  • This study aims to investigate the quality characteristics of breads with the addition of sweet pumpkin powder. Farinogram showed that the absorption rate of the dough decreased, the development time and stability became shortened, and the degree of attenuation tended to be grown along with increasing the amount of pumpkin powder. From the amylogram, it was found that the gelatinization starting temperature and the maximum viscosity of pumpkin powder added dough seemed to be decreased as the amount of pumpkin powder was increased. Extensogram showed that there was a decrease in the degree of extension of the dough added with increasing the amount of pumpkin powder, while an increase in the degree of resistance and resistance/extensibility. The lightness (L value) and redness (a value) of bread was found to be decreased with increasing the amount of pumpkin powder, while the yellowness (b value) increased. In terms of the dough texture, for which the hardness, cohesiveness and gumminess of the dough were measured, there were no significant differences between groups, while the dough added with 8.0% pumpkin powder showed a significant decrease in the elasticity. The results of sensory evaluation showed that the highest score of color (p<0.05) and taste (p<0.05) were obtained from the bread added with 6.0% and 8.0% pumpkin powder, while the highest score of texture in control and 3.0% pumpkin bread. In addition, the highest score of flavor (p<0.05) and overall acceptance (p<0.05) were observed in bread added with 6.0% pumpkin powder. Upon the results of this study, it was assumed that the development of food products using pumpkin are prospective in response to health-oriented consumers.

  • This study determined the effects of soybean oil$2\%$) and chitosan($1\%$) on the quality characteristics of Omija Jelly made of various starches (mungbean starch, cowpea starch and corn starch). RVA(Rapid Visco Analyzer) viscosity was measured for starches suspended in Omija aextract with $2\%$ soybean oil and $1\%$ chitosan. The color value, syneresis, texture(rupture test and TPA test) and sensory properties of the samples were measured. Gelatinization of cowpea starch was expedited by adding soybean oil and chitosan. Otherwise, gelatinization of mungbean starch and com starch was retarded by adding chitosan. The lightness(L) and the syneresis of Omija Jelly with soybean oil and chitosan were decreased, indicating the increased transparency and stability of Omija Jelly. Rupture stress and rupture energy of Omija Jelly were decreased by adding soybean oil. Rupture stress was increased and rupture energy was decreased by adding chitosan. The addition of soybean oil improved texture of Omija Jelly, indicating that the springiness, cohesiveness and chewiness of Omija Jelly were increased and adhesiveness was decreased. By adding chitosan, the springiness and hardness of Omija Jelly were increased and the cohesiveness and adhesiveness were decreased. The overall acceptability of Omija Jelly made of $6%$ or $7\%$ cowpea starch and com starch was increased by adding soybean oil and chitosan, but the quality characteristics of Omija Jelly made of mungbean starch were not influenced by additives such as soybean oil and chitosan.

  • This research was designed to compare the subjective evaluation of texture image and preference by structure and sensible characteristics of women's suits fabrics between on- and off-line. 78 subjects who majored in fashion design evaluated the sensibility image and preference of 15 various kinds of specimens on- and off-line. Factor analysis, t-test, Pearson correlation and regression were used for a statistical analysis by SPSS WIN 13.0. The results of this study were as follows: 1. Women's suits fabrics were classified according to five sensibility image factors: 'classic', 'sophisticated', 'natural', 'characteristic', and 'practical'. 2. The results of the t-test showed that there were no differences between the on- and off-line evaluation of sensibility images. 3. The analysis of correlation indicated that the 'classic'-'sophisticated' and 'natural'- 'practical' sensibility images show a significant correlation between the two kinds of evaluation. 4. The results of regression revealed that 'sophisticated', 'characteristic' and 'practical' sensibility images had an effect on the purchase preference of women's suits fabrics. 5. 'Sophisticated', 'characteristic' and 'classic' sensibility images had an effect on the tactile preference of women's suits fabrics. 6. The structural characteristics of fabrics: thickness, weave and weight had an effect on the 'classic' sensibility image. Thickness had an effect on the 'sophisticated' sensibility image and fabric count had an effect on the 'characteristic' sensibility image.

  • The principal objective of this study was to evaluate the quality characteristics of mungbeanmook prepared with five different levels (0, 5, 10, 15, and 20%) of Gugija (Lycii fructus) infusion. We analyzed Hunter's color values, pH, texture characteristics, and perfomed sensory evaluation of mungbeanmook prepared with Gugija infusion. The pH levels of mungbeanmook ranged between 5.45 and 6.12 and did not show significant differences. As Gugija infusion concentration increased, the color lightness "L" value decreased, whereas redness color "a" value and yellowness color "b" values increased (P<0.05). With regard to mechanical texture properties of the mungbeanmook samples, as the Gugija infusion concentration increased, the scores of hardness, chewiness, and gumminess all significantly decreased (P<0.05) whereas there were no significant differences in springiness or cohesiveness. The results of the sensory evaluation showed that the score of the LFLT10 sample (10% Gugija infusion) was significantly higher than those of others in terms of taste, color, flavor, texture, and overall quality (P<0.05). Taken together, the recommended optimum level of Gugija infusion in mungbeanmook is 10% for sensory evaluation. Gugija infusion can be a useful approach to improving quality of mungbeenmook as a functional food.

  • The purpose of this study is to investigate the effect of mulberry juice on the quality characteristics of mulberry jelly. Samples of mulberry jelly were divided into four groups by adding different mulberry juice. The four groups were divided into MJ-0 (mulberry jelly without mulberry juice), MJ-30 (mulberry jelly with 30% mulberry juice), MJ-50 (mulberry jelly with 50% mulberry juice) and MJ-70 sample (mulberry jelly with 70% mulberry juice). The moisture content in all MJ samples decreased with an increase in the addition of mulberry juice. The highest crude ash content, brix and pH in MJ-70 sample were 0.66%, 25.00 °Brix and 4.84, respectively. No significant crude fiber changes were observed in all MJ samples. In the case of Hunter's value, 'L' values in all MJ samples decreased with an increase in the addition of mulberry juice. Turbidity, brown degree, total phenolic content, DPPH radical scavenging activity and content increased with an increase in mulberry juice. Levels of Ca, K, Na, and Mg contents in all samples were higher than those of the other minerals. Texture in all MJ samples on the whole decreased with an increase in mulberry juice added. However, no significant texture charges were observed in all samples. The highest scores for the overall acceptance (4.52) were found in the MJ sample with 50% mulberry juice.
