The present study attempted to conceptualize Korean typical tastes, flavors and foods and to gather professionals' opinions about the globalization of Korean foods. A total of 23 experts participated in a three round survey using the Delphi technique, which was used to integrate and share the professional ideas of each expert. The survey was categorized into two parts: 1. Korean typical tastes and flavors, 2. Korean typical foods. According to the results, 'hot chili pepper', 'Kimchi', 'soy sauce', and 'garlic' were represented as Korean typical tastes and flavors. Also 'harmonized' was determined to be a type of food that should be introduced to foreigners and, 'sweet' and 'tart' were shown to also be liked by foreigners. In addition, 'neobiani', 'kalbi', 'bibimbap', 'kimchi', 'japchae', and 'neobiani' were categorized as typical Korean foods, foods that should be introduced to foreigners, and foods that would be liked by foreigners. These results showed that appropriate foods should be globalized and R&D should be expanded to determine the preferences of foreigners in terms of tastes and flavors.

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.

This dissertation aims to study the five tastes in the Yellow Emperor's Canon of Internal Medicine. Medicinals as well as Foods are classified by the five tastes: sweet, sour, bitter, salty and pungent, which can be tasted by the tongue. With the development of the theory dealing with the medicinal properties, some flavors are summarized out of clinical actions of medicinals, therefore, there is a little difference between the flavors of medicinal herbs and the tastes got by tongue. Each taste acts on or has direct influence on a specific vital organ, and each of which has different physiologic actions. Taste also has a long-term or post digestive effect on the body and its metabolism. When each taste is consumed in moderation, it benefits the corresponding organ. Over-indulgence in any taste harms the organ and creates imbalance among the five vital organ systems. The Korean medicinal herbs with same flavor mostly possess similar actions while the medicinal herbs with different flavors show different actions in the treatment, which are shown as follows. Sour has absorbing, consolidating and astringent actions and acts on the liver. Bitter has the actions of drying or resolving dampness, purging and lowering and acts on the heart. Sweet has the nourishing, harmonizing and moistening actions and acts on the spleen. Pungent has an action of dispersing and promoting circulation of gi and blood and acts on the lungs. Salty has the effects of softening hard nodes or masses and promoting defecation, etc and acts on the kidneys. The five organ systems control and support each other. Proper coordination only exists when there is no one organ stronger or weaker than the rest. Since the five tastes have direct influences on the five organs, the diet we take should have a good combination of the five tastes in order to promote internal balance and harmony. They control our well-being and create dietary balance. Excessive consumption of any of these could result in adverse effects. In a word, when the properties of the five tastes respectively are distinguished, their natures and flavors cannot be separately considered. I think the harmonization of food and medicinals should be stressed on good nutritional diet to maintain good health. The traditional belief that food and medicine share the same origin is a part of Korean medicine tradition.

The consumer acceptance of food is not only affected by the sensory characteristics of food but also by the non-food factors, including food experience, consumption frequency, and food attitudes. Therefore, food attitude scales such as the food neophobic scale, VARSEEK scale, Dutch restrained eating scale, health taste attitude scale, etc. have been developed and effectively used to predict consumer liking and behaviors. Since the globalization of Korean food is currently one of the hottest topics in the Korean food industry, the aim of this study was to identify the tastes and flavors that may represent Korean cuisine. Additionally, an attitudinal scale for Korean taste and flavors was developed, which can then be utilized to predict a consumer's liking of Korean food. In the first stage of the experiment, the representative taste and flavors of Korean cuisine was surveyed by a Korean culinary expert group (n=23) and general consumers (n=62). As a result of these surveys, 4 types of flavors, hot pepper flavor, 'goso' flavor, garlic flavor, and fermented flavor were shown to be the most representative flavors of Korean cuisine. Based on these results, the second stage of the experiment was carried out to develop an attitudinal scale for Korean style flavors. Eleven to 17 questionnaires were developed for each of the 4 types of flavors. The survey consisted of a total of 53 questionnaires and 154 female consumers and 158 male consumers participated in the survey. The data was analyzed by factor analysis. For each type of flavor, the final attitudinal questionnaires were selected based on the following criteria: 1. high absolute factor loading value, 2. carrying clear meaning of the corresponding flavor attitude, and 3. delivering the meaning sufficiently when translated into other language. The final Korean style flavor attitude scale consisted of 7 hot pepper flavor, 6 'goso' flavor, 6 garlic flavor, and 7 fermented flavor questionnaires. In the next step of this study, experiments will be carried out to validate the Korean style flavor attitude scale.

This study investigated the proximate compositions and sensory attributes of fresh and boiled soybean sprouts. The sensory attributes of cooked soybean sprouts (Kongnamulmuchim) were also assessed after boiling and seasoning. Proximate compositions were analyzed from the total sprout, cotyledon and hypocotyl without hair root. Soybean sprouts cultivated with four recommended soybean cultivars (Nokchae bean, Dawon bean, Seonam bean and Pungsannamul bean) in a lab and then used for analysis. Carbohydrate, protein, lipid and ash contents were lower, while moisture was lower, in the cotyledon than in the hypocotyl of fresh soybean sprouts, regardless of the bean type. Each soybean sprout showed different contents of chemical constituents in total sprout, cotyledon, and hypocotyl parts. Sensory attributes such as odor, flavor, and overall acceptability were evaluated. Each panels showed a response on a 9-point rating scale. The acceptability of fresh soybean sprouts was negatively correlated with beany and grassy tastes, but positively correlated with nutty and sweet tastes. The acceptability of boiled soybean sprouts was negatively correlated with beany and grassy flavors, and positively correlated with nutty odor and flavor. In addition, acceptability of cooked soybean sprouts (Kongnamulmuchim) was positively correlated with nutty and sweet flavors. The beany and grassy flavors limited acceptability of fresh soybean sprouts, whereas the prominence of nutty flavor might contribute to acceptance of boiled and cooked soybean sprouts.

To produce the instant marsh calm(Corbicula elatior) soup with abundant taste and flavor. optimum conditions of heating temperature and time for extraction were investigated. Excretion rate in a pre-treatment for excretion of estuary was 82% at 15% salt concentration for 6 hr and 95% at pH 7.5 for 10 hr. The contents of glycogen and amino-nitrogen were the most high levels in the treatments extracted at 9$0^{\circ}C$ for 3 hr, at 10$0^{\circ}C$ for 1.5 hr and at 11$0^{\circ}C$for 1 hr. The contents of total free amino acids in the extracts treated at 9$0^{\circ}C$, 10$0^{\circ}C$ and 11$0^{\circ}C$ were 367.05mg/100g, 472.23 mg/100g and 463.54 mg/100g, respectively and optimal temperature was above 10$0^{\circ}C$. The mineral contents was the most high level for the extract treated at 10$0^{\circ}C$ for 1.5hr. The results of sensory evaluation showed that tastes for the marsh calm extracts had no significant discrimination, while external appearances and flavors for the extract done at 10$0^{\circ}C$ for 1.5 hr were excellent. The extracts at 10$0^{\circ}C$ showed a little dark color and those at 9$0^{\circ}C$ smell a little fish flavor.

In this paper, the differences between Korean and Japanese ways of seasonings are studied. The main results are summarized as follows: (1) Shouyu and Miso which are Japanese equivalents of soy sauce and bean paste of Korean foods are used in variety of different seasonings with some other ingredients while Korean counter parts are used only to add salty tastes. (2) Shouyu and Miso lose their flavors after considerable time of heating, while Korean soy sauce and bean pastes increase their tastes after heating. (3) Mirin adds sweety taste and glaze and Sake makes food soft or hard according to the moment of being added during cooking. (4) In Korean foods soy sauce, bean paste and red pepper paste are on the basis of tastes, Dashi is used in almost every Japanese food. (5) Seasoned vegetables of Korean food are prepared only with spices of green onion, garlic and sesame oil while seasoned fishes or vegetables are mixed with Shoyu or salt and vinegar in Japanese food. (6) In making Zorim, Korean traditional sauces are added from the beginning of heating. But in making Nimono, sugar, salt, vinegar, Shoyu and artificial taste are added in order during heating. (7) In grilling, main food for grilling in Korea is meat, which is prepared with a variety of spices such as soy sauce or/and red pepper pastes, garlic, green onion, sesame oil, sesame powder, pepper and sugar while mainly fishes are grilled with salt, occasionally with Shoyu or Miso in Japanese food. (8) Pan frying fishes are taken with soy sauce with vinegar in Korea but Tepura are eaten with Tentsuyu in Japan.

With tablets and powder, decoction has been a widely-used method of medicine formula. However, for these formulas have unique bitter tastes and flavors of herbal component materials as it is, the compliance of herbal medicine is severly decreased especially for female and younger patients. Consequently, expected treatment effects can't be acquired completely. If loathsome tastes and flavors of decoction were effectively reduced while pharmacological activity were kept intact, the compliance could be promoted Chong-Myung-Tang has been widely prescribed for student patients with memory This study shows that Chong-Myung-Tang+chocolate have no difference from Chong-Myung-Tang in terms of pharmacological activity. Sensory difference with net chocolate was also surved. In order to observe the difference of Chong-Myung-Tang+chocolate and Chong-Myung-Tang, memory impairment was induced by intraventricular injection of $A{\beta}_{25-35}$ peptides on mice and Chong-Myung-Tang and Chong-Myung-Tang+chocolate were administered orally for 14 days. In water maze task, improvement of learning ability during acquisition period and significant increase of memory score during retention period resulted from the treatment of Chong-Myung-Tang and Chong-Myung-Tang+chocolate with respect to the $A{\beta}-injected$ control animals. Furthermore, the $A{\beta}_{25-35}$ toxicity on the hippocampus was assessed with immunohistochemistry (Bax, TUNEL), and differences in antioxidant activity was observed through TBARS and DPPH test. We employed sensory tests using chocolate flavor, herb flavor, and bitter taste & hardness as standards to show sensory differences with net chocolate. In this study, it is demonstrated that Chong-Myung-Tang+chocolate do not disturb the pharmacological activity of Chong-Myung-Tang, and have no sensory difference with net chocolate. Chong-Myung-Tang+chocolate can be used to enhance the compliance remarkably and thought of as an effective, functional formula to maximize expected treatment.

To establish the optimal fermentation periods in the manufacture of mushroom fermentation foods using sugar, changes of quality characteristics of the mushrooms fermentation broth were investigated with changes of enzyme activity and physiological functionality during fermentation. Viscosity, L value (lightness), a value (redness) and b value (yellowness) were significantly decreased after 3 months of fermentation and after that, increased. In sensory evaluation test, unique flavors and tastes of mushrooms in the fermented broth were decreased during fermentation, whereas the other tastes and flavors were gradually increased. Overall acceptability was the highest in the 3 months of fermentation broth. ${\alpha}-Amylase$ activities of the fermented broth were significantly increased to 1 month of fermentation, however invertase and cellulose activities were low or not detected in the fermented broth. Antioxidant activities were the highest in 4 months of fermentation and after that, decreased. Tyrosinase inhibitory activities were high in all samples and they were not changed during fermentation. SOD-like activity was high in the fermentation broth of Flammulina velutipes and it was also not changed during fermentation. In conclusion, optimal fermentation periods in the manufacture of mushroom fermentation foods using sugar was 3 or 4 months.

The purpose of this research was to find the most appropriate process for making yacon leaf tea. We applied both green tea and black tea brewing and fermenting methods for producing yacon leaf tea. This research included consumer test and descriptive analysis of professional trained panel on yacon tea tastes and flavors. Both consumer test and descriptive evaluation preferred yacon tea produced by black tea brewing and fermenting methods because it tasted less bitter and had a sweet, delicate taste. According to orthogonal transformation resulting from varimax rotation, first principal component was positively affected by black tea brewing and fermenting methods, while it was negatively affected by green tea brewing and fermenting methods. As a result, the study concluded black tea brewing and fermenting methods were appropriate for producing yacon leaf tea.
