  • Purpose: This study investigated the quality characteristics of vegetable pancake prepared with various levels of barley flour. Methods: The pH level and spreadability of the batters as well as the color, texture, and sensory evaluation of the vegetable pancake were analyzed. Results: The results show that spreadability of batter significantly decreased as the substitution amount of barley flour increased (p<0.001). The pH level of the batter significantly decreased as the substitution amount of barley flour increased (p<0.001). Redness and yellowness increased as the substitution amount of barley flour increased. For texture, the sample groups with substituted barley flour showed high characteristics of hardness, gumminess, and chewiness. Principal component analysis showed that the sample group with a high substitution amount of barley flour was characterized by relatively high darkness, roasted grain aroma, bitterness, astringent, and chalkiness. Acceptance test found that the sample group with 15% barley flour received higher acceptance than the sample group with 0% barley flour in terms of color, texture, and overall acceptance. Conclusion: Acceptance test found that the sample group with 15% or 30% of barley flour had significantly higher or similar acceptance attributes than the sample group without barley flour, which suggests the possibility of developing vegetable pancake with barley flour.

  • This study investigated the physicochemical and sensory characteristics of Jeungpyun prepared with various levels of barley flour and Hizikia fusiformis powder. The pH, volume, and spreadability of the dough as well as the moisture content, color, texture, and sensory evaluation of Jeungpyun were analyzed. The results show that the pH of dough decreased in all sample groups with fermentation time and ultimately revealed a pH level ranging from 5.36~5.44. The spreadability of the dough significantly decreased as the substitute amount of barley flour increased; the sample group with 1% Hizikia fusiformis powder showed a significantly larger spreadability than the sample group with 2% Hizikia fusiformis powder (p<0.01). The moisture content of Jeungpyun significantly increased as the substitute amount of barley flour increased (p<0.01). Lightness and yellowness were reduced as the substitute amount of Hizikia fusiformis powder increased. In measuring texture, the 50% sample group with a high substitute rate of barley flour was observed to have high characteristics of hardness, gumminess, and chewiness. The results of the acceptance test show that the sample group with substituted 50% barley flour and added 2% Hizikia fusiformis powder had a higher acceptance than the sample group with 0% barley flour in terms of color, flavor, texture, and overall acceptance.

  • 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.

  • This study was conducted to investigate the quality characteristics of the bread with red ginseng powder(RG). Four different powder concentration levels of 0, 3, 6, and $9\%$ were added to flour to make the bread. The appearance, pH, water holding capacity, specific volume, color, texture, and sensory properties were analyzed. pH of bread with RG had no difference according to the content of the red ginseng powder. The specific volume of the bread containing $0,\;3,\;6\%$ were bigger than that of the bread with $RG-9\%$. The water holding capacity of the bread with $RG-9\%$ was the highest. As the amounts of RG increased, L-values of the bread crumb were decreased and a- and b-values were increased. As a result of texture measuring by texture analyzer, hardness and gumminess were not affected by the addition of RG. Also, springiness, cohesiveness, and chewiness were not significantly different among the control, $RG-3\%\;and\;RG-9\%$. In sensory evaluation, color, flavor, taste and overall acceptability in the bread with $RG-9\%$ were significantly lower than the control and the other groups. On the other hand, the best result for sensory characteristics showed when red ginseng powder at $3\%$ level was added to the bread.

  • The principal objective of this study was to determine the appropriate water content for optimal texture in high omega-3 fatty acid saury nuggets. The approach adopted in this study essentially involved variations in water levels(0{\sim}25%$). The main ingredients of the nuggets included saury mince, mild pizza cheese and hydrated textured soy protein concentrate. The formulated products were molded(dia. 4.5, thickness 1.5 cm, 20 g), battered lightly, flash-fried far 4 min at $160^{\circ}C$ and frozen until they were tested. The frozen nuggets were cooked to $65^{\circ}C$, then subjected to sensory evaluation, texture analysis at 80% deformation, and expressible fluid tests. The moisture contents in the nugget batter and the cooked nuggets were determined. In our sensory evaluation, nugget texture was adjudged the best in the nuggets prepared with a 20% water level(S5). The hardness and chewiness in the nuggets were reduced with increases in the water level. However, when the nuggets contain more than 15% water(S4, S5, S6), we noted no significant differences in the hardness values. The difference in moisture content between the uncooked nugget bat or and the cooked nugget was most profound in the nugget prepared with a water level 25%(S6). The nugget prepared with a water level 25% was also the highest in expressible fluids, and was also highest in internal moisture content. The texture preference of nuggets was correlated positively with moistness(r=0.881) and moisture content(r=0.827), and correlated negatively with firmness(r=-0.870) and cohesiveness(r=-0.839), and these correlations were significant.

  • The purpose of this study was to clarify the effects of constituent characteristics and the mechanical properties by KES-FB system on the visual texture images and preference of men's suit fabrics. Twenty different kinds of black fabrics, which were used mainly for the spring and summer men's suits, were selected and the subjective evaluation of the visual texture images was tested. Sixty experts in department of clothing and apparel industries participated in the subjective evaluation. Factor analysis showed visual texture images were classified into 4 categories : 'bulkiness', $'extensibility{\cdot}rapability'$, 'flexibility' and 'smoothness'. All of relationships were established between the mechanical properties and the visual texture images except the relation between 'flexibility' and bending properties. The significant factors affecting preference were 'smoothness', compression energy(WC), fabric count and 'flexibility', As the fabrics had higher value for 'smoothness' and 'flexibility' , and lower ones for compression energy and fabric count, they tended to be more preferred.
