This study investigated the quality characteristics of cookies containing capsaicin, the main source of spicy taste in pepper, which is well known for its various functions such as anti-oxidant, anti-cancer, anti-inflammatory, and anti-obesity activities, as well as pain-relief effect. Cookie samples were made by adding the capsaicin powder at different levels, including 40 mg% (C1), 85 mg% (C2), and 150 mg% (C3). In this study, measurement of the moisture, pH, color, spread factor, hardness, anti-oxidant activity, and sensory evaluation of the cookies was carried out. The results showed that the anti-oxidant activity increased when more capsaicin powder was added to the cookies (p<0.001). The moisture also increased with increasing capsaicin powder content (p<0.05), while the pH did not show any significant changes. As for the colors, the L value and b value decreased as more capsaicin powder was added, while the a value increased. The spread factor also increased significantly with the increase of capsaicin powder (p<0.01). Although the hardness increased with capsaicin powder content, no statistically significant differences were observed among the various cookies. In the sensory evaluation, Cookies containing 40 mg of capsaicin obtained the highest score in color, while cookies containing 150 mg of capsaicin showed the highest score in taste, texture, and overall acceptability.

The purpose of this study was to survey the perception and preference for Korean food among Chinese students residing in Korea (Chinese foreign students, N=69) and China (Chinese-locals, N=98). A total of 76.8% of Chinese foreign students and 70.4% of Chinese-locals had ever eaten Korean food in China before visiting Korea, and motivation to try Korean food at first was 'easy access to Korean food restaurants' (Chinese foreign students 38.6%, Chinese-locals 44.9%). The most important factors in selecting Korean food were 'taste' and 'price' (Chinese foreign students 72.7% and 18.2%, Chinese-locals 59.1% and 22.7%, respectively), and needed improvements for Korean food were 'spicy and salty taste' and 'nutritional aspect' (Chinese foreign students 54.5% and 25.8%, Chinese-locals 33.3% and 36.4%, p<0.05). The scores for perception of Korean food were significantly lower in Chinese-locals (2.99) than in Chinese foreign students (3.31)(p<0.001). Chinese foreign students preferred Bulgogi (20.5%), Neobiani (20.1%), and Galbijjim (17.9%), whereas Chinese-locals preferred Bulgogi (16.1%), Gimbap (16.1%), and Samgyetang (15.2%) (p<0.001). The most preferred condiment was 'Garlic' (18.0%) in Chinese foreign students, and 'Red pepper powder' (16.4%) in Chinese-locals. The results of the study can be used as a foundation to prepare a globalization strategy for Korean Food.

To investigate the market potential for developing Gochujang(a traditional Korean hot pepper soybean paste) products in the UK including the European market, a qualitative consumer study utilizing focus groups was conducted on the $23rd{\sim}25^{th}$ of May, 2005. The focus group approach utilizes small groups of consumers and is very effective in determining the ways in which a product can be used, by examining consumer perceptions on the overall sensory properties of a product as well as variations in taste, flavour, and texture. A series of six consumer group studies were carried out in three different locations around the UK. Each group involved approximately eight respondents(a total of 48 respondents) and ran for at least 90 minutes. The respondents were recruited by specific criteria to achieve a cross-section of ages and genders. All respondents purchased, prepared, and ate home-cooked Oriental/Far Eastern cuisine. Consumer reactions to Gochujang in its traditional form, and in manufactured products, were explored in terms of appearance, texture, flavour, and taste the consumers' perceived uses and applications for products were also examined. Many consumers were familiar with ethnic cuisines such as Chinese, Thai, Japanese, Indian, and Tex/Mex, already preparing these foods using various convenience products at home at least twice a week. However, Korean cuisine was not mentioned by any of the respondents. The Gochujang sauce presented during the interview had broad based appeal mainly as a dipping sauce, and to a lesser degree as a marinade. Traditional Gochujang has the potential to inspire consumers who are looking for novel and authentic world cuisine products. From the sensory evaluations of various prototypes developed according to consumer reactions during the focus group interviews, three prototypes(a sauce for chicken, dipping sauce type, and BBQ sauce type) were determined for further consumer preference studies.

The characteristics of Kimchi, associated with proceeding velocity of fermentation, and microbial changes, were investigated during fermentation where kimchi were prepared by the addition of different kinds of minor ingredients. In all samples, total acidity increased, and the pH and total reducing sugar content decreased as the fermentation proceeded. Redox potentials decreased from early to middle fermentation period but thereafter increased and had the lowest value at optimum ripening stage. The counts of total viable and lactic acid bacteria increased rapidly at the begining and decreased slowly. These bacterial counts of kimchi samples containing ginger, red pepper powder, and mixture of all minor ingredients were higher than those of other samples. The number of Leuconostoc mensenteroides reached the maximum at the optimum fermenting stage, Lactobacillus plantarum appeared at the time when Leu. mesenteroides reduced. All these phenomena were observed earlier in the samples containing raw red pepper and later in the samples added garlic than in other samples. It is suggested that garlic is the ingredient which improved storage capacity by prolonging fermentation period by lactic acid bacteria beneficial to less acidification, and ginger and red pepper powder are materials which gave better taste to kimchi by stimulating the growth of Leu. mesenteroids. And redox potential was an useful indicator in choosing optimum ripening time during fermentation.

In order to determine optimum condition for the Ko-Choo-Jang (red-pepper-paste) processing, chemical analysis, mixed ratio, and sensory teat, resulted as follows. 1. The best nutritional value could be obtained after three hours at $60^{\circ}C$, which proved to be the optimum temperature in koji digestion of starch paste. 2. The component ratio of wheat flour to koji-powder was two to one giving the best digestion. 3. The mixing ratio of salt and red-pepper-powder and flour-koji was determined as 1 : 1.5 : 3 by sensory tests. 4. The highest reducing sugar content appeared in a digested mixture using glutinous rice as a starch source and the reducing sugar increased continuously with decreasing, total sugar content in almost every mixture of starches. 5. As a starch source, glutinous rice powder produced the highest total sugar in the beginning stages, however, after 10 day's curing produced less sugar than rice powder. 6. The order of total nitrogen content in the cured paste was recorded as wheat-flour, rice-powder, corn-powder, glutinous-powder, barley-powder, and sweet potato-starch. 7. Amino-nitrogen was increased with curing and the highest, value was observed in the case of wheat flour. 8. In sensory test, Ko-Choo-Jang made of glutinous rice-powder resulted in the best taste.

This study was conducted to examine the favorable taste of food color for one month of November 1991 With 200 college students consisting 100 male and 100 female students. The color to examine the favorable food was based on Munsell color standard of ten colors such as F. Birren seven colors (red, orange, yellow, yellowish green, green, blue and violet), brown, pink and black. And then, the data of this study was analysed by using frequency(%), mean values, standard deviation, t-test, Chi-square, Spearman correction with SAS Package on the basis of 100% collection and reliable coefficient alpha= .775. The result of this study is summarized as follows. 1. It was shown that the male college students (59%) showed remarkable interest in the food color higher than that of female college students (92%), and that 85% of male students and 97% of female students considered that the food color has an effect on appetite. In addition, the food name having an effect of the food color on appetite appeared in such order as carrot (13.0%), apple (10.9%), spinach (7.0%), cucumber (6.0%) and red pepper (5.6%). The important factor in choosing the favorable food was the taste for both male and female college students, while the male and female students considered the food color as the 4th, respectively, and the 3rd important factor in choosing the favorable food. 2. The favorable food color appeared in order such as orange, red, yellow, yellowish green, green, blue, violet, pink, black and brown colors for the male college students, and in order such as red, orange, yellow, green, yellowish green, brown, violet, black, pink and blue. Also, there was difference between the male and female college students in such colors as brown, yellowish green, blue and pink. It was also shown that there was no relation between the male and female college students in examining the order of favorable food colors and general colors when selecting null hypothesis (ASE: .405). The food name associated with the color was apple for red color, orange for orange color, coffee for brown color, banana for yellow color, lettuce for yellowish green color, spinach for green color, mackerel for blue color, eggplant for violet color, sausage for pink color and bean for black color 3. The favorable color combination of both male and female college students showed red with green, orange with yellow, yellow with green, green with yellow, pink with violet and black with black. In addition, the favorable combination of the male college students indicated brown with black, yellowish green with orange, blue with red and violet with yellow while the female college students did brown with yellow, yellowish green with green, blue with yellow and violet with pink. The favorable combination color showing difference between the male and female college students included orange, brown, violet, pink and black colors. 4. The relation between the food color and terms of favorable taste showed that “light and mild color” is yellow, that “untasty color” is black, that “sourish and puckery color” is orange, that “bitter color” is violet, that “hot color” is red, and that “fresh color” is green which were answered by both male and female college students. However, the male and female college students considered yellow, respectively, and orange as “tasty color”, and black and yellow, respectively, as “sweet color”. Then, the taste term showing difference between male and female college students included “light”, “mild”, “sourish”, “tasty” and “sweet”. Based on the above result of this study, it is apparent that there is a close relation between the food color and appetite while being difference between the general color and taste. In addition to this fact, there is also some differences between male and female college students in the taste of food color.

Physicochemical and sensory characteristics of Kakdugi substituted red pepper powder with red paprika powder during fermentation at 1$0^{\circ}C$ were compared with those of the control. The fermentation patterns of two Kimchies were similar. While the pH and the acidity of the control were 3.88 and 0.691%(as lactic acid), respectively, those of paprika, 3.85 and 0.690%(as lactic acid), respectively on the 10th day of fermentation, which is the optimal ripe time. Reducing sugar content and Lactobacilli number of paprika Kakdugi were higher than those of the control. The hardness and fracturability of Kakdugi radish were not significantly different from those of the control during fermentation. The Hunter color L, a and b values of both Kakdugies increased gradually until l0th day and then decreased. The a and ASTA value of paprika Kakdugi was higher than that of control, which is consistent with the results of sensory evaluation. Capsaicin and dihydrocapsaicin analyzed by HPLC were not detected in paprika Kakdugi. Sensory evaluation (unstructured scale, 10 points) showed the score of hot taste f3r paprika Kakdugi was lower than that of the control(p<0.05), whereas the score of over-all acceptabillity for paprika Kakdugi(8.0) was higher than those of control(6.1).

The Chinese Sigyeong records the foods of the Primitive Pickling Period, pickling being a universal vegetable storage method, but does not indicate the origin of the pickled vegetables or the location of the source of transmission. Kimchi mainly used salt and sauce-based soaking materials at the beginning of the Fermented Pickling Period (beginning in the 1st to 3rd centuries A.D.), and it differed from the Chinese method, which used alcohol and vinegar. In the Umami-Flavored Pickling Period (beginning in the 14th and 15th centuries A.D.), jeotgal, fermented seafoods, were added, and pickles with a completely new identity were created, one different from any other pickles in the world. Lastly, entering the Complex Fermentation and Pickling Period (beginning in the 17th and 18th centuries), the technical process evolved using a separate special seasoning containing red pepper as the secondary immersion source after pickling in brine, the primary immersion source. As a result of this, kimchi was transformed into a food with a unique form and taste not found anywhere else. The unique characteristic of kimchi is that the composition of original materials, a combination of salted marine life and vegetable ingredients, is its core identity, and there is a methodological difference in that it is completed through a second process called saesaengchae (生菜)-chimchae (沈菜).
