This study presents the quality characteristics of blueberry bread. Blueberry fruit powder was added to bread dough at various concentrations ranging from 3~9%, after which physicochemical properties of dough and bread containing blueberry fruit powder were determined. The pH, loaf volume, specific loaf volume, dough volume and baking loss decreased with increasing amount of blueberry fruit powder in bread, whereas loaf weight and hardness were reduced. In particular, hardness appeared to be 1.98 times higher in the control without blueberry powder compared to the bread containing 9% blueberry powder. For color, increasing the amount of blueberry fruit powder reduced L and b values, whereas a value was increased. In the sensory evaluation, the highest overall preference score was observed in bread containing 6% blueberry powder, whereas the lowest score was observed in bread with 9% blueberry powder. From these results, blueberry bread with good acceptability has an optimum blueberry powder concentration of 6%.

This study was conducted to investigate the effective ratio of Sulgidduk to steaming chesnut powder. I measured the sensory and mechanical characteristics, moisture content and color values of Sulgidduk added by different amount 4 of types of steaming chestnut powder; 0% (Control-0 group), 1% (CP-1 group), 2% (CP-2 group), 3% (CP-3 group), 4% (CP-4 group). Moisture content of Sulgidduk with steaming chestnut powder ranged from 38.53% to 46.05%. The L-value and b-value of the color decreased with an increase in steaming chestnut powder; however, a-value of the color decreased with an increase in steaming chestnut powder. As a result of analysis the texture of Sulgidduk steaming chestnut powder, it's hardness, springiness was increased. According to the sensory evaluation, CP3 had the highest values in texture and overall acceptability. Based on the result, it's considered that the most desirable ratio is steaming chestnut powder CP3. The results of the study supported the benefits of steaming chestnut powder supplementation in Sulgidduk in the aspects of taste and functionality. The degree of further increase in Sulgidduk with steaming chestnut powder without causing an adverse quality effect, remain for future study.

This study was investigated cranberry powder substituted for flour in pound cake recipes with the amounts of 0, 4, 7, 10, and 13%. Cranberry powder have of 6.47% of moisture content, 3.38% of crude protein, 4.92% of crude fat and 0.43% of crude ash. No significant difference in weight was found from increased cranberry powder concentration. Volume and specific loaf volume have decreased as the cranberry powder content increased. No significant difference in moisture and brix was found from increased cranberry powder concentration. pH have decreased as the cranberry powder content increased. 'L' and 'b' decreased with an increase in the cranberry powder concentration, but 'a' increased. The texture measurement result showed that the hardness and chewiness of cake have decreased as the cranberry powder content increased. springiness, cohesiveness and adhesiveness showed no significant difference with the increasing amount of caked cranberry. Overall preference scores showed a high overall acceptability for the cake made with 7% cranberry powder.

This study was carried out to investigate the acceptable ratio of Sulgidduk with added soybean curd residue powder. The moisture content of Sulgidduk with added soybean curd residue powder (0${\sim}$ 10%) ranged from 40.54 ${\sim}$41.38%, and there were no significant differences between the addition of soybean curd residue powder and control. There were also no significant differences in swelling power and pore ratio from control to the addition of 4% soybean curd residue powder. However, these decreased with increasing addition of soybean curd residue powder of more than 6%. The L (lightness) value decreased with increasing addition of soybean curd residue powder, but the a (redness) and b (yellowness) values increased significantly. As the amount of soybean curd residue powder increased, the hardness, cohesiveness, springiness and gumminess decreased, and, the decrease was especially significant with addition of more than 6%. With increases in the storage period, the hardness, springiness and gumminess increased, while cohesiveness decreased for all additions of soybean curd residue powder. In sensory evaluations, Sulgidduk with the addition of 4% soybean curd residue powder was the most preferred with regard to overall quality. These results indicated that the Sulgidduk with 2% and 4% added soybean curd residue powder exhibited the best quality.

The purpose of this study was to investigate the effects of the addition of various concentrations of antler powder on the physicochemical and sensory characteristics of mango jelly As for pH and viscosity of the mango jelly, antler powder added group showed higher pH and viscosity than that of control group. As for turbidity, absorbance increased significantly(p<.001) by the addition of antler while permeability decreased. The syneresis increased with the passage of time. According to sensory evaluation, Sleekness showed the highest by adding $0.2\%$ antler powder in mango jelly. The hunter color L and b value decreased significantly(p<.001) by adding antler powder. The mechanical properties such as hardness, springiness, cohesiveness and brittleness were highest by adding $1.0\%$ antler powder while gumminess was highest by adding $0.2\%$ antler powder in mango jelly. Overall quality, taste, appearance, texture were most superior by adding $0.2\%$ antler powder in mango jelly. From these test results, the optimum recipe for mango jelly added with antler powder was $0.2\%$ of antler powder, $10\%$ sugar, $\2%$ agar and 351.2ml of mango juice.

The quality characteristics and antioxidant activity of Tteokbokkidduk alone or supplemented with 3%, 6%, 9%, and 12% wheat bran powder were assessed, to increase use of the wheat bran by-product of wheat milling. The moisture content, pH, and starch elution of Tteokbokkidduk increased with increasing wheat bran powder, while the water absorption rate did not. The L color value decreased and the a and b values increased with increasing wheat bran powder. Scanning electron microscopy of Tteokbokkidduk prepared with 0% and 3% wheat bran powder revealed uniform pore size distribution. In terms of texture profile analysis, hardness and chewiness increased, while cohesiveness decreased with increased content of wheat bran powder. Acceptance was highest for samples with 6% wheat bran powder. Quantitative description analysis (QDA) revealed increased brownness, roughness, nutty, bitterness, astringency, savory character, and hardness, and decreased adhesiveness, springiness, and chewiness with increased wheat bran powder. Principal component analysis (PCA) revealed highest overall acceptance of samples prepared with 6% wheat bran powder, reflecting the relatively low values of detrimental sensory characteristics. Antioxidant activities of Tteokbokkidduk increased as wheat bran powder content increased. The addition of 6% wheat bran powder resulted in excellent Tteokbokki in terms of acceptance, quality, and antioxidant activity.
