This study was conducted to analyze sensory characteristics and consumer acceptance with cookies made using various levels(0, 2, 4, 6 and 8% w/w) of Chrysanthemum indicum L. powder. Ten panels assessed sensory characteristics using a 15-point hedonic scale and forty-five consumers evaluated their acceptance based on a 7-point hedonic scale and best-worst scaling. The descriptive analyses reveled that cookie flavor did not differ significantly between the 2% added sample and the control. Cookie color and after taste increased significantly, while hardness, roasted taste, and sweetness taste decreased significantly according to increasing Chrysanthemum indicum L. powder concentration. In addition, the results of consumer acceptance showed that the overall acceptability, appearance, color, flavor, and taste decreased significantly in response to increasing Chrysanthemum indicum L. powder concentration. However, color, flavor, taste and overall acceptance with cookies did not differ significantly differ between the 2% and 4% sample. Additionally, among the cookies made with Chrysanthemum indicum L. powder, the 2% sample received the highest scores. In conclusion, the sensory optimal ratio of Chrysanthemum indicum L. powder was 2% based on the descriptive analysis of sensory characteristics and the consumer-acceptance testing.

In this study, the quality characteristics of noodles containing different amounts of germinated black quinoa were investigated. The powder of black quinoa with the highest antioxidative activation was selected; and composite flour was prepared with 0%, 5%, 10%, 15%, and 20% of germinated black quinoa powder to produce the noodles. We evaluated the quality and sensory characteristics of the noodles, including pH, salinity, water absorption rate, volumetric expansion rate, turbidity, chromaticity, extensibility, and texture. With regards to the quality characteristics of noodles with added germinated black quinoa, the pH and salinity decreased with increasing percentage of added germinated black quinoa (p<0.001). Increasing the percentage of added germinated black quinoa resulted in decreased water absorption (p<0.01) and volumetric expansion rates and increased turbidity of the cooked noodles (p<0.001). In terms of the chromaticity, L and b values decreased and a value increased with the increasing percentage of added germinated black quinoa (p<0.001). For the texture, hardness (p<0.001), adhesiveness (p<0.01), springiness (p<0.01), chewiness (p<0.001), gumminess (p<0.001), and cohesiveness (p<0.05) decreased as the percentage of added germinated black quinoa increased; while extensibility (p<0.001) increased. Consumer testing results indicated that the noodles with 15% of added germinated black quinoa showed the best results. Collectively, the evaluation of quality characteristics and consumer acceptability indicated that adding 15% of germinated black quinoa to produce noodles is optimal.

This study was conducted to identify sensory characteristics of soy-meat samples by trained panels and to observe the relationship between these sensory characteristics and consumer acceptability of the samples. Descriptive analysis was performed on eight samples; four types of patty style soy-meat samples (Soy-meat Patty; SP) made with a Ddukgalbi recipe (YSP, VSP, LSP, and SSP) and four types of Bulgogi style soy-meat samples (Soy-meat Bulgogi; SB) made with a Bulgogi recipe (YSB, VSB, LSB, and SSB). Seven panelists were trained, and they evaluated the appearance, odor/aroma, flavor/taste, texture/mouth feel, and after taste attributes of these samples. Forty attributes were generated by panelists, and 37 attributes were significantly different across products (p<0.05). The SB group was characterized by beef, leek, and garlic flavor as well a sweetness, denseness, slipperiness, chewiness, and pepper after taste. The SP group was characterized by roughness, particle size, rancid oil flavor, raw bean flavor, astringent, sourness, and adhesiveness. Consumer test (n=125) showed that the VSB sample had the highest scores for acceptability of appearance, flavor, texture, and overall liking. The PLSR results show that the attributes that were more positively associated with acceptance of soy-meat samples were beef taste, wetness, and chewiness, whereas the raw bean smell and rancid oil flavor attributes were negative.

Purpose: This study was conducted to investigate the effect of cabbage powder on the quality characteristics of rice nutritional bars. Methods: In order to analyze quality characteristics, total phenolic content, DPPH free radical scavenging activity, baking loss rate, leavening rate, specific volume, moisture content, color, texture analysis, and sensory evaluations were assessed. Results: The total phenolic content and DPPH free radical scavenging activity of rice nutritional bars significantly increased with an increase in the content of cabbage powder (p<0.05). The baking loss rate, leavening rate, specific volume, and moisture content of the rice nutritional bars were significantly reduced as the amount of added cabbage powder increased (p<0.05). As the concentration of cabbage powder increased, the lightness and redness of the bars' crust and crumbs decreased, while yellowness increased (p<0.05). In texture analysis, the control bars showed the highest hardness values. Adhesiveness, springiness, and cohesiveness values slightly decreased with higher cabbage powder content in the groups with added cabbage powder (p<0.05). When consumer acceptability was measured, rice nutritional bars prepared with 15% cabbage powder showed the highest scores in color, whereas the rice nutritional bars prepared with 20% cabbage powder showed the lowest scores in flavor (p<0.05). In characteristic intensity rating, the taste and off-flavor of rice nutritional bars significantly increased with increasing amounts of cabbage powder (p<0.05). Conclusion: Judging from our results, it can be concluded that the addition of cabbage powder to rice nutritional bars during processing can enhance consumer preference for the bars, total phenolic content, and DPPH free radical scavenging activity.

This study investigates how visual appearance of pork cuts affects consumer preference. Images of pork belly, Boston butt, and loin were chosen on the basis of visible fattiness and used to analyze consumers' perception of the appearance of each pork cut. Meat color and visible fat proportion of images of pork cuts were analyzed by the researchers before conducting the survey. A total of 211 pork eaters evaluated the pork cuts based on appearance (lightness of color, redness, visible fat proportion, and fat distribution), preferability, and overall acceptability. Also, muscle pieces from different pork cuts were taken and the relative area composition of muscle fibers was measured. Based on survey results, correlation between visual traits and preferences of each pork cut was analyzed. The survey results showed that preferred pork appearance varied as per each individual's favorite pork cut. Also, the respondents evaluated visual characteristics and preference for each pork cut differently possibly due to the different visual characteristics of each cut. Correlation analysis between visual traits and preference indicated that overall acceptability of pork cuts was mainly influenced by fat preference, followed by color preference. Fat and color preferences for each pork cut were affected by various visual attributes including redness, lightness of color, visible fat proportion, and fat distribution, but their effects were considerably varied among different pork cuts. Thus, Korean consumers perceived and assessed pork appearance using various quality cues but the evaluation depended on which cut was being observed.

This study compares the net effect of wearing different shoulder/arm armor systems on garment impediment perception and wearer acceptability. Two independent variables in this study were armor systems and shoulder/ arm movements. There were four armor systems of control garment and arm armor systems A, B, and C as well as five types of arm/shoulder movements, (shoulder flexion, should extension, shoulder abduction, shoulder horizontal flexion, and shoulder horizontal extension). Ten male volunteers wearing size medium battle dress uniform (BDU) with recent relevant military experience participated in this study. The volunteers performed shoulder/arm movements (while wearing each armor treatments) and completed the garment impediment perception as well as wearer acceptability scales. The body areas of neck side, shoulder top, and armscye front showed the highest frequency of reported impediments. Resistance to movement and localized pressure were the most frequently mentioned types of impediment. The armor system B had the most areas of impediment, and was rated as more restrictive than the control garment and armor system A for each movement. For wearer acceptability, no significant differences were found between the control garment and armor system A for all eight items; this indicated that subjects did not perceive a difference between wearing the control garment and armor system A. There was a trend for wearer acceptability to decrease from wearing the control garment to armor systems A to C to B.

Sujeonggwa is a popular Korean traditional beverage. However, consumers only prepare it at home on special occasions due to the time and effort required. Developing a convenient form of Sujeonggwa may promote its consumption. The objectives of this study were to 1) develop Sujeonggwa in a tea bag using different sweeteners and 2) describe the characteristics of Sujeonggwa's flavor in tea bag samples and 3) determine how well consumers accept the tea bag samples. A total of four types of Sujeonggwa in a tea bag were developed: two samples with varying amount of sugar, another sample using sugar and stevia and the last sample using sugar and short chain fructo-oligosaccharide as a sweetener. A commercial ginger tea and cinnamon tea were used as control products. Descriptive analysis was conducted on the same six samples and a descriptive panel identified its attributes. A total of 61 consumers evaluated acceptability using a nine-point hedonic scale and how they felt about intensities of the samples using a just-about-right scale. The results indicated that consumers liked Sujeonggwa samples in a tea bag more than commercial ginger tea and cinnamon tea.

The dried persimmon was effective in caring an inflammation, an ulcer and a burn and preventing hypertension and arteriosclerosis. At the Jejungsinpyun. dried persimmons gruel was beneficial to stomach and intestine and toned down voice. Based on Jejungsinpyuns and Sikryochanyo, dried persimmons gruel was developed for modern people. To standardize the dried persimmons gruel, physical properties and consumer acceptability was examined. The procedures of dried persimmons gruel was to make dried persimmons juice after soaking dried persimmons with same volume water during 24 hr and blending. To decrease the astringent taste of dried persimmons, dried persimmons juice and water with cinnamon (2%) was mixed and simmered during 3 min. Dried persimmons paste with cinnamon was added and the gruel was boiled more during 5 min. dried persimmons gruel was completed. The dried persimmons gruel were divided of 5 groups consisted of each 10, 15, 20, 25, 30 g dried persimmons. As dried persimmons content increased, lightness, apparent viscosity decreased. Acceptability test indicated the sample of dried persimmons : rice ratio at 2 : 5 had the highest overall acceptability and flavor. Considered to each, the sample of the dried persimmons : rice ratio at 2 : 5 met the purpose of the study.

This study examined the effect of waiting in a service queue on the evaluation of service quality focused on its overall process, mediators and moderators The conceptual model of this paper integrates key variables derived from previous studies of consumer waiting behavior. Data obtained from actual customers in service queue at a hospital was used to test the theoretical framework. First, results from the path analysis confirm that negative affect and acceptability of the wait function as mediators in the process that the perceived duration of the wait affects customer's evaluation of overall service quality. Second, the analysis of the data, with the use of moderate regression shows that disconfirmation of wait time expectations, transaction importance, stability of wait time and wait environment work as moderate variables for the relationship between perceived duration of wait and negative affect. For the relationship between perceived wait time and acceptability of the wait, on the other hand, only transaction import ante shows a significant effect as a moderator.
