(lightness) and a(redness) of the gruel decreased and showed significant difference between sample groups. For texture, there were significant changes shown for hardness and cohesiveness the amount of kiwi concentrate added was different, increased There was a significant change between samples for gumminess. As for springiness, there was a significant change between samples. There were significant difference between each sample for color, flavor, sourness, sweetness. For softness, overall-acceptability and sensory evalution 20% group was most preferred based on this study, from the physico-chemical and sensual perspective, 20% group is highly recommended for adding kiwi concentrate into gruel. In conclusion, this study is meaningful as it enhanced the functionality and quality of a gruel by combining kiwi fruit with various medical action and excellent functionality, with Kiwi Fruit and presented a basic material for creating a kiwi concentrate combined gruels.
This study was conducted to preserve the quality of Gangjung (Traditional Korean cookies) during storage with the addition of sorbitol in Gangjung dough. Sorbitol was added with different levels (0, 1.5, 3%) in the Gangjung dough and the Gangjung samples were stored for different periods (1, 16, and 31 days). Compared to the control group, the Gangjung samples with sorbitol groups had higher moisture content, expansion ratio, and ceil size. As the storage was extended, peroxide values, hardness, fracturability, chewiness and stickiness to teeth were increased, while cohesiveness, moistness, and degree of melting were decreased. From the PCA in the sensory analysis, Gangjung with addition of 3% sorbitol stored for 1, 16, and 31 days showed high levels in moistness, cohesiveness, degree of expansion, cell size, and degree of melting, whiie Gangjung in control group stored for 16 and 31 days showed high levels in fracturability, heated oil flavor, chewiness, and stickiness to teeth. The moisture content of Gangjung was significantly increased as the level of sorbitol was increased. The changes of physicochemical and sensory characteristics by storage were increased in control groups the most, 1.5% sorbitol groups the next, and 3% sorbitol groups the least. Therefore, the sorbitol added groups could be delayed in the quality deterioration during storage, especially in the texture, and could be increased in the preservation of Gangjung.

Objectives : This study was intended to compare coping style, family support, and parenting behavior between adolescent groups with different levels of perceived stress. Methods : A total of 795 high school students participated in this study. First, they were tested on the Perceived Stress Scale and then were separated into two groups depending on the level of perceived stress. Both groups completed the Scale for the Coping Style, the Family Environment Scale (relationship subscale) and Parenting Behavior Inventory. Results : The high stress group had significantly higher scores on all their coping scores than the low stress group. Also, the high stress group had significantly higher family conflict scores, lower family cohesiveness scores and lower expression scores than the low stress group. The high stress group experienced negative parenting behavior from both parents more often than the low stress group. In the adolescents with low family cohesiveness and expression, the use of active behavioral coping was decreased, if the higher stressful events occurred. The use of avoidant coping by these adolescents increased when there were higher levels of stress in their environment. Conclusion : Low family support directly reduced the usage of active behavioral coping and increased the use of avoidant coping strategy through the mediation of high stress condition.
The following research was done to develop a low calorie muffin that has good taste, as well as nutritional benefit. This was done through adding various nutritional qualities of Makgeolli Lees to muffins. It was found that adding Makgeolli Lees substantially increased the amount of ash, crude protein, crude fiber, and moisture. However, it decreased the amount of crude fat. It was also found that the volume, height, and weight all increased with a lower baking loss rate. Other testing on the hardness, expand chewiness, gumminess, and cohesiveness of the muffins with different amounts of Makgeolli Lees found that more Makgeolli Lees led to a lower hardness and chewiness. However, it did not affect the gumminess. "MLM10" with 10 g of added Makgeolli Lees had a cohesiveness that was significantly different from other samples. The cohesiveness of the other samples was substantially lower. "L-value", or lightness, as well as yellowness, decreased as more Makgeolli Lees was added. On the other hand, "a-value", or redness, increased as more Makgeolli Lees was added. A sensory test proved that Makgeolli Lees added muffins were not preferred over the control group in its color, texture, and overall preference, but was evaluated as "good". However, the Makgeolli Lees added muffins were evaluated better than the control group in the categories of "expanded", "uniformity", and "he size of the pores". Therefore, creating muffins by using Makgeolli Lees instead of fat was proven to be possible, and furthermore proved to be a viable substitute.
This study added black lentil ethanol extract to Yakgwa at ratios of 0%, 0.5%, 1.0%, and 2.0%, and its quality characteristics were compared to those of the synthetic antioxidant BHT added to Yakgwa. Yakgwa with black lentil extract had lower moisture content than Yakgwa with BHT (3.98%) but higher content than the control group (5.72%). Higher black lentil extract resulted in less moisture content (p<0.001) as well as a faster expansion rate and oil absorption rate (p<0.001). Scanning Electron Microscopy (SEM) showed that as black lentil extract content increased, pores merged and collapsed, whereas the number of pores decreased and pore size became larger. For chromaticity, all L, a, and b values of the group containing black lentil extract were higher compared to the control group and group with BHT (p<0.001). For texture, as amount of added black lentil extract increased, hardness (p<0.001) and gumminess (p<0.01) increased while cohesiveness (p<0.01) decreased compared to the control group. For sensory characteristics, Yakgwa with 1.0% black lentil extract showed the best preference for all items except for off-flavor. Thus, 1.0% black lentil added to Yakgwa was the best in terms of functionality including preference.
The aim of this study was to investigate the effects of adding different amounts (0, 4, 8, 12, 16%) of green laver powder to Sulgidduk, a traditional Korean rice cake product, in terms of textural properties and sensory characteristics. During storage, moisture content was reduced less in the green laver-added samples as compared to the control group. With increasing additions of green laver powder, L-values decreased, a-values increased significantly, and b-values decreased; however, no changes were observed in the control group. In the mechanical evaluations, hardness increased less during storage in the green laver added samples than in the control group. Adhesiveness did not differ significantly by the addition of green laver powder. Springiness, cohesiveness, gumminess, and chewiness showed significant differences, and increased or decreased repeatedly during storage. In the sensory evaluations, the 16% green laver group received the highest scores for color, flavor, and taste Moistness and softness were evaluated higher in the green laver groups as compared to the control group; however, moistness, softness, and elasticity did not differ significantly during storage.
This study was performed to find out the quality characteristics of Noodles by addition of red ginseng powder(0, 2, 4, 6, 8%). The quality characteristics of the sample were estimated in terms of general com-position, color difference, cookery characteristics(water absorption, volume of cooked noodles, turbidity), texture profile analysis and sensory evaluation. The protein, lipid, ash, Na and water binding capacity did not show significant difference in any of the groups. In red ginseng powder added groups, moisture contents, a and b values significantly increased but L value considerably decreased(p<0.05). The weight, volume, water absorption of the cooked noodles and turbidity of 8% of red ginseng powder added group were significantly higher than the control group(p<0.05). In texture profile analysis, adhesiveness, gumminess, hardness and springiness significantly decreased(p<0.05) with more red ginseng powder added. Chewiness and cohesiveness significantly(p<0.05) increased with the 4, 6, 8% of red ginseng powder added. In sensory evaluation, surface color was very good in the 8% red ginseng powder added group while taste and flavor of red ginseng were very good except the 8% red ginseng powder added group(p<0.05). Appearance and overall quality were highest in the 4% red ginseng powder added group(p<0.05). Therefore, noodles containing 4% red ginseng powder were most preferable.
