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.

This study was performed to examine the quality characteristics of the curd yogurt with different contents (0.5$\sim$2.0% (w/v)) of cherry powder (obtained from freeze-dried fruit of Prunus serrulata L. var. spontanea Max. wils.). Yogurt was fermented with two kinds of lactic acid bacteria (Streptococcus thermophilus, Lactobacillus bulgalicus) at $40^{\circ}C$ for 18h. During the period of 14 days of storage ($4^{\circ}C$, 14 days), acid production (pH and titratable acidity) of the yogurts increased significantly with the addition of cherry powder. The sugar content of the yogurts prepared with cherry powder increased but cherry powder yogurts presented lower viscosity values than the control. Hunter color values, lightness (L) and yellowness (b) of yogurt colors decreased as the concentration of cherry powder increased, whereas the redness (a) increased. Lactic acid bacteria of yogurts increased with the addition of cherry powder and all samples had increasing levels of lactic bacteria over the storage period. The sensory properties, such as flavor, taste, viscosity, and overall acceptability, of the yogurts containing the 1.0% cherry powder were superior to the control sample. Consequently, the optimal quality achieved in these experiments was yogurt with 1.0% cherry powder added.

The study investigated the quality of pound cake prepared with various concentrations of cherry powder (obtained from ground fruit of Prunus serrulata L. var. spontanea Max. wils.). Pound cake was evaluated for their sensory property and physical quality stored for 10 days at $25^{\circ}C$. The pH of the batter decreased with rising cherry powder concentration. The specific loaf volume and height decreased (from 2.95 to $2.60\;cm^3/g$) with increasing in cherry powder. The baking loss rate of the pound cake tended to increased by $11.47{\sim}12.67%$, but with no significant differences. The lightness, redness, and yellowness values were significantly decreased with increases in cherry powder except for redness of pound cake crumb. As the concentration of cherry powder increased, the mechanical characteristics of the pound cake did not differ significantly. The hardness tended to increase, while adhesiveness and springiness decreased with increases in powder. The retrogradation degree of pound cake prepared with cherry powder 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 prepared with 10% and 15% added cherry powder showed high antioxidant activities. The pound cakes containing 10 and 15% cherry powder had acceptable sensory properties, such as flavor, taste, softness, moisture, and overall acceptability. The results exhibited that adding the cherry powder into the pound cake increased antioxidant activity with the highest quality improvement obtained by incorporating 10% (w/w) of cherry powder into the pound cake formula.

This study evaluated the physicochemical and sensory characteristics of cookies containing various concentrations (0, 3, 6, and 9%) of cherry powder (obtained from ground fruit of Prunus serrulata L. var. spontanea Max. wils.). The pH of dough decreased with the addition of cherry powder, whereas the density of dough increased. The spread factor of control samples also evidenced significantly higher values than the other samples. The results of a hardness assessment demonstrated that the addition of cherry powder exerted a significant effect on cookie hardness. Lightness (L) and yellowness (b) of cookie color decreased as the concentration of cherry powder increased, whereas the redness (a) increased. The antioxidative activity measured by DPPH radical scavenging activity of cookie increased as the concentration of cherry powder increased. The cookies containing the 3 and 6% cherry powder had acceptable sensory properties, such as color, smell, taste, hardness, crispness, and overall acceptability. The results exhibited that adding the cherry powder into the cookie increased antioxidant activity, and the highest quality improvement was obtained by incorporating the 3 and 6% of cherry powder into the cookie formula.

The purpose of this study was to investigate the effect of adding various concentrations of cherry powder(obtained from freezed dried fruit of Prunus serrulata L. var. spontanea Max. wils.) on the physicochemical, antioxidant, and sensory characteristics of jelly. The pH of the jelly decreased significantly with the addition of cherry powder. The sugar content of the jelly increased significantly (p<0.05) with cherry powder added more than 7%. The Hunter color L-values decreased significantly (p<0.05) by the addition of cherry powder, and a- and b-values increased by the addition of cherry powder compared to the control, but there were no constant changes with increasing amounts of cherry powder. For the textural characteristics, the addition of cherry powder significantly (p<0.05) increased the hardness, chewiness and gumminess but there were no significant difference (p<0.05) in the springness and cohesiveness. The antioxidative activity measured by DPPH (2,2-diphenyl-1-picrylhydrazyl) radical scavenging activity of jelly increased as the concentrations of cherry powder increased. The jellies containing 1 and 5% cherry powder had acceptable sensory properties, such as color, flavor, taste, texture, and overall quality. In consideration of the antioxidant properties and sensory characteristics, the highest quality improvement was obtained by adding 5% (w/w) of cherry powder into the jellies.

This work was aimed to evaluate supplementation of honey as sole carbon source on the fermentation characteristics of wine fermented with fruit of flowering cherry and honey(flowering cherry-honey wine). Physiochemical changes of flowering cherry-honey wine(2 L) were investigated during 30 days in fermentation by strain of Saccharomyces bayanus (EC-118). At the beginning of fermentation, fructose was most abundant sugar then glucose and sucrose were followed. As fermentation proceeded, utilization of glucose by S. bayanus (EC-118) was faster than fructose, so that the ratio of fructose/glucose was increased. During fermentation for 30 days, pH and viable yeast count was changed rapidly between 0 to 5 days, while $^{\circ}Brix$(%) decreased gradually for 30 days. Final total titratable acidity, pH, $^{\circ}Brix$(%) and ethanol content of flowering cherry-honey wine were 0.43%, pH 3.5, $9.7^{\circ}Brix$(%) and 14%, respectively. Our finding demonstrate that flowering cherry-honey could be benefical supplements for wine production.

Cherry powder (obtained from ground fruit of Prunus serrulata L. var. spontanea Max. wils.), which is a natural functional material, was used in muffin manufacturing at different concentrations from 0, 3, 5, 7, and 10% (w/w). Muffin was evaluated for their sensory property and physical quality. The antioxidative activity measured by DPPH (2,2-diphenyl-1-picrylhydrazyl) radical scavenging activity of muffin increased as the concentrations of cherry powder increased. As the concentration of cherry powder increased, the mechanical characteristics of the muffin, such as hardness increased, but gumminess and chewiness decreased. Lightness (L) and yellowness (b) of muffin decreased as the concentration of cherry powder increased, whereas the redness (a) increased. The muffins containing 3, 5, 7, and 10% cherry powder had acceptable sensory properties, such as color, flavor, taste, softness, moisture, and overall acceptability. The results exhibited that adding the cherry powder into the muffin increased antioxidant activity. The highest quality improvement was obtained by incorporating 5% (w/w) of cherry powder into the muffin formula.

Cherry powder (obtained from ground fruit of Prunus serrulata L. var. spontanea Max. wils.), which is a natural functional material, was used in dark & white chocolate manufacturing at different concentrations from 0, 3, 6 and 9%. The moisture content of the cherry powder chocolate was significantly higher than the control; however, pH of chocolate was decreased significantly with the addition of cherry powder. Lightness (L), redness (a) and yellowness (b) of chocolate decreased as the concentration of cherry powder increased. The hardness was decreased with the increasing cherry powder. As the amount of cherry powder increased, total phenol content, DPPH radical scavenging activity increased. Color, smell, taste, hardness, texture and overall acceptability of chocolate were significantly higher in the chocolate containing 3% cherry power. Results suggest that the optimal amount of cherry powder added in the manufacturing of chocolate was 3% of the total weight.

This study was performed to investigate the antioxidant activity of cherry added into meat products. Water and methanol were used to extract the antioxidant compounds from cherry. Total phenolic compounds of the methanol and water extract of cherry were 2.17 g/100 g and 2.77 g/100 g, respectively. The 1,1-diphenyl-2-picrylhydrazyl radical scavenging activity of methanol extract showed similar activities to those with ascorbic acid at all concentrations (from 0.1% to 2.0%). Especially, water extract of cherry showed similar activity to those of ascorbic acid (AA), and methanol extract, when 2% of cherry extract was added. The reducing power of cherry was not comparable to those with AA, however no differences in reducing power were observed between the water and methanol extract. The iron chelating ability of cherry was observed in the range of 17.8-94.0% at both water and methanol extracts. An increased iron chelating ability was observed with increased concentration up to 2%. Iron chelating ability for water extract of cherry tended to be lower than those with methanol extract. After pork patties were manufactured with methanol extract of cherry at 0.5 and 1.0%, physicochemical properties, lipid oxidation and microbial changes of patties were measured. The addition of methanol extract of cherry reduced pH, brightness, redness, yellowness and thiobarbituric acid reactive substance (TBARS). During 14 d of storage, pH, TBARS and microbial counts were increased, while redness and yellowness values were decreased. Since the addition of methanol extract of cherry lowered TBARS during storage, it could be used as a natural antioxidant in meat products.

Physicochemical properties of flowering cherry (Prunus yedoensis, Prunus sargentii, Prunus lannesiana, Prunus cerasus) fruits were evaluated. The moisture contents were the highest in fruits of Prunus cerasus; crude protein ranged from $0.19{\sim}1.49%$ and crude fat ranged from $1.00{\sim}2.66%$. The fruits of Prunus lannesiana included higher contents of crude ash compared with those of other cultivars. The mineral contents of Prunus lannesiana fruits were the highest in Ca, K, Mg, Fe, and Mn. The amino acid contents of only methionine was the highest in fruits of Prunus sargentii (1.64 mg/L). Other amino acids were the highest in fruits of Prunus cerasus. The Brix value was the highest in fruits of Prunus yedoensis, followed by fruits of Prunus sargentii, Prunus lannesiana, and Prunus cerasus. Organic acid contents ranged from $3.42{\sim}4.18%$. Anthocyanin contents were the highest in fruits of Prunus sargentii in methanol extract. Therefore oriental cherry commensurates with development of nature pigment and functional foods. Especially, Prunus cerasus was greater than other cultivars.
