The Guk had lessened to use Gang, Whak, Tang. The Guk was classified into cooking method as a soup stock, the used main substances, and the temperature of the Guk. According to the soup stock were divided clear soup, Tojangguk, and Gooumguk. Another classification of Guk by main substances were Yuktang (meat soup), Otang (fish soup), bongtang (poultry soup), Shotang (vegetable soup), Japtang (vary substance soup) and Yonpotang (soybean-curd soup), and by the temperature of the Guk were divided Doounguk (warm soup) and Naengguk (cold soup). In the thesis, according to the kinds of Tojangguk, the reference frequency to them, the adding foods in them, and the variety cooking method in the Tojangguk were analyzed by the cook books published from 1700 to 1988 in Korea. 1. There were 29 kinds of Tojangguk. 2. The main substances of Tojangguk were meat, poultry, fish, shellfish, vegetable, mushrooms and seasonings. 3. The Tojangguk was boiled with the rice water and fermented soybean paste and fermented soybean-pepper powder paste. For the development of taste were added beef, shellfish, dried anchovy, dried small prawn, and soup stock of beef bones in winter. Seasoning substances were green onion, garlic, black pepper, sesame powder and oil.

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.

Fermented seasoning pastes were prepared by Aspergillus oryzae and Bacillus subtilis using three edible insects, Tenebrio molitor larvae (TMP), Gryllus bimaculatus (GBP), and Bombyx mori pupa (SPP), with soybean (SBP) as a negative control. Volatile compounds were extracted by the headspace solid-phase microextraction (HS-SPME) method and confirmed by gas chromatograph-mass spectrometry (GC-MS). In total, 121 volatiles from four samples were identified and sub-grouped as 11 esters, 18 alcohols, 23 aldehydes, 5 acids, 10 pyrazines, 2 pyridines, 7 aromatic hydrocarbons, 10 ketones, 19 alkanes, 9 amides, 4 furans and 3 miscellaneous. TMP, GBP, SPP and SBP had 48, 54, 36, and 55 volatile compounds, respectively. Overall, 2,6-dimethylpyrazine and trimethylpyrazine were found by a high proportion in all samples. Tetramethylpyrazine, a main flavor of doenjang, a Korean fermented seasoning soybean paste, was identified as one of the major compounds in TMP, SPP, and SBP. SBP had benzaldehyde, hexanal, n-pentanal, and aldehydes and SPP with pyrazines.

The aim of this study was to elucidate the changes in the microbial community and biochemical properties of a traditional sweet paste during fermentation. PCR-denaturing gradient gel electrophoresis (DGGE) analysis showed that Aspergillus oryzae was the predominant species in the koji (the fungal mixture), and the majority of the fungi isolated belonged to two Zygosaccharomyces species in the mash. The bacterial DGGE profiles revealed the presence of Bacillus subtilis during fermentation, and Lactobacillus acidipiscis, Lactobacillus pubuzihii, Lactobacillus sp., Staphylococcus kloosi, and several uncultured bacteria were also detected in the mash after 14 days of main fermentation. Additionally, during main fermentation, amino-type nitrogen and total acid increased gradually to a maximum of $6.77{\pm}0.25g/kg$ and $19.10{\pm}0.58g/kg$ (30 days) respectively, and the concentration of reducing sugar increased to $337.41{\pm}3.99g/kg$ (7 days). The 180-day fermented sweet paste contained $261.46{\pm}19.49g/kg$ reducing sugar and its pH value remained at around 4.65. This study has used the PCR-DGGE technique to demonstrate the microbial community (including bacteria and fungi) in sweet paste and provides useful information (biochemical properties) about the assessment of the quality of sweet paste throughout fermentation.

This study was performed to assess the consumption of various seasonings (SNG), which are usually omitted from food frequency questionnaire(FFQ), and their contributions to nutrient intake levels. A dietary survey with FFQ , which surveyed the intake of 65 mainly uncooked food items, was conducted for 493 adults over 30 years of age from 373 households in a rural area of Korea. Household consumption of major SNG items-garlic , red pepper powder, fermented soy bean paste, oil, soy sauce , salt, etc- were estimated by a questionnaire completed by the housewives of the survey participants. The daily consumption of SNG items by each subject was determined by 3 methods ; dividing daily household consumption by \circled1 the number of household members. \circled2 the number of household members over 10 years of age and \circled3 the weighted number of houshold members calculated by the ratio of the RDA for energy. All three methods for calculating the daily personal consumption of seasoning gave similar results, which may have been partly due to the homogenity of family age distribution of the households in the study area. Therefore, the results of method \circled1 were used to determine the contribution of SNG to nutrient intake of subjects in this study. Daily intake of all nutrients were significantly increased by including SNG consumption in the measurements as compared to measuring intake by FFQ alone (p0.01). Percentages of total daily nutrient intake from SNG ranged from 2.3% in carbohydrate to 34.4% in fat. Nutrients with higher contributions from SNG were energy (8.4%), fat (34.4%), Fe(20.55) and $\beta$-carotene(17.9%). These results indicate that SNG consumption can contribute significantly to the intake of several nutrients and must be considered in surveys using FFQ.

As a part of the investigation for utilizing pearl oyster by-products, a rapid salt-fermented pearl oyster using commercial enzyme was prepared and also examined on the characteristics. The salt-fermented pearl oyster prepared by optimal condition, which was prepared by mixing of minced pearl oyster, 15% salt, and 1% $Protamex^\circledR$ and fermented for 4 weeks, was superior in hydrolysis degree (28.7%) and ACE inhibitory activity (92.6%) to salt-fermented pearl oyster prepared by other conditions, such as the use of whole tissue, different enzymes $(Alcalase^\circledR,\;Neutrase^\circledR\;and\;Flavourzyme^\circledR)$, different salt concentrations (20 and 25%), and different fermentation periods (2, 6 and 8 weeks). There were, however, some shortcomings with this product. It showed a dark green color and an unfavorable bitter taste. These shortcomings were improved by the addition of seasoning paste. The calcium and phosphorus contents of the seasoned salt-fermented pearl oyster were 64.2 mg/100 g and 71.6 mg/100 g, respectively, and the calcium content based on phosphorus was a good ratio for absorbing calcium. The total amino acid content of the seasoned and salt-fermented pearl oyster was 7,054 mg/100 g and the major amino acids ware aspartic acid (555.1 mg/100 g), glutamic acid (1,131.2 mg/100 g), alanine (658.2 mg/100 g), and lysine (695.5 mg/100 g). The seasoned salt-fermented pearl oyster, along with angiotensin I converting enzyme (ACE) inhibitory activity (98.3%), also showed a recognizable level (87.5%) of anti-oxidative activity.

This study was carried out to investigate the growth of pathogenic germ in fermented pork with Korean traditional seasonings. The samples, outside muscle of pork ham were cut by the shape of cube (7${\times}$12${\times}$2cm) and seasoned with five Korean traditional seasonings such as garlic paste (Tl), pickled Kimchi (T2), pickled Kimchi juice (T3), soybean paste (T4), red pepper paste (T5). The rate of meat to seasonings was same. The seasoned samples were fermented at -1${\pm}$1$^{\circ}C$ for 28 days. Microbial pathogens such as Escherichia coli O157, Listeria monocytogenes, Salmonella enteritidis were not detected in all paste and samples. When 1.5${\times}$l0$^3$ CFU/$\textrm{cm}^2$ of Escherichia coli O157 was inoculated, the numbers were slightly increased to 10$^3$-10$^4$ CFU/$\textrm{cm}^2$ at 3 days and gradually decreased to the level of inoculation at 18 days in all samples. In the inoculation with Listeria monocytogenes (8${\times}$l0$^4$ CFU/$\textrm{cm}^2$), the numbers were below 10$^3$ CFU/$\textrm{cm}^2$ during 28 days in T3 and T4, while they were increased to 10$\^$6/ CFU/$\textrm{cm}^2$ in Tl and T2 at 3 and 13 days respectively, and decreased to 10$^4$ CFU/$\textrm{cm}^2$. In the inoculation with Salmonella enteritidis (3${\times}$l0$^4$ CFU/$\textrm{cm}^2$), the numbers increased to 10$\^$5/ CFU/$\textrm{cm}^2$ at 18 days, but they were rapidly decreased to the level of initial inoculation at 23 days.

This study was conducted to investigate which food items are perceived as HANSIK (Korean food) in Korea. 562 males and females aged 20-70 were surveyed on 512 most frequently consumed dish items from 4th Korean National Health and Nutrition Survey if they perceive it as HANSIK. Dish items in kimchi, namul sukchae (cooked and seasoned vegetable) and jeotgal (salt-fermented food) category showed high response rate to be perceived as HANSIK. The response rate of twigim (frying foods) as HANSIK was low showing less than 70%. The response rate as HANSIK for foreign origin foods such as ramen and jjajangmyeon (black bean paste noodle) were lower than 25%. In jang yangnyum (seasoning) category, doenjang (soybean paste) and gochujang (red pepper paste) showed high response rate as HANSIK more than 90%. Females showed a higher response rate as HANSIK than males for most food items except several items of myen mandu (noodle and dumpling). The younger age group had higher HANSIK perception on many items of recently consumed foods, especially budae-jjigae (spicy sausage stew) (p < 0.001) and jwipo-jorim (braised dried filefish) (p < 0.001), implying that they already accept the common foods as HANSIK regardless of the origin. These results provide an information on the foods perceived as HANSIK among currently consumed common foods in Korea and these results can be utilized for establishment of HANSIK concept reflecting transition of dietary life in Korea.

Kochujang (Red pepper paste) is one of a traditional fermented seasoning foods having peculia. flavor. In present paper, the effects of microorganisms on the formation of volatile components of Kochujang during fermentation were observed. The volatiles of Kochujang were extracted by a steam-distillation under the reduced pressure and determined by gas chromatography and gas chromatography-mass spectrometry (CC-MS), respectively. During fermentation of Kochujang, Saccharomyces sp. and three strains of Bacillus sp. were isolated as main microorganisms participating in the formation of volatile components. According to the analytical results, tetrahydro geroniol, furfuryl alcohol, methoxy acecoptenone and myrtanal in Kochujang inoculated with Saccharomyces spl, 2-methyl-propan-2-ol, furfuryl alcohol an furfuryl-n-butyrate in Kochujang inoculated with Bacillus sp. B-1, 2-methyl-propan-2-ol, furfuryl alcohol and furfuryl-n-butyrate in Kochujang inoculated with Bacillus sp. B-2, and 2-methyl-propan-2-ol, furfuryl alcohol and n-propylbenzene in Kochujang inculated with Bacillus sp. B-3, were identified as major components, respectively.

A special form of questionaire was prepared and distributed to 502 housewives in seoul from Feb. 8th to 22nd in 1989. The results were as follows: In Cooking methods, they tended to follow in the steps of their mother, and it took about half an hour or an hour to prepare a meal. They cooked fried foods once or twice a month. Whenever they fried foods they need new oil. Followings were details of cooking method mainly used by housewives. Fishes were tended to be roast, vegetables to be dressing and seasoning. Highly milled boiled rice was best preferred as the cheif food, and it was cooked by following procedure; First rice was washed, and steeped in water for the time being. Next, the water was poured out and water was filled again, then rice with the water was boiled. Fish Chige was cooked in the way that fish was put into the boiled soup. Fermented sao-bean paste Chige was cooked using water in which rice had been washed. Hard-boiled beef with soy sauce was made using the method that soy sauce was properly poured after beef was boiled. A Spinach was boiled shightly with salty water. In view of those results, there were many cases that housewives did not only utilize their knowledge about foods in real dietary life, but also fell short of endeaver to do so. They chiefly made use of the cooking methods instructed from their mother or husband's mother. In conclusion, in order to illuminate housewives to have an exact nutritional knowledge about foods and cooking methods getting out of the loss of nutritions, nutritional education program must be provided for housewives.
