This article examines the types of tteok (Korean rice cake) recorded in 21 old literatures of the Joseon dynasty (1392-1909) according to its main ingredients. Tteok varieties of the Joseon dynasty were categorized into jjin-tteok, chin-tteok, jijin-tteok, salmeun-tteok and guun-tteok and their changes in cooking method were discussed from the early to late eras of the Joseon dynasty. These can be summarized as follows. In the early, middle and late eras of the Joseon dynasty, there were 1, 15 and 84 kinds of tteok using non-glutinous rice as the main ingredient, and 6, 24 and 120 kinds using glutinous rice, respectively. Tteok using wheat flour was not found in the early Joseon dynasty, whereas 6 and 32 kinds were found in the middle and late eras, respectively. There were 1, 4 and 5 kinds of tteoks using buckwheat, and 5, 11 and 19 kinds using other ingredients such as yam, barley, elephant's ear, oat, and arrowroot flour, in the early, middle and late eras, respectively. The frequency of the main ingredient increased in the order of glutinous rice>non-glutinous rice>wheat flour>other ingredient>buckwheat flour during the Joseon dynasty and the ratio of tteoks using non-glutinous and glutinous rice flours was 1:1.5. The number and types of tteok were noted to increase abruptly throughout the Joseon dynasty. This may be associated with the commercial industrial development that prevailed in the late Joseon dynasty. Further study will be conducted on their recipes and ingredients recorded in these old literatures to develop a standardized recipe for the globalization of tteok.

This study aimed to evaluate the changes in the content of functional components and antioxidant activity of rice and barley according to the milling process used. A considerable amount of γ-oryzanol was observed in unmilled rice and barley. However, γ-oryzanol was not detected in the rice and barley after the milling process. The highest content of γ-aminobutyric acid (GABA) was observed in the unmilled Keunalbori-1-ho barley. The contents of biotin in all samples also decreased in the milled grains compared to the unmilled grains. The highest content of total polyphenols and flavonoids was observed in the Heuksujeongchal barley, and the highest radical scavenging activity was also found in this grain. The milling process led to a decrease in the content of functional components, including γ-oryzanol, GABA, biotin, polyphenols, and flavonoids in both rice and barley. These results may be useful in the development of processed foods using cereal grains.

The purpose of this study was to select an ingredient acting as a natural emulsifier to retard the retrogradation of rice cake by the measurement of mechanical characteristics of the cakes. For the purpose, Backsulgi, the most basic type of rice cake, was prepared by adding various ingredients having high contents of lecithin such as raw soybean powder, parched soybean powder, soybean oil, egg yolk powder, and the measurements and observations on the chromaticity, swelling power, pore ratio and cross-section were made. In addition, changes in the textural characteristics of Backsulgi samples were determined while storing them at the temperatures of 4$^{\circ}C$ and 20$^{\circ}C$ for 0, 1, 2 and 3 days. The results of the study were as follows: 1. In terms of chromaticity, the Backsulgi samples added with egg yolk powder, raw soybean flour and parched soybean flour were higher in yellowness(b) than the controls. 2. Both swelling power and pore ratio of Backsulgies added with raw soybean flour were higher than those of controls. 3. A cross-sectional observation using an electron microscope indicated that rice flour particles of controls had uneven pores and were conglomerated in a large lump while Backsulgi samples of raw soybean flour or roasted soybean flour had large and even pores and showed loosened bonding to be transformed into a sponge shape. 4. In hardness, Backsulgi samples added with raw soybean flour had less changes in hardness than that of controls, indicating that the effect of retarding retrogradation was higher when the storage time got longer.

This study investigated changes in the chemical and functional components of germinated rough rice for the development of functional foods. The chemical components that were determined for 'Ilpum', 'Goami2', 'Keunnun', and 'Heugkwang' rough rice cultivars included dietary fiber, free sugars, free amino acids, and functional components such as tocopherols and ${\gamma}$-oryzanol. The crude protein, fat, total dietary fiber, and free sugar contents of the rough rice increased significantly after germination. The essential amino acid content was particularly increased. After the germination of the 'Ilpum', 'Goami2', 'Keunnun', and 'Heugkwang' varieties, the following increases were found: ${\gamma}$-aminobutyric acid increased 2.4, 2.5, 6.1, and 3.4 times, respectively; ${\alpha}$-tocopherol, ${\alpha}$-tocotrienols, and ${\gamma}$-tocotrienols increased significantly; and ${\gamma}$-oryzanol content increased 0.8, 1.1, 1.5, and 1.2 times, respectively. Thus, germinated rough rice has the potential to be used as a healthy and functional food ingredient.

The purpose of this study was to investigate changes in the cooking process of $Bibimbab$(cooked rice mixed with various ingredients) appeared in cook books published after Korean modern era, approximately from late 19th century to the present. 7 cook books were chosen to be analyzed. It is found that the ingredients were mixed with the rice before being served in the cook books written in late 19th century until mid 20th century, while the ingredients were separately decorated on top of the rice in the cook books written from mid 20th century until late 20th century. $Gochujang$(Korean chilly paste), which is common spicy seasoning for $Bibimbab$ in the present time, appeared only in $Hangukeumak$(1987) which is written in late 20th century. Prior to $Hangukeumak$(1987), chilly powder or chilly was used for chilly-based spicy seasoning. Cook books written in late 19th century until mid 20th century, ingredients used for $Bibimbab$ had complicated cooking methods such as $Jeonyueo$(assorted pan-fried delicacies), $Nurumi$(fried beef skewer with various vegetables) and $Sanjeok$(grilled beef skewer). From mid 20th century until late 20th century, among the cook books analyzed in this research, only $Hankukyoribaekguasajeon$(1976) suggested $Jeonyueo$ as an ingredient, and in general, the cooking method for preparing beef became simpler. For further studies, firstly, the cooking procedures used for $Bibimbab$ in the prior period to the Korean modern era need to be examined for more information about the changes of cooking style of $Bibimbab$. Secondly, new $Bibimbab$ recipes for modern restaurants could be created by using the recipes used in the historical cook books. Finally, the definitions of culinary terms used in historical cook books need to be clarified.

Jeol-sik, (festive seasons every 15 days based on sun cycle), refers to both Korean Traditional Festival food(jeol-sik), intertwined between months, and in-season meals(si-jeol-sik) in which the ingredients used are produced in each and one of the four season. Si-jeol-sik is a kind of recommendatory food, which is combined to seasonal changes. I found that ingredients in Si-jeol-sik of spring are helpful for strengthening one's life force. Moreover, the ingredients also reflects seasonal changes. The main ingredient of Si-jeol-sik in January(in lunar year) is rice. Rice is good for upgrading one's stomach qi(energy). Rice continues to be used in February. In addition, some greens are included in February Si-jeol-sik as to help defecation. In March, the ingredients become diverse and abundant. The main concern in the ingredients found in March is not limited to stomach qi. These changes of ingredients are in line with the concept of 'health maintenance', which is written in Huangdi Neijing. The writing teaches the wisdom of adaptation to nature. Si-jeol-sik's basic idea is maybe giving people some food, which includes useful elements to help them survive through a season or the next season. They can be also explained properly by the help of five flavours theory. According to Huangdi Neijing liver is main organ of spring. So liver is more important than other organs in spring. And the most efficient way for liver is supplying sweet or sour food. Interestingly, there are many sweet elements in Si-jeol-sik of spring.

Fermented foods available in Korea may be classified into four groups, namely, fermented soybean products, fermented cereal products, fermented vegetable products, and fermented fishery products based on raw materials used. The representative fermented foods based on soybean are Kanjang(soysauce), Doenjang(fermented soybean pastes), and Kochujang(red pepper added-fermented soybean paste). Such fermented products are made using Meju(functioning as a starter and prepared by fermentation of steamed soybean mash) as an essential ingredient, and used widely as a soup base and/or in seasoning side-dishes for everyday meals year around. Excepting Sikhae, all fermented products based on rice and other cereal grains are of alcoholic nature. Takju (Makgeolli) used to be made using rice as the major raw material, however, mainly due to the shortage of rice in recent years, other cereals, such as, barely, corn, and wheat flours are also used to replace rice today. Owing to such changes in the raw materials. the popularity of Takju has been somewhat reduced, yet it is still widely consumed in rural areas. Although Chungju is a popular rice wine with superior qualify over Takju, the amount consumed is considerably limited. The highest qualify rice wine, Bupju, in particular, is made by a low temperature fermentation using glutinous rice. Kimchi is an unique fermented vegetable product of long tradition in Korea. Although it was for consumption mainly in winter season serving as a source of vitamins, today it is widely used throughout the year. Except Kkakdugi and Dongchimi, all of the fermented vegetable products contain salted Korean cabbage as an essential item, while they abound in varieties depending on material composition and methods of processing, and also on seasons and localities Next to Kimchi in this category is Kkakdugi made of raddish in popularity and quantity consumed. The four groups of fermented food products described above are reviewed in some detail and evaluated in terms of their nutritional significances, processes and microorganisms involved. and their commercial potentials. Jeotkal (or Jeot) is a name given to all fermented products of fishery origin. A number of Jeot can be prepared by adding salt and allowing fermentation to the raw materials such as shrimp, anchovy octopus, clam, oyster, etc.
