We confirmed the character impact compounds of the flavors of the soybean paste manufactured with the traditional and improved Meju, respectively, by using the following methods: gas chromatography (GC), sniffing tests and GC-mass. The soybean paste made with the traditional Meju had 12 compound groups that smelled like the soybean paste flavor, whereas the soybean paste made with the improved Meju had 7 compound groups of soybean paste flavor smell. We were easily able to determine that there is a difference of soybean paste flavor compounds between the soybean pastes made with either the traditional or the improved Mejus because the two soybean paste flavors are very different from each other.

Cultural conditions for mass production of the antagonistic bacteria, Bacillus subtills CAP141 against pathogens causing major airborne diseases to apple trees, effects of temperature, pH, carbon and nitrogen source in the culture broth were investigated. The bacterial growth was most vigorous when the temperature and pH of the culture broth was 30~35$^{\circ}$C and 7, respectively. As for carbon source, dextrose was best followed in order by dextrose(monosaccharide) > sucrose(disaccharide) $\geq$ saccharose (market disaccharides) > starch (polysaccharieds). Among different sugars, bacterial growth was favored by in the order of brown, black and white supars, indicating that the bacterial growth might be promoted by the minor elements presented as impurities in the less purified sugars. As for nitrogen source, organic forms were better to bacterial growth than inorganic forms, that is polypeptone was best followed in order by soy sauce, soybeen milk and inorganic nitrogens. Differences in bacterial growth among different forms of inorganic nitrogen were negligible.

The purposes of this study are to explore the management of Geang and to evaluate attitude of housewives toward it's management. The informations of this study were obtained from 720 housewives residing in various parts of Korea by using qustionaires during July 20 to September 10, 1985. The subjects were divided into several groups according to their ages, educational levels, careers, monthly incomes, numbers of family, areas of residence and types of housing. The $x^2$-test was applied to test the indivisual data, The following observations were made in this study : Soybean pastes and soy sauce such as Doh-an jeang, Gohoojeang and Ganjeang were prepared domesically in most cases and about 80% of the subjects performed this labor annually. Only 10% of the household used commercial Geang. The most widely used commercial Geang is Ganjeang.

The objectives of this study were to identify the pickled garlic's attributes and verify the structural relationships among the attributes, customer satisfaction, and intention of repurchase. In order to achieve the purpose of this study, literature review and empirical study were used. As the results of this research are as follows. A majority of respondents answered that they preferred pickled garlic with soy sauce. And they were down on the lack of variety in pickled garlic products and garlic recipes. The nutrition facts and the value of producer of pickled garlic were verified to examine the effects on consumer satisfaction and intention of repurchase.

The conditions of water extraction form the dried jujube (Zizyphus jujuba) were examined. The general components, taste, and effect of taste correction of jujube water extract concentrate (JWEC) were investigated. desirable condition for extraction was that 100g of dried jujube was added to 750$m\ell$ of water and heated for 80 minutes at 100$^{\circ}C$. The yield of JWEC was 50% and the manin component of it was sugar (90%). The major taste of JWEC was sweetness, and it had astringent, bitter, sour and salty tastes as incidental taste. The taste was changed to desirable taste when 15% of JWEC was added to coffee, 10% of JWEC was added to fermented soy sauce, thick soypaste mixed with red pepper, and vinegar, respectively.

In order to use as a starter after drying, optimum growth conditions of Str. thermophilus and L. bulgaricus were investigated. The results were as follows. The growth of Str. thermophilus was reached at stationary phase after 12 hours incubation and L. bulgaricus was after 6 hours. Str. thermophilus was grown well, in the medium containing 10% of skim milk, 2% of sucrose, 0.1% of KCl and 0.015% (v./v.) of soy-sauce. In the case of L. bulgaricus, 10% of skim milk, 2% of glucose, 0.5% of bacto-peptone, 0.1% of $K_2HPO_4$ and 0.02% of pyridoxine was suitable for the maximum growth.

The cultural conditions of the osmophilic red color yeasts (Strain L${1$, $L_2$, $L_3$ and $L_4$) isolated and identified in the previous report were examined and the results obtained were as follows ; 1. The optimum medium for growth of these osmophilic red color yeasts was soy sauce medium. 2. These strains were grown exceedingly well on the medium containing 3 percent of NaCl but somewhat restrained on the medium containing 6% or more. 3. The optimum temperautre for growth of these strains was $25^{\circ}C$ and their lethal temperature was $68^{\circ}C$(treatment for 5 minutes). 4. The optimum pH for growth of these strains was 6.0.

Serratia marcescens가 생성하는 단백질 분해효소를 연구하기 위하여 효소의 활성도를 규명한 결과는 다음과 같다. (1)단백질 분해효소의 활성은 PH6.0과 PH7.5의 두 범주에서 최대로 나타났다. (2)45$^{\circ}C$에서 효소의 활성도가 가장 높았다. 이러한 결과로 미루어 볼때 Serratia marcescens의 단밸질 분해효소는 중성 PH 범위에서 안정된 효소활성을 갖는 것으로 생각할 수 있으며 다른 효소에 비해 비교적 높은 온도에서 활성도가 더욱 좋음을 알 수 있었다.

About 760 papers and patents of the traditional fermented food in Korea were collected which were published during 1917-1988, and then the papers were classified, outlined and reviewed. Study of traditional fermented food was about 10% of total study on Korean Foods, and that of alcoholic beverage was 50%, soy sauce and related product was 30% and kimchi was less than 20% of total study of traditional fermented foods. Though considerable amount of studies were accomplished before the World War II, but a few study was accomplished during the Korean war. The research activity is, hitherto, increasing gradually, but the systematic studies were rarely done. The studies to be investigated were processing quality of raw materials, classification, standardization, sensory quality of the product and so on.

In order to control the quality and safety of cooked foods, production and holding methods of foods should be carefully studied and applied to the foodservice industry. Therefore studies on microbiological, nutritional, physicochemical and sensory quality are essential in this area. The purpose of this study was to evaluate the chemical and microbial qualities of cooked foods during preparation and holding From the results, the following guidelines should be adhered to give effective quality control when holding foods after cooking in foodservice institutions, as well as to provide quality foods when selling cooked foods at commercial establishments. Sauteed and simmered foods such as sauteed chicken meat & vegetables and simmered pork in soy sauce satisfy the standard for microorganisms till 1-3 hours of room temp. holding, 6-18 hours at 60$^{\circ}C$ steam table, and 12-18 hours at 80$^{\circ}C$ heating table.
