  • Cold buckwheat noodles with 3% vitamin D2 enriched Siitake mushroom and seaweed derived calcium (Aquacal) added as functional ingredients were developed. For the prediction of shelf-life of these cold buckwheat noodles, classified as unsterilized cooked noodles, bacterial counts and sensory evaluations were examined during 8 days under refrigerated conditions (5oC) and 8 weeks of storage under frozen conditions $(-18^{\circ}C)$. Results of bacterial count showed that cold buckwheat noodles were microbiologically safe within 6 days at the storage temperature of $5^{\circ}C$ and the shelf-life of these noodles could be extended to 8 whole weeks when stored at $-18^{\circ}C$. Apparent qualities (off-flavor and fungi development) of cold buckwheat noodles kept in $5^{\circ}C$ were not decreased within 8 days. Sensory characteristics (gloss, mushroom flavor, bitterness, chewiness and elasticity) of noodles were not changed during 8 weeks at $-18^{\circ}C$.

  • This study was carried out to investigate the possibility of improving the texture and flavor of Dasik by adding various types of sugar (syrup, honey) and flavor ingredients (omija, chija, coffee, green tea extract) to rice powder. Dasik samples were prepared, and the sensory quality and physical characteristics of those were compared. The moisture content of Dasik added with syrup was higher than that of honey. Coffee Dasik with syrup was the highest (23.6) in moisture content. In sensory quality, the omija and coffee Dasik showed the highest score in flavor quality (p<.001). Omija Dasik with honey and coffee Dasik with syrup showed the highest scores in overall acceptability (6.4, 6.2). Green tea Dasik with syrup showed the highest value in the lightness (L) of color. Omija Dasik with syrup showed the highest value in the redness (a) of color Chija Dasik was the highest in the yellowness(b) of color. In physical characteristics, the hardness was negatively correlated with the moistness, tenderness, and texture acceptability in sensory quality(p〈0.001). The cohesiveness was positively correlated with the overall acceptability in sensory quality (p〈0.01). In the relation of texture characteristics and sensory quality, the higher the moisture content, the lower the hardness and springiness were, but the higher the brittleness and the cohesiveness were(p〈.001). Overall, omija and coffee Dasik appeared to have desirable flavor, taste and overall acceptability.

  • We developed various recipes of turmeric powder (Curcuma longa L.) added to milk bread and assessed the individual effects of seven ingredients [milk ($X_1$), turmeric powder ($X_2$), bread improver ($X_3$), fresh yeast ($X_4$), butter ($X_5$), sugar ($X_6$), and salt ($X_7$)] as well as the 2-way interaction effects of the ingredients on the sensory characteristics of breads using fractional factorial design method. The center and end points of each component were determined via literature review and multiple test baking. Seven trained sensory test panels evaluated the outside appearance (OA), inside appearance (IA), and flavor & texture (FT) of 38 breads using 46 items of sensory evaluation. Findings are as follows: for the OA, $X_1$ (P<0.05) and $X_4$ (P<0.0001) exhibited significant individual effects, whereas $X_1*X_7$, $X_2*X_5$, $X_3*X_6$, and $X_4*X_6$ indicated significant interaction effects (P<0.05). For the IA, $X_1$ (P<0.0001), $X_4$ (P<0.0001), $X_6$ (P<0.05), $X_2*X_4$ (P<0.05), and $X_3*X_6$ (P<0.01) showed individual and interaction effects, respectively. For the FT, $X_1$ and $X_2$ showed the most significant individual effect (P<0.0001), followed by $X_4$, $X_5$ and $X_6$ (P<0.05) in descending order. $X_4*X_7$ indicated the only significant interaction effect. We computed the magnitudes of the 2-way interaction effects of the ingredients with a distinct emphasis. Model equations predicting the levels of the ingredient effects on the breads were also provided via regression analyses. In summation, $X_4$ appeared to be the most significant component affecting the sensory characteristics based on its individual and 2-way interaction effects. Further, $X_6$, $X_1$, $X_2$, and $X_5$ indicated both individual and interaction effects. $X_3$ and X7 showed only interaction effects. The center point effect appeared to be unequivocal for whole sensory characteristics. Findings of the present study may provide insights into the selection of ingredients to derive an optimal model for turmeric powder-added bread using the response surface method hereafter.

  • We investigated the quality characteristics of dohwaju (fermented with peach flowers and branches, a Korean traditional alcoholic beverage) containing different sub-ingredients. During fermentation, the inner temperatures of the added sub-ingredient treatments were higher compared to non-treatment, and only peach branches treatment. showed the highest inner temperature. There were no significant differences in the physicochemical results among the treatments. pH decreased from the first mashing day to the second and then increased slightly until fermentation was terminated. Total acidities showed opposite patterns as compared to pH level. Amino acid contents, soluble solids, and alcohol contents increased steadily until the end of fermentation, whereas reducing sugar contents showed the opposite trend. In a preference survey, DB (only peach branches)-treated dowhaju showed the highest evaluation in terms of taste and overall acceptability with walues of $5.07{\pm}1.38$ and $5.57{\pm}1.16$, respectively. Based on the results of this study, we concluded that only peach branches treatment is optimal for the manufacture of dowhaju. We expect that the quality of dowhaju can be improved by providing basic information concerning its manufacture.

  • Recently, the health-promoting effects of functional foods have been shown to prevent nutrition-related diseases, improve physical and mental well-being, satisfy hunger, and provide necessary nutrients for the human body. Koumiss is a common type of fermented mare's milk that has been shown to have beneficial therapeutic effects on cardiovascular disease, tuberculosis, and diarrhea as it can nourish vessels, relieve ill mood, and improve digestion. Hence, in this study, we aimed to prepare health-promoting koumiss using different concentrations of flaxseed (Linum usitatissimmum L.), which has the potential to control heart disease, hypertension, inflammation, and lung function. The pH was decreased to around 4.42-4.43, whereas the total anthocyanin (TA) content was increased to around 0.78~0.82% after fermentation of the koumiss premix. There were no significant differences in pH and TA among the three groups, including the control group. In sensory profile analysis, the taste, flavor, color, texture, and overall acceptability decreased in proportion to the added amount of flaxseed. These findings provided the first data describing the effects of flaxseed on koumiss fermentation, establishing a basis for commercial-scale production of koumiss containing fermented flax seed and for improving the health-promoting activity of koumiss.

  • This study was conducted to investigate the preference for and recognition of Makgeolli by foreign students to determine its potential for export. From March 15 to 29, 2010, 300 students from four universities (Kyung-Hee University, Hankuk University of Foreign Studies, Yonsei University, Chung-Ang University) were surveyed and data from 287 subjects were used for subsequent analyses. The recognition of Makgeolli was as follows: 40.3% knew that Makgeolli's was fermented alcohol; 49.5% knew its proof; 85.7% knew that rice and wheat were the main ingredients of Makgeolli; 72.8% knew it was Korean traditional alcohol. The preference for Makgeolli's was as follows: flavor (3.46), color (3.43), aroma (3.30), texture (3.28), reverberation (3.36), shape of glass (3.51) and Korean bar (3.72), which were slightly high. However, hangover (3.02) and plastic bottle (3.08) had lower values than the other variables. Overall, participants were likely to recommend Makgeolli to others (Male 3.57, Female 3.72), but they did not think that it is a good ingredient for food (2.91). The opportunity for the globalization of Makgeolli appeared to be high (Male 3.57, Female 3.74). To improve the export of Makgoelli, respondents reported that a better marketing strategy (37%) and new type of bottle (42.8%) were needed.

  • In this study, the quality characteristics and antioxidant activities of wet noodles added with doraji (Platycodon grandiflourm) powder at concentrations of 1%, 2%, 3%, and 4%, respectively, were investigated. The crude protein, crude fat, crude ash, crude fiber, and moisture contents of the dried doraji powder were 11.00%, 0.95%, 4.10%, 29.64%, and 6.21%, respectively. As the added amount of doraji powder increased, weight, volume, and water absorption of the wet noodles after cooking decreased. However, the turbidity of the soup increased. Color L values of wet and cooked noodles decreased, while a and b values increased by the addition of doraji powder. Texture measurement indicated that hardness, cohesiveness, springiness, and chewiness of the cooked noodles decreased by addition of doraji powder. The total polyphenol contents and DPPH radical scavenging activity in wet noodles added with doraji powder increased with increasing amounts of doraji powder. Finally, sensory evaluation of wet noodles added with doraji powder revealed that taste significantly decreased. However, flavor, color, texture, appearance, and overall acceptance scores for the 1% addition group ranked significantly higher than those of the other groups. In conclusion, these findings suggest that doraji powder could be used as functional food ingredients.

  • This study was conducted to develop a topping formula for pizza containing Chungkukjang and onion as the main ingredients. The maximum amount of onion was limited to 10.5%, since the pizza crust and toppings would separate if too much water dispelled from the onion tissue during baking. The Chungkukjang was substituted for Bulgoggi, a meat topping. The sensory acceptability scores for the pizza topping decreased as the amount of Chungkukjang increased from 3.6% to 7.3%, due to its unpleasant odor, but scores increased when 1.6% Kimchi powder was added to the Chungkukjang without a significant difference from the control. Thus favorable sensory quality was obtained with a topping formula containing 8.7% Chungkukjang, 10.5% onion, and 1.6% Kimchi powder. The nutrient values of the final pizza products were assessed as follows. By adding the Chungkukjang and onion, crude protein, crude lipid, crude ash, and total dietary fiber contents increased. Moreover, the calorie level of the Chungkukjang-onion pizza was 3.8% higher than that of the control pizza. The amounts of compound amino acids including lysine increased. The free amino acids also increased from 143.3 to 188.6 mg/100 g. The ratio of saturated fatty acids to unsaturated fatty acids changed from 1:0.71 to 1:0.81. For the consumer test, the age groups of the participants were classified as 15-29 years old, 30-39 years old, and 40-62 years old. A positive result on acceptability of the developed pizza was obtained from most of the panelists in all age groups. Over 93% of the 119 responding subjects had purchasing intentions. An, especially, strong purchaging intention was shown in the younger age group of 15-29 year-olds, even though they had a lower preference for the Chungkukjang. Finally, an attribute of satisfaction was induced based on 'health' (79.5%) and 'flavor' (15.7%).
