This study evaluate the antioxidant activity and quality characteristics of muffins prepared with the addition of Cirsium nipponicum powder in the ratio of 0, 2, 4, 6, and 8% and confirm the possibility of using Cirsium nipponicum as a functional food. As the proportion of Cirsium nipponicum powder increased, the specific gravity of the muffins increased while their height, specific volume, moisture content and pH decreased. The baking loss rate of the samples prepared with the addition of Cirsium nipponicum powder was higher than in the control group. The 'L' and 'b' values decreased with the increase in the Cirsium nipponicum powder content, while the 'a' value increased. The evaluation of texture showed that hardness, chewiness, and gumminess increased with an increase in the Cirsium nipponicum powder content. As per the results of the consumer acceptability test, the 4-6% Cirsium nipponicum powder group showed higher scores than the other groups in the characteristics of color, flavor, taste, and texture, and the 4% group secured the highest score for overall acceptance. Also, with the increasing addition of Cirsium nipponicum powder, the antioxidant activity levels increased, as indicated by the total phenolic content, DPPH, and ABTS radical scavenging activities and reducing power. Based on these study results, muffins prepared with the addition of 4% of Cirsium nipponicum powder showed the best functional and sensory qualities.

In this study, we assessed the antioxidant activities and quality characteristics of cookies containing various concentrations (0, 1, 3 and 5%) of Eleutherococcus sessiliflorus leaf powder. Antioxidant activity was estimated based on DPPH free radical scavenging activity and total content of phenolic compounds in Eleutherococcus sessiliflorus leaf powder and cookies. The quality characteristics of Eleutherococcus sessiliflorus leaf cookies were estimated based on spread factor, loss rate, leavening rate, color, texture and sensory evaluation, polyphenol contents, DPPH free radical scavenging activity, as well as spread factor of cookies significantly increased. L value, b value and hardness of cookies decreased with increasing Eleutherococcus sessiliflorus leaf powder content. Finally, the sensory evaluation showed the highest scores for cookies containing 3% Eleutherococcus sessiliflorus leaf powder. From these results, we suggest that Eleutherococcus sessiliflorus leaf is a good ingredient for increasing consumer acceptability as well as the functionality of cookies.

Silkworm powder's thermal property is an important factor for its storage and marketing. This study examined the effect of edible enzyme on the thermal property of silkworm powder using Thermogravimetric Analysis (TGA) and Differential Scanning Calorimetry (DSC). Results of the TGA showed that regardless of the enzyme treatment, the weight loss patterns of silkworm powders exhibited 3 step thermal property deterioration at approximately $80^{\circ}C$, $280^{\circ}C$, and $480^{\circ}C$ due to water evaporation and thermal degradation. This is similar with the DSC which also resulted in all samples two endothermic peaks attributed also to water evaporation and thermal degradation. These results indicated that the use of enzyme such as protease and cellulase might not affect significantly the thermal properties of silkworm powder.

This study was conducted to investigate the effect of chestnut inner shell powder on antioxidant activity and the quality characteristics of cookies. Cookies were prepared with different amounts of chestnut inner shell powder(in ratios of 0, 0.5, 1, 3 and 5% to the flour quantity). The antioxidant activity was estimated by DPPH free radical scavenging activity and the total phenol content in chestnut inner shell powder and cookies. For analyzing quality characteristics, bulk density and pH of the dough, spread factor, loss rate, leavening rate, color, texture profile analysis, and sensory evaluations were measured. The spread ratio, a values, total phenol contents and DPPH free radical scavenging activity of cookies significantly increased with increasing chestnut inner shell powder(p<0.001), while the pH of the dough, L values and b values of the cookies significantly decreased with increasing chestnut inner shell powder content(p<0.001). The consumer acceptability score for the 3% chestnut inner shell cookie groups ranked significantly higher(p<0.01) than those of the other groups in overall preference, flavor, taste and color. From these results, we suggest that chestnut inner shell is a good ingredient for increasing the consumer acceptability and the functionality of cookies.

The authors derived the criteria on the process parameters of laser depositions with metal powers(SUS316L & IN718) by evaluating the surface and cross-section properties of the deposition layers. The surface characteristics of the deposition layer are investigated through optical microscopy by controlling the process parameters of laser output, powder feeding rate and gas feeding rate. The cross-section characteristics were also analyzed after polishing and chemical etching process. As the gas feeding rate increased, the amount of powder loss increased and the difference in the dilution ratio and heat affected zone depending on laser outputs was observed. In addition, the powder feeding rate used in the experiment did not interfere with the energy absorption of the base material.

This study was carried out to evaluate the quality characteristics of cookies added with various concentrations (0, 1, 3 and 5%) of ginseng leaf powder. The pH of the cookies significantly decreased with increased ginseng leaf powder concentrations (p<0.05), but the density of cookies showed no significant differences. Spread factor, loss rate, and leaving rate of cookies decreased according to the amount of added ginseng leaf powder. The lightness and yellowness of cookies decreased as the concentration of the ginseng leaf powder increased whereas no significant difference in the redness was found with increased ginseng leaf concentration. In the texture analysis, the hardness of the cookies increased according to the concentration of ginseng leaf. DPPH free radical scavenging activity of the cookies significantly increased with increased ginseng leaf concentration (p<0.05). In the sensory evaluation, sensory scores for color, taste and overall acceptability were highest in the 3% ginseng leaf cookies. Thus, our results suggested that the optimum amount of ginseng leaf powder to add to cookies was 3%.

This study was conducted to find out the bakery processing suitability of maca and to develop rice-based processed foods. We investigated the antioxidant activity and physicochemical properties of rice cookies prepared with the addition of maca (Lepidium meyenii) powder (1%, 2%, 3%, and 4% of the total materials). We observed an increase in the total polyphenol and flavonoid content, and DPPH-ABTS⁺ radical scavenging activity of the rice cookies as the proportion of added maca powder increased (p<0.05). The quality characteristics such as the "a" value, "b" value, and the hardness of the cookies increased with an increase in the proportion of maca powder (p<0.05) in the cookie, whereas the moisture content, pH of the dough, spread ratio, loss rate, leavening rate, and "L" values showed a significant decrease (p<0.05). In the sensory evaluation results, consumer acceptability showed a significantly higher value in the 2% maca cookie group (p<0.05), and the characteristic intensity rating (color, flavor, bitterness) increased as the proportion of maca added to the cookie increased (p<0.05). Therefore, this suggests that adding 2% maca powder as the functional ingredient in rice cookies can result in rice bakery products with excellent qualities.
