This study was designed to establish Korean food culture by analyzing 17 sets of Jinyounuigue, Jinchanuigue, and Jinjarkuigue which were the records of royal party procedures in Yi dynasty, Analysis was made on royal parties in terms of table setting, kinds of dishes served, composition of foods, frequency of the food materials used, and food items changed over the period from 1719 to 1902, the latter half period of Yi dynasty. Foods used in those parties were classified into seven groups in this study; rice and noodoes, side dishes, Docks, desserts, fruits and nuts, beverages, and sauces. There were about 10 kinds of steamed rice and noodles including Mandoo and Byungtang, 140 different kinds of side dishes, 53 kinds of Kocks, 142 kinds of various desserts, especially Dasik and Korean cookies, 38 kinds of fruits and nuts, 10 kinds of beverages including Hwachae and Sujeongkwa, and 10 kinds of sauces such as soy sauce, mustard, honey, and etc. There was no tendency in omission or addition of food materials, but the number and heights of dishes were designated by the scale or character of the party. There were unique measuring units that were quite different from metric system. More than 30 different units were appeared in the differences. Most of them were used for typical items such as Sari for noodles only. However some were quite general and used until now. Mal and Dye were the units for volume, Kwan and Kuen for weight, and Chock and Chon for length.

The iron content of 178 food items were analyzed by ICP to provide database to calculate dietary intake of iron in Korea. The analysis data showed significant deviations of iron contents in some food items compared with Food Composition Table of KRNI which is most widely used at present. Three day dietary intake records were collected from 96 female college students to estimate mean daily iron intake and bioavailability of dietary iron. Mean daily intake of total iron in the study subjects was 13.2mg and heme iron intake was 0.94mg, 6.7% of total iron intake. BGioavailability of dietary iron was calculated by two methods. Total absorbable iron was calculated by the method of Monsen, body iron storage of the subjects being estimated with serum ferritin concentrations, was 1.21mg and bioavailability of dietary iron was thus 9.3%. Bioavailability calculated with the method by Hallberg was 11.22%. Two values of dietary iron bioavailability of the present study are lower than the reported values in adult women consuming typical western diets but within the range estimated for vegetarians. Considering high prevalence of iron deficiency based on serum ferritin concentrations and low bioavailability of diet in young adult Korean women, more efforts should be made to increase the content and bioavailability of iron in diet of Korea adult women.

This paper investigated monthly meal composition and type of foods prepared for Dalye (ancestor rituals) over a period of 1 year based on the records in Sakmangdalye-deungnok and reviewed the ingredients for Dalye foods. From the results of our survey, 19 to 20 dishes were served in Sakmangdalye. 24 to 25 different foods were served in Sakdalye. Foods for Sakdalye consisted of Silkwa, Jogwa-Gwapyun, Jeongkwa or Suksilkwa, Hwachae-Sujeonggwa, Tteok, Cho, Jeonyueo, Sugyuk, Jjim, Hwe, Po, Sikhye, Tang, main dish-Guksu or Mandu, and Jang. Ingredients used in Sakmangdalye were recorded in a very integrated and simple manner in Sakmangdalye-deungnok. All ingredients were categorized into three groups: Kwasil (Fruits), Byeongmisikseung (Rice cakes etc.), and Muyeok (purchases). Sakmangdalye-deungnok was helpful in consulting dishes and ordering ingredients when a table for Dalye was set. Moreover, it was written simply enough so those who were in charge of preparing food could easily understand. This paper establishes Sakmangdalye-deungnok as one of the key materials for Royal Cuisine.

This study investigates the Gabo Jaedong Jemuljeongnyechaek, which is the recording of the darye executed over a period of a year in 1834 ($34^{th}$ year of reign by King Sunjo) in the latter part of the Joseon Dynasty, two years after the death of Princess Bokon, the $2^{nd}$ daughter of King Sunjo. Accordingly, we examined the types of darye (tea ceremonies) and the characteristics of the composition of foods at ancestral rites of the royal families of Joseon. Moreover, we also analyzed the cooking methods and characteristics of food terminologies used in the darye. This includes 39 categories of food and ingredients used for tea ceremonies held for one year, on behalf of the deceased Princess Bokon in 1834. The darye for the monthly national holiday was held along with the darye on the $1^{st}$ and the $15^{th}$ day of every month. The darye for rising up and the birthday darye were held on May $12^{th}$ and October $26^{th}$ of the lunar calendar, being the anniversaries of the death and the birth of Princess Bokon, respectively. The birthday darye and the darye for New Year's Day, Hansik ($105^{th}$ day after winter solstice), Dano ($5^{th}$ day of the $5^{th}$ month of the lunar calendar), and Thanksgiving "Chuseok" were held in the palace and at the burial site of the Princess. During the darye for rising up in May and the Thanksgiving darye at the burial site in August, rituals offering meals to the deceased were also performed. The birthday darye at the burial site of Princess Bokon featured the most extensive range of foods offered, with a total of 33 dishes. Foods ranging 13~25 dishes were offered at the national holiday darye, while the darye on the $1^{st}$ and the $15^{th}$ of the month included 9~11 food preparations, making them more simplified with respect to the composition of foods offered at the ceremony, in comparison to the national holiday darye. The dishes were composed of ddeok, jogwa, silgea, hwachae, foods such as tang, jeok, jjim, hoe, and sikhae, and grain-based foods such as myeon, mandu, and juk. Foods offered at the burial site darye included 12~13 dishes comprising ban, tang, jochi, namul, chimchae, and jang. Meals offered at the darye had a composition similar to that of the daily royal table (sura). Darye recorded in the Jemuljeongnyechaek displayed characteristics of the seasonal foods of Korea. Jemuljeongnyechaek has detailed recordings of the materials, quantities, and prices of the materials required for preparations of the darye. It is quite certain that Jemuljeongnyechaek would have functioned as an essential reference in the process of purchasing and preparing the food materials for the darye, that were repeated quite frequently at the time.

Objectives: Based on the results from the Korean Total Diet Study (KTDS), the sodium (Na) and potassium (K) intake of Koreans were estimated and compared with intake estimates from the Food & Nutrient Database (FNDB), as in the Korea National Health and Nutrition Examination Survey (KNHANES) to verify the validity of these estimates. Methods: One hundred and thirty-four representative foods (RFs) covering 92.5% of the total food intake of Koreans were selected, and 228 pairs of corresponding 'RF x representative cooking method' were derived by reflecting the methods used mainly in terms of frequency and quantity in their cooking. RF samples were collected from three cities with a larger population size in three regions (nine cities) nationwide, and six composite samples were made for each RF, considering its regional and/or seasonal characteristics. One thousand three hundred and sixty-eight 'RF x representative cooking method' pair samples were prepared, and the Na and K contents were assessed using inductively coupled plasma atomic emission spectrometry (ICP-MS). The Na and K intake of the Korean population was estimated by linking the content with the food intake data from the 7th KNHANES. Results: The mean Na and K intake of Koreans were 2,807.4 mg and 2,335.0 mg per person per day, respectively. A comparison with the Na and K intake from KNHANES, including only RFs of KTDS, showed comparable results with less than 5% variation. While the contribution and ranking of food items to Na intake were similar between KNHANES and KTDS, there were differences in K intake. This was attributed to the large discrepancies in the K content of rice and coffee between KTDS results and the values in the 9th Revision of the National Food Composition Table used in KNHANES. Conclusions: The Na and K intake of Koreans estimated based on the KTDS, which performed nutrient analysis on samples prepared to a 'table-ready' state using foods of the representative collection, was similar and comparable with that of KNHANES. This supports the validity and usefulness of FNDB-based nutrient intake estimation at the population level. The list of nutrients studied in KTDS is expected to be expanded, allowing for intake estimation of nutrients with currently insufficient or absent information in the FNDBs in use.
