The quality characteristics of noodles made from domestic Korean wheat flour added with 0, 1, 3, 5% cactus Chounnyuncho (Opuntia humifusa) powder were investigated. The water absorption and peak time of dough, as determined by farinography, increased with higher cactus powder content. Stability and elasticity of dough decreased as fermentation proceeded. Cooking characteristics of noodles made from dough such as weight, water absorption, and volume decreased with higher cactus powder content. The turbidity of cooked water increased significantly with 5% cactus powder content. For color test, L-value decreased while a-value and b-value increased with higher cactus powder content. In texture analyses, hardness, adhesiveness, springiness, cohesiveness, and gumminess increased with higher cactus powder content. In the sensory test, noodles containing 3% cactus powder were the most preferred.

Soybean powder is a readily available ingredient that is consumed daily as a functional food material. Furthermore, red Ginseng is an herb with various physiological effects. Therefore, in this study, we examined the physiochemical characteristics of Soybean Dasik samples prepared with different amounts of added red Ginseng gel, including Hunter's color values, mechanical characteristics, and sensory qualities. The results of each analysis are as follows. For the soybean Dasik stored at room temperature($20^{\circ}C$), luminance was reduced as the amount of added red Ginseng gel increased. In addition, Hunter's a and b values were significantly higher in Dasik samples that did not contain red Ginseng gel, as compared to those with increasing red Ginseng gel content. The mechanical properties of the Dasik were also measured at room temperature showing significant differences between samples(p<0.001) for hardness, springiness, cohesiveness, gumminess, and chewiness. In the sensory evaluation, 3 rounds of testing indicated that sweetness acceptance scores were significantly reduced(p<0.001) as the amount of added red Ginseng gel in the Dasik increased. Finally, overall quality was significantly different between the samples(p<0.001) and acceptance scores increased with increasing red Ginseng gel content.

The purpose of this study was to investigate replacing possibility of sucrose by sugar alcohols and to establish the optimum formula for the development of sugar cookies. The characteristics of sugar cookies prepared with xylitol, maltitol, lactitol, isomalt substituted for 35, 50, 75, 100% of sucrose were examined through physical measurement and sensory evaluation. The spread ratio of cookies containing sugar alcohols except xylitol was superior to that of control cookies(sucrose 100%) and the use of lactitol increased the spread ratio of cookies. The specific gravity of cookies containing sugar alcohols except xylitol was lower than that of control cookies. Therefore spread ratio was in inverse proportion to specific gravity. As the proportion of sugar alcohols increased in cookie formula, surface color of cookies was getting lighter than that of control cookies. Especially cookies containing xylitol, maltitol was getting lighter as the levels of replacement increased. Overall quality of cookies with sugar alcohols containing sensory analysis was superior to that of control cookies.

With the advancement and diversification of the bread industry, eco-friendly products with less sugar and salt, and containing functional ingredients are being developed. To develop healthy bread, Korean pine leaf powder was added in different proportions (0%, 1%, 3%, 5%, and 7%), and the quality characteristics of the bread, namely height, moisture, color value, texture, antioxidant property, and sensory characteristics were evaluated. As the amount of leaf powder was increased in the bread, L-value in the range of 53.45~85.05 (p<0.001) and adhesiveness in the range of 0.13~0.32 mJ (p<0.001) decreased significantly, whereas b-value in the range of 16.75~30.74 (p<0.001), total polyphenol content in the range of 466.83~669.13 ug/mL, ABTS- in the range of 0.46~43.23%, DPPH-radical in the range of 1.39~45.76%, scavenging capacities (p<0.001), color in the range of 3.27~5.40 (p=0.017) and texture in the range of 4.33~4.80 (p=0.006) preferences increased significantly. This study could increase the utilization of Korean pine leaf and the production of healthy food with antioxidant properties.

This study was performed to investigate the physiochemical and sensory characteristics of Kimchi with added Houttuynia cordata Thunb(HC). According to measurements for physicochemical characteristics, the three groups of tested Kimchi(HC juice, HC powder, control) did not show any significant differences in pH and hardness. However, the acidity of the Kimchi with added HC juice was found to be significantly higher. Regarding lightness, L values were not different among the three groups, while a and b values showed significant decreases. In descriptive analysis, Kimchi redness was lowest in the HC juice group, and difference in redness was identified between the HC juice and powder groups. One survey indicated that the Kimchi with added HC juice had a unique odor, but no difference was found between the HC powder group and the control group. Also, a survey on preference characteristics indicated there were no differences between the three groups. For the saltiness and acidity of the Kimchi with added HC, there was a significant negative correlation(p<0.05), in which stronger saltiness lower acidity. On the other hand, acidity and HC odor showed a significantly positive correlation(p<0.05). Furthermore, the L value showed a significantly negative correlation(p<0.05) with HC odor.

The aims of this study were twofold: i) to investigate changes in the sensory characteristics and consumer preference of diluted espresso drinks according to different dilution rates; ii) to compare the physicochemical characteristics between diluted espresso coffees, using the preferred coffee of this study and commercial products from coffee shop chains. Descriptive analysis using a 15 cm line scale, and a consumer preference test were carried out by 6 trained panelist,; and 50 consumers (F=39, M=11), respectively. Appearance (transparent, black), odor (bitter, rich), taste (bitter, burnt, astringent, umami, sour), and mouth-feel (aftertaste, body, coarseness, oily, roughness, soft-swallowing) were significantly different among the 3-, 5-, 7-, 9-, and 11-times dilution rates. In particular, the sensory characteristics associated with mouth-feel showed obvious differences with the dilution rates. In the consumer preference test, the 9-times diluted espresso had the highest preference, whereas the 3-times diluted espresso showed the lowest preference. Moreover, the 9-times diluted espresso demonstrated similar physicochemical characteristics such as pH, sugar content, and total solid content to those of the commercial diluted espresso drinks from coffee shop chains. In conclusion, the sensory characteristics and consumer preference of the diluted espressos were influenced by the dilution rates.

In this study, we attempted to understand the cultural characteristics of Korean food based on a traditional understanding of a Korean novel. To achieve this, food characteristics related to "Gaesung's foods" were analyzed in the representative Korean literary work Mimang. Mimang is a novel, from the latter era of the Chosun Dynasty to the Korean War in the Gaesung area. From that novel, it was discovered that first daily foods in the Gaesung area of the 19th century were various stored fermented foods. The second was the devotion of Gaesung food's cooking process and formal attire. The third was reflected in the economic abundance and the splendor of Gaesung food courts. The fourth was a modern public restaurant in Gaesung, an economic and commercial city. Another historically significant food found in Mimang was Gaesung ginseng.

Purpose: The objective of this study was to investigate the quality characteristics of pork and beef meat according to species (pork: modern genotype pork, Korean native black pork; beef: Holstein, Korean native cattle) and cuts (pork: shoulder, ham, loin; beef: loin, tenderness, round). Methods: The moisture content, protein content, fat content, ash content, fatty acid compositions pH, whater holding capacity, cooking loss, shear force, color, and sensory characteristics were measured in triplicate. Results: The moisture content, pH, cooking loss, and shear force of modern genotype pork were significantly higher than the Korean native black pork; in addition, the moisture content of loin was significantly higher than shoulder and ham. The fatty acid compositions for different parts of pork showed no significant differences. Among the sensory characteristics, the parameters of pork were not significantly different. The moisture content of Holstein was significantly higher than Korean native cattle. The fatty acid composition of beef could not confirm the specific differences. Water holding capacity of Korean native cattle was higher than Holstein, while cooking loss of Korean native cattle was lower than Holstein. Overall acceptability scores of Korean native cattle was higher than Holstein. Conclusion: The study results of several parameters in selected raw meat samples provide useful information for developing new strategies to improve the quality of meat products consumption.

In this study, we investigated the quality characteristics of madeleine combined with lyophilized red snow crab Chionoecetes japonicus leg-meat powder (CM). The madeleine was prepared by the addition of wheat flour containing 0, 1, 5, 10, 15 and 20% concentrations of CM. Moisture content, pH, and baking loss rate did not differ significantly among groups. Light coloration significantly decreased in a dose-dependent manner, while red and yellow coloration significantly increased. Hardness, chewiness and gumminess significantly increased in a dose-dependent manner, while cohesiveness, springiness and adhesiveness did not differ from CON (madeleine containing 0% CM). In terms of sensory characteristics, appearance and color did not differ compared to CON, while taste, flavor and overall preference increased in a dose-dependent manner, with CM10 having the highest score among the groups. The present study assesses the potential of this improved formula as a convenience food.
