A study was undertaken to examine the effect of adding freeze dried maquiberry powder on the quality of pound cakes. Freeze dried maquiberry was added to the flour at a ratio of 0.5, 1, 1.5 and 2.5%. The antioxidant activity was estimated by DPPH free radical scavenging activity, the total phenolic compounds content, and flavonoid content in freeze dried maquiberry powder of pounds cakes. Antioxidative activity was highly correlated with the total phenolic and total flavonoids contents of freeze dried maquiberry powder of pound cakes (r=0.9126, p<0.001, r=0.8366, p<0.001, respectively). The quality characteristics of freeze dried maquiberry powder of poundcakes were estimated. The specific volume decreased significantly with increased substitution level of freeze dried maquiberry powder (p<0.01). The lightness significantly decreased with increased freeze-dried maquiberry powder of pound cake crust and crumb (p<0.01, p<0.01). The hardness and adhesiveness increased, while gumminess tended to reduce with increased maquiberry powder. The consumer acceptability score of 0.5~2.5% freeze dried maquiberry powder of pound cakes ranked significantly (p<0.01) higher than those of the other groups in overall preference. These results showed that freeze dried maquiberry powder is a good ingredient to increase consumer acceptability and health.

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.

In this study, to explore the use of lotus leaf powder, quality characteristics of sponge cake manufactured with different levels of lotus leaf power were investigated. We discovered that the pH, gravity, and cooling temperature of sponge cake increased as the content of lotus leaf power additive increased compared with those of the control group. Likewise, L and b levels of sponge cake increased with increasing level of lotus leaf power; 20% lotus leaf powder appeared to show the highest L and B levels, but levels were lower than those of the control group. Sponge cake levels of hardness, springiness, and cohesiveness increased as the amount of lotus leaf powder additive increased. In sensory evaluation, overall acceptability of 5% lotus leaf powder was the highest. Thus, it is possible to develop sponge cake with improved health-oriented aspects by addition of 5% lotus leaf powder.

This study was performed to determine the feasibility of developing a healthy yogurt using tofu whey concentrates separated by nanofiltration (NF). The curd yogurt was prepared from whole milk with added skim milk powder, in which the NF powder was substituted at 0, 6.25, 12.5, or 25% for the skim milk powder. The quality characteristics were evaluated for pH, titratable acidity, viscosity, color, and viable cell counts. There were no significant differences in pH or titratable acidity between the control (yogurt with added skim milk powder only) and the yogurts with added NF powder, after 24 hr of fermentation at $37^{\circ}C$. The apparent viscosities of the yogurts with added NF powder were higher ($3,197{\sim}3,574\;cps$) than that of the control yogurt (3,196 cps). Lightness decreased, while yellowness increased, as the amount of NF powder increased. Sensory evaluations showed that the NF powder could be substituted for the skim milk powder at 6.25% without lowering the yogurt quality.

The quality characteristics and antioxidant activities of Cheongpomook prepared with different amounts of aronia (Aronia melanocarpa) powder were studied. Freeze-dried aronia powder was incorporated into mung bean starch at different levels (1, 3 and 5% aronia powder based on the total weight of mung bean starch). Moisture content in control group was 89.7% and was not significantly different from the different levels of aronia powder groups. Syneresis, hardness, chewiness and gumminess were increased with higher amounts of aronia powder in Cheongpomook. In chromaticity determination, the L value of the samples decreased but the a and b values increased with increasing the levels of aronia powder in Cheongpomook. The total polyphenols, flavonoids and anthocyanin contents were proportionally increased with increasing the levels of aronia powder added in Cheongpomook. The antioxidant activity measured by DPPH and ABTS radical scavenging activities was significantly higher than control and increased proportionally to the aronia powder concentration. The sensory evaluation indicated that the 5% aronia powder showed the best preference in color, taste, flavor, hardness, and overall acceptance. These results suggest that aronia powder may be useful ingredient in Cheongpomook to improve quality and antioxidant potential.

In this study, Astragalus membranaceus powder was added (3, 6, 9%) during yeast bread preparation and its effect on product quality was examined. The results showed that the dough pH increased as the Astragalus membranaceus powder content increased. However, dough volume during fermentation did not differ significantly among the samples. Bread volume decreased (p<0.001) with an increasing amount of Astragalus membranaceus powder. Also, as the Astragalus membranaceus powder content increased, the Hunter’s color ‘L’ value of the crust decreased and the ‘a’ value increased, and for the crumb, the ‘L’ value decreased and the ‘a’ value increased. Textural property analysis indicated that hardness increased with an increasing amount of Astragalus membranaceus powder. However, up to the 6% level, there were no sensory attribute differences among the samples.
