In order to setup the diet guideline of five grains, five meats, five fruits, and five vegetables for the diseases of five organs, I reviewed the their tastes by comparing "Naekyeong" with "Euhakibmun", "Dongeuibogam". 'Ma(麻)' in "Naekyeong" means not a hemp, a ramie or a jute, but a sesame(胡麻;참깨). 'Maik(麥)' in it means both a barley(大麥;보리) and a wheat(小麥;밀). 'Guak(藿)' in it means bean leaves(콩잎), leaves of a red-bean(팥잎) or brown seaweed(海藻;미역). 'Gyu(葵)' in "Euhakibmun Jangbujobun(臟腑條分)" is a miswritten word for 'Welsh onion' caused by similarity of shape of word. Food of a salty taste according to five elemental arrangement in "Naekyeong" is really salty according to "Euhakibmun" and "Dongeuibogam". But a barley(大麥) and a wheat(小麥) of sour taste are bitter, a chicken of sour taste or hot taste is sweet, nonglutinous millet of sour taste is sweet, an apricot of bitter taste is hot, a sesame seed of sweet taste is sour, a nonglutinous rice of hot taste is sweet, and a horsemeat of hot taste is bitter according to them. There are two ways to recommend the food for diseases of five organs. One way is to promote or control the Qi(氣) of five organs according to "Somun(素問)" and "Euhakibmun Jangbujobun", the other way is to build up the Yin(陰血) of five organs according to "Yungchu(靈樞) five tastes(五味)". The two different ways are not contradictory to each other, but complement on the view point of their substances(體) or actions(用).

To obtain enzyme hydrolyzed vegetable protein (EHVP) with a salty and umami taste, defatted soybean meal was treated with proteases such as Flavourzyme$^{(R)}$ (F), Neutrase$^{(R)}$ (N), Alcalase$^{(R)}$ (A), and Protamex$^{(R)}$ (P) in various reaction orders. The highest soluble solid content of EHVP was 5.60% in enzyme reaction order NAFP although there was no significant difference. Amino type nitrogen was highest in ANFP (102.76 mg%) and APNF (102.85 mg%). In the sensory descriptive analysis, salty taste was highest in PNFA (11.81), followed by NPAF (10.14), FPNA (10.00), APNF (9.80), NAFP (9.76), AFNP (9.57), APFN (9.52), and NPFA (9.50) with no significant difference among treatment. Umami taste was not significantly different among the various enzyme treatments. Bitter aftertaste was highest in AFPN (5.67) and lowest in FAPN (2.38), PNAF (2.62), and NAPF (2.48). In the principle component analysis, EHVPs of PNFA, NAFP, APFN, NPAF, FPNA, NPFA, and APNF showed a strong salty and umami taste. Therefore, the PNFA, NAFP, APFN, NPAF, FPNA, NPFA, and APNF are desirable methods for making EHVP with a salty and umami taste.

This study investigates the preferences Chinese have of Korean Kimchi and improvements for Chinese market adaptation of Kimchi through a survey. The questionnaire was conducted on 298 Chinese(108 males, 190 females) residing in Weihai, Yantai and Qingdao in Shandong province. The questionnaire form was developed and used for self-administration. The collected data were analyzed by SAS package. Among the subjects, 88.9% had experienced eating Kimchi and 58.8% liked Kimchi. The preference of Kimchi was significantly higher among males, workers, persons who had visited Korea, and persons interested in Korea compared to females, university students, persons who hadn't visited Korea, and persons with no interest in Korea. The reasons for liking Kimchi, in order of popularity, were for its 'refreshing taste'(64.9%), 'spicy taste'(57.7%), 'chewy texture'(47.2%), and 'sour taste'(35.1%). The reasons for disliking Kimchi were for its 'smell'(19.6%), 'sour taste'(16.2%), 'salty taste'(14.3%), and 'appearance'(8.7%). Of those surveyed, 97.6% had a positive opinion of Kimchi intake in the future. The intention of future consumption of Kimchi was significantly higher in females than males. The type of Kimchi wanted by Chinese was 'less seasoning'(53.4%), 'less spicy'(46.0%), 'sweeter taste'(39.3%), 'less salty'(37.2%), and 'no fish-like smell'(35.6%). Improvements for increasing Chinese Kimchi consumption were 'development of Kimchi according to Chinese preference'(81.2%), 'improvement of sanitation'(73.5%), 'decrease in the sale price of Kimchi'(72.8%), and 'convenient place for the purchase of Kimchi'(63.8%).

The study was carried out from March to May in 1998 to compare the food habits and food preference of 391 men in Kyung Nam area who were between twenties and sixties. The summarized results are as follow: 1. The 30's were highest(173.8cm) and the 60's were lowest(168.3cm) in their average stature. The 30's were heaviest(68.2Kg) and the 20's were lightest(62.3Kg) in their average weight(P<0.001). Average BMI was highest in the 50's and lowest in the 20's. 2. Average food habit score of the subjects(4.08) was as low as belonging to the poor group and lowest was 20's. 3. The rate of not eating was highest in the breakfast and the subjects ate breakfast more as they were older(P<0.001). The serious problem of food habit was irregular eating time. The subjects ate in the more irregular time as they were younger. 4. 88.9% of the subjects preferred cooked rice and cereals as their main food, kimchi as their side dish and fruit as their eating between meals. 5. We found great differences in the kinds and number of drinkings subjects preferred as their ages(P<0.001). 20's preferred cider and cola. 30's, 40's and 50's preferred coffee and 60's preferred ginseng tea and citron tea. The rate of smoking was higher in 30's and 40's then in 20's and 50's. 6. 72.9% of the 20's and 16.7% of the 60's ate instant food more than 2-3 times a week. They ate Ramen most often because of its convenience. They ate out more as they were younger and preferred Korean food as their eating out menu. 7. The degree of preference in a sweet taste was highest in 20's and lowest in 40's (P<0.01) and the degree in the preference of a sour taste became lower as they were older(P<0.001). Only in the preference of a salty taste, we could find the difference of the BMI level. They showed high degree in the preference of a salty taste as the order of the over-weight group, normal group, under-weight group and fat group. They showed meaningful correlationship between the level of BMI and the degree of preference of a salty taste in 20's and 40's and between the food habit score and the level of BMI in 60's (P<0.05).

The purpose of this study was to investigate the effects of preschool children's taste preferences on their intake of nutrients and the degree of dental caries. The subjects were 126 preschool children (boys 62 and girls 64) in Daegu area. Their taste preferences and food intake were investigated and their teeth were also examined. The energy intake of boys (1550 kcal) were significantly higher than that of girls (1441 kcal). Daily dietary intakes of nutrients-except niacin and vitamin C-were higher than those of RDA. Vitamin B$_1$ intake of the group preferring a salty taste was significantly lower than that of the other group (p<0.05). Vitamin B$_2$ intake of the group preferring a salty taste was significantly higher than that of the other group (p<0.05). Vitamin C intake of the group preferring a hot taste was significantly higher than that of the other group (p<0.05). The group with a preference for sweet had more experiences of dental caries and more decayed teeth than the other group, but which is not significant. The experiences of dental caries were negatively correlated with protein intake (p<0.01). The decayed teeth were negatively correlated with energy and protein intakes (p<0.01). Our data suggested that taste preferences are associated with vitamins intake and the degree of dental caries in preschool children. It means the sweet preference increased the experiences of the dental caries.

In an attempt to figure out the relationship between zinc status and taste acuity of old and young women, dietary zinc intake, urinary zinc excretion, and taste acuity were determined for 118 women. Zinc intake was measured by 2-day food records and food frequency method. Urinary zinc excretion was measured from urine samples collected for twenty four hours. Body fat, lean body mass (LBM), and total body water were measured by bio-impedence. Average dietary zinc intake by food record was 4.15$\pm$1.33mg (=35% if Korean RDA) for the old women and 5.41$\pm$2.76mg (=25% of RDA) for young women. When zinc intake was measured by a frequency method, the average intakes of the old and young women were 3.5$\pm$1.7mg 4.5$\pm$1.9mg, respectively. It appears that dietary zinc intake of young women was significantly higher than that of the old women. Average urinary zinc excretion of the subjects was 0.27$\pm$0.16mg in the elderly and 0.24$\pm$0.13mg in young women, which indicated a marginal zinc status. However, zinc status was not significantly different between old and young women. Correlation analysis indicated that zinc intake and urinary zinc excretion were positively related to BMI and LBM in young women. The old women (m=49) showed significantly higher taste detection thresholds than young subjects (n=47) for both sweet and salty tastes. Recognition thresholds for sodium chloride and sucrose were not significantly different between old and young women. The lower the taste thresholds for salty taste, the higher the average dietary zinc intake. However, taste perception concentration was not related to the urinary zinc excretion level.

This study was designed to investigate dietary life related to sodium of participants in hypertension and diabetes preventive education at the public health center located in Incheon Metropolitan City. Subjects were comprised of 301 adults (males: 102, female: 199) of age 50 years and above. The questionnaire for dietary life and salty taste assessment were performed on the subjects. Data were analyzed using SPSS package (ver. 18.0). According to the result of questionnaire for dietary behavior, 70% of the subjects were in the low salt intake group (p<0.001). In the result of questionnaire for dietary frequency, all ages groups were in the low salt intake group (p<0.01). The data of questionnaire for dietary behavior showed that the subjects of age above 75 years preferred salted seafood, soup, and kimchi (p<0.01). The data of questionnaire for dietary frequency showed that the subjects of age between 65 and 74, least chose fried kimchi, noodle, and soybean paste soup with clams (p<0.05), and the healthy adult groups chose kimchi stew, ssam and ssamjang (p<0.05). The score for dietary behavior in male subjects was higher than female subjects (p<0.01). In particular, the score for dietary frequency was the lowest in the subjects of age between 65 and 74 (p<0.01). The mean value of salty taste assessment in the subjects was 0.41% which is higher than the ideal value of 0.3% (p<0.01). Offering more nutrition education and continuous feedback of healthcare center may be needed to improve the health status of the adults.

BACKGROUND/OBJECTIVES: This study aimed to compare 24-h diet recall (DR) and 24-h urine collection (UC) for estimating sodium and potassium intakes and their ratio (Na/K), identifying factors associated with sodium and potassium intakes and Na/K, and identifying those who were likely to underestimate sodium and potassium intakes by DR. SUBJECTS/METHODS: A total of 640 healthy adults aged 19-69 yrs completed a questionnaire survey, salty taste assessment, anthropometric measurement, two 24-h DRs, and two 24-h UCs. RESULTS: The mean sodium and potassium intakes and Na/K were 3,755 mg/d, 2,737 mg/d, and 1.45 according to DR, and 4,145 mg/d, 2,812 mg/d, and 1.57 according to UC, with percentage differences of -9.4%, -2.7%, and -7.6% in the values between the two methods, respectively. Men, older adults, smokers, obese individuals, those who consumed all the liquid in the soup, and those who were found to be salty in the salty taste assessment consumed significantly more sodium; older adults, the heavy- activity group, and obese individuals consumed more potassium; and men, younger adults, smokers, and obese individuals had a significantly higher Na/K, according to UC. Compared with UC, DR was more likely to underestimate sodium intake in older adults, smokers, obese individuals, those who consumed all the liquid in the soup, and those who consumed eating-out/delivery food at least once a day, and potassium intake in older adults, the heavy-activity group, and obese individuals. CONCLUSIONS: The mean sodium and potassium intakes and Na/K estimated by DR were comparable to those measured by UC. However, the association of sodium and potassium intakes with sociodemographic and health-related factors showed inconsistent results when estimated by DR and UC. Factors influencing the underestimation of sodium intake by DR compared to UC should be further investigated.

The objectives of this study were to determine the consumption pattern and importance of Kimchi in our meals, and the preference of Kimchi. The 77.0% of the housewife respondents were preparing Kimchi at home. The reasons for not making Kimchi were ‘don't have time’(39.4%), ‘don't know how to make Kimchi’(18.2%) and ‘don't eat much’(18.2%). The amounts of daily Kimchi intake of the respondents were ‘less than 50g’(42.3%) or ‘50-100g’(29.8%). They are Kimchi because it was ‘delicious’(48.4%) or ‘habitual’(39.5%). The 70.0% of the respondents answered that Kimchi was important in each meal. The most respondents favored ‘moderate’ in the degree of fermentation(48.1%), hot taste(65.0%) and salty taste(72.4%). As the age of the respondents increased, they favored less sour, less hot and less salty taste. Baechu Kimchi(4.15), Chonggak Kimchi(3.89), Dongchimi(3.85), Kkaktugi(3.74), water Kimchi(3.67) were preferred by the respondents. The 73.97% of the respondents preferred Kimchi Jjigye. The 10- to 19-years old respondents preferred Kimchi Jjigye(52.8%), Kimchi pan cake(24.5%) and fried rice with Kimchi(17.0%).
