The purpose of this study was to examine the qualities of muffins with 0, 3, 6, 9, and 12% amaranth leaf powder. The specific gravity of muffins prepared by adding amaranth leaf powder was higher than that of the control group. The pH of batter and muffins were decreased with the addition of amaranth leaf powder. The height, weight, volume, and specific loaf volume of muffins were decreased, while the baking loss rate of muffins was increased by the addition of amaranth leaf powder. The moisture content of the samples with amaranth leaf powder was lower than that of the control group. DPPH radical scavenging activity of the control group was 16.23%, whereas the samples with amaranth leaf powder ranged from 23.06~33.63%. In crumb color, the L and a value were decreased, although b value was increased significantly by the addition of amaranth leaves powder. The hardness, springiness, cohesiveness, chewiness, and brittleness of the textural properties of muffins were significantly decreased by the addition of amaranth leaf powder. Sensory evaluation scores in terms of after swallowing, appearance, odor, taste, texture, and overall preference of groups with 3% and 6% of amaranth leaf powder did not show any significant difference when compared to the control group. Based on the above results, using less than 6% of the amaranth leaf powder appears proper to make muffins.

The study investigated the quality characteristics of white castella prepared with 0, 10, 20, and 30% burdock (Arctium lappa L.) powder. The specific gravity and weight of castella increased with higher burdock powder content. Height and baking loss rate of castella were not significantly different among the samples. The pH of castella decreased with increasing burdock powder content, whereas $^{\circ}Brix$ of castella increased. Hunter L and b values of crust increased, whereas a values decreased with addition of burdock powder. Hunter L values of crumb decreased, whereas a and b values of crumb increased. The hardness of castella increased upon addition of burdock powder, whereas fracturability, springiness, cohesiveness, gumminess, and resilience decreased. DPPH radical scavenging activity and total polyphenol contents increased significantly upon addition of burdock powder (P<0.05). In the sensory evaluation, crust color, crumb color, and flavor were highest in the control group. Moistness had the highest scores in castella containing 20 and 30% burdock powder. Chewiness and overall acceptability were higher in castella added with 10% burdock powder than in the control and other samples, but there were no significant differences among the samples.

Dough fermentation characteristics and quality characteristics of bread added with different concentration(0, 30, 40 and $50\%$ against water) of submerged-culture broth of Fomitopsis pinicola mycelium (CM) were investigated There were positive correlations between CM concentration and dough pH(r=0.98), acidity(r=-0.88), dough thickness(r=0.95) and dough strength(r=0.95). Baking loss rate was decreased with increasing of CM concentration. There was no significant difference between loaf volume index and CM concentration ($30\~40\%$, but the index of CM $50\%$ bread was lower than that of control. L* value of top crust in the CM $50\%$ bread was significantly lower than those of CM $0\~40\%$ bread, while the value of internal tissue was increased with increasing of CM concentration. In the CM $30\~40\%$ bread, hardness was lower, but there were no significant difference in cohesiveness, springiness, chewiness and brittleness compared with control. Appearance, color, taste, texture and overall acceptability of CM $30\~40\%$ bread were similar to those of control. In the results estimated by correlation analysis, the increased pH of the dough by adding CM allowed lowering hardness of the bread By adding CM in bread, retrogradations were delayed, and growth of mold was decreased during storage. In conclusion, the optimum concentration of CM in bread which showed anti-diabetic effect as well as not dropped quality characteristics were $30\~40\%$.

The purpose of this study was to evaluate the quality of castella added with different concentrations (0%, 5%, 10%, and 15%) of Panax ginseng sprout powder. The specific gravity of castella made with 15% ginseng sprout powder was the highest (0.65), and baking loss rate was highest well. However, the height and weight of castella were highest in the control. The pH of castella decreased with increasing levels of Panax ginseng sprout powder, whereas sugar content of castella did not show significant differences. The Hunter L, a, and b values of crust decreased as the concentration of Panax ginseng sprout powder increased. The Hunter L and a values of crumb decreased as the concentration of ginseng sprout powder increased, whereas b values of crumb increased. The gumminess and chewiness of castella increased by addition of Panax ginseng sprout powder, whereas cohesiveness of castella decreased. The hardness and springiness of castella did not show significant differences. In the sensory evaluation, crust color, crumb color, aroma and moistness did not show significant differences among samples while sweet taste, and chewiness were highest in the control group. The overall acceptability of castella added with 5% Panax ginseng sprout powder was the highest. Therefore, the results suggest that castella added with 5% ginseng sprout powder could be helpful for improving physical quality and taste.

Pound cake were prepared by addition of 0, 5, 10 and 15% powder to the flour of basic formulation. The pH of the batter and cake decreased with increasing perilla leaves powder concentration. The baking loss rate of the pound cake tended to increase by 7.13~7.42%. The height of pound cake added with perilla leaves powder decreased with increasing powder concentration. The lightness, redness, and yellowness values were significantly decreased with increases in perilla leaves powder except for redness of pound cake crumb. The pound cakes containing 5% perilla leaves powder had acceptable sensory evaluation, such as flavor, taste, moistureness, and overall preference. The hardness and gumminess tended to increase, while springiness and cohesiveness decreased with increases in perilla leaves powder. The retrogradation degree of pound cake prepared with perilla leaves powder for 7 days at $25^{\circ}C$ was higher than the control but there were no significant differences. For the antioxidative activity measured by DPPH (2,2-diphenyl-1-picrylhydrazyl) radical scavenging activity, pound cake added with 10% and 15% added perilla leaves powder showed high antioxidant activities. The results exhibited that adding the perilla leaves powder into the pound cake increased antioxidant activity with the highest quality improvement obtained by incorporating 5% (w/w) of perilla leaves powder into the pound cake formula.

The study investigated on quality characteristics of pan breads prepared with 0, 1, 3 and 5% flowering cherry (Prunus serrulata L. var. spontanea Max. wils.) fruit powder. The pH of dough and bread decreased with the addition of flowering cherry fruit powder, whereas the weight of bread increased. The volume, specific volume and baking loss rate of the breads decreased as flowering cherry fruit powder levels increased. The volume of dough during fermentation of bread containing flowering fruit cherry powder was smaller than those of the dough without flowering cherry fruit powder. Lightness (L) and yellowness (b) of breads crumb and crust color were decreased as the concentration of flowering cherry fruit powder increased; however, the redness (a) was increased. In the texture analyzer measurement, hardness and chewiness of the breads were significantly increased by adding the powder but cohesiveness was decreased. There was no significant difference in springiness. The antioxidative activity measured by DPPH radical scavenging activity of bread increased as the concentration of flowering cherry fruit powder increased. The bread containing 3% flowering cherry fruit powder has acceptable sensory properties. such as color, smell, taste, chewiness, texture and overall acceptability. The results exhibited that adding the flowering cherry fruit powder into the bread increased antioxidant activity, and the highest quality improvement was obtained by incorporating 3% flowering cherry fruit powder into the bread formula.

The aims of this study were to investigate the quality characteristics of yellow layer cake added with Sparassis crispa powder that were abundant in dietary fiber, and also to determine the most suitable amount of added S. crispa powder. Dried powder of S. crispa containing 61.8 g/100 g insoluble dietary fiber was added to the cake batter in Baker's percentage of 1%, 2%, 4%, and 8%. Cake batter containing 1% and 2% S. crispa powder showed similar pH, specific gravity, and viscosity values to the batter without S. crispa powder (control). As the amount of added S. crispa power increased, the volume, specific volume, baking loss, and brightness (for both crust and crumb) of the cake containing the powder tended to decrease. A greater amount of added S. crispa powder resulted in a decrease in hardness, gumminess, and chewiness of the cake containing the powder and also reduced the changes in hardness of the cake during 8 days of storage. The sensory analysis showed that cake containing 2% S. crispa had several desirable kinds of sensory attributes, such as color, flavor, taste, and texture compared to the control; whereas an addition of more than 2% S. crispa deteriorated the sensory quality of the cake. These results suggest that the most suitable amount of added S. crispa powder for preparing yellow layer cake was 2% in Baker's percentage.
The purpose of this study was to analyze the flavors of four fresh herbs(rosemary, basil, applemint, and majoram) and when they are fried, boiled, baked, and microwaved. Among the 18 flavors in rosemary, 37.40% was composed of ${\alpha}$-pinene(flavor of refreshing pine). The next highest composition of rosemary was 1,8-ci-neole(fresh, cool, sweet flavor) with 23.34%. In basil, 1,8-cineol had the most composition with 32.9%, and next was 3-hexen-1-ol(delicate floral fragrance) with 20.6%. When it was boiled, it barely had loss and when it was fired, only 10% of its flavor was left. Trans-${\beta}$-ocimene(camphoraceous and pine-like flavor) composed applemint with 16.66% and ${\beta}$-pinene(dry-woody and resinous-piney flavor) with 12.99%. Majoram was composed with 21 differrent flavors, 18.80% was composed of sabinene(spicy, woody-herbaceous flavor) and ${\gamma}$-terpine(citrusy flavor) composed 15.61% of majoram. Majoram had more flavor left when cooked compared to other herbs. In conclusion, rosemary and majoram had the most stability than other herbs, and boiling and baking left more flavor than frying them.
Radicchio (Cichorium intybus L.) is widely known to have antioxidant, anti-cancer, and digestion-promoting effects. Antioxidant activity and sensory characteristics of sponge cakes made with radicchio powder were investigated in this study. Sponge cakes were made with freeze-dried radicchio powder added to the flour at concentrations of 1, 3, 5, and 7%. As the amount of radicchio powder increased, the specific gravity of radicchio-containing sponge cakes significantly increased. pH value did not significantly differ between groups. Moisture content decreased from 30.72% (control) to 28.68% (7% radicchio) and loss of mass during baking increased from 7.11% (control) to 9.36% (7% radicchio). L (brightness) and b (yellowness) of sponge cakes decreased while redness increased. Hardness and chewiness decreased as concentration of radicchio powder increased. Springiness and cohesiveness did not significantly differ between any of the groups. Total polyphenol contents ranged from 0.12 to 0.31 mg GAE/g. DPPH scavenging activity significantly increased as the amount of radicchio powder increased. Overall acceptability of sensory experience measured on a 7-point scale was highest in the 3% radicchio cakes (5.35). In conclusion, the addition of 3% radicchio powder improves the sensory qualities of radicchio sponge cakes.
