The history of vegetable preservation technology by salting and fermentation in Korea was reviewed from the Three Nations Era to the end of Chosun Kingdom, and the development of present day's Kimchi processing technology was traced back by using the classic books as well as recent review papers published in Korea. Although the written record on salting and fermentation of vegetables first appears in a 12th century literature (Dongkukisangkukjib, Gyu-Bo Lee $1168{\sim}1241$), the use of salted/fermented vegetables could be dated back to the Three Nations Era $(B.C.\;37{\sim}A.D.\;668)$ and even earlier period. The present type of Kimchi was gradually evolved after the introduction of red pepper into Korea in the 17th century. The descriptions on Kimchi fermention appeared in the literatures written in the period of $16th{\sim}19th$ centuries in Korea, Suunjapbang $(1500{\sim})$, Domundaijak (1611), Sasichanyocho (1656), Eumsikdimibang (1670), Chubangmun $(1600{\sim})$, Saekgyung (1676), Yorok $(1600{\sim})$, Sanlimkyungje (1715), Cheungbosanlimkyungje (1766), Kyuhapchongsoe $(1800{\sim})$, Imwonsipyukji (1827), Dongkuksesiki (1849) and Buinpylji $(1855{\sim})$ were reviewed.

The Chinese Sigyeong records the foods of the Primitive Pickling Period, pickling being a universal vegetable storage method, but does not indicate the origin of the pickled vegetables or the location of the source of transmission. Kimchi mainly used salt and sauce-based soaking materials at the beginning of the Fermented Pickling Period (beginning in the 1st to 3rd centuries A.D.), and it differed from the Chinese method, which used alcohol and vinegar. In the Umami-Flavored Pickling Period (beginning in the 14th and 15th centuries A.D.), jeotgal, fermented seafoods, were added, and pickles with a completely new identity were created, one different from any other pickles in the world. Lastly, entering the Complex Fermentation and Pickling Period (beginning in the 17th and 18th centuries), the technical process evolved using a separate special seasoning containing red pepper as the secondary immersion source after pickling in brine, the primary immersion source. As a result of this, kimchi was transformed into a food with a unique form and taste not found anywhere else. The unique characteristic of kimchi is that the composition of original materials, a combination of salted marine life and vegetable ingredients, is its core identity, and there is a methodological difference in that it is completed through a second process called saesaengchae (生菜)-chimchae (沈菜).

The softening of the femented vegetables and the fruits was resulted from the degradation of pectin substances, cellulose, hemicellulose by polygalacturonase(PG), pectinesterase(PE), Cx-cellulase, $\beta$-galctosidase. The conversion of insoluble pectin to soluble pectin in cell wall-middle lamella was a major factor in the changes of firmness. Ca2+ was substantially increased firmness. However, Ca2+ could be removed from cell wall by chelating agents such as oxalic acid and citric acid. And Ca2+ was replaced with Na+ by ion exchange reaction. Ca2+ deficient tissue was vulnerable to attack by PG. Preheating treatment and Ca2+ addition is most effective in inhibiting the vegetable food softening and in increasing middle lamella-cell wall regidity, which PE activation by preheating treatment and Ca2+ addition could created more anionic carboxyl groups for cationic materials binding such as Ca2+ and chitosan and for polypectategel formation. Excessive demethylation by PE was associated with loosening of middle lamella cell wall components and softening.

To investigate the effect of natural plants on the prolongation of optimal fermentation time of kakdugi, various kakdugies, added with hot water extract from 105 kinds of natural plants(68 medicinal plants and 37 vegetables), were fermented at 20oC until optimal fermentation time. In case of control without addition, the time required to reach the optimum acidity(0.6% lactic acid) was 60 hr. Among 105 kinds tested, 48 plant(42 medicinal plants and 6vegetables) extracts decreased the acidity after 60 hr fermentation to less than 50% of control. In addition, these extracts extended the optimal fermen tation time(>120 hr) by more than 2 folds. Moreover, among the above 48 kinds, 12 sorts of extracts raised the hardness of kakdugi, by more than 30%, compared to control. And the number of lactic acid bacteria in kakdugi added with the above 12 kinds was not smaller than that of control. In sensory test, 8 kinds of medicinal plants(including Phyllostachys edulis) were found to be acceptable. Based on these results, it is suggested that kakdugi added with 8 kinds of medicinal plants was adequate in the prolongation of optimal fermentation time of kakdugi.

This study was conduced to identify the preference and intake frequencies of traditional Korean foods by Chinese-Koreans in the Yanbian region of China based on the hometown of the female head of household. Data were collected from 261 Korean housewives living in Yanbian. Twenty-six kinds of daily food items were surveyed. Analysis of variance was used to compare the similarities and differences among the three groups, which were divided according to hometowns in North Korea, South Korea, and China. The results for the traditional Korean daily food preferences showed that housewives born in South Korea are more likely to prefer cereal soup, vegetables soup, and fermented rice punch than housewives from North Korea and China. Considering the intake frequencies of traditional Korean foods, Korean housewives born in China are more likely to eat boiled rice and a bun stuffed with seasoned meat and vegetables, as well as beef and vegetables cooked in a casserole than housewives with hometowns in South Korea and North Korean. In this article, similarities and differences in the preferences and intake frequencies of traditional Korean foods are discussed, and implications for nutritionists as well as food marketers are provided.
