Changes of Microflora, enzyme activity, and contents of several taste compounds in traditional Kanjang(Korean Soy Sauce) with the variation of fermentation jars and Meju(fermented soybean brick)concentration were studied. Substitution possibilities of clay jar with glass jar and improvement possibilities of taste and nutritional value with increased Meju concentration were examined. (1) Aerobic bacteria and lactic acid bacteria were enumerated during fermentation and ripening period. But yeast and molds were hardly isolated. The number of viable cells showed small changes during fermentation and ripening period. (2) Isolated Aerobic bacteria were identified as Bacillus subtilis, Bacillus lichenformis, and lactic acid bacteria were identified as Lactlbacillus lactis lactis and lactobacillus brevis. (3) The activities of $\alpha$-amylase and $\beta$-amylase increased during fermentation period, but did not show any trend by fermentation jars or Meju concentrations. Protense activity showed small difference among four samples, and increased during the fermentation period.

Among the many foods, it is hard to find perfect food with nutrition and functionality like beans. Korean food culture is the main ingredient of korean culture, kochujang, soybean paste, and soy sauce, and processed soybean tofu is the main ingredient. Soybean meets high quality protein and fat, and it has excellent results in prevention and treatment of all kinds of diseases. Soybean food is becoming a new generation health food. In countries where animal protein intake is low, soybean is used as a protein source instead of animal protein. Tofu, a processed food, is a complete food with high digestibility. In order to publicize the superiority of soybean nutritional value, Tofu processing and powder were investigated by observing the size, shape and characteristics of bean powder using domestic soybeans and imported soybean, and the variation of the amount of coagulant.

In order to help food habits of Korean, major foods of side dishes in Korean foods were analyzed by Mohr's Silver Nitrate Method. The kinds of foods were Kanchang (Sa)Sauce) Kochuchaag(Redpepperbean paste), Doeuchang(Soy bean Paste) and Kimchies, and selected into 3 areas in Korea; Seoul (city area), Kyung Puk Province (Fishery area) and Chun-Puk Province (Farming area). The results are as follows; Average NaCl content of Kan-chang is 26.04g/dl ranged from 24.27 to 28.22g/dl and among them Farming area is the highest content. In Ko-chu-chang, average content is 11.36g% ranged from 10.77 to 11.60g%. Doen-chang has an average 15.89% ranged from 13.28 to 18.54g% and in Kimckies they were resulted 3.36g%.

With the intention to examine the Korean bean "Meju" and wine "Kokja" fundamentally we accomplished first the examination of Aspergillus Oryzae in them as follow; 1. 22 kinds of Aspergillus Oryzae were isolated from Korean bean "Meju" and wine "Kokja" 2. Microscopic and physiologic characteristics were surveyed. 3. 5 kinds of powerful moulds in amylolysation and 4 kinds of powerful moulds in proteolysation were found. 4. The moulds isolated from the bean "Meju" were superior to "Kokja's" coulds in amylolytic power and proteolytic power.

The purpose of this study was investigated kinds and utilities of Jeot-kal(fermented fish products) in 55 different regional area which were classified three temperature zone. The result were as follows ; (1) 95 kinds of jeot-kal found, they were subdivided 4 groups according to types and part of fish used : whole fish(46 kinds), vicera(11 kinds), shellfish(14 kinds), mollusca(4 kinds) and crustaceans(20 kinds). 17 kinds of jeot-kal were found in all area. (2) They were used as side dish, seasoning substitution of soy sauce or vinegar and important materials of kimchi. In Kimchi, 49 kinds of jeot-kal were used and Myeolchi Jeot(self-fermented enchovy) was prefered at southern area, saewoo jeot (self-fermented small shrimp), gonjengi jeot(self-fermented Mysis), hwangsegi jeot(self-fermented Hwangandali) were prefered at nouthern and middle area. Sometimes they were used in sacrified service. (3) Salt content and pH of jeot-kal at southern area were higher than other area.

The study examined the preference and style of consumption of perilla leaves(Perilla frutescens var. japonica Hara), a popular food item in Korea, by consumers in the Daejeon area. Of the respondents 35.2% purchased perilla leaves in a large super-market limited to two to three bundles. Comsumer preferences were to consume the leaves raw or pickled with salt or soy sauce, or use as a fish soup ingredient. The majority of consumers aged 20~29-years-of age preferred to wrap sashimi with perilla leaves. As a side dish, regardless of age, consumers preferred to pan-fried perilla leaves with mincedmeat and perilla leaves.

1,3-Dichloro-2-propanol(1,3-DCP), together with 3-monochloro-propane -1,2-diol(3-MCPD), is a well-known contaminant of acid-hydrolysed vegetable protein. 1,3-DCP has also been found to occur in a range of other foods and ingredients, most notable in soy sauce. The objective of the study was to determine the toxicity of the 1,3-DCP in the rat following oral administration for 13 weeks. (omitted)

This study was performed to predict the multiplication growth patterns of Salmonella typhimurium according to the holding methods and times in cooked foods served at foodservice institutions. When simmered pork in soy sauce and ham and cucumber salad were inoculated with S. typhimurium (7.00 logCFU/g) and tested according to holding methods and times, room temperature holding showed a continuous increase in S. typhimurium count as time passed, whereas 80$^{\circ}C$ heating table sharply reduced the count to 4.00 (logCFU/g) after 2hrs of holding and to zero after 6hrs, which suggested that all S. typhimurium were destroyed. However, 5$^{\circ}C$ refrigerator holding showed a count increase, although it wasis still lower than that at room temperature and at 10$^{\circ}C$ cold table holding, which suggested that S. typhimurium is comparatively resistive to low temperature.

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.
