  • This study was conducted to evaluate the antibacterial activity against Cronobacter sakazakii and Salmonella enteritidis as well as the sensory attributes of milk products supplemented with various concentrations (control, 0.5%, 1.0%, 1.5%, and 2.0%) of clove oil. In this study, clove oil was shown to have strong antibacterial activities. In addition, all the samples were assessed by ten researchers trained in five sensory attributes, namely, taste, flavor, color, texture, and overall acceptability. Compared to the control, 5% clove oil supplemented was the best in market milk, while in yogurt and kefir, 1.0% supplementation was the best. In terms of sensory attributes, the low score of color and flavor of market milk, yogurt, and kefir is attributed to the characteristics of the supplemented clove oil. Consequently, this study presents the possibility of producing bio-functional milk products supplemented with clove oil, and for controlling the growth of foodborne pathogenic bacteria in milk products using clove oil.

  • This study evaluated the degree of harmony of food pairing with Korean traditional liquors according to the taste and flavor. In-depth interviews were performed with eight experts from May 7 to 17, 2016, to screen Korean traditional liquor and food. For traditional liquor, Sanseong-makgeolli, Hansansogokju, Damsol, Gamhongro, and Andong Soju were chosen. For foods, pan-fried beef, squid with vinegar dressing, clam soup, honey-filled rice cake, prune, grilled mushroom, Swiss cheese, pistachio, honey, and chocolate cake were chosen. Harmonization of the analytical results Sanseong-makgeolli, between honey and Pan-fried Beef achieved the most harmonious results. Hansansogokju with honey and prune were harmonious. Damsol and Gamhongro, which are distilled liquor and containing added ingredients, were perfect matched with chocolate cake and squid with vinegar dressing. In the degree of harmony between Andong Soju and food, it was confirmed that squid vinegar and Swiss cheese were the most harmonious. Through the results of this study, it was found that the degree of harmony with food was different depending on the characteristics of alcoholic beverages. In addition, it is believed that not only taste and flavor, but also the alcohol content of alcoholic beverages will play an important role in the harmony with food.

  • 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.

  • The purpose of this study was to investigate the quality characteristics of cookies containing Ligularia fischeri powder (0, 1, 2, 3, 4%) substituted for flour. This study measured the density, pH, spread ratio, volume, color values, hardness, and sensory properties of cookies. The pH of cookie dough significantly decreased in response to addition of Ligularia fischeri powder (LFP) at all levels. The spread factor of cookies also significantly increased with higher LFP content. In addition, Hunter's color L, a, and b values significantly decreased with increasing LFP content. According to hardness measurement, substitution of 1~4% LFP resulted in increased hardness compared to the control. In the sensory evaluation, sensory scores for color, flavor, and overall acceptability were highest in 2% Ligularia fischeri powder cookies. Thus, our results suggest that the optimum amount of Ligularia fischeri powder added to cookies was 2%. These results suggest that Ligularia fischeri powder can be applied to cookies to achieve high quality and functionality.

  • The present study was conducted to investigate quality characteristics of Nochi made with malted barley flour with (Cl) and without hull (C2), comparing with Nochi that was treated with different sources of commercial amylases. There was higher level of moisture content (18.4%) in Nochi treated with fungal ${\alpha}$-amylase (FU) comparing with the other Nochi samples. However, Nochi that was treated with bacterial ${\alpha}$-amylase and ${\beta}$-amylase (BA-${\beta}$) had the lowest level of moisture content (11.2%). Nochi samples which were treated with thermostable ${\alpha}$-amylase and fungal ${\alpha}$-amylase(TE-FU) were different from traditional Nochi samples in mechanical characteristics. According to the results of sensory evaluation, Cl was similar to C2 except in cohesiveness and malt flavor. TE-FU and Bh-${\beta}$ were not different from traditional Nochi in cohesiveness, sweetness and overall desirability.

  • This study was performed to examine the optimum addition amount of Hizikia fusiformis powder to be used with rice flour in the preparation of Hizikia fusiformis Sulgidduk (traditional rice cake). Hizikia fusiformis powder was added to rice powder at ratios of 5, 10, 15 and 20% (w/w). The moisture content of Sulgidduk was increased with the addition of Hizikia fusiformis powder, whereas the pH content was decreased. The addition also lowered the lightness and yellowness values but increased the greenness value. Mineral contents were increased. Hardness, springiness, and brittleness were decreased, and cohesiveness was increased as the added powder content also increased. In the sensory evaluation of Hizikia fusiformis Sulgidduk, color, flavor, taste, softness, chewiness, moistness, cohesiveness, and overall acceptability characteristics were all highest at the 10% addition level. Thus it can be proposed that this is the ideal level of Hizikia fusiformis addition in terms of the sensory properties of the cooked product.
