The purpose of this study is to compare preferences of consumers between food items made from modified cassava flour and plain flour using sensory tests. This study is a qualitative research with an experimental approach and four food items, namely streamed brownies, cookies, fried mushrooms, and seasoning flour have been used for the study. Each of these food items are made from modified cassava flour and plain flour. Panelists wore blindfolds and tasted the food items except the seasoning flour. Based on the data analysis, the panelists have different preferences towards the four food items. The result of the paired Wilcoxon test showed that there is not any different preference in terms of taste of steamed brownies made from mocaf or plain flour, while there is a significant difference in terms of color, aroma, texture, and appearance between the steamed brownies made from mocaf and plain flour. Consumers decide to buy products made from mocaf because these products use local flour and are gluten-free. This article describes the customer's preference based on sensory analysis between products made from mocaf and ones made from plain flour. The result can be used as the basis for developing food items made from local flour and alternative food for customers allergic to gluten.

The purpose of the study was to examine the effect of motif categories and motif colors on evaluating sensory image of fashion materials with the gestalt theory as the background. The research was conducted on a quasi experimental basis, with subjects numbering 187 male and 207 female college students. Data were collected in the period from march 19th to march 31st, 2007. A set of fabric stimuli and semantic differential scales were developed. The stimuli were thirteen fabric species(each measuring 12 by 13cm). Variables included; (a) motif colour(white, grey, pink and blue) (b) motif categories(plain, paisley, flower, stripes and zebra effect). The semantic differential scale to measure sensory image of fabric stimuli included 23 sets of bi-polar adjectives. The data were analysed by factor analysis and ANOVA and the major finding were as follows. 1) Four sensory dimensions emerged of importance: salience, attractiveness, comfort and softness. 2) The motif category effected on the four sensory image dimensions while the motif colour effected on salience, comfort and softness sensory dimensions. 3) An interaction effect was founded between motif category and motif colour. 4) Motif category showed significant effects on the preference and liking of the fashion, however the motif colour did not show any significant effects on the preference and liking. As a whole the results supported the gestalt theory and the results can be used for the marketing strategy for developing fashion fabrics.

Herbs have unique tastes and flavors, and they have been used in western foods. This study used herbs to make cookies. The purpose of this study was to investigate the sensory characteristics of cookies with rosemary(1, 2, 3, 4%) and mints(1, 2, 3, 4%) after foretasting herbs. The sample of this study was 880 college students which consisted of 436 males and 444 females. The results of this study were as follows. This study was conducted to find a high quality product through a sensory test with rosemary and mints. First, in terms of foretasting experience, the respondents had tasted 12 herbs. 65.2% of them preferred parsley, followed by mint(45.2%), bay leaf(44.0%), rosemary(28.3%), basil(21.8 %), etc. Second, in terms of the most important items while making herb added to bread and cookies, taste was high with 45.8%, flavor 27.3%, price 10.1%, nutrition 8.5%, etc. There were significant differences between genders and among majors(p<0.001). Third, it was found that appearance was high with 2% added group(M=6.00) in terms of sensory preference. The flavors, tastes, texture, overall acceptability were high with 1% added group in terms of sensory preference of cookies with rosemary. The respondents showed low preference for cookies with mints. While the 1% added mint group showed the highest preference for appearances and texture, the control group showed the highest preference for flavors, tastes and overall acceptability. There was a significant difference in appearances and tastes on all samples except colors and taste of rosemary added cookies $(p<0.05{\sim}p<0.001)$. Fourth, males preferred 2% rosemary added one in appearances and tastes in a sensory test. They preferred the 1% rosemary added group in terms of flavors, texture, and overall acceptability. Females preferred appearances of cookies with 2% rosemary and also preferred flavors, tastes, texture and, overall acceptability with 1% rosemary. Both of them less preferred 4% mint added one. Overall, this study found that respondents preferred 1% rosemary herb cookies. There should be further researches with less than 1% mint to make herb cookies.

Pork quality is determined by several attributes, among which odor and taste are the utmost significant. Therefore, this study was aimed to assess the effects of boar odor hormone concentration on the quality traits and sensory acceptability of pork. A total twenty-six (26) non-castrated 3-way crossbred (Landrace × Yorkshire × Duroc) pigs were selected with an average body weight (ABW) 115.6 kg before to slaughter. The three treatment groups (low, medium and high) were divided according to the androstenone concentration. In experiment 1, for meat quality traits carcass was selected based on androstenone concentration: low (LC, 0.64-0.69 ㎍/g, n = 9), medium (MC, 0.70-0.99 ㎍/g, n = 7) and high (HC, 1.00-1.69 ㎍/g, n = 10). In experiment 2, for sensory evaluation carcasses were also selected based on the abovementioned conditions. Results revealed that androstenone concentration not effect on proximate components, meat quality traits and fatty acids except palmitoleic acid. Sensory evaluation data showed that boar taint and meat boar taint were significantly increased in a concentration-dependent manner from low to high, whereas, gravy and meat flavor preference were significantly increased in LC group than HC group. In addition, correlation analysis showed that boar taint and meat boar taint were positively, and gravy and meat flavor preference were negatively correlated with boar taint hormones. In essence, our findings indicate that androstenone concentration had no effect on meat qualities, but a high concentration of androstenone had a negative effect on the sensory characteristics in uncastrated pigs.

The effects of baking with broccoli powder on the consumer perception and sensory characteristics were investigated using a model system of cookies incorporated with broccoli powder as a value-added food ingredient. Broccoli powder was incorporated into cookie dough at 5 levels (0%, 1%, 2%, 3%, and 4%, w/w) by replacing equivalent amount of wheat flour of the cookie dough. After aging and sheeting, cookies were baked at $170^{\circ}C$ for 8 min in an oven. The baked cookies were cooled to room temperature for 1 hour and packed in airtight bags prior to all measurements. Control received the most favorable mean score, which was not significantly different from samples with 1% broccoli powder for color preference (p>0.05). Results of the consumer preference on taste showed a similar trend. Consumers did not find any significant differences on aftertaste and flavor among samples prepared by replacing wheat flour with up to 2% broccoli powder (p>0.05). Overall, incorporation of 1% broccoli powder in the formulation would result in the most favorable broccoli cookies for the consumers without sacrificing the sensory qualities, while still taking advantages of health benefits of broccoli. Correlation analysis indicated that broccoli powder concentration was significantly negatively correlated with the consumer preference for color, taste, aftertaste, flavor, overall acceptability and positively correlated with sensory color, taste, and flavor (p<0.05). Consumers' color, taste, aftertaste, and flavor were well correlated with the overall acceptability (p<0.05). Sensory intensity results are also presented.

We examined the quality characteristics and texture of Jokpyuns with chicken and codfish. In proportion to the increase of water addition, the color became lighter and the texture characteristics decreased in So-Jokpyuns, which were prepared with cow feet. The texture and taste had an influence on overall preference of So-Jokpyun. Yongbon-Jokpyun which was prepared with cow feet and chicken was much preferred to So-Jokpyun in the appearance and texture, and showed a similar preference with So-Jokpyun. However, Sodaegu-Jokpyun which was prepared with cow feet and codfish was not preferred to So-Jokpyun in all items including appearance and texture, and the overall preference was remarkably low. Overall preference of Yongbong-Jokpyun and Sodaegu-Jokpyun was greatly related with the preference of taste and flavor. The lightness and the degree of yellow color of Yongbong-Jokpyun were higher and the degree of red color was lower than So-Jokpyun. On the other hand, the results of lightness, degree of red and yellow color in Sodaegu-Jokpyun were opposite to those of Yonsbong-Jokpyun. In case of the hardness, Yongbong-Jokpyun was the lowest and Sodaegu-Jokpyun was similar with So-Jokpyun. Adhesiveness of Yongbong-Jokpyun and Sodaesu-Jokryun was lower than that of So-Jokpyun. There was no difference in the springiness and cohesiveness among 3 kinds of Jokpyun.

This study examined the characteristics of Sulgidduk with different amounts of apios powder (0, 10, 20, 30, and 40%). The moisture content of Sulgidduk significantly increased with the addition of apios powder. Also, the pH values of Sulgidduk significantly decreased with the addition of apios powder. The addition of apios powder in the Sulgidduk decreased the lightness (L) in Hunter's color value, but increased the redness (a) and yellowness (b). By increasing the quantity of apios powder, the hardness, gumminess, and chewiness of Sulgidduk decreased and its springiness increased. The addition of apios powder in the Sulgidduk increased the total polyphenol content and DPPH-radical-scavenging activity. In the sensory evaluation, the addition of 20, 30% apios powder had the best score in taste and overall preference. This study suggests that apios powder is an excellent ingredient for improving the sensory preference and functionality of Sulgidduk. The study also shows that it was the addition of 30% apios powder can be used to make functional Sulgidduk.
