The study analyzed the antioxidant and whitening activities of fractions from hot-air-dried Allium hookeri (HADAH). The total polyphenol contents in fractions from HADAH extract showed the highest value ($171.07{\pm}7.55mg/g$ GAE) in ethyl acetate fraction of roots. Antioxidant activities of leaf and root parts were significantly higher in the ethyl acetate fraction. HADAH showed higher whitening activity (n-hexane fraction of leaf; 52.22% melanin production) than arbutin (65.82% melanin production), which is known as a whitening ingredient. These results suggest that HADAH extracts can be used as antioxidant and whitening materials. Thus, study of HADAH extracts showing effective whitening and physiological activities can provide efficient data for industrial use of Allium hookeri.

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.

This study evaluated the effects of low-dose X-ray irradiation treatment on quality characteristics and sensory evaluation of imported navel oranges during storage at $3^{\circ}C$ for 45 days. The samples were irradiated at doses of 0.2, 0.4, 0.6, 0.8, and 1.0 kGy, and changes in their color value, hardness, Brix/acid ratio, total sugar content, reducing sugar content, vitamin C contents, and sensory evaluation were investigated. There was no significant increase or decrease in Brix/acid ratio, total sugar content, reducing sugar content, or vitamin C content between the non-irradiated and irradiated samples. Color value of orange peels decreased with increasing levels of irradiation treatment. Color b value of orange pulp increased with an increase in irradiation dose. Difference in hardness between the non-irradiated and irradiated samples decreased at the end of storage. For the sensory evaluation after 30 days, sweetness and overall acceptability of irradiated samples at more than 0.6 kGy were low. These results suggest that X-ray irradiation under 0.6 kGy does not affect quality characteristics and sensory evaluation.

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.

The purpose of this study was to evaluate the quality of madeleine added with different concentrations (0, 1, 3, 5, and 7%) of organic ginseng leaves. The study results found that the pH and moisture of madeleine with control were higher than those of the samples. On the other hand, specific gravity of madeleine was highest at 7% leaf content (1.04). The loss rate of madeleine was not significantly different among the samples. The Hunter L, a, and b values of crust decreased as the concentration of organic ginseng leaves increased. The Hunter L and a values of crumb decreased as the concentration of organic ginseng leaves increased, whereas b values of crumb increased. The hardness of madeleine increased after addition of organic ginseng leaves, whereas adhesiveness, chewiness, gumminess, and cohesiveness of madeleine decreased. 2,2'-Diphenyl-1-picrylhydrazyl radical scavenging activity of madeleine was significantly elevated with increasing content of organic ginseng leaves (P<0.05). In a sensory evaluation, healthy image and color were highest at 3% leaf content, whereas moistness, softness, and chewiness decreased as the concentration of organic ginseng leaves increased. The flavor and overall acceptability of madeleine added with 3% organic ginseng leaves were higher than those of both control and other samples. Therefore, the results suggest that 3% organic ginseng leaves addition to madeleine could be helpful for improving physical quality and taste.

Effect of electron beam irradiation (1 and 2 kGy) on apricot was determined in order to develop preservation techniques to enhance shelf-life during 2 weeks at room temperature. Aerobic bacteria and molds/yeasts in apricot were reduced significantly with the increase of irradiation dose. Hardness of apricots decreased during storage by irradiation. Hunter's color value results showed that lightness and redness of irradiated samples were low compared with control samples. Also, sensory test resulting overall acceptability was not significantly different by 1 kGy irradiation during the storage days. Reducing sugar contents was increased gradually, and value of irradiated samples was high compared with non-irradiated sample. Organic acid contents of 2 kGy irradiated samples was not significantly changed during storage. In pH, total sugar, hydrogen donating activity and vitamin C contents, there were no significant differences between treatments. The electron beam treatment on apricots at 1 and 2 kGy did not affect pH, total sugar, hydrogen donating activity and vitamin C contents but improved microbial safety.

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.
