  • The feasibility of incorporating jujube powder as a value-added food ingredient in cookies was investigated. The amount of jujube powder added (0~20%) was found to have significantly affected the cookie quality (p<0.05). Furthermore, the pH ranged from 6.16 to 6.69, and moisture content gradually increased from 4.11% to 4.76%, while the spread ratio and loss rate have significantly decreased with the increasing levels of the powder added (p<0.05). Lightness decreased; however, the redness and yellowness, as well as hardness, have significantly increased with the higher amount of jujube powder in the formulation (p<0.05). In addition, 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical scavenging activity was significantly increased (p<0.05) without remarkable differences between the control and 5% sample, and 15% and 20% sample (p>0.05). The consumer acceptance test indicated that the addition of jujube powder of up to 10% had a favorable effect on the consumer preferences in general. Based on the overall observation, the cookies with 5~10% jujube powder is recommended for taking advantage of the functional properties of jujube powder without sacrificing the sensory quality.

  • Nutritional compositions, volatile compounds, and sensory attributes of grilled and fast-chilled mackerel (Scomber japonicus) were analyzed in order to examine its practical utilization as a food resource compared to commercial frozen mackerel. In the proximate analysis, lipid contents were $27.3{\pm}2.7%$ in grilled and fast-chilled mackerel. Palmitic acid was the most predominant fatty acid (20.68% and 18.88%), and the percentages of polyunsaturated fatty acid were higher than 40% in both. No benzopyrene was found in the grilled mackerel, and even grilling was employed at $260^{\circ}C$. For chemical stabilities, para-anisidine value (8.56 vs. 9.26) and acid value (2.96 vs. 3.35) in grilled mackerel were improved compared to those of commercial mackerel. Moreover, color index of grilled mackerel, a physiological property, showed greater lightness than commercial mackerel. Lastly, analysis of volatile compounds by gas chromatographic analysis and sensory tests by trained panels demonstrated higher potential for grilled mackerel as a highly marketable product compared to commercial mackerel. Taken altogether, the above results provide important preliminary results for utilization of grilled and fast-chilled mackerel as a quality food.

  • Visual perception information acquired through human eyes contains much information on how to view visual stimuli using eye tracking technology, it is possible to acquire and analyze consumer visual information as quantitative data. These measurements can be used to measure emotions that customers feel unconsciously, and they can be directly collected by numerically quantifying the character's search response through eye tracking. In this study, we traced the character's area of interest (AOI) and found that the average of fixation duration, count, average of visit duration, count, and finally the time to first fixation was analyzed. As a result of analysis, it was found that there were many cognitive processing processes on the face than the character's body, and the visual attention was high. The visual attention of attraction factor has also been able to verify that attraction is being presented as an important factor in determining preferences for characters. Based on the results of this study, further studies of more characters will be conducted and quantitative interpretation methods can be used as basic data for character development and factors to be considered in determining character design.
