Gochujang and red pepper powder are the representative condiments in Korea. This study examines gochujang sauces for tteokbokgi by hot taste degree(4 levels) and then evaluated the quality and sensory characteristics of gochujang sauces to provide the basic information for industrialization of gochujang sauce. Moisture content of gochujang sauce 1 was the highest (53.90%). Moisture content became decreased against hot taste. pH range of gochujang sauce was 5.50~5.84. pH values of sauces increased in accordance with hot taste. In the Brix contents, sauce 3 was the highest(46.73%), but the sauce 1 was a little low. Viscosity of sauce 4 was 237.93 cp and others became decreased in accordance with hot taste. In the lightness(L value), sauce 2 was the highest(24.89). Capsaicin content of sauce 4 was 27.00 mg/100 g while sauce 1 was 22.97 mg/100 g. In sensory evaluation, color of sauce 4 was darkest. In hot taste, sauce 1 was evaluated as less hot while sauce 4 as most hot. Overall acceptability score range of sauce 2, 3, 4 was 4.95~5.50 which was higher than sauce 1. The result of a research conducted to undergraduate students showed that they preferred hot taste gochujang sauce. Consequently, customers should be more satisfied with sauce products they chose when provided with those by hot taste degree. In the future, more studies are required about the degree of hot taste for the successful industrialization and globalization of hot pepper and gochujang.

This research aimed to Kimchi to be well known in the World, which to be international food on the each nation and each people, each religion cultural area, with having done Kimchi adaptation plan for localization. Among the plan, Kimchi utilization ways with the localization strategy in Turkish dietary life were investigated to the Kimchi preference, improvement points on Turkish view, for the Turkey person it would be able to apply in Turkish food culture, and the results are as follows. 1. According to sex of Chinese cabbage Kimchi preference, men ($M=3.75\;{\pm}\;0.89$) appeared higher than women ($M=3.62\;{\pm}\;0.88$). Color or appearance preference after Chinese cabbage Kimchi taste was investigated in order that red > burnish felt > transparent > yellow, and the smell preference which was hot($M=4.64\;{\pm}\;1.37$) appeared highest. A hot taste felt most intensely, and it was investigated in order that aftertaste> salty taste > sourness > off flavor taste > fermented fish source taste > sweetness> carbonic acid by the followings. For the feeling of texture of Kimchi, the crunch was higher than durable tough(it was visible the consider difference of the sex 2. That the Korean Kimchi hit to a palatable taste, against 109 people (72.2%) answered suitable appetite to this taste, and the reason which was in order of that hot tasty > appearance > chewing texture > red > fermented flavor was investigated. Did not hit to a taste 42 people (27.8%) answer back, with the reason that was investigated in order of hot tasty > appearance > red > fermented flavor > chewing texture. The hot tasty of Kimchi was commonly presented that hit and did not hit to appetite taste against people. 3. Among the Turkish food, similar foods for Kimchi were answered in order of Lahana Tursu (44.2 %) > Kapuska (25.9 %) > Lahana Prasa (11.1%), and similar food category were that Chinese cabbage or various vegetables to be pickling food and to be dressing salad with salt and vinegar. The accompanied or garnished Turkich food category for Kimchi were answered in order of cooking meat (34.1%)> steamed cooking rice (22.7%)> cooking fish (17.0%)> cooking soybean (14.2%). This result was same tendency with steamed cooking rice accompaniment for Kimchi in Korea and Turkey, and could be applied a new main menu like meat cooking and fish cooking dish which matched and accompanied with Kimchi.

The dried sea tangle added for soup prepatation to improved the taste in Korean and Japaness for long time. Attempts were made to develop the best procedures for extraction and removal of alginate by ultrafiltration and diafiltration. The summerized results of this study are as follows: 1) For hot water extraction in temperature range of 60～100$^{\circ}C$ for 4 hours, the higher temperature resulted higher yields in solids and protein. 2) Optimum sea tangle hot water extraction condition were 60～65$^{\circ}C$ for 1 hour which was cheap operating cost and high yield of good taste components. 3) The membrane flux was more higher GR 51 PP. and increase of flow rate permeate flow rate was accordingly increased. but limiting flow volume was 3.7 l/min. 4) It was found that ultration was relatively of higher recovery rate, solid and taste components, and low rejection coefficient rate than diafiltration.

The purpose of this study is to investigate the sensory characteristics of Toha-jeot added cabbage kimchi by Koreans and Japanese. The sensory evaluation was conducted for the following 9 items such as color, savory taste, carbonated taste, sour taste, hot taste, salty taste, off flavor, texture and overall preference. Sensory evaluation of kimchi was tested by Koreans or Japanese whose ages vary from 30 to 50 years old and each group had 25~30 evaluators. Kimchi at different stages of fermentation day 0, 10 and 18th was evaluated. Saltiness of kimchi was 1.5~2.1% through the fermentation period and pH of kimchis was decreased from pH 5.4~5.6 to 4.3~4.4 during the fermentation. The sensory evaluation of Toha-jeot added cabbage kimchi by Koran and Japanese showed the differences in evaluation as the fermentation proceeded. The color, texture and overall preference of Toha-jeot added cabbage kimchi fermentation for 10th days was scored significantly high by Korean group while the score for the savory taste was increased as the fermentation proceeded. The hot taste preference of Toha-jeot added cabbage kimchi fermented 18th days scored significantly high and also increased as the fermentation proceeded by Japanese group. The overall preference of Toha-jeot added cabbage kimchi by Japanese group was higher than that of control cabbage kimchi tested at 10 and 18th days fermentation.

In order to get a quantitative information of capsaicin intakes derived from Korean daily spicy food, capsaicin contents in powdered red hot peppers and powdered soup of Korean instant noodles were measured by high performance liquid chromatography. Capsaicin contents were 0.03~0.33mg/g in the powdered hot pepper, 3.67~5.50mg/g in the powdered soup with most spicy taste, 2.15~3.14 mg/g in the soup with medium level of spicy, and below 1.5mg/g in the soup with mild taste of Korean instant noodles. From the results, it was estimated that the amounts of daily intake of capsaicin from hot pepper were about 0.38~4.95mg/day, and capsaicin intakes from one pack of Korean instant noodles were about 10~60mg.

The physico-chemical properties of hot-water extracts of dried and roasted Boxthorn(Lycii fructus) were investigated. The proximate composition of dried Boxthorn was 17.5% moisture, 5.4% ash, 14.7% lipid, 18.9% protein, 11.8% fiber and 31.7% carbohydrate. As the roasting temperature and time increased, water soluble solids, turbidity, titrable acidity and redness of the hot water extracts were increased, while the free sugar content was reduced. The linoleic acid of roasted Boxthorn decreased and palmitic acid increased at higher roasting temperature. The sensory properties of sweet odor, burnt odor, sour taste, burnt taste and tannic taste of the hot water extract were scored higher and sweet and roasted taste were lower as the roasting temperature and time increased.

Effects of various sub-ingredients (hot pepper, garlic, ginger, green onion, leek, salted and fermented anchovy juice, and sugar) on the sensory quality of Korean cabbage kimchi were investigated. Sixteen sensory attributes were selected and their intensities evaluated by 20 panelists. The kimchi had an unbarmonized taste and unpleasant flavor when fermented with individual sub-ingredients, but had a well harmonized taste when fermented with all sub-ingredients. Hot pepper, ginger and garlic contributed to reduction of the unpleasatnt taste and moldy odor. The strong garlic flavor was reduced by adding green onion and leek. Salted and fermented anchovy juice gave a palatable taste, and the overall taste was improved by adding sugar. All sub-ingredients except sugar reduced the sour tasts.
