This study aimed to examine the cooking methods used in the Joseon Dynasty using cooking books. We chose "Suwoonjabbang" (1500's) and "Eumsikdimibang" (1610) as the subjects of this study. Cooking methods from these two recipe books were categorized into staples, side dishes, rice cakes, Korean traditional sweets and cookies, drinks, fermented foods, seasonings, and storage methods. Firstly, "Suwoonjabbang" contains a total of 121 cooking methods divided into two volumes. In contrast, "Eumsikdimibang" includes 146 cooking methods. There are 18 methods for noodles and dduks, 74 methods for fish and meat, and 54 methods for drinks and vinegars, and others. Secondly, "Suwoonjabbang" written by Yu Kim in Chinese characters can be described in simple terms. It provides caution against indulging in the taste of food. In contrast, "Eumsikdimibang" by Kye Hyang Jang contains detailed cooking methods that have disappeared. Thirdly, "Eumsikdimibang" introduced more diverse cooking methods for noodles, dumplings, side dishes, rice cake, Korean traditional sweets and cookies, and fermented foods as compared to "Suwoonjabbang". In conclusion, unique cooking methods introduced in these two cooking books, which are rare these days, are expected to be further applied and developed.

The effects of $CaCl_2$, K-sorbate, and fermented fish sauces and blanching on the texture of Chinese cabbage of Kimchi were evaluated. The addition of salt-fermented shrimp or salt-fermented anchovy accelerated the pH reduction, acidity increase and reducing sugar consumption, but K-sorbate, Ca-chloride and blanching suppressed the ripening process of Kimchi. The latter retarded the softening rate of Chinese cabbage during Kimchi fermentation, as demonstrated by the cutting force, compression force, recovered height and work ratio. The sensory evaluation confirmed the results of instrumental texture measurments. The instrumental measurements, i.e. pH, acidity cutting thickness, cutting force and compression test parameters, showed acidity acidity was calculated as % lactic acid attributes, i.e. the preferences for taste, appearance and texture, and the level of crispiness, hardness, chewiness and fibrousness. The pH of Kimchi was appeared to be an important quality parameter, whiih had significant correlations with the taste, appearance, chewiness, hardness, fibrousness and crispiness.

This study examined the food culture of Koreans aged over 80-years-old living in the areas of Goorye and Gokseong. The research method was based on examination of individual cases through in-depth interviews. The total number of survey subjects was 38; males constituted 34 percent of the subjects while females constituted 66 percent of the subjects. Average age of male subjects was 85.3 years while average age of females was 84.8 years. The results were summarized in the following properties of the typical and traditional Korean table, which was the most common food life's property in the longevity area of was centered around rice, watery soup, vegetables, and fish. The first, as the supply step's property of food ingredients, various spices and ingredients such as piperitum, tumeric, ginger, garlic, chili pepper, and salted fish were used. Senior persons also supplied fresh vegetables at the kitchen garden, and they led a nature-friendly food life. The second, as the production of food and cooking of food step's property, there were multigrain rice and fermented foods such as soybean paste, kimchi, red pepper paste, salted fish, vegetables picked in soy sauce, etc. The recipe was cookery intermediated with water, soup, steamed vegetables, seasonings, etc., and it was characterized by a deep and rich taste due to the various spices and rich ingredients. The third, as the consumption of food step's property, senior persons regularly ate a balanced diet three times a day. They also had active personal relationships with their neighbors by sharing food, which increased their sense of belonging and improved their life satisfaction.

We investigated the quality of 12 commercial salted and fermented anchovy Engraulis japonicas sauces by measuring their chemical compositions, bacteria concentrations, and biogenic amine contents. The sauces had a moisture content of 67.13-69.83% (mean: 68.17%), salinity of 20.00-25.84% (mean: 22.29%), pH of 5.14-6.28 (mean: 5.63), volatile basic nitrogen content of 119.12-273.37 mg/100 g (mean: 199.19 mg/100 g), total nitrogen content of 0.82-1.50% (mean: 1.30%) and amino nitrogen content of 550.17-1,086.62 mg/100 g (mean: 774.99 mg/100 g). The viable cell counts ranged from not detected to $1.6{\times}10^3CFU/mL$, and the number of biogenic amine-forming bacteria was very low or undetectable. The tested samples contained 372.32-2,111,61 mg/kg (mean 813.48 mg/kg) histamine, 29.62-144.29 mg/kg (mean 98.14 mg/kg) cadaverine, 87.89-530.84 mg/kg (mean 329.91 mg/kg) tryptamine, 20.89-127.17 mg/kg (mean 60.49 mg/kg) putrescine, and 13.08-109.91 mg/kg (mean 57.74 mg/kg) tyramine. Whereas no spermidine or spermine was detected in any sample. These results strongly suggest the necessary of monitoring the biogenic amine contents of commercial salted and fermented anchovy sauces carefully to ensure consumer health.

The evolution of Korean fish fermentation technology was reviewed from the old literatures and the on-going processes were surveyed. The principles involved in the traditional fermentation methods were explained by the recent scientific findings. The fish fermentation technology be classified into two groups; jeot-kal process, where. salt is the only material added to the fish for fermentation, and sik-hae process, where cooked cereals, garlic and red pepper powder are added to the salted fish. A total of 46 kinds of jeot-kal was identified in a survey, depending on the raw materials used. The characteristic feature of Korean jeot-kal process is to produce fermented products which still has original shape after 2-3 months of fermentation to be used for side-dishes of rice meal, as well as fish sauce by keeping these products for longer time (over 6 months) for severe ansymematic hydrolysis to be used for the subingredient of Kimchi (Korean fermented vegetable food). The taste of jeot-kal is formed by the protein hydrolymates due to the action of salt-tolerant Pediococcus, Bacillus, Halobacterlum etc. When the taste of jeot-kal deteriorates, yeasts appear to dominate. In ski-hae fermentation, the safety of preserved fish is kept by the rapid decrease in pH resulting from the acid fermentation of added cereals. The roles of cid forming bacteria and proteloytic bacteria are important. The fermentation is completed in 2 weeks and the excess production of acid during prolonged storage limits the taste acceptability. The fish fermentation technology in Korea stands at important position in Korean food science and technology. since the processes of jeot-kal and soysauce have same root in the principle of microbial proteolysis and the processes of sik-hae and Kimchi in the microbial acid production principles.

Radish kimchi is a typical side-dish in Korean traditional food and is a way of keeping vegetables for a extended period using fermentation. This study examined the classification, usage, eating history, variety, and recipes of Korean radish kimchi through ancient and modern era literature. The Korean radish kimchi were categorized into six groups: kkakttugi, seokbakji (or nabakkimchi), dongchimi, jjanji, jangachi, and jangkwa. According to the record, the eating history of radish kimchi comes from before the age of the Three Kingdom period. Radish was preserved in salt, vinegar, soybean paste or lees of fermented liquor in the early times. This pickled radish was not supposed to be watery. Radish kimchi was divided into watery kimchi (dongchimi) during the period of United Silla and the Koryo Dynasty. Kimchi was mixed with Chinese cabbage to make seokbakji or nabakkimchi. Up to the early Chosun Dynasty, the key ingredient of kimchi was radish. After the middle of the Chosun Dynasty, kimchi was mixed with red pepper powder, salted fish, soybean sauce, and various ingredients. There were many kinds of radish kimchi during the late Chosun Dynasty. In the 11 Korean recipe books published within the past 100 years, there are nine kinds of kkakttugi, three kinds of seokbakji, four kinds of dongchimi, three kinds of jjanji, nine kinds of jangachi, and five kinds of jangkwa. Kkakttugi (cubed, sliced or julienne radish) was pickled with salt, red pepper powder, garlic, green onion, oyster, sugar, salted fish, and more. Seokbakji and nabakkimchi were not as salty, so they could not be preserved as long. Dongchimi (watery radish kimchi without red pepper powder) was made of radish, water, salt, 18 side ingredients, 13 condiments, and seven garnishes. Jjanji was pickled to be very salty and was eaten during summer. Jangachi can be used as a regular side dish and is made of radish or dried radish slices pickled or seasoned with salt, soy sauce, vinegar, soybean paste, lees of fermented liquor, and spices. Jangkwa is used as a stir-fry method and has been segregated from jangachi relatively recently.

A survey was conducted to investigate housewives' perception and consumption of Korean fermented foods marketed in Taejon. Most subjects know how to prepare Kimchi(seasoned and fermented vegetables), 65-67% can make Kochujang(fermented red pepper soybean paste), Toenjang(Korean style soysauce) and Jang-atchies(pickled basic side dishes), 56% can make Kuk-ganjang(Korean style coysauce), 45% can make Chonggukjang (fermented soybean) and 34% can make Jot-kals(salt-fermented fish products). With decreasing age(p<0.0001), not many other subjects could make other fermented foods besides Kimchi. The percentages of subjects buying fermented foods were 71.5% for Chin-ganjang(Japanese style soysauce), 51.7% Jot-kals, 27.1%Kochujang, 25.7% Chonggukjang, 20.1% Jang-atchies, 10.4% Toenjang, 5.9% Kuk-ganjang, and 3.8% Kimchi. the uounger in age, the higher the tendency to buy marketed Kimchies(p<0.05) and Kochujang(p<0.01). The resons for purchasing fermented foods were convenience (52.9%), lack of preparation knowledge(17.5%), lack of time for preparation(12.5%), and lack of space for food storage(8.2%). Subjects indicated that their reasons for mot buying were as follows : use of additives or unreliability with regard to manufacturing dates(45%), bad taste(21%), unsanitary treatment(16%) and to keep their indigenous taste(14%). They cosidered expiration dates, taste, crpteria and safety as the important standard in selecting marketed foods. Younger subjects insisted on the improvement of sanitary condition and partial change of taste to increase the consumption of fermented foods. However, older subjects thought it best to keep the taste original for more utilization of fermented foods.

This study investigated and compared chemical properties and biological activities of four commercial sikhae products (three flat-fish, Pleuronectes herzensteini, Sikhae: product A, B, C; one Alaska pollack, Theragra chalcogramma, Sikhae: product D) and Alaska pollack Sikhae (product E). Total acidity, amino nitrogen, salinity and pH in all products were in ranges of $0.47-1.93\;g\%$, $145.94-204.81\;mg\%$, $3.40-4.00\%$ and 4.38-5.55, respectively. All products showed antimicrobial activities against Bacillus ceraus subtilis, B. cereus, Staphylococcus aureus, Listeria monocytogenes, Vibrio parahaemolyticus, except for Salmonella typhimurium. Particularly the activities were more effective with gram positive bacteria than gram negative bacteria. Antioxidative $(EDA_{50};\;14.20\;mg/mL)$ and Fibrinolytic (0.95 plasmin unit/mL) activities of product E were much stronger than commercial Sikhae products (EDA50; 18.87-34.60 mg/mL and 0.69-0.85 plasmin unit/mL).
