  • When consumer evaluates a product, every aspec of the product affects the evaluation. Human uses at least five sensory organs for the evaluation. Multi-sensory or multi-modal design tries to add auditory and olfactory factors to the traditional visual-centered design. For the multi-modal design, it is essential to understand relationships between combined sensory stimuli and human sensibility. Information between simple sensory stimulus and human sensibility is pre-requisite to combine multi-modal stimuli. This study investigated human sensibility against 8 colors and 30 sounds, presented independently. The combined stimuli of color and sound were made based on the sensibility generated by each stimulus. Human sensibility generated by the combined stimuli of color and sound were made based on the sensibility generated by each stimulus. Human sensibility generated by the combined stimuli was investigated with 20 female subjects. For combined stimuli that generated the same kind of sensibility respectively, generated sensibility was same but strength was diminished. For combined stimuli that generated the different sensibilities respectively, subjects showed neutral sensibility or no special sensibilities. Sensibilities to the same stimuli also showed difference depending on personal background of the subjects.

  • This study was done to develop the standard recipe for nutritious cowpea starch based grape jelly. The effects of grape juice concentration (4, 8, 12%) and 0.2% calcium addition were evaluated on textural and sensory properties of grape jelly through the instrumental analysis using rheometer and sensory evaluation. Instrumental analysis showed that hardness, chewiness and gumminess of grape jelly was incerased significantly In jelly made of higher concentration of grape juice, and also in 0.2% calcium containing jelly. According to sensory evaluation, higher grape juice contains jelly showed advantages in preference of color and overall quality. Calcium addition increased sourness in sensory score. Overall, 12% grape juice and 0.2% calcium containing jelly was most preferable, which means calcium fortified cowpea starch based grape jelly was successful try for nutritious and practical food for elementary school foodservice.

  • This study attempted to examine the effects on sensory characteristics, texture and color of steamed soybean rice cake in various levels of soybeans. Sensory evaluation was done by panels of 7 judges. Objective measurements were made by utilizing the Instron and Hunter Colormeter. The results were as follows; 1. The content of moisture, total ash, protein, fat and carbohydrate in rice were shown to be about 13.47%, 0.48%, 6.40%, 0.54% and 79.11%. Those of soybean were 10.95%, 4.54%, 30.67%, 20.36% and 33.48%. 2. The results of sensory evaluation revealed that rice cake containg 20% of soybean produced the best quality in most sensory characteristics. 3. By Instron measurement of various levels of soybean in steamed soybean rice cake, hardness and cohesiveness were not different. By color value of that, b value was tend to increase as the addition level of soybean.

  • This study was conducted to investigate the effect of Korean red pepper extracts on physiological and sensory characteristics. The Korean red pepper extracts were added to chocolate at weight percentages of 0, 2, 4, and 6%. The sensory characteristics made with various Korean red pepper concentrations of the additives were measured as follows: color values (L-value, redness, and yellowness), total phenol, total capsaicinoid, total carotenoid, and ABTS radical scavenging activity. In sensory evaluation, significant differences (p<0.05 and p<0.01) were shown in taste, spiciness, and overall acceptability depending on the addition of pepper extracts. However, there were no significant differences in the properties of aroma and bitterness for chocolate.

  • Kochujang was prepared by using retrograded rice cakes (Song Pyun, Sym rice cake, Ssuk rice cake, Pat rice cake) as a source starch and the physiochemical and sensory characteristics were compared with traditional kochujang during aging for 60 days. Moisture content of all kochujang groups increased slowly but crude fat content decreased according to aging process. Changes of pH values of all kochujang reduced gradually during aging and the pH of saccharified kochujang was lowered than that of traditional one. Total reducing sugar contents in saccharified kochujang reached the maximum value at 50th day, and decreased thereafter. In contrast, the reducing sugar content in traditional kochujang was the highest at 30-day-aging. After 60 days of aging, the total contents of organic acids were 28.57 mg for P$\_$1/, 27.9 mg for P$\_$4/, 27.05 mg for P$\_$3/ 24.60 mg for P$\_$2/, and 22.30 mg for P$\_$0/. By sensory evaluation, saccharified kochujang prepared with Siru rice cake showed the highest sensory score in its appearance, flavor, texture, color, and taste.

  • Yackwa was prepared by the addition of different amounts of egg white, and the samples were analyzed by texture profile analysis, Hunter's colorimetry and sensory evaluation during 5 days of storage. Tn texture profile analysis, the hardness, gumminess and chewiness of Yackwa were increased in all the samples during storage and the texture parameters were increased by increasing egg white level. No significant difference was observed in the lightness, redness and yellowness (p〉0.05), but Hunter's color values were slightly increased during storage in all the samples. In sensory evaluation, no significant difference was observed among the samples during storage except the increase of crispiness and overall acceptance by the addition of egg white. The results showed that Yackwa prepared with 10 g of egg white/(100 g of other ingredients ---약과재료 얼마당 10g 첨가인지 명확히 해야 함) had an acceptable sensory quality.

  • The purpose of this study was to investigate quality characteristics of Seolgidduk containing 0, 3, 5, 7 and 9% Poria cocos Wolf powder during the storage at 2$0^{\circ}C$ by measuring water content, color value, texture and sensory characteristics. By increasing the amount of Poria cocos Wolf powder, water content of Seolgidduk did not show any significant difference during storage. Hunter color L value of Seolgidduk decreased, and a and b value increased significantly by increasing the amount of Poria cocos Wolf powder. The cohesiveness of Seolgidduk decreased but adhesiveness, gumminess and chewiness were not significantly different by increasing the amount of Poria cocos Wolf powder. 3% Poria cocos Wolf added Seolgidduk was the highest in color, odor, taste, softness, moistness and overall preference from the sensory evaluation. Above results indicated that 3% Poria cocos Wolf added Seolgidduk showed the best quality through sensory and texture analysis.

  • The saccharification and sensory characteristics of Sikhe, Korean traditional beverage of saccharified rice, made from thirteen glutinous rice varieties and one of non-glutinous rice named I1pum were examined. During saccharification, Shinsunchalbyeo, Whasunchalbyeo, Yukdononhrimna 1 and Hangangchalbyeo showed the highest sweetness determined by refractometer. Yukdononhrimna 1 was good for the morphology and texture of cooked rice kernel during saccharification. There was interrelationship between contents of released reducing sugar and sweetness determined by refractometer during preparation of Sikhe. The overall acceptability determined by sensory evaluation of Sikhe made from Yukdonongrimna 1, was slightly higher than that of Sikhe made from Ilpum, the non-glutionous rice variety. Yukdononhrimna 1 was considered to the most suitable varieties of Sikhe.

  • The purpose of this study was to investigate the sensory and mechanical characteristics of Mohaebyung by the addition of chestnut, jujube, dried persimmon, pine nut, and codonopsis lanceolata flours. In the sensory evaluation of Mohaebyung, the acceptance for the color, moistness and sweetness was best with the addition of 25% mixed flour. The flavor, grain, chewiness and overall quality were best with the addition of 20% mixed flour. As a result of a textural analysis, the hardness and springiness of Mohaebyung decreased with increases in the addition of mixed flour. The redness, yellowness and lightness of Mohaebyung were increased with increases in the addition of mixed flour. A moisture content of 15% in the mixed flour added to the Mohaebyung was higher with 25% mixed flour.
