Moderate halophilic bacteria isolated from several kinds of salted and fermented sea foods (jeotkal) collected from commercial market were identified and investigated on their selt requirements. It was confirmed that the isolates were dominantly moderate halophiles according to their NaCl requirement to grow. And their salt requirements in their growth have been examined for Na, K, Ni and mg ions. Among them, the most dominant and distinctive three strains in protease pro-duction have been examined and two of them identified to be halophilic Flavobacterium sp., and the other one to be halophilic Pseudomonas sp..1'heir optimum growth was observed at 3$0^{\circ}C$ and at 10 percent of NaCl.

This study examined the food culture of the Koryo Dynasty during the early 13th century based on the records of wooden tablets and marine relics from the 1st and 2nd ships of Mado wrecked at sea off Taean while sailing for Gaegyeong containing various types of grain paid as taxes and tributes. The recipients of the cargo on the 1st ship of Mado were bureaucrats living in Gaegyeong during the period of the military regime of the Koryo Dynasty, and the place of embarkation was the inlet around Haenam (Juksan Prefecture) and Naju (Hoijin Prefecture) in Jolla-do. On wooden tablets were recorded 37 items of rice, cereal, and fermented foods. The measures used in the records were seok [石-20 du (斗)] for cereal, seok [15 du, 20 du] for fermented soybean paste, and pot (缸) and volume (斗) for salted fish. The places of embarkation on the 2nd ship of Mado were Jeongeup (Gobu Prefecture), Gochang (Jangsa Prefecture, Musong Prefecture), etc. On wooden tablets were recorded 29 items of rice, cereal, fermented foods, seasame oil, and honey. The volume measure for yeast guk (麴), the fermentative organism for rice wine, was nang [囊-geun (斤)], and the measure for sesame oil and honey, which were materials of oil-and-honey pastries and confections, was joon (樽-seong, 盛). Honey and sesame oil were luxury foods for the upper-class people of the Koryo Dynasty, and they were carried in high-quality inlaid celadon vases in Meibyung style. Food names and measures written on wooden tablets and actual artifacts found in the 1st and 2nd ships of Mado are valuable materials for research into agriculture, cereal, and fermented foods of the Koryo Dynasty in the early 13th century. Besides, relics such as grains and bones of fish and animals from the Koryo Dynasty are expected to provide crucial information usable in studies on food history of the Korean Peninsula.

A new lactic acid bacteria with gluten-degrading activity which was isolated from salted sea foods (traditional Korea fermented food), identified as Weissella confusa (99%) by use of API kit and 16S rRNA sequencing, and designated as W. confusa. When the W. confusa cultured for 48 hours at $30^{\circ}C$ in a MRS medium containing 1% gluten, 45% of gluten was founded to be degraded. W. confusa showed 85% of survival rate at pH 3, and 94% tolerance at 0.1% oxgall, which indicates that W. confusa would survive in stomach of human. Experiments on the thermostability was confirmed that it has a stability of 70% in $50^{\circ}C$. W. confusa inhibited the growth of some pathogen, except for S. aureus. Results in this study suggest that using W. confusa for fermentation of grain flour containing gluten would be desirable to prepare the gluten-free foods needed for those who suffer from celia disease and gluten allergy.

To investigate the quality retention method of salted and semi-dried mackerel fillets, pH, volatile basic nitrogen (VBN), trimethylamine (TMA) and total bacterial counts in the fillets that were UV treated for 1, 3, and 4 hr were periodically measured during 48 days of refrigerated storage. The moisture, crude protein, crude lipid, and ash contents were 45.46 %, 18.87 %, 33.75 %, and 2.99 %, respectively. The freshness as determined by pH measurement could be maintained up to 25 days for the control and 31 days for the UV-treated fillets. VBN contents were continually increased over the storage time. The control reached the initial putrid level after 21 days while the UV-treated fillets after $25{\sim}31$ days. A similar tendency was shown for the changes of trimethylamine TMA contents, although the period differed slightly and the increase of the UV treatment time could decrease the TMA contents. The changes on the total bacterial counts of the fillets were maintained under 105 CFU/g during 48days. Especially, due to the effective decrease of the microorganism count by UV treatment at the beginning of the storage, UV -treated fillets showed lower bacterial counts than control over the whole period. E. coli. and Listeria were not detected in any fillets. Combining the above data and the sensory changes, the storage period of the fillets could be prolonged from 15 days at present to 30 days by UV treatments.

This study was conducted to investigate the contemporary dietary life of residence in Kyunggi province. People living in Kimpo, Yoju districts(farm villages), Kapyung districts (mountain villages) and Hwasung districts (fishing villages) were selected for this research as subjects from August S to 19,1997. The results of the survey are summarized as follows: 1. Cooked rice was a staple food. However nuddles and soojaebees(soup with dough flakes) was taken as lunch or snacks but Juk(rice guel) or Dduk(rice cake) was not treated as a meal. 2. Dishes were consisted with soup or chigae, kimchi and namul(seasoned vegetables), and fishes, meats, salted sea foods, dried fishes, jangacchi(dried seasoning radish) were also taken by sometimes. 3. Soy sauce, bean paste, red pepper bean paste were made by every home even if they were very busy. 4. Festival days such as New Year's Day, daeborum(the 15th day of January), chusok(mid-autumn festival), and kosaa(October ceremony) and dongee(one of 24 seasons by lunar calendar) are skipped oftenly and slowly forgotten by people. They do not celebrate Samgin-nal(the third day of March), Buddha's birthday(the 8th day of April by lunar calendar), danoh(the 5th day of May), yoodoo(the 15th day of June), chilsok(the 7th day of July), Jungyang(the 9th day of September) and the last day of the year either 5. Due to improved kitchen system, we couldn't see the old kitchen devices.

Nitrate and nitrite, which readily produce N-nitrosamines by reaction with secondary amines, are widely distributed in natural products such as vegetables and cereals, and are also used as a color fixation in meat products or fish roes. This experiment was carried out to determine the contents of nitrate and nitrite in foods such as fermented sea foods and fresh vegetables purchased at markets in Korea. The contents of nitrate were $0.74\sim13.81\;ppm$ for fermented sea foods and $4.0\sim1,572.5\;ppm$for fresh vegetables. As for vegetables, the nitrate levels of edible herbs were relatively higher than those of greens, fruits and rootcrops. The nitrite contents in fermented demoisells(Chromis notatus), fermented shrimp, fermented small squid, fermented anchovy and salted Alaska pollack roe were very little, while those in fermented hairtail and fermented entrails were not detected. As for vegetables, nitrite levels found for cabbage and lettuce were relatively as high as 3.8 ppm and $2.5\sim2.9\;ppm$, respectively, but were not detected in Korean cabbage, green perilla leaf, pepper, garlic and burdock. Of vegetables, the nitrate values in the outer part of Korean cabbage, stems of water cress and leaves of green onion were higher than in the other parts. Little variety of the nitrate levels were found during 4 days storage. In the comparison of low temperature storage and room temperature storage, lettuce, pumpkin and spinach contained higher levels of nitrate at low temperature storage, while eggplant and green onion, at room temperature storage.

The changes of microflora during fermentation of low salted sardine were observed. The viable cell count in the low salt fermented sardine with $8\%\;or\;10\%$ salt showed lower than that of control ($20\%$ salt) during the fermentation period and it was considered that the microbial growth was controlled by adding ethanol, sorbitol and lactic acid. Among 48 strains isolated, 7 genus of bacteria and 1 genus of yeast were identified during the fermentation of sardine. The changes of microflora also occurred during fermentation depending on the salt levels in the product. Brevibacterium, Pseudomonas, Flavobacterium and Baciilus were detected at early stage of fermentation and they disappeared after 50 days fermentation from the product with $20\%$ salt and Halobacterium, Micrococcus, Pediococcus and Torulopsis were isolated, whereas Brevibacterium, Micrococcus and Pediococcus were isolated from the product with $8\%\;or\;10\%$ salt.

The Gwugonsiuebang is a book of Korean woman's life in the Yi dynasty which published I 1653 by Mme. Jang. I have studied the food habits of the Yi dynasty that wrote in Gwugonsiueband as following. The staple foods are Guksu (wheat vemicell as like western noodles) 5, Mandu (bun stuffed with seasoned meat and vegetables) 6 kinds in this book. the side dishes are Guk (soup) 8, J'm (steamed meat or fish) 6, chae6, Nooruemi 5, Hyae (sliced raw fish) 3, Jockpyun (jellied beef soup) 3, Jockgall (salted sea food) 2, Jock (skewer or broach) 2, jihee 2, Sun (Steaming of stuffed vegetable) 1, Bockuem (saute) 1, Jon (pan fried fish) 1, Gui (meat or fish grilled with seasoning) 1, and the other 13 kinds. The desserts are D,ock (Korean rice cake) 11, jabgwa 8, Beverages 5 kinds and Jungwa 1 kind. The alcohol and fruits wine are 51 kinds. The alcohol and fruits wine are 51 kinds. The seasonings are Soybean sauce, oil, Sesamol oil, pepper, Ginger, Garlic, Vinegar, Wine, Salt, Bean paste etc. Raw materials of Guksu, Mandu, D'ock, Jabgwa, Beverage, Wine, vinegar are all carbohydrates. It shows that a tendency of Korean people too much take a carbohydrates. Now and then, there are no special difference of winter over pass for vegetables, fruits, dried beef, dried fish and salt fishes. In yi dynasty, there are 62 kinds of table ware and cooking kitchen utensils, but many of them come to uselessness. 19 kinds of measuring unit are very non-scientific because that is not by weight but by bulk or volume. There are many food making terms which are 198 kinds of prepared cooking term, 11 kinds of cutting term and 20 kinds of boiling term. And 10 kinds of expression of taste can see this book.

As a method of utilization of sardine, sardinops melanosticta, proper processing conditions for a low salt fermented sardine were investigated. And changes of chemical components during fermentation and the effects of additives to improve the quality of the product were also discussed. A low salt fermented sardine was prepared with 8 or $10\%$ of salt and various contents of additives such as lactic acid, sorbitol, glycerin and ethanol as preservatives and flavor enhancers, and fermented for 80 days at $29\pm3^{\circ}C$. Judging from the changes in pH, amino-nitrogen and volatile basic nitrogen during fermentation of low salted sardine and the organoleptic evaluation on their flavor, the products of sardine meat containing 8 or $10\%$ of table salt, $0.5\%$ of lactic acid, $6\%$ of sorbitol and $6\%$ of ethanol as additives were most desirable when fermented for 60 days.

This study was intended to outline the characteristics of the food culture in the area of Kyungsangnamdo and its modernization by interpretation and analysis of the novel Toji, which was set in Hadong, Jinjoo in the area of Kyungsangnamdo in the early 20th century. The characteristics of the Kyungsangnamdo area's native dish during the Japanese ruling era in the latter half of the Choson dynasty are as follows. In the first part of the novel, which spans from 1897 to 1908, vegetable and grain food development can be seen in the area of Hadong, the interior plains of Kyungsangnamdo, where there is a typical farming village in the mountains. The second part of the novel, which spans from 1911 through 1917, includes some mentions of the properties of Kyungsangnamdo area's native dishes through the lens of emigrated Koreans living on Gando island. Gando island is in China, and is where Seohee, the heroine, escapes from her homeland and remains for a period of years. There is a unique type of seafood in the Gando area using fresh marine products, exactly the same as in the Kyungsangnamdo area. The third part of the novel spans 1919 through 1929, after Seohee returns to her own country and regains her house. There is a noticeable description of food culture in the area of Jinjoo in Kyungsangnamdo through the description of Seohee focusing on the education of her children. The well-described features of Jinjoo are boiled rice with soup of beef leg bones and Jinjoo bibimbob, with vegetables and a variety of foods using cod. Cod are caught in large quantities in Kyunjgsangnamdo, and cities in the area grow to medium size as the area became traffic-based. The fourth part of the novel spans from 1929 through 1938, and includes very detailed descriptions of characters and background locations. Salted fish combined with the wild ingredients of Mt. Jiri feature prominently in the Kyungsangnamdo's area descriptions. The fifth part spans from 1940 through 1945, and as the Japanese colonization era ends, the foods described in Kyungsangnamdo seem to develop the usage of soybean paste. With abundant fish and shellfish Kyungsangnamdo, the dishes that evolve to use soybean paste include mussel soybean paste soup, picked bean leaves in soybean paste, chaitgook - cold soup from soybean paste, and seolchigook used with seaweed and sea laver.
