The evaluation of food taste is one of the important activities of human consciousness and it is practiced by sensory analysis using 5 terminal sensorial consciousness among many other functions. These consciousness activities may be conducted by 3 way branching transformation (3-WBT) logic, which choose one out of 3 options under the multi-layered consciousness decision making system. On the basis of this logic, cognitive sensory evaluation (CSE) method was developed to carry out questionnaire survey covering objective and subjective issues during consumption of food for pregnant women. The results of the CSE for several food items was presented with the Table-pattern called CSET covering consciousness factors and their effects on the food consumers.

Neohesperidin dihydrochalcone(NHDC) is an intense sweetener with lingering aftertaste, which limits NHDC to use as a sweetener in food products. This study was conducted to examine the changes of teste quality of NHDC when using $\beta$-cyclodextrin($\beta$-CD) as a taste modifier. A series of $\beta$-CD(0.01%, 0.03%, 0.1%, 0.176%) was added to NHDC solution (100ppm) and the taste quality was evaluated by magnitude estimation. It was found that $\beta$-CD produced a significant effect in the reduction of aftertaste of NHDC(p<0.01) and sweetness as well.(p<0.001). Linear regression(log mean magnitude estimate versus $\beta$-CD concentration) analysis showed that the intensity of sweetness(n=-0.31) decreased more rapidly than that of aftertaste(m=-0.17). This result suggests the possibility that $\beta$-CD may form inclusion complex with NHDC, so that the hydrophobic portion is encapsulated in the cavity of $\beta$-CD and the carbohydrate moiety is oriented to the outside of the cavity. Or it may be that $\beta$-CD competes with the NHDC molecule for binding to the taste receptor, resulting in reduced perceived intensity.

The purpose of this study was to evaluate the effectiveness of nutrition education and counseling on the salty taste assessment, nutrition knowledge and dietary attitude of 21 hemodialysis patients. Five times of the nutrition education and three times of nutrition counseling were performed for a period of 5 months. Biochemical analysis revealed that creatinine was significantly high (p < 0.001), blood urea nitrogen and serum albumin were significantly low (p < 0.05, p < 0.01) and Na, K, Cl, K, P and uric acid were not significantly different. The distribution rate of unsalty taste preference were significantly high and the distribution rate of salty taste preference were significantly low after nutrition education and counseling (p < 0.001). Nutrition knowledge significantly improved following 5th month of education and counseling (p < 0.01). Particularly, the scores for questions related to sodium were improved. The dietary attitude was significantly improved during the counseling period (p < 0.05). There were improvements in responses to 'use food exchange list on diet' and 'habitually add salt or soy sauce before the meal'. According to these results, salty taste assessment, nutrition knowledge and dietary attitude were significantly improved by the hemodialysis diet therapy practices of hemodialysis patients. Therefore, we conclude that there was a need for low-salt diet education and nutrition counseling to help them recognize the taste of low-salt foods and strive towards a preference for less salty tasting foods and the consumption of a low-salt diet.

This study was conducted to evaluate the prediction of sensory property of smoke from leaf chemical property and characterize leaf chemical components for the best tobacco taste's leaves in flue-cured tobacco. For analytical and sensory evaluations, one hundred and forty grades were used. The major leaf chemical components to predict the sensory property of smoke were nicotine for impact, irritation and off taste & odor, and total sugar/nicotine ratio for tobacco taste. Within ${\pm}20%$ range of difference, the predictable probabilities of sensory property of smoke form leaf chemical property were 80.0% for off taste & odor and $91.4{\sim}96.4%$ for impact, irritation and tobacco taste. As a result of K-means cluster analysis on the basis of tobacco taste, the desirable leaf chemical component contents were $2.77{\sim}3.55%$ in nicotine and $5.1{\sim}6.9$ in total sugar/nicotine ratio. This study suggest that the some regression equations may be useful to predict the sensory property of tobacco smoke from a few selected leaf chemical components in flue-cured tobacco and to select the flue-cured tobacco leaves for enhance the tobacco taste of cigarette.

The aim of this study is to identify the value structure of active seniors for noodles. Noodles are the secondly most preferred and familiar food in Korea, followed by rice. And noodles also have a variety of tastes/flavors and even a variety of ceremonial characteristics. The necessity of offering proper food to seniors has recently increasing because Korea becoming an aged society. This study conducted 1:1 in-depth interviews with 30 active senior participants using the soft laddering technique, which is based on the means-end chain theory. The Implication Matrix and HVM were derived from performing content analysis. The active seniors mainly consider the 'taste', expecting to obtain the 'satisfying taste', and pursuing the 'family affair', 'pleasure', and 'self-satisfaction'. The results of this study indicated that the taste is the most important attribute and the active seniors consider their family as well as the pleasure and satisfaction of their own. Male seniors mainly pursue the 'pleasure' and 'self-satisfaction' by satisfying their taste through considering 'taste' and 'familiarity'. But female seniors mainly pursue the 'family affair' by 'satisfying taste' through considering 'taste'. These results can be used as a basic data for developing noodle products for the elderly. This study will also contribute to the development of special care food and product concepts for the silver generation.

Objectives : Angelica Gigantis Radix is prescribed as the root of different Angelica species on the pharmacopoeia in Korea, Japan and China. Chemical components and their biological activities were also different according to their species. A study for the development of simple method to compare Angelica roots was needed. In order to classify them, the methods such as DNA sequencing analysis and taste sensor were applied to three Angelica species like Angelica gigas, Angelica acutiloba and Angelica sinensis. Methods : PCR amplification of intergenic transcribed spacer (ITS) region was performed using ITS1 and ITS4 primer from nine Angelica roots, and then nucleotide sequence was determined. Taste pattern of samples were measured using the taste-sensing system SA402B equipped with a sensing unit, which consists of artificial lipid membrane sensor probes of anionic bitterness, astringency, saltiness, umami, and cationic bitterness (C00, AE1, CT0, AAE, and AN0, respectively). Results : As a result of comparing the similarity of the ITS region sequences, A. sinensis was discriminated from the others (A. gigas and A. acutiloba). Equally this genetic result, A. gigas and A. acutiloba showed similar taste pattern as compared to A. sinensis. Sourness, bitterness, aftertaste of bitterness, astringency, and aftertaste of astringency of A. sinensis were significantly high as compared with A. gigas and A. acutiloba. In contrast, richness was significantly low. Conclusions : These taste pattern can be used as a way of comparison of Angelica species and this technic could be applied to establish a taste pattern marker for standardization of herbs in various purposes.

This study analyzed the Importance-Performance Analysis (IPA) of purchase behaviors and attributes for Hangwa. The data for this study were collected over 10 days from April 10 through April 19, 2013. For empirical research, married women over the age of 20 in Gwangju with buying experience of Hangwa were surveyed. A total of 172 questionnaires were completed and statistically analyzed by SPSS 18.0 package. Analysis rate was 96.6%. To review Hangwa purchase behaviors, most respondents bought Hangwa four or five times per year for memorial services or ancestral rites. Respondents bought Hangwa at big supermarkets and the types of Hangwa bought were Yukwa and Yakgwa. Their average expenses were 20,000 to 30,000 won per purchase. Among purchase attributes of Hangwa, respondents considered the importance of 'sanitation' (4.76 points) a top priority, followed by 'origin' (4.75 points), 'quality' (4.74 points), 'taste' (4.57 points) and 'appearance' (3.82 points). However in the case of satisfaction, 'sanitation' (3.85 points) was the most satisfying aspect, followed by 'package' (3.82 points), 'amount' (3.80 points), 'appearance' (3.51 points) and 'taste' (3.41 points). According to the IPA results, 'quality' and 'origin' purchase attributes, should be quickly improved. 'Sanitation' and 'taste' should be maintained. This survey found that satisfaction levels for Hangwa purchase attributes had a significant influence on overall satisfaction (F=29.11, p<.001), and especially 'taste' ($\beta$=.42, t=6.69, p<.001) had a meaningful effect on overall satisfaction. In addition, satisfaction levels for Hangwa purchase attributes affected repurchase intention (F=20.05, p<.001). From these results, Hangwa manufacturers should make efforts in product development to induce customers satisfaction and repurchase intention.

The purpose of this study is to examine the cognitive responses and the corresponding behavior responses of consumers who have experiences in not being able to buy a product in an online shopping mall due to it being sold-out. Responses were gathered from 526 consumers between the ages of 20 to 40 years residing in a metropolitan area. Each person surveyed had experienced a situation in which a product that they wanted to purchase from an online shopping mall was sold-out. SPSS 18.0 was used to perform frequency analysis, factor analysis, reliability analysis, and regression analysis. The first set of results of this study showed positive responses of quality, discernment, scarcity, but also negative cognitive responses of careless management, manipulation of shopping mall management, and common taste. In negative cognitive responses, sold-out situations caused consumers inconvenience. The second set of results revealed that quality, discernment, and careless management had a significant effect on product replacement (Substitute, S); likewise, factors such as quality, discernment, careless management, manipulation by shopping mall designers, and common taste had a significant effect on the delay of purchasing decisions (Delay, D). Scarcity, careless management, manipulation by shopping mall designers, and common taste also demonstrated significant influence on the incomplete leaving of stores (Incomplete Leave, L1), while discernment, scarcity, careless management, manipulation by shopping mall designers, and common taste had a significant influence on the complete leaving of stores (Complete Leave, L2). Previous studies have examined the behavioral response topics of substitute, delay, and leave. These study results suggest that product sellouts at online shopping malls did not have a solely negative effect on consumers. It actually had a positive effect in terms of discernment, scarcity, and the perception of quality of sold-out products. Furthermore, both positive and negative cognitive responses had various effects on behavioral responses.

사람들은 미각을 통해 음식물의 영양분과 안전성 여부를 파악하고, 이를 통해 식욕이 자극되고 만족되므로 미각은 음식물을 섭취하는데 필수적인 역할을 한다고 할 수 있다. 미각이 상실되거나 왜곡된 환자들의 경우 섭식 양상에 변화를 일으켜 건강에 나쁜 영향을 미치게 될 수 있다. 미각 기능에 영향을 줄 수 있는 요소는 매우 다양하며 미각의 장애 양상 또한 매우 다양하게 나타날 수 있다. 하지만 미각은 주관적인 감각으로 다른 감각들과는 달리 객관적으로 평가하기가 까다로우며, 맛을 느끼는데 있어서 미각뿐 아니라 후각, 촉각, 온도감각, 심리 상태 등 여러 다른 요소들의 영향을 받으므로 미각 이상을 나타내는 환자들을 진단하고 치료하는 것은 매우 어려운 일이다. 그러므로 실제 임상적 상황에서 미각장애의 평가를 위해서는 무엇 보다도 신중하고 철저한 병력청취와 임상적 증상의 분석을 통하여 환자의 상태를 정확히 평가하는 것이 가장 중요하다. 미각은 시각이나 청각과 같은 다른 감각에 비해 그 동안 주목을 받아오지 못한 분야였으나, 사회가 발달함에 따라 삶의 질을 중시하게 됨으로써 최근 미각 장애로 내원하는 환자가 증가하는 추세이다. 본 연구의 목적은 미각 장애를 주소로 내원한 환자들의 임상적 특성을 분석하는 것이다. 미각 장애를 주소로 2005년 11월부터 2008년 8월까지 서울대학교 치과병원 구강내과에 내원한 환자 50명(남 12명, 여 38명, 평균 연령 $53.6\;{\pm}\;14.7$ 세)을 대상으로 하였다. 상담을 통하여 현재 미각 장애의 증상과 관련된 사항들과 그 밖의 의과적 치과적 병력, 투약, 미각 장애 외의 구강 증상들에 대하여 조사하였으며, 구강 검진, 설문지 작성, 방사선 사진 촬영, 혈액검사, 타액분비율 측정 검사 등의 임상적 검사를 시행하여 다음과 같은 결과를 얻었다. 1. 미각 장애 환자들 중 구강 점막의 통증 혹은 작열감을 호소한 환자가 36명(72%)이었다. 이들 중 구강점막에 특별한 병소를 보이지 않는 구강작열감증후군으로 진단된 환자는 18명(36%)이었다. 2. 전체 환자들 중 19명(38%)의 환자가 주관적 구강건조감을 호소하였으며, 타액분비율 측정 결과 비자극시 타액분비율이 0.1 mL/min 이하인 환자는 14명(28%)이었고, 자극시 타액분비율이 0.5 mL/min 이하인 환자는 17명(34%)이었다. 3. 미각 장애의 종류로는 미각감소(hypogeusia)가 25명(50%)으로 가장 많았으며, 미각왜곡(dysgeusia)이 18명(36%), 환상미 각 (phantogeusia)이 15명(30%), 미각과민(hypergeusia)이 10명(20%), 미각상실(ageusia)이 5명(10%) 이었다. 전체 50명 중 19명(38%)의 환자가 두 가지 이상의 미각 장애의 종류를 나타내었으며, 가장 많은 조합은 미각왜곡과 미각감소를 같이 보이는 경우였다. 4. 미각 장애의 원인이나 관련요인은 병력조사와 임상검사를 토대로 평가하였으며, 구강점막질환이나 원인불명인 경우가 각각 9명(18%)으로 가장 많았다. 그 밖에 심인성이 8명(16%), 약물이 7명(14%), 구강건조증이 6명(12%)으로 나타났으며, 이 5가지의 항목이 전체의 78%를 차지하였다.
