  • It was the purpose of this study to determine if the changes in the sense of taste occur with the periods of the menstrual cycle in 14 women aged 20 to 22 years. Results showed that the perceived intensity responses to different suprathreshold salt concentrations and the ad libitum salting level in soybean sprout soup did not differ significantly according to the different periods of the menstrual cycle. But women in the three or five days period previous to menstruation were sensi\ulcornertive at the lower salt concentration of 0.25%, but, on the contrary, were insensitive at the higher concentration of 1.25%, with increasing ad libitum salt preference in soybean sprout soup. Also, they were more or less high in the intensity slopes of perceived saltiness on the linear regression. The data suggests that a physiological mechanism for increasing salt intake may develop during the three or five days right before menstruation.

  • This study was conducted to ivestigate the quality of modeled chinese-cabbage Kimchi. The mutual action of sub-ingredients and optimum mixing conditions were examined by analyses of pH, acidity, content of vitamins, carotenes, number of total microorganism, and Lactobacilli, the activities of softening related to enzymes (polygalacturonase and ${\beta}$-galactosidase), and sensory quality during fermentation. The result about the mutual action of red pepler powder and garlic showed that the pH was decresed as concentration of garlic was higher and that of red peppler powder became lower. Kimchi had unpleasant taste and undesirable odor when the adding ratio of the peper powder and garlic was unbalanced. As the concentration of garlic became higher, the content of vitamin C in Kimchi tissue decreased while that of vitamin C in Kimchi juice increased. The contents of vitamin B1, B2 and carotene increased as the concentration of garlic became lower. The optimum mixing ratio of red pepper powder and garlic evaluated by overall eating quality was 4.66% and 3.45%, respectively. The result about the mutual action of ginger and green onion was that pH became higher as the concentration of ginger was 1.84% and that of green onion was 5.96%. The intensity of fresh taste and odor became stronger as the concentration of ginger increaed to 2.76% and that of green onion decreased to 2.98%. The balance of sour, salty and hot taste became better as the concentration of ginger increased and that of green onion decreased. The optimum mixing condition evaluated by overall eating quality was 2.94% in ginger + 2.78% in green onion. The contents of vitamin B1, B2 and C were high in this condition. The result about the mutual action of leek and salted anchovy juice was that pH became lower as the concentration of leek increased and that of salted anchovy juice decreased. Sour, hot and sweet tastes were good in the condition of leek 12%, salted anchovy juice 4.69%. Palatable, fresh taste and odor became weaker when the one of both sub-ingredients was too much little. The optimum mixing condition evaluated by overall easting quality was 9.76% in leek + 7.32% in salted anchovy juice. The contents of vitamin B1, B2, C and carotene were high in this condition and other sensory qualities were good. The result about the mutual action of salt and sugar was that pH became lower as the concentration of sugar became higher and that of salt became lower. The sweet taste was reduced of hot taste than salty taste. Palatable and fresh tastes were desirable when Kimchi fermented with less salt and more sugar. The optimum mixing condition evaluated by overall eating quality was 3.29% in sugar + 4.80% in salt. The contents of vitamin B1, B1, C and carotene were high in this condition. The result of model Kimchi fermented at 20$^{\circ}C$ was that the number of Lactobacilli in model Kimchi was higher than that of in control Kimchi. The fermentation period was extended under pH 4.0 and the contents of vitamin B1, B1,C and carotene were high through the whole edible period. The activity of polygalacturonase was low, but that of ${\beta}$-galactosidase was high during fermentation.

  • This study attempts to develop a mass production product standardized by the application of high pressure extraction cooking(HPEC) in order to suggest a desirable direction for the development of salt contained standardized chicken stock. In our experiment on chicken stock with varying its salt content, the total free amino acid content was highest in S3, which contained 0.3% of salt In addition, when the total content of free amino acid was divided into the contents of essential amino acid, palatable amino acid, and other types of amino acid, they showed the same distribution as the total content of free amino acid. In addition, the total content of palatable amino acid was highest among the specimens. In the results of investigating the palatability of chicken stock according to salt content, saltiness increased with the increase of the salt content, but no significant difference was observed in preference for saltiness. It is believed to have come from the difference in the sensory evaluators' preference for saltiness, and it shows that the salt content has an effect on sweet taste, delicate taste, fishy smell, and color. In particular, specimen 83, which contained 0.3% of salt, showed the highest content of palatable amino acid, and the highest level of delicate taste in sensory tests, suggesting the correlation between palatable amino acid and delicate taste.

  • The effects of salting degree of cabbage on the chemical, microbiological, textural changes and taste of Korean whole cabbage Kimchi fermented at $21^{\circ}C$ was studied. Low salted Kimchi (1.8% NaCl, soaking for 2 hr. in 20% brine) was showed higher total acdity than high salted Kimchi II(3.1% NaCl, Soaking For 8 hr in 20% brine) and III(2.9% NaCl, no soaking in 20% brine). The changes in growth of lactic acid bacteria was relevant to the salt content of whole cabbage Kimchi. Kimchi I was showed higher growth rate of Lactic acid bacteria and slower death rate constant of Lactic acid bacteria than that of Kimchi II and III. In palatability test, salty taste of Kimchi II, III was more salty than that of Kimchi I ($p{\leqq}0.01$) and total evaluation of Kimchi I, II was more palatable than Kimchi III ($p{\leqq}0.05$) at 3rd's day (optimum taste). Cutting force by Rheometer was well correlated with the salt content of Kimchi.

  • High sodium intake is one of the risk factors for the development of hypertension. According to 2007 Korean National Health and Nutrition Examination Survey, sodium intake of Korean was three times higher than adequate intake (1.5 g/day) recommended by Korean Dietary Reference Intakes. High sodium intake is related to high threshold and preference of salty taste. And zinc status is known to affect taste acuity. The hypothesis of this study is that zinc status is associated with salty taste acuity, preference, sodium intake and blood pressure. The subjects included in this study were 50 men and 41 women aged 20-29 y who did not smoke and not take supplements or medications regularly. Dietary intake data for 3 days were collected by 24-h recall for 1 day and dietary record for 2-days. Salty taste acuity and preference were determined by sensory test. Fasting serum concentration of zinc, height, weight, body composition and blood pressure data were collected. Salt taste preference in high zinc intake group ($\geq$ estimated average requirement, EAR; men-8.1 mg/day, women-7 mg/day) was higher than that in low zinc intake group (< EAR). Salty taste preference was inversely correlated with serum zinc concentration in people with low concentration of serum zinc (${\leqq}\;81\;{\mu}g/dL$)(r = -0.3520, p < 0.05). Diastolic blood pressure was higher in high sodium intake group than in low sodium intake group (p < 0.05), positively correlated with salty taste preference (r = 0.3866, p < 0.05) in subjects with daily zinc intake below the EAR. We conclude that low zinc status may be related to high salty taste preference and high blood pressure in Korean young adults.

  • Sodium is a component of salt and naturally taken in the process of taking in table salt. For food processing, salt is very important. In general, salt adds flavor and taste including a salty taste and rheologically, it plays an important role in forming tissues. Also, it helps in improving preservability of food by controling growth of microorganisms. But excessive intake of salt has been blamed for outbreak of high blood pressure, heart disease, stroke, osteoporosis, kidney stone, stomach cancer and others. For this reason, there are active efforts to reduce sodium of processed foods all around the world. In Korea, a guideline for sodium reduction in 27 items and 44 kinds of foods including confectionery was suggested as part of the 'processed food sodium reduction guideline development project', which has been conducted since 2012.

  • This study applied high-pressure extraction cooking, which has been proven superior in processibility and stock extraction, for the preparation of stock, which is widely used as a basic material of dishes, and examined the physicochemical and sensory properties of the extracted stock by adding salt. We observed changes in the chromaticity of brown stock according to salt content, and pH decreased with increased the salt content, suggesting that stock was acidified. Regarding the mineral content, Na was the highest, followed by K and P. Regarding total free amino acid content, the content of essential amino acids, enhancing free amino acids, and other amino acids also showed the highest level in S2, which contented 0.3% salt. In the sensory test, saltiness grew stronger with an increase in salt content, and overall palatability was highest in S2. Regarding ranking, preference was highest for S2. Utilize to data that study finding of above is actual in development for mass production of brown stock product licensed cooks' traditional mesh dipper technology quality that make mass production direction that change and normalizes product that can keep excellent taste and improve conservative property develop. Culture formation and our country foodservice industry development that reduce damage of informed people ashes through development of brown stock product that is changed in large quantity, and improve quality of food more positively contributing to reappear diversification of menu, systematization and taste of specialty store as well as can contribute in rationalization of informed people ashes purchase, personnel expense (labor power) curtailment, waste decrease etc. but is developed still more being utilized.

  • 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.

  • This study evaluated the sensory characteristics of sauerkraut prepared by adding 0.5, 1.0, 1.5, 2.0, and 2.5% (w/w) sea salt to cabbage. The quantitative descriptive analysis (QDA) and acceptance test of sauerkraut were determined for each salt concentration, and the principal component analysis (PCA) and partial least square regression (PLSR) analysis were performed to confirm the correlation between each factor. Results of the QDA determined 14 descriptive terms; furthermore, brightness and yellowness of appearance and the sour, salty, and bitter flavors differed significantly according to the salt concentration. Results from the PCA explained 22.56% PC1 and 65.34% PC2 of the total variation obtained. Sauerkraut prepared using 0.5, 1.0, and 1.5% sea salt had high brightness, moistness, sour odor, green odor, sour flavor, carbonation, hardness, chewiness, and crispness, whereas sauerkraut prepared with 2.0 and 2.5% sea salt had high yellowness, glossiness, salty flavor, sweet flavor, and bitter flavor. Hierarchical cluster analysis classified the products into two clusters: sauerkraut of 0.5, 1.0, and 1.5%, and sauerkraut of 2.0 and 2.5%. Results of PLSR determined that sauerkraut of 1.0 and 1.5% were the closest to texture, taste, and overall acceptance. We, therefore, conclude that sauerkrauts prepared using 1.0 and 1.5% sea salt have excellent characteristics in appearance, taste, and texture.
