The purpose of the study was to investigate the influence of salt (NaCl) recognition threshold and pleasant salt concentrations of Korean rural elderly subjects on preference of salty food as well as food group consumption patterns. The subjects were 213 elderly people (male 71 and female 142) over 65 and under 90 yr of age from Sunchang area. The higher values were found with male subjects in the areas of basic taste recognition threshold and pleasant concentration level of salt. The taste sensitivity scores of male subjects did not decrease with the increasing age, but female subjects exhibited a significant decrease with the age. The major determinant factor of salt preference of the elderly subjects in this study appeared to be personal pleasant concentration of salt rather than salt recognition threshold level and this trend was more evident in males than in females. The subject group of lower salt pleasant concentration i.e. consuming less salt showed the higher number of fruit and fruit juice intakes per week, and higher MNA (define this) scores were implying that they display more desirable nutritional status. Therefore, nutritional education focused on not only a variety of food consumption but also lowering pleasant salt concentration levels is advised to improve the quality of nutrition in the elderly.

The purpose of this study was to develop a nutrition education program for dietary salt reduction using various nutrition education materials. The effect of a 5-week nutrition education program on salty taste assessment, nutrition knowledge, salt attitude for a high-salt diet, salt content in food, and individual satisfaction with the salt concentration of meals during the education period was evaluated. Nutrition education materials included two animations, a pamphlet, panels, and a website, as well as other training resources. Subjects participating in this study were 335 employees (164 male, 171 female) at 15 foodservice operations in Daegu. Preference for higher levels of salty taste and food containing higher amounts of salt were lowered. Knowledge regarding the necessity for dietary salt reduction was higher (p < 0.001) than before nutrition education, and salt content in a meal was reduced. As the program progressed, average salt concentrations of soups were significantly lowered (p < 0.05), and there was greater satisfaction with the lower concentration (p < 0.001). This was a positive indication of the program's success. In addition, it was found that subjects who participated in the program several times have changed their preference to lower levels of salty taste and have increased their nutrition knowledge (p < 0.05, p < 0.001). Thus, the positive effect of this 5-week nutrition education program developed for, and applied to, foodservice employees, concerning dietary salt reduction was confirmed.

College women of 136 in Kyoung-Buk province were studied in order to investigate the quantity of Na intake and preference for salty taste in diet. Also the relation of family's history on hypertention and their Na intake and preference for salty taste were studied. Three type of meal with 9g NaCl, 12g NaCl, 15g NaCl and four type of beef soup with 0.2% NaCl, 0.4% NaCl, 0.6% NaCl, 0.8% NaCl were prepared. The computating value of Na according to the food composition table and the amount of Na by chemical analysis were almost equal. The meal with 12g NaCl was favored 58.8% of the subjects, hence the amount of Na intake per day was thought 13g roughly.50.7% of subjects prefered of beef soup with 0.6% NaCl and those who thought that they eat salty had tendency to like food with high amount of salt. 73 subjects(53.7%) had family's history on hypertention, then 38 subjects (52.9%) among them liked beef soup with 0.4% NaCl 63 subjects(46.3%) didn't have family's history on hypertention, then 44 subjects among thorn liked beef soup with 0.6% NaCl. The subjects with family's history on hypertention liked more salty taste than the subjects with no family.s history on hypertention.

This paper is an effort to describe dietary behaviors to keep them healthy among adults. A probability sample was drawn from residents aged between 15 and 60 living in Ulsan City area through a multi-staged cluster sampling method. The data collected by face-to-face interview includes 1,232 respondents. Both univariate and bivariate analyses were employed to describe the dietary behaviors. The dietary behaviors in this study includes preference of taking fat-part of meat, fried food, salty food, hot-taste food, drinking coffee and milk, and taking supplementary medicine. About half of the respondents reported to take fat removed when eating meat, and more than 68% of them preferred not to take any kinds of fried food. With respect to preference of salty and hot-taste food, 39.6% of the respondents take medium-salty and 39.4% do hot-taste food. A third of the respondents drink two-four cups of coffee a day. Those who reported not to drink milk at all were prevalent(37.4% of the respondents) than expected. However, less than 20% of the respondents reported to have any kinds of supplementary health food in a year. These dietary behaviors were examined by sociodemographic characteristics for bivariate analyses.

Objectives: The purpose of this study was to compare and analyze the results of salty taste assessment, dietary attitudes, and dietary behaviors among adult and senior women by region and by age. The results generated from this was expected to provide fundamental data for implementing a nationwide salt reduction education program. Methods: The salty taste assessment tool was applied to 4,064 subjects from 15 areas in Korea. Also, a survey of dietary attitude and dietary behavior related to salt intake was conducted for all subjects participated in this study. Results: The salty taste assessment scores by region and by age were the lowest in capital (p < 0.01) and was highest among the 70+ year age group (p < 0.01). The dietary attitude scores and dietary behavior scores showed that Gyeongsang was the highest (p < 0.001) and the capital was the lowest. The dietary attitude scores were highest at 20&30's followed by 40's and 70's group (p < 0.001). Dietary behavior scores showed that 20's~30's and 40's groups were higher than the other age groups (p < 0.001). The score of 'I like kimchi' was $3.46{\pm}0.88$, which was the highest among 10 dietary behavior questions. The score of 'I eat a lot of kimchi' was $3.30{\pm}0.90$, which was the highest among 10 dietary behavior questions related to salt intake. The scores of salty taste assessment had significant positive correlations between the scores of dietary attitude (p < 0.001), dietary behavior (p < 0.001) and self-awareness (p < 0.001). Conclusions: Based on the results of salty taste assessment, we observed a tendency that older people and regions except the capital had higher preference for salty taste. Our results suggested the necessity for a nationwide salty reduction education program tailored for regions and for different age groups.

This study was performed to investigate the change in taste perception during aging and its effects on dietary intake in Korean elderly. The subjects were female aged 65 through 90 in the Anyang area, and college women were included as a comparison group . Dietary intake of the elderly(n=155) and young subjects (n=38) was measured by a 3 day diet record. The taste threshold and 'just right' concentrations(JRC) for sweet and salty tastes were assessed by sensory evaluation . Sucrose solution (0.0.,0.4,0.6,0.8,1.0, 1.2%) and salt solution(0, 0.02, 0.03,0.06,0.09,0.12,0.15%) were used to establish thresholds. for JRC assessment, four suprathreshold sucrose concentrations of 5, 8, 11 and 14% in orange-pineapple flavored juice and salt concentrations of 0.20, 0.34, 0.50and 0.75% in beef stock were prepared. Mean intakes of energy, protein , vitamin A, thiamin , riboflavin, niacin ,calcium and iron of the elderly were below the Korean Recommended Dietary allowances. The elderly showed higher taste thresholds than young subjects of both sweet and salty tastes consumed less calories. Needs to bespecified. The older subjects having high threshold or JRCs for sweet and salty tastes consumed fewer calories from protein and fat. Pearson correlation coefficients was between JRC for sweet and salty tastes 0.54(p<0.01). The correlation coefficients between tastes threshold and nutrient intakes were very low for both age groups. Unlike the college women, in the elderly the JRC of sweet taste of the orange-pineapple juice were negatively correlated with intakes of energy, protein, fats, thiamin , riboflavin , niacin ,vitamin C , iron and consumption of meat and egg food groups (p<0.01). In summation age-related alterations in sweet and salty taste perception were observed in the elderly and dietary intakes of the elderly see to be influenced by these taste perception changes.

This study developed eel teriyaki sauce and suggests conditions for its commercialization. Consumer preference tests were carried out with Korean (n=50) and Japanese (n=50) consumers. Grilled eel samples were made by teriyaki sauce with addition of Bokbunja juice, powder, concentrates. The preference tests were itemized for color, flavor, taste, salty taste, softness and overall-preference of grilled eel. Korean and Japanese consumers preferred flavor and taste, and the degree of overall preference was rated higher at 60% for Bokbunja juice, 20% for Bokbunja powder, and 40% for Bokbunja concentrate. Japanese consumers also preferred its color as well. The items of softness and overall-preference had good ratings.

This study investigated the effect of salt preference on dietary habits and the body composition of university students. The subjects were divided into two groups: 85 students who dislike salt (salt-dislike (SD) group) and 104 students who like salt (salt-like (SL) group). We found that the SL group showed a higher preference for sweet, sour, spicy, and bitter flavors compared to the SD group. There was no significant difference in the frequency of eating breakfast according to the salt taste preference. The meal speed of the SL group was significantly higher than the SD group (p<0.01) and the body mass index of the SL group ($22.59kg/m^2$) was higher than SD group ($21.04kg/m^2$). The fat mass of the SL group (15.30 kg) was higher than the SD group (12.80 kg) (p<0.01). Salt preference and snack intake frequency had a significant and positive correlation with fat mass. The frequency of eating breakfast, and meal speed also showed a significant and positive correlation with subcutaneous fat. In conclusion, the SL group eats relatively more, speedily and frequently intakes snacks and carbonated drinks, likely resulting in higher body and subcutaneous fat. These results suggest salt preference is related to food choice, influences unreasonable eating habits, and possibly changes body composition. Taste preferences should therefore be considered for dietary consulting and nutritional education.

The literature suggested that a small reduction in overall blood pressure can have a large effect on overall prevalence of hypertension, and therefore, the affect of taste preferences of the population on salt intake should be considered for long-term blood pressure intervention programs. The purpose of this study is to investigate the influence of salt taste preference and salt taste sensitivity on salt intake behavior as risk factors for high blood pressure. We collected information on blood pressure, diet and lifestyle behaviors, salt taste preference and salt taste sensitivity from 540 respondents from Suseo-dong, Seoul. Salt taste sensitivity was assessed by administering a 1% NaCl solution to the subject's tongue and measuring the perceived intensity on 10 level scale. Salt intake behavior was classified into 3 categories: frequency of high-sodium foods, practice of salt-reducing behavior and frequency of vegetable and fruit intake. Salt taste preference showed a significant relation to the subjects' blood pressure, i.e. subjects with a higher salt preference had higher blood pressure. Salt taste sensitivity did not show a significant relation to blood pressure. However, there was a positive correlation between salt taste preference and salt taste sensitivity. Among the 3 indicators used to measure salt intake behavior, the practice of salt-reducing behavior remained significantly correlated to blood pressure. Moreover, salt-reducing behavior and salt taste preference showed a significant correlation, i.e. people who do not like salty foods tend to practice more salt-reducing behavior, leading to reduced levels in blood pressure. In a population, a small reduction in overall blood pressure can have large effects in overall prevalence of hypertension, in contrast to clinical studies where achievement of an individual's normal blood pressure is emphasized. Therefore, taste preference of the population should be considered for long-term blood pressure intervention programs.

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%).
