Effects of added green tea powder and Angelica keiskei powder on the quality characteristics of Yukwa were examined for the purpose of improving functioanality and variety of Yukwa, and usage of green tea Powder and Angelica keiskei. Dietary fiber contents of green tea powder were 5.2% soluble dietary fiber, 22% insoluble dietary fiber, while Angelica keiskei contained 28.9% soluble dietary fiber, 29.6% insoluble dietary fiber. Expansion rate of yukwa was 3,675% for control and the rates were slightly decreased as the addition level increased. Although Yukwas added 6% green tea and angelica keiskei powder were harder than the others when determined by rheometer, sensory evaluation results showed that hardness and mouthfeel were soft without any significant difference among the control and experimental samples. And internal structure of 4 and 6% green tea powder and those added angelica keiskei at three levels were evaluated by sensory panel as moderately compact. Overall acceptability of yukwa added 2% green tea Powder was the best of all while yukwas added angelica keiskei at three levels were evaluated as good. The results of peroxide value and TBA value showed that green tea powder had stronger antioxidative property than angelica keiskei. In conclusion addition of green tea powder by 2% level and angelica keiskei powder up to 4% would give us beneficial effects in the aspects of functionality and storage life of yukwa without any detrimental effects on the quality characteristics of it.

This study examined the effects of Boehmerianivea powder on the functional and sensory characteristics of dumpling shell. Various dumpling shell samples were prepared with wheat flour containing different amounts of Boehmerianivea powder. The instrumental characteristics were examined and sensory evaluations were performed. According to the amylograph data, the composite Boehmerianivea powder-wheat flour samples had increased gelatinization temperatures with increasing Boehmerianivea powder content; whereas the initial viscosity at $95^{\circ}C$, viscosity at $95^{\circ}C$ after 15 minutes, and the maximum viscosity were reduced. The L, a and b Hunter's color values decreased with increasing Boehmerianivea powder content. In addition to the cooked weight, the cooked volume and turbidity of dumpling shell increased with increasing level of Boehmerianivea powder. In terms of the textural characteristics, the addition of Boehmerianivea powder increased the chewiness, smoothness and adhesiveness. The DPPH free radical scavenging activity increased significantly with increasing content of Boehmerianivea powder (p<0.05). Finally, the results of the sensory properties indicated that 5% Boehmerianivea powder had the highest scores. These results suggest that Boehmerianivea powder can be applied to dumpling shells to achieve high quality and functionality.

Premix frying powders were prepared by supplementation with 0%, 3%, 6%, 9%, or 12% egg white powder. The following quality characteristics of the fried batter were assessed: proximate composition and amino acid content of premix frying powder; viscosity and pick-up ratio of frying batter; moisture content, lipid content, color, texture and DPPH radical scavenging activity; and sensory evaluation items. Addition of egg white powder in place of wheat flour resulted in lower moisture content (p<0.01) and lower carbohydrate content (p<0.001), higher crude protein content (p<0.001), higher ash protein content (p<0.001), and higher amino acid content (p<0.01) in the premix frying powder. Lower viscosity and higher pick-up ratio (p<0.001) of the frying batter were observed. The resultant fritters had the higher moisture content and higher lipid content (p<0.001). They also showed the lighter color, and had lesser redness and yellowness (p<0.001). Considering texture, the fritters were harder, had higher fracturability and higher adhesiveness (p<0.001), lower springiness (p<0.001), were less chewy (p<0.01), and had lower cohesiveness (p<0.001). Examination of DPPH radical scavenging activity showed higher antioxidant activity (p<0.001) upon addition of egg white powder. Sensory evaluation of the fried batters showed the best outcomes for the group containing 6% white egg powder, in terms of appearance (p<0.05), flavor (p<0.001), taste (p<0.01), texture (p<0.01), and overall quality (p<0.001). Based on the results of this research, we postulate that the addition of 6% egg white powder to premix frying powder will not only improve customer preference and product quality but also enhance the nutrition and functionality of the product.

This study investigated the quality characteristics of the Seolgiddeok samples prepared with various amounts(0, 0.5, 1.0 and 2.0%) of Paecilomyces japonica powder by examining proximate compositions, color, texture and sensory quality. The composition of the Paecilomyces japonica powder was measured as follows: moisture(7.40%), crude protein(55.77%), crude lipid(7.1l%), and crude ash(5.39%). With increasing Paecilomyces japonica powder content, the moisture and crude protein content of the Seolgiddeok increased; however crude fat and ash contents decreased. In terms of color, the lightness of the Seolgiddeok decreased and yellowness and redness increased with increasing amounts of Paecilomyces japonica powder. Among textural characteristices hardness, cohesiveness, and gumminess were decreased, but springiness increased according to the addition level of Paecilomyces japonica powder. For the sensory evaluation, the overall quality of the SP-l.0% group was not significantly different than the control group(SP group). In conclusion, the optimal addition amount of Paecilomyces japonica powder for Seolgiddeok is proposed as 1% of total weight.

The principal objective of this study was to evaluate the quality characteristics of dried noodles when different concentrations of Lotus root powder were added to the wheat flour. The cooking quality, mechanical textural properties, and viscosity were measured, and a sensory evaluation was conducted with the prepared noodles. The gelatinization points of the composite Lotus root powder-wheat flours were shown to have increased and the viscosity at $95^{\circ}C$, viscosity at $95^{\circ}C$ after 15 minutes, and maximum viscosity values of those samples were reduced, as the Lotus root powder content was increased as measured via amylography. As increasing amounts of Lotus root powder were added, the L and b values were reduced, and the color values, weight, and volume of the cooked noodles increased, as did the turbidity of the soup. With regard to the textural characteristics, the Lotus root powder additive increased hardness and reduced adhesiveness, cohesiveness, and springiness. Overall, the noodles prepared with 15% Lotus root powder were preferred more than the other noodles, according to the results of our sensory evaluation.

This study was conducted to investigate the quality of white pan breads as affected by various concentration of Cordyceps powder. Breads were prepared by addition of 0, 1, 2 and 3% of Cordyceps to flour of basic formulation. The moisture content of white pan breads decreased with increasing Cordyceps powder concentration. The pH of white pan breads also decreased with increasing Cordyceps powder concentration. In color values, with increase of Cordyceps powder concentration, L value decreased and a value increased in the crumb. The weights of breads cooled decreased with increasing Cordyceps powder concentration. The volume and height of dough decreased with increasing Cordyceps powder concentration. However, the specific volume and yield of dough were not significantly different among groups. The baking loss rate was higher in the breads with Cordyceps powder than in the control. In the texture characteristics, hardness and chewiness of breads significantly increased with increasing Cordyceps powder concentration and adhesiveness increased. In the sensory evaluation, when compared to the control, the breads added to 1% of Cordyceps powder was superior to in color and flavor, while was similar to texture and taste.

This study was conducted to investigate the quality characteristics of Sulgitteok prepared with different ratios of lotus leaf powder, over for 4 days of storage. As the amount of lotus leaf powder increased, the moisture contents of the lotus leaf Sulgitteok decreased; however, this was not consistent for all samples during storage. As the content of the lotus leaf powder increased, the L-values of the lotus leaf Sulgitteok significantly decreased, and the a- and b-values also significantly increased at day 0. The L- and a-values did not show large differences with storage. The total cell count of the lotus leaf Sulgitteok prepared with the 4% lotus leaf powder (LL4) was considerably lower than the other samples at 2 days of storage, indicating that microorganisms were inhibited by increasing amounts of lotus leaf powder. The hardness, gumminess, and chewiness of the lotus leaf Sulgitteok decreased as the amount of lotus leaf powder increased; however, they increased as storage time passed. Increasing amount of lotus leaf powder and the storage time resulted in greater reductions in adhesiveness. Springiness was not significantly different according to the amount of added lotus leaf powder or the storage time. Increasing storage time caused cohesiveness to decreased in all samples except LL2. Also, the results of the sensory evaluation showed that the LL2 lotus leaf Sulgitteok had the highest scores. In conclusion, the lotus leaf Sulgitteok prepared with the 2% lotus leaf powder (LL2) was superior.

This study was conducted to investigate the effects of chlorella powder on quality characteristics of maejakgwa (a Korean traditional cookies). Maejakgwa was prepared with different amounts of chlorella powder (in ratios 0, 1, 2, 3, and 4% of flour quantity). The moisture, crude ash, crude protein, and crude lipid contents of used chlorella powder were 2.38, 7.25, 65.95, and 0.95% respectively. The pH of maejakgwa dough decreased significantly as the level of chlorella powder increased; however, density of the batter, spread factor values, and moisture contents of the groups increased significantly with higher level of the chlorella powder. In addition, Hunter's color L, a, and b values decreased significantly with increasing amounts of chlorella powder. In the texture meter test, hardness increased according to increasing concentration of chlorella powder. Finally, maejakgwas containing 1~2% chlorella powder had the highest sensory evaluation. From these results, we suggest that chlorella powder is a good ingredient for increasing consumer acceptability as well as functionality of maejakgwas.
