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.

High blood pressure is an important determinant of the incidence of coronary heart disease, stroke, congestive heart failure, renal failure, and peripheral vascular disease. Recommendations for control of high blood pressure emphasize lifestyle modification, including weight control, reduced sodium intake, increased physical activity. Subjects who were normotensive (n=19, $47.2\pm9.0$ y, BP l16/81 mmHg) ,treatment hypertensive (n=33, $54.2\pm6.9$ y, BP 132/85 mmHg) and non-treatment hypertensive (n=14, $50.1\pm11.0$ y, 149/94 mmHg) recruited. Anthropometric assessment (height weight waist circumference, hip circumference, fat$\%$, fat mass, and lean body mass) and dietary assessments (using 3-days food records, daily nutrient intakes were inuysed by CAN PRO 2.0 were carried out. Blood and 24-hour urine were collected). Test of recognition for salt taste threshold were performed. In non-treatment hypertensive male subjects, weight, $\%$IBW, BMI, and waist circumference were significantly higher than those of normotensive and treatment hypertensive subjects (p<0.05) .Food habits were not significantly different among the three groups. Intakes of vitamin A, vitamin B,, and vitamin B, were significantly higher in normotensive group (p<0.05). Intakes of sodium and salt taste recognition threshold were the highest in normotensive group and the lowest in treatment hypertensive group (p<0.05). Blood levels of lipids and minerals were not significantly different among the three groups. Urinary calcium level of normotensive group were significantly higher than that of treatment hypertensive and non-treatment hypertensive groups (p<0.05). These results indicate that continuous management of hypertension by drug and non-drug treatment affects salt taste recognition threshold and reduced the consumption of sodium. However, dietary sodium intake exceed recommended sodium intake to prevent and treat hypertension. It is necessary to develop the lifestyle modification program that may have beneficial effects on hypertension treatment.

Sik-hae is a traditional and well-liked salt-fermented seafood with a low salt concentration in Korea. However, it is challenging to find data on market degradation. This study was conducted to investigate sensual characteristics, such as taste, odor and color, of 10 types of commercial Sik-haes [flounder (5 type), Alaska pollock (2 type), black edged sculpin, anchovy, and sandfish] as basic data for developing new products. The salinities of the commercial Sik-haes were significantly difference in the range of 3.0-6.7%. The pH and total acidity of 10 types of commercial Sik-haes were 4.45-5.24 and 0.84-1.46 g/100 g, respectively. The amino acid nitrogen and free amino acid contents, and total taste value were 72.0-333.0 mg/100 g, 425.6-1,726.4 mg/100 g and 17.0-115.9, respectively. According to the taste value, the major taste-related amino acids were aspartic acid and glutamic acid. Volatile basic nitrogen content and Hunter redness value of commercial Sik-haes were 24.5-80.9 mg/100 g and 10.9-28.5, respectively. However, food-grade additives, such as citric acid and monosodium, are occasionally used in commercial Sik-haes to achieve a lower pH or enhance flavor and aroma.

This study was performed to investigate factors affecting sensitivity and preference for salty tastes of Korean adult females. Sensitivity and preference for salty tastes were determined as detection threshold concentration of NaCl solution and the optimally-preferred NaCl concentration of the bean sprout soup, respectively. A self-administered questionnaire was used to obtain the information regarding general characteristics, self diagnosis of stress, health-related lifestyle practices, dietary habits and food preferences. Dietary intake using 24-hours recall and blood pressure were measured. Salty taste detection thresholds and optimally-preferred NaCl concentrations were 0.0197% and 0.357%, respectively. There was a significant positive correlation between the optimally-preferred salt concentration and age, despite no significant correlation between either sensitivity or preference for salty taste and sodium intake, which was 3,605mg/day. Those who had bread or cereal with milk as breakfast instead of a traditional Korean meal and those who preferred jjigae to soup had significantly higher NaCl preferences for bean sprout soup. Going to bed after midnight and skipping meals (${\geq}3/week$) decreased salty taste sensitivity without reaching statistical significance. Self awareness of one's own health, recent weight changes, family history of hypertension, sleep quality, getting-up time, rate of eating and other food preferences did not affect either perception. Stress level, TV watching, BMI and sodium intake did not have significant correlation to sensitivity or preference. Further research including a large number of well-controlled subjects and more accurate measurement of sodium intake should be directed to find other factors affecting salt preference and sensitivity in order to decrease Na intake and related diseases.
