  • Traditionally, the persimmon Gojongsi (Diospyros kaki Thunb) is peeled to make dried persimmons and the skins are thrown away. In this study, the quality characteristics of cookies containing persimmon peel powder were tested for recycling of the persimmon peels. The amounts of persimmon peel powder added to the cookies were about 0, 5, 7, 9 and 11%. The densities of the cookies of the control group and the persimmon peel powder containing experimental group were 1.25 and 1.25~1.37 respectively. The pH was 6.02 for the control group and 5.95~6.01 for the experimental group. Significant differences in the moisture content were observed between groups at 3.34 and 2.16~3.31 for the control and experimental groups, respectively (p<0.05). The spreadabilities and loss rates of the cookies increased with increasing amounts of persimmon peel powder (p<0.05). In contrast, the loss rates and leavening rate of the cookies decreased significantly with decreasing amounts of persimmon peel powder (p<0.05). The lightness of the cookies showed significant decrease (p<0.05), while the redness and yellowness increased with increasing amounts of persimmon peel powder. The hardness (kg) of the control group was 0.847 while that of the experimental group was 0.904~1.110. In the QDA, the results of sensory characteristic analysis showed that the experimental group earned 11% higher scores for color, flavor, taste, and bitterness, 7% higher for appearance and 9% higher for after taste. The consumer acceptance test revealed the experimental group to have a 7% more positive evaluation for color, favor, taste and texture than the control group. On the grounds of the experiment above, the optimal mixture ratio from the sensory test was found to be 7% persimmon peel powder in the cookies.

  • This study is based on the utilization of pine mushroom for processing products by development of pine mushroom Jung-Gwa. The results were summarized as follows: Pine mushroom Jung-Gwa were prepared with four different amounts (20, 30, 40, 50%) of honey. Pine mushroom Jung-Gwa color value was the highest by 20% soaking honey-water product and 40% soaking honey-water product was the lowest. Strength and hardness of 20% soaking honey-water product was the highest. Appearance to product of 50% soaking honey-water was the highest preference by all age of except 20's. The honey content of more and more external appearance preference was became higher. Product of 40% soaking honey-water was best by flavor of pine mushroom Jung-Gwa. A sugary tastes comparison 50% soaking honey water to 40% soaking honey water was not distinction. The texture was appeared a statistically significant difference by products of 20%, 30% soaking honey-water. Product of 20% soaking honey-water was favorite in 20's and product of 30% soaking honey-water was favorite in 30's. In overall preference test for pine mushroom Jung-Gwa of 40% soaking honey water was preferred by all age. Oligosaccharide helped geriatric diseases and cheaper. Thus this study used oligosaccharide but the result was not a statistically significant difference of pine mushroom Jung-Gwa products quality by comparison honey-water to oligosaccharide. Therefore oligosaccharide utilization products was thought worth a lot more by processing price and functional.

  • This study was conducted to evaluate sensory properties of sugar cookie containing sucralose. Relative sweetness of sucralose to sucrose in a cookie system was examined with paired comparison tests and the result was applied to low calorie cookie preparation using polydextrose as a bulking agent. Physical and sensory properties and consumer acceptability of sugar cookies containing various levels of sucralose and polydextrose were evaluated. Relative sweetness of sucralose to sucrose was 700 times in sugar cookie. Instrumental hardness and fracturability increased as the levels of replacement with sucralose increased. Spread ratios of sugar cookies where sucrose was partially and totally replaced with sucralose and corresponding amount of polydextrose were higher than that with sucrose only. Intensities of bitter taste, salty taste, hardness and molar packing of sugar cookies where sucrose was entirely replaced with sucralose and polydextrose were higher than that those of the other cookies. Acceptability test indicated 75% replacement with sucralose and adequate amount of polydextrose can be used without harming overall, appearance and flavor acceptability while texture acceptability was slightly lower.

  • As interest in health has recently increased, many researchers have investigated the utilization of functional foods by confectioneries and bakeries. However, research on loaf bread containing beets has not been conducted. To investigate the optimal ratio of beet in loaf bread containing beet powder, characteristics of loaf bread according to 2%(B2), 4%(B4), and 6%(B6) beet powder per wheat flour were examined. The experimental results were as follows. Fermentation rate was reduced as content of beet powder increased compared with the control, whereas pH levels of dough and loaf bread significantly increased as content of beet powder increased. As content of beet powder increased, volume of loaf bread decreased, whereas specific volume increased. There was no significant difference in volume of loaf bread between the samples. As far as color changes are concerned, as content of beet powder increased, L value decreased, whereas a and b values increased with significant differences between the samples. Characteristics were examined by sensory evaluation of loaf bread containing beet powder. Color of inner texture and peel color of loaf bread significantly increased as content of beet powder increased. Size of air pores was largest in B4, and there was no significant difference in the uniformity of loaf bread between the control and experiment groups. As content of beet powder increased, rigidity of bread was reduced. Control showed the highest elasticity, whereas moisture level was highest in B2 with no significant differences between the samples. The flavor of beet was stronger as content of beet powder increased. In the preference test, B4 showed the highest preference scores for texture, flavor, taste, and overall likeness but not appearance. The experimental results showed that B4 among all control and experimental groups had the most suitable baking characteristics and an optimum content of beet powder. Therefore, B4 can be considered as the most appropriate for making loaf bread containing 4% beet powder in terms of physical and sensory characteristics. This is a new product that satisfies overall sensory preferences and has improved functionality.

  • As an exaggerated-shoulder becomes a growing trend women's clothing, the crescent shaped sleeve with parallel style lines in the arm hole is a highly used women's sleeve pattern. This study develops and provides an applicable method for making the crescent shaped power shoulder sleeve. An efficient basic method for making the 2 piece crescent shaped sleeve was developed and the sensory appearance test was carried out with experimental clothes. There are two principles for making the crescent shaped sleeve: having a style line in the sleeve and pasting part of the cut arm hole of the bodice to the sleeve. The latter would be more convenient for a 2 piece sleeve, mostly used for jackets. The crescent shaped sleeve used in power shoulder jackets should set the shoulder angle as you wish to extend and raise the shoulder point of the bodice and sleeve to the same height. For a stronger power shoulder image, a 3 piece sleeve has a better appearance. Also, the height of the shoulder has to be enhanced with a shoulder pad for a more stable sleeve.

  • This study produced instant Gochujang(red pepper paste) with enhanced convenience by increasing nutritional value and palatability, and by reducing production period, adding in the red pepper seed in the red pepper paste production in order to increase the use of the red pepper seed that is not used often as a food ingredient even though its nutrition value when producing red pepper paste was proven. Moisture content, pH, L-value, a-value, b-value, sugar contents, and salinity of instant Gochujang tended to increase as the amount of red pepper seed increased, while viscosity manifested the opposite trend. Sensory evaluations were conducted on instant Gochujang to assess differences in characteristics, which demonstrated that as the amount of red pepper seeds powder increased, the intensity of redness for the red pepper paste's external appearance, luster, spicy flavor and taste, and savory taste were evaluated strong. Meanwhile, fermentation value, which is red pepper paste's foremost weakness was evaluated as weak. Moreover, there was no difference in the size of the grain when compared to the contrast group consisting of regular red pepper paste. The results of preference test demonstrated that the RG3 with 30% of red pepper seed is optimal in terms of the external appearance, taste, texture and overall preference.
