  • The aim of this study was to develop a standardized recipe for black sesame gruel that has been preferred for generations as a nutritional food. The method focused on optimizing the mixing ratio of the components to improve the quality of the black sesame gruels that modem consumers would like. The results are summarized as follows: The more black sesame added to the gruel, the lower its brightness was, but the redness and yellowness was higher. The amount of black sesame made a significant difference in the viscosity, color, nutty taste, bitterness, appearance and overall preference. It was highest in the overall preference when the amount of black sesame was added 33g(40% of rice weight basis). Different types of rice were added to the black sesame gruel, and it was observed that the color value of the gruel was high in its brightness, redness and yellowness when 50g(60%) of glutinous rice was added to it. The black sesame gruel was most preferred when 50g of non-glutinous rice was added. The redness value was high when 15g(18%) of non-glutinous rice flour was added. The yellowness value was high when 25g(30%) of non-glutinous rice flour was added. This observation showed significant differences in the viscosity, color, nutty taste, bitterness, appearance and overall preference. In particular, the black sesame gruel was most preferred when 50g of non-glutinous rice flour was added. The addition of 7g(9%) of salt to the black sesame gruel showed the highest brightness. The redness and yellowness was the highest when 5g(6%) of salt was added. This observation showed a significant difference in the viscosity, color, nutty taste, bitterness, appearance and overall preference. The highest preference was observed when 2.5g(3%) of salt was added. Adding more materials increased the viscosity of the black sesame gruel. With increasing temperature, the viscosity became lower, and vice versa. The intensity of sweetness and spreadability was found to be proportional to the amount of additive material. In conclusion, the optimum recipe for black sesame gruels was obtained 33g(40%) of black sesame, 50g(60%) of glutinous rice (flour), 2.5g of salt, and 500$m\ell$ of water.

  • The purpose of this study was to investigate self-assessed preferences for saltiness as well as salt-related dietary behaviors of university students in Gyeongsangbuk-do. Data were collected from subjects, including 175 male and 225 female university students. This survey was conducted using self-boarding questionnaires. Exactly 29.5% of all students answered 'salty' for their self-assessed preference of saltiness, and 42.5% indicated 'salty' for their assessed saltiness of university foodservice operations. Salt-related dietary behavior scores were significantly different among monthly spending money (P<0.01), self-assessed preference of saltiness (P<0.001), frequency of using university foodservice operations (P<0.001), and assessed saltiness of university foodservice operations (P<0.001). Among the 15 items of salt-related dietary behaviors, 4 items scored over 3.00/5.00, including frequent eating-out or consumption of delivered foods, kimchi, soy paste soup or other broth soups, and ramyon (instant noodle). Males revealed higher preferences for ham or sausage (P<0.05), table salt (P<0.01), broths (P<0.01), and complete consumption of soups and stews (P<0.01), whereas females showed greater preferences for eating-out or delivered foods (P<0.01). Overweight students showed higher preferences for all broths and complete consumption of soups and stews (P<0.01).

  • In order to study low salinity Oiji (cucumber pickled in salt) with a reduced content of sodium, which was accomplished by replacing the salt in this saliferous food, we produced Oiji using sea tangle and, then performed physicochemical and sensory evaluations. It was found that the moisture content of Oiji was decreased with increasing the amount of added sea tangle. The pH and acidity were significantly different between the samples made with sea tangle, and the pH and acidity showed no consistent tendency according to the amount of sea tangle powder added. The salinity of Oiji was the highest in the control Oiji (2.92%), and the higher the amount of sea tangle added, the lower was the salinity in the Oiji with the salt replaced by sea tangle (2.78 to 2.89%). The sodium content of Oiji was also the highest in the control Oiji (591.65 mg/100 g) and significantly decreased with the increasing addition of sea tangle (560.43~366.71 mg/100 g). The color value of Oiji showed a significant difference between the samples, with no consistent tendency according to the amount of added sea tangle powder. The hardness of Oiji was significantly greater in the Oiji with the salt replaced by 40% of sea tangle, with greater hardness noted as the amount of added sea tangle powder increased (217.70 g). As a result of the acceptance test of Oiji, there were significant differences between the samples in overall acceptance, appearance, and taste, showing that the Oiji with salt replaced by 30% of sea tangle was significantly highest in overall acceptance and taste. The attribute difference test showed a significant difference only for the brown color, while no significant differences were found between the samples for off-flavor, bitter taste, fermented taste, salty taste, sour taste, hardness and crispness. The above results demonstrated that when sea tangle was substituted for 30 to 40% of the salt content, the Oiji with a low content of sodium and low salinity can be produced with a high level of taste and overall preference. Therefore, this study firmly demonstrated that 30 to 40% of the salt can be replaced by sea tangle as a substitute in order to produce Oiji that has low salinity, a low sodium content.

  • This study was intended to develop traditional Korean soup recipe which can be used for food service and meet consumers' taste with a focus on clear soup such as clear radish soup, sea mustard soup, dried pollack soup, croaker soup, and backbone soup. The developed sample(S1) showed the highest level of overall preference among consumers. There were significant differences in sensory characteristics of the samples especially between S1 and others. The sensory characteristics of each soup showed a slight difference depending on the kind of soup, however, all items had an effect on overall preference. One of the standardized recipe to make broth was presented as follows: The ingredients for broth consists of the shank or brisket of beef(100 g), water(10 cup), spring onion(20 g), onion(30 g), garlic(10 g), salt(1 teaspoonful), and black pepper power(1/10 teaspoonful). 1) The meat part of shank or brisket is prepared. 2) The unfrozen meat is immersed in cold water for 20 min, whereby blood is extracted from the meat. 3) 10 cups of water are poured into the pan and boiled enough. 4) After water has boiled enough, the lump of meat with blood extracted is cut into 2 or 3 pieces and is boiled in the boiling water by high-intensity heat with the pan lid uncovered, and dirty foam is scooped out while boiling. 5) If the broth begins to be extracted, the intensity of heat is lowered for boiling for one hour or so, and then again boiled for 30 min with spring onion, garlic, onion and the like. If the broth is extracted enough, spring onion, garlic, onion, and others are removed from the pan. the broth is seasoned with salt and black pepper powder, and foam is removed by using fine mesh sieve or gauze. Then, 6 cups of clear broth is obtained finally.

  • The aim of this research is to develop recipe of kimchi beverage made of sun-dried salt. A distinction between this recipe with existing ones is the Korean traditional ingredient, sun-dried salt. The variety and amount of recruitment on the beverage was established after its characteristics were investigated by sensory tests. Preference of sweetening agent for the beverage was oligosaccharide > honey > sugar powder > sugar > aspartame > pear juice. While sensory evaluation was conducted on color, flavor and overall acceptance, the overall acceptance scores are as following; 6.24 for watery radish kimchi, 6.00 for white kimchi and 5.76 for Korean cabbage kimchi. Among other beverages, watery radish kimchi beverage was preferred. Amount of kimchi for the beverage was most suitable at 10 % of the contents. It was the same with all the other beverages. When the products were stored in normal temperature, the evaluation scores dropped for all sensory items as time passed.

  • Purpose: We recruited 118 women in their early 20's to examine the relationship between sodium intake and salty taste thresholds and preference. We also examined the association of salty taste preference with sodium-related dietary behaviors and major dishes contributing to sodium intake. Methods: Daily sodium intake was estimated using a 127-item dish-frequency questionnaire. Salty taste thresholds and preference were measured using rating scales using water solution of NaCl and a self-administered questionnaire based on a Likert scale, respectively. Results: Salty taste preference showed positive correlation with daily sodium intake and sodium intake-increasing behaviors, and inverse association with sodium intake-decreasing behaviors, including salt and soy sauce use at the table, the frequency of eating out and home delivery of foods, broth consumption of soup, stew or noodle soup, the use of ready-to-serve or processed foods, fresh vegetable intake, and the accommodating attitude toward bland food. Intake of sodium-contributing dishes, including ramen, spicy soft-tofu stew, radish kimchi, and dishes containing kimchi, also showed positive association with salty taste preference. Unexpectedly, detection and recognition thresholds of salty taste showed no association with salty taste preference, sodium intake, and sodium-related dietary behaviors. Conclusion: These findings suggest that salty taste preference could reflect sodium intake of individuals rather than thresholds of saltiness, and may be used as a simple and effective proxy for usual sodium intake.

  • This study focuses on the qualitative characteristics of mackerel marinated with herb extracts. By differentiating the amounts of garlic, ginger and basil, the optimal amount of each ingredient to he added has been found. According to the result of the experiment, the highest level of preference has been shown for the combination of 3% of garlic, 3% of ginger and 2% of basil, generating the optimal amounts to be added. Since the pH change shown by the mackerel marinated by adding the optimal combination of 3% of garlic, 3% of ginger and 2% of basil is included in the range of pH 6.2-6.4, which is the initial point of decomposition for red-fleshed fish, it can be considered to be appropriate for the qualitative characteristics of the product. According to the differences test, GA3 bas shown the lowest level of strength, making it soft. Also, GA3 has shown the highest level of elasticity together with the characteristic of being moist. As a result, it can be said that garlic is better than ginger and basil. According to the preference test, GA3 has shown the highest level of preference in terms of appearance, flavor, texture, taste and overall preference. By considering the above results of the experiment, GA3 (3% of garlic) can be regarded as the optimal amount to be added.

  • This study aimed to examine consumers' interest, preference, and consumption frequency of Kimchi in elementary school students in the fifth grade and their mothers living in Changwon city. In a comparison of eating habits, students exhibited better eating habits than their mothers (P<0.01). Though the mothers' levels, were higher than those of the students in the category of 'eat foods with a bit of salt usually', the students' levels were higher in the rest of the eating habit categories. The categories of 'like Kimchi', 'spicy taste', and 'appropriately spicy taste' got high levels. Among several kinds of Kimchi, both students and mothers preferred 'cabbage Kimchi' the most. Among various Kimchi foods, preferences for 'Kimchi pancake', 'fried rice with Kimchi', and 'tuna Kimchi soup', were highest in that order. The preferences differed between students and mothers in each category; mothers' preferences were significantly higher than those of students. However, in the rest of categories, except 'boiled kimchi and fish' and 'Kimchi and stir-fried spicy pork', students' preferences were higher than mothers' ones. Compared to their preferences, students' consumption frequencies were significantly higher than mothers' ones (P<0.01). There were positive correlations among students' eating habits, awareness of Kimchi, consumption frequency, and preference. For mothers, there were positive correlations not only between eating habits and awareness, but also between awareness and preference.

  • The relationship between sodium intake and stomach cancer risk has been studied much in Japan but a great portions still remain controversial. There has been few studies on relationship between sodium intake and stomach cancer in Korea. The goal of this nested case-control study is to investigate the association between sodium intake and stomach cancer risk in a rural county of Korea We estimated sodium intake indirectly by the threshold of salt-water taste of patients. This study was based on both of the data from 'Kangwha Cohort Study' which had been conducted from March 1985 and 'Kangwha Community Cancer Registry' which had been launched on July in 1982 by the College of Medicine, Department of Preventive Medicine. Yonsei University. A total of 145 patients who developed stomach cancer in Kangwha County were initially recruited as the case group. We tried to get two community-controls per stomach cancer case by matching age and gender. Finally we got information from 90 cases and 146 controls about the threshold of the salt taste and preference of salty food and so on. Some 79% of the information about ease group came from proxy respondents and 56% among controls. Risk ratios of developing stomach cancer adjusted for smoking, body mass index and self-stated health level were estimated. No statistically significant association between the threshold of salt taste and stomach cancer risk found in this study. We recommend some further studies utilizing urinary salt excretion, diet record method for better estimating of salt intake with a paticular emphasis on interaction effect between salty and spicy food in hospital-based case-control study designs.

  • This research was conducted to obtain the fundamental data on salt injury and different responses among cultivars in winter barley (Hordeum vulgare L.). Salts did not affect yield components including number of panicles, stem length, grain number per ear and grain yield while reduced stem dry weight and thousand seed weight significantly with increasing concentrations of salt from 60 to 180 mM. NaCl had less injury effect on barley straw dry weight and thousand seed weight than did $MgSO_4$. Chlorophyll content and relative turgidity in flag leaf were reduced when treated with both salts, while free proline in the salt-treated leaf was increased. Content of proline in salt-treated barley was about 10 folds compared to the control. Based on yield components and physiological traits of flag leaf, the tolerance to salt injury was the greatest in Baegdong, followed by Dongbori#1, Mogpo#55, and Gangbori. The results suggested that salt- stressed barley at reproductive stage had higher free proline content, and that special management in this stage must be considered because salt stress at heading stage affect flag leaf growth as well as yield components Harmfully.
