  • The objective of this study was to evaluate the quality characteristics of lotus root Dasik prepared by different additions of lotus root powder (0%, 20%, 40%, 60%, 80%). As the level of lotus root powder in the formulation increased, the moisture contents of samples increased. Also, the L-, a-, and b-values of samples significantly decreased as the amount of lotus root powder increased. According to the results for mechanical characteristics, hardness, gumminess, springiness, cohesiveness, and chewiness decreased, whereas adhesiveness increased, as the amount of lotus root powder increased. The sensory evaluation results showed that the 40% lotus root sample received the highest preference scores; therefore, the 40% lotus root Dasik prepared with 60 g of flour, 40 g of lotus root powder, and 80 g of honey was chosen as the superior product.

  • Color, an important visual cue, can cross-modally affect odor association and odor quality identification Here, this research investigates aspects of the cross-modal associations between color and fragrance in greater depth, delving into the topic of whether the degree-of-association of fragrances with hue and tone of colors varies systematically. For 33 color stimuli (10 hues, 3 tones, and 3 achromatic colors), 67 subjects judged the degree-of-association of four typical fragrance families (fresh, floral, oriental, and woody) on a 7-point scale. The statistical analysis showed that fragrance associations of the all families had characteristic distributions across ten hues of the color stimuli. The cross-modal relationship between color tone (especially, lightness attribute) and fragrance association appeared to be dimensional (e.g. a positive linear relationship between the floral family and the lightness). More specifically, as colors became warmer and brighter, the associated floral scents were stronger, while the woody scents was less associated. Brighter or more vivid cool colors were associated with stronger fresh scents. These findings confirm the systematic existence of synthetic interactions between vision and olfaction in perfumery.

  • If an association for a color develops and comes to form any kind of common idea, a symbolic meaning is given to the color. It is called' symbolism of color' that color builds up an abstract general idea, an emblem, feeling except things concrete. The color of game is the visual element that one can be immersed in the game, the image which act as important meaning, the attribute of light, and visual perceptional factor. With form, motion, light and shade, the color function importantly as media which express a person and person's circumstance. In game, the color is used symbolically to suggest not only mental change of character but also the situation, mood, attribute and strength of energy. These transmission of meaning express symbolism of the color iconically. So, the color for image express of game take on universality. This study research that focus on how the symbolical meaning of the color is reflected in game.

  • Epoxy polymer exposed to solar radiation on long-term is required to a long-term environmental test in order to ensure the reliability of operation performance. In this paper, the solar aging experiment is performed for 7, 14, 28, 56, and 84 cycles, using solar simulator designed according to MIL-STD-810. After the aging experiment, measuring RGB values and using the CIE1976 color space, each RGB decreasing rates and total color shift are calculated. In addition, using a universal testing machine, mechnical properties according to ASTM-D638 are measured. As a result, by increasing solar aging period, total color shift is increased, and the tensile strength and elongation are decreased, but the elastic modulus and the poisson's ratio are slightly changed.

  • To optimize the preparation process of Jeung-Pyun, an experiment was derived, using a central composite design, to fmd the optimal mixing conditions. The addition of Paecilomyces japonica powder, the volume of Tak-Ju and the second fermentation time were independent variables, with the pH, volume, color, sensory and texture properties of the Jeung-Pyun selected as response variables. As the Paecilomyces japonica powder and fermentation time were increased, the b values and volume after the second fermentation also increased. The color of the Jeung-Pyun became deeper with increases in the Paecilomyces japonica powder and fermentation time, and was deepest on the addition of 30% Tak-Ju. The pH increased with increasing fermentation time of the Jeung-Pyun, and on the addition of 3% Paecilomyces japonica rapidly increased more than with the other groups. The optimal mixing conditions for the best quality Jeung-Pyun, with restricted conditions above a b value of 3, a color intensity above 3, and a volume of 40mQ and a pH of 4.02-4.04 after the second fermentation, were 4.0%, 20% and 45 mins for the Paecilomyces japonica powder, Tak-Ju and second fermentation time, respectively.

  • Qualitative properties- polyphenol compounds(total phenolics, anthocyanin, flavonoids, tannins), color parameters and antioxidant activities- of wild grape wine having different aging periods were studied. The contents of total phenolics and anthocyanin decreased significantly in accordance with aging terms(p<0.05). The total phenolics and anthocyanin of the oldest wine(WG3) represented only 43% and 45% of it's related compound in the wine aged for one year(WG1), respectively. The contents and the degree of polymerization of tannins, including condensed tannins, also decreased but not showed statistically significant. However, The contents of flavonoids of the 2 year old wine(WG2) decreased significantly related to that of WG1, remaining, then, almost constant at that levels during aging. The L* values, b(yellow) values and the hue (hab) values were increased in long aged wines(WG2, WG3), while the intensity of color(CI) and, the a(red) parameter value decreased. The antiradical activity of wild grape wines was shown to be high(87 EDA%) in WG1. The corresponding coefficient of tannin concentrations with antiradical activity($r^2$=0.9189) suggests that the tannin content may be strongly related to the antioxidant properties of wild grape wines.

  • This study was intended to develop a value-added and functional sauce with addition of Chungkukjang powder. This study was conducted as the following procedure. 10%, 20%, 30%, and 40% of Chungkukjang powder was respectively added to make different Bechamel sauces. And then, physical testing (moisture, color value, viscosity, salinity, spreadability and pH) and sensory testing (a quantitative descriptive analysis and an acceptance test) were performed. After that, the correlation between the physical testing and the sensory testing was investigated to choose an optimal mixture ratio. The study results are presented as follows. As the addition percentage of Chungkukjang powder increased, a-value, b-value, salinity, spreadability, and pH significantly increased (p<0.001), but moisture content, L-value and viscosity decreased. The QDA result indicated that, regarding color intensity(5.89), Chungkukjang flavor(5.32) and Chungkukjang taste(6.26), the 40% addition group had the highest value, and that, regarding thickness(6.42), milk flavor(5.00), oily taste(5.21), mouth feel(5.32), the control group had the highest value. As a result, as the addition percentage of Chungkukjang powder increased, color intensity, Chungkukjang flavor, and Chungkukjang taste increased, but thickness, milk flavor, oily taste, and mouth feel decreased. According to the result of acceptance test, the 20% addition group had the highest value in terms of appearance, flavor, taste, glossy and overall acceptance. As shown earlier, it is considered that proper addition of Chungkukjang powder positively affects the overall acceptance, and that the 20% addition of Chungkukjang powder is most suitable to improve the sensory and physical quality-characteristics of Bechamel sauce.

  • In this study, the quality characteristics of Topokkidduk, a traditional Korean rice cake, containing different amounts of garlic powder (0, 1, 3, 5, 7 w/w %) were investigated. The moisture content of Topokkidduk containing garlic ranged from 45.72~46.74% and was significantly higher than Topokkidduk in the absence of garlic. The Hunter color L value decreased with an increase in the amount of added garlic powder, whereas the a and b values increased. Texture analysis revealed that the hardness of uncooked Topokkidduk was significantly lower than Topokkidduk not containing garlic (p>0.05). The adhesiveness and springiness of both uncooked and cooked Topokkidduk did not vary significantly at the different garlic concentrations (p>0.05). The chewiness of Topokkidduk tended to decrease with an increase in the amount of added garlic powder. For the sensory evaluation, the intensity (color and flavor) and acceptability (color, flavor and taste) were lower for Topokkidduk containing 7% garlic powder than the other samples. The chewiness intensity was highest for Topokkidduk containing 1% and 3% garlic powder (p>0.05). The Topokkidduk containing no garlic powder and 3% garlic powder had the highest overall acceptability score (p>0.05).

  • The present study investigated the relationship between physical conditions and sensory properties of red pepper powder stored at different temperatures ($-20^{\circ}C$, $0^{\circ}C$, $20^{\circ}C$) and in different wrap materials (linear low density polyethylene, LLDPE; aluminum/linear low density polyethylene, Al/LLDPE). Red pepper powders with initial moisture contents of $17.35{\pm}0.32$% were not affected by the packaging material or storage temperature. Hunter a values of red pepper powder decreased while Hunter b values increased as storage temperature increased. There were no significant differences according to packaging materials. The American Spice Trade Association (ASTA) color value ($60.85{\pm}0.13$) significantly decreased with increasing temperature from $-20^{\circ}C$ to $20^{\circ}C$ ($21.70{\pm}0.06$ to $56.03{\pm}0.24$). The ASTA color value of samples packed with LLDPE ($21.70{\pm}0.06$) decreased more compared to samples packed with other materials. Further, capsanthin contents ($13.74{\pm}0.02$ mg/100 g) significantly decreased with increasing temperature from $-20^{\circ}C$ ($0.25{\pm}0.01$ to $0.28{\pm}0.01$ mg/100 g) to $20^{\circ}C$ ($0.13{\pm}0.01$ to $0.25{\pm}0.01$ mg/100 g). In the sensory evaluation of red pepper powder, overall acceptability was influenced by redness, yellowness, and pungency color. All physicochemical and sensory properties of red pepper powder were compared. Hunter a values, ASTA color values, and capsanthin contents were significantly associated with sensory preferences. In particular, ASTA color value showed a close relationship with color preference for red pepper (R2=0.922). Thus, we suggest that the preference for red pepper powder can be determined based on instrumental measurements of Hunter a values, ASTA color values, and capsanthin contents.

  • The fermentation characteristics of ice wines made from freeze-dried Muscat Bailey A grapes were determined. Muscat Bailey A grapes were concentrated to 34.8 and $40.8^{\circ}Bx$ by freeze drying and were then fermented. The content of reducing sugar was 0.3% in conventional wine after fermentation, but was 21.5 and 23.9% in ice wines at 34 and $40^{\circ}Bx$, respectively. The content of alcohol was 9.6% in conventional wine but was 10.3 and 10.6% in ice wines at 34 and $40^{\circ}Bx$, respectively. It was observed that the red and violet colors of ice wines at 34 and $40^{\circ}Bx$ became dominant compared to the controls. In sensory evaluation studies, ice wines at 34 and $40^{\circ}Bx$ showed higher intensities in color, flavor, and overall preference.
