This study was attempted to standardize preparation methods of Korean foods; Chigae (Stew) such as Deonjang chigae (soybean stew) and Kimchi chigae (Kimchi stew). We followed cooking methods by using cookbooks, food service operation recipes, materials distributed by commercial food restaurants from their own experimental kitchens, and home recipes. Before this recipes were standardized, we thoroughly analyzed and modified them. The total yield and portions were determined together with material weights and procedures. And we evaluated food made by standardized recipes for acceptability, by taste panels from Sookmyung Women＇s University. It concluded that yield volune for doenjang chigae and kimchi chigae after cooking for 10 persons was 3 kg, optimum service temperature was 7$0^{\circ}C$, preparation time was 50 minutes, service volumes by one person was 300 g. This presentantion for the above on food materials and material weights, preparation methods as well as cautions and references are attached in this research paper.

Sodium is a major component that maintains homeostasis and physiological state in body. It is an essential mineral that the body cannot produce for itself, so it must be supplied from food. On the other hand, overindulgence is one cause of hypertension, stroke, stomach cancer, osteoporosis and kidney disease. The purpose of this study was to monitor sodium content in meals of school foodservice. In this study, 801 samples (main/side dishes) were collected from 8 school foodservice in Busan and Gyeongsangbuk-do, Korea. Samples were classified into 21 food items, which were cooked rices, cooked rice with seasoning, noodles, cooked gruels, soups, stews, tang and chon-gol, stir-fried foods, fried foods, pan-fried foods, hard-boiled foods, roasted foods, steamed foods, seasoned vegetables, preserved foods, kimchis, sauces, fruits, breads and snacks, beverages, and dairy products. The samples were analyzed by AAS (atomic absorption spectrometry) after microwave digestion. The sodium content of sauces (1459 mg/100 g) and preserved foods (1165 mg/100 g) was higher than those of other dishes. Aside from them, sodium contents of roasted foods (894 mg/100 g), hard-boiled foods (786 mg/100 g) and kimchis (737 mg/100 g) were relatively higher than the others. Sodium intakes from meals of school foodservice were calculated by multiplying food intakes by sodium contents. The average sodium intakes from one serving of school foodservice were 605 mg for younger boys, 572 mg for younger girls, 774 mg for older boys, 730 mg for older girls in elementary school. Boys in middle school took in 1423 mg Na whereas girls consumed 1063 mg Na in middle school. Results from this study can be useful for establishing database of sodium contents and intake in meals of school foodservice. The database will be helpful for providing information on managing food for children.

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).

The salinity of soups of institutions enrolled at the Center for Children's Foodservice Management was monitored to reduce sodium intake of children by continuously managing salinity of soups provided by children food service. Monitoring of salinity was conducted by a salinity meter (SB-1500H, HM digital) three times in 2016 by patrolling children's institutions for the instruction of public health. The average salinity of soups provided by total children's institution showed a significant decrease in salinity - $1^{st}$ 0.45%, $2^{nd}$ 0.41% and $3^{rd}$ 0.39% - as monitoring was proceeded (p<0.01). When salinity of soups was analyzed according to the type of children's institution, the salinity of national and public institutions showed no significant decrease. In contrast, the salinity of private institutions decreased significantly (p<0.05). Depending on the enrollment of the food service, there was no significant difference in average salinity of soups between large food services, which have over 50 children, and small food services, which have less than 50 children. However, all food services showed a salinity decrease from the $1^{st}$ monitoring to the $3^{rd}$ monitoring. Salinity according to the type of soup showed that salinity of clear soup, miso soup, and stew except beef soup decreased from the $1^{st}$ monitoring to $3^{rd}$ monitoring. However, there was no significant difference in salinity according to the type of soup which can be attributed to a large difference in salinity among the same type of soup. The individual soup showing the biggest difference between maximum and minimum salinity of soup was egg soup (0.62%), potato soup (0.54%), and mushroom soup (0.64%). The present average salinity of soup provided by children's institutions was less than 0.5% which is the recommended standard of the Ministry of Food and Drug Safety. However, the salinity of soups should be managed within a certain range including the minimum salinity regarding the taste education of children.

The objective of this study was to investigate dietary sodium sources at the dish level in 228 university students (71 men, 157 women) in Gyeonggi-do. Daily sodium intake was estimated from a validated 125-dish frequency questionnaire. In men, body mass index, systolic blood pressure, and sodium intake were significantly higher than in women. Men showed higher sodium intake from soups, fish or shellfish dishes, meat dishes, and soybean dishes than women. The dishes that most largely contributed to daily sodium intake were Napa cabbage kimchi and ramen in both men and women. In addition, relatively higher amounts of sodium from ramen were consumed in men, whereas cookies were the 5th highest sodium source in women. In both men and women, the high sodium intake groups consumed more sodium from kimchi, dishes cooked with kimchi, dishes with broth, and salted mackerel than the low sodium intake group. There were significant differences in major dishes contributing to between-person sodium intake variations between men and women. Short rib soup for men and Korean sausage for women were the largest contributors to sodium variations, which are common dishes served with salt. Men consumed more drinks and also more sodium from drinks than women. In conclusion, there were significant differences in major dishes contributing to absolute and between-person sodium intake variations in university students between men and women. Further studies on effects of gender on blood pressure, sodium and drink intake, and obesity are necessary.

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.

For useful basic data in developing of Omandungi (Styela plicata) processed products, volatile flavor compounds were analyzed to identify the key reaction flavor compounds induced through heat treatment ($100^{\circ}C$, 10 min) in Omandungi -Doenjang (soybean paste) soups and stew. A total of 128 flavor compounds were identified and composed mainly of esters (16), aromatic compounds (14), N-containing compounds (11), alcohols (34), terpenes (5), carbonyl compounds (23), furans (4), hydrocarbons (13), acids (5) and miscellaneous compounds (3). Three groups including aromatic compounds, alcohols and acids were detected in high amounts in Doenjang. However, the levels of C4-C6 series acids (i.e., pentanoic acid having off-flavor) decreased by cooking ($100^{\circ}C$, 10 min), whereas that of furans (i.e., furfural) as heat induced compounds increased 2 times. Alcohols were detected the major group in Omandungi and followed by hydrocarbons and aromatic compounds in that order. In particular, 3 compounds including decenol, 2,6-dimethylheptanol and octanol were the major alcohols of Omandungi. By cooking, the compounds known heat-induced compound, 2-acetyl-2-thiazoline and benzothiazole, were newly formed in Omandungi-Doenjang stew. The alcohols (i.e., decenol, 2,6-dimethylheptanol), hydrocarbons and aromatic compounds derived from Omandungi were supposed to enhance a seafood-like flavor in Omandungi-Doenjang stew.
