The quality of Yukwa added with safflower seed powder (SSP) was investigated using chemical, sensory and mechanical properties, The result of chemical properties showed that degree of expansion of Yukwa were decreased as the amount of SSP increased, while fat absorption increased. Yukwa with 1% SSP was the best in appearance, taste and overall preference of acceptability. Lightness decreased by the addition of SSP, while redness and yellowness increased. Texture measurement showed that hardness was the lowest in the Yukwa with 5% SSP, and cohesiveness was the highest in the Yukwa with 1% SSP. Hardness and brittleness of mechanical properties were positively correlated with the acceptability. The degree of expansion was positively correlated with cohesiveness and springiness. Fat absorption and moisture content were positively correlated with gumminess in the mechanical properties. Yukwa with 1% SSP showed a good overall preference.

Doenjang, traditional Korean soybean paste without soysauce and soondoenjang that was not isolated soysauce from soybean paste were thermally processed by the addition of dry anchovy, garlic, red pepper powder and green onion. The volatile flavor components generated from doenjang soup and soondoenjang soup were studied and compared with the change in the various flavors. It was confirmed that some difference of the flavor components was found in two type of soups. Doenjang soup contained a plenty of aldehydes and ketones that revealed the savory flavor. The major flavor components in the soondoenjang soup were sulfur containing compounds that appeared the highest ratio than any other types of flavors and 10 pyrazines. On the sensory evaluation, a great number of pyrazins may be considered as a characteristic of the savory flavor of soondoenjang soup, however, it was not give the reliable result. Stepwise multiple regression analysis of two type of soups indicated that aldehydes, alcohols, ketones were contributory flavor components for overall smell preference and quality preference.

The purpose of this study was to analyze the chemical components of Perilla leaf(frutescens Britton var. scuta Kudo) according to the making process, and to examine Hunter's color value and sensory evaluation of Jasosuksu by extraction time. Perilla leaves were prepared in three types; fresh leaf, dried leaf in the shade and roasted leaf after being dried in the shade in order to make Jasosuksu. The results of the research were as follows: Free sugars(sucrose, glucose, fructose) and organic acids(citric acid, tartaric acid, malic acid, succinic acid) were present in the fresh leaf, dried leaf and roasted leaf. $15{\sim}16$ kinds of amino acid including aspartic acid were determined in the fresh leaf, dried leaf and roasted leaf, and the major free amino acids were serine, aspartic acid, and glutamic acid. The major total amino acids of tile fresh leaf, dried leaf and roasted leaf were glutamic acid, histinine, and glycine. The major fatty acids of Perilla leaves were palmitic acid, linolenic acid, and linolenic acid. The content ratio of linolenic acid in fresh leaves was the highest, but that of palmitic acid was lower than that of dried leaves and roasted leaves. L value, a value, and b value of Perilla leaf were the highest in the roasted leaves followed by the order of dried leaves and fresh leaves. L value and b value of Jasosuksu extracted from roasted leaves were higher than Jasosuksu extracted from dried leaves. The preference of color, flavor, sweetness of Jasosuksu extracted from dried leaves was the highest when extraction time was 10 min. at $70^{\circ}C$, but that of Jasosuksu extracted from roasted leaves was the highest when extraction time was 15 min. at $70^{\circ}C$. The preference of color, flavor, taste of Jasosuksu extracted from roasted leaves was higher than that of Jasosuksu extracted from dried leaves.

Fruit quality is essential for increasing marketability and consumer acceptance. To suggest an easy method for measurement of squash fruit quality, 10 varieties/cultivars and 1 populations were used as experimental materials. The fruits were harvested in marketable maturity to investigate the relation between quality factors and sensory test. The total solids content is one of the most important factors associated with sensory taste in fruits. The major squash varieties/cultivars such as 'Puthobag', 'Seoulmadi', 'Aehobag 1', 'Aehobag 2', 'Ford Zucchini', and 'Zucchini' showed total solids content of 6.4, 7.5, 7.3, 5.8, 4.7, and 4.30%, respectively. The preference values for 'Puthobag', 'Seoulmadi', 'Aehobag 1', and 'Aehobag 2', which are generally preferable varieties/cultivars, were 4.6, 4.7, 4.8, and 4.3, respectively. On the other hand, the preference values for variety 'Ford Zucchini' and cultivar 'Zucchni', which are not generally preferable, were 1.6 and 1.4, respectively. There was no significant correlation between plant length and total solids content or starch content in the fruits thereby suggesting the possibility of breeding bush type squash cultivars with good taste. This easy method of weighing dry matters of squash fruits might be useful for marketable quality index.

We have got the following results from tests in the course of time retrogradation and taste change in bread with added flour of Angelica keiskei Koidz, which had been stored in room temperature (27±2oC), refrigerating(2±1oC) and freezing( 20±1oC), respectively. Bread with the added flour showed a little lower degree of retrogradation than control group, and every group in room temperature retrograded from the very first day. The degree of retrogradation of the group in refrigerating was far greater comparing with the group in room temperature. The longer bread was stored, the lower the degree of retrogradation was, and the higher the adding rate of the flour got, the later its retrogradation happened. Especially the flour of this vegetable's stem turned out to be the most effective in retarding its retrogradation. Group stored 30 days in freezing didn't show a wide difference in retrograde comparing with the group before storage. Preference for color and shape of the flour added bread stored in room temperatue, refrigerating and freezing did not change significantly from the group before storage. Although preference decreased for flavor, texture, mouth feel and overall quality with the lapse of time, flour added group improved in preference for these factors comparing with the control group. Above all, added flour of pretreated stem proved to be the most effective in the sensory tests. With respect to the storing method, the group stored in refrigerating showed greater preference for the texture and mouth feel over the groups in room temperature and freezing. Flavor preference of the group in freezing was the lowest of all.

The effect of baking on the consumer perception and sensory characteristics was investigated using a model system of cookies incorporated with strawberry powder as a value-added food ingredient. Strawberry powder was incorporated into cookie dough at 4 levels (0%, 2%, 4%, and 6%, 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 15 min in an oven. The baked cookies were cooled to room temperature for 1 h and packed in airtight bags prior to all measurements. In terms of color, control received the most favorable mean score, which is significantly higher than others (p<0.05) followed by the 4% sample. The consumer preference on taste and aftertaste was not significantly affected by the amount of strawberry powder incorporated in the formulation (p>0.05). Samples with 4% strawberry powder received the highest mean flavor score of 6.28 which is significantly higher than that of 6% sample (p<0.05). In overall, substitution of 4% strawberry powder in the formulation would result in the most favorable strawberry cookies by the consumers with taking advantages of health benefits of strawberry. Correlation analysis indicated that strawberry powder concentration was significantly correlated positively with sensory color and hardness and negatively correlated with consumers' overall acceptability (p<0.05). Consumers' aftertaste was significantly correlated with overall acceptability which was negatively correlated with sensory hardness (p<0.05). Sensory hardness was highly correlated with sensory color attribute (p<0.05).

This study was conducted to evaluated the sensory properties of Miyukgook, Korean seaweed soup, with gamma-irradiated Undaria pinnadifida for enhancing the storage of the harvested seaweed. The harvested seaweed was irradiated at the doses of 1, 3, 5, and 10 kGy. The Miyukgook was made by following the general recipe. The values of pH and acidity of the Miyukgook were not changed by the irradiation of harvested Undaria. The sensory evaluation result showed that the preference scores in all the sensory properties was a little decreased when it was irradiated, but sensory score of less than 5 kGy samples was similar in all terms. Therefore, it was considered that gamma irradiation with less than 5 kGy was effective for improvement of the storage stability of U. pinnatifida without the changes in the sensory of its major cooked food, Miyukgook.

This study comparatively analyzed the images and preference of lighting space using the emotion-based technique in order to effectively use it in clothing shops and fashion marketing. In terms of color temperature for light sources, 2,800K of lamp color, 6,500K of daylight color and 4,200K of white color were used. For the assessment, sensory evaluation technique was used. Then, the study found the followings: In terms of the image of lighting space by light source, different images were observed by light source with significant difference by the evaluation category. For factor analysis by the evaluation category, 7 factors were extracted. Among them, evaluation on lighting space was influenced by the following three images: modern space, elegant space and classical space. In particular, the modern space comprised of the following adjectives had the biggest effect on the assessment of the image of lighting space ('refreshing,' 'transparent,' 'bluish,' 'bright' and 'non-classical') (primary evaluation 30.13%). According to assessment on the preference of lighting space, the respondents' most favorite lighting space was 4,200K while their least favorable one was 6,500K in terms of color temperature. In terms of preference by the image of lighting space, they didn't like 'non-elegant' and 'non-beige' images even though they had the images of modern space. Therefore, it was confirmed that beige and elegant space images have an effect on the preference of lighting space.

The sensory quality describing terms of Takju were surveyed by questionair and classified according to the sensory characteristics. The effects of thermal treatment for the pasteurization of Takju on the sensory quality were tested and statistically evaluated. The important sensory quality attributes of Takju were white, gray, and yellow for color, acidic and yeasty for smell, sour, astringent, bitter and sweet for taste and gritty, viscous and carbonated for mouthfeel. The organoleptic properties of grayness, yeasty and cooked smell, astringent and bitter taste and thickness increased, while sourness, sweetness, yellowness, grittiness and carbonated feel decreased by the pasteurization treatments, heating $82^{\circ}C$, $93^{\circ}C$ or $135^{\circ}C$ for 9 seconds. These changes coincided with the overall reductions in the preference scores of pasteurized Takju. The degree of sensory quality deterioration appeared to be affected to some extent by the heating temperature.
