  • This study was conducted to investigate the potential origin of Weissella species, which were found in ingredients of kimchi, such as salted Chinese cabbage, radish, green onion, red pepper powder, pickled shrimps, garlic, and ginger. Ten strains of Weissella species (Weissella thailandensis, W. kimchii, W. koreensis, W. minor, W. halotolerans, W. hellenica, W. kandleri, W. confusa, W. viridescens, and W. paramesenteroides) and lactic acid bacteria isolated from ingredients of kimchi were analyzed by SDS-PAGE of whole-cell proteins. Several strains with patterns identical to those of Weissella kimchii were isolated from green onion. On the basis of biochemical characteristics and 16S rDNA sequence comparisons, these strains were identified as Weissella kimchii, suggesting green onion as a major origin of Weissella kimchii found in kimchi.

  • A severe infection on pepper fruits by a black mold fungus was observed in the fields, Suweon. Conidia of Alternaria sp. were isolated from the infected fruits. Based on the morphological characters and size of the conidia, the fungus was identified as Alrernaria alternata (Fries) Keissler. The single spore isolates of A. alternata were weakly or not pathogenic on non-wounded pepper fruits, but highly virulent on fruits wounded with sandpaper or heated-glass rod. The infection on the wounded fruits were more severe on red fruits than on immature green ones. No visible infection was found on leaves and stems when 60-day-old plants of pepper were inoculated with the fungus. In July of 1984, the field losses of pepper fruits caused by black mold were $2.0\~22.5\%$ in Suweon.

  • Importance of climate change and its impact on agriculture and environment has increased with the rise Green House Gases (GHGs) concentration in the atmosphere. To slow down the speed of climate change many efforts have been applied in industrial sectors to reduce GHGs emission and to enhance carbon storage. In agricultural sector, many researches have been performed on GHGs emission reduction, but few on the role of carbon sink. In this study, we investigated carbon balance and soil carbon storage in agricultural field in the barley-red pepper and barley-soybean cropping system. With the system for automatic measuring of carbon dioxide, net ecosystem production(NEP) was estimated to be $6.3ton\;CO_2\;ha-1$ for N-P-K chemical fertilizer treatment plot and $10.6ton\;CO_2\;ha^{-1}$ for N-P-K chemical fertilizer with swine manure treatment plot in the barley-soybean rotation cropping. In the barley-red pepper rotation cropping, it was $12.0ton\;CO_2\;ha^{-1}$ for N-P-K chemical fertilizer treatment plot and $13.2ton\;CO_2\;ha^{-1}$ for N-P-K chemical fertilizer with swine manure treatment plot. Soil carbon storage rate was estimated to be $0.7ton\;C\;ha^{-1}$ for the barley-soybean cropping system and $0.5ton\;C\;ha^{-1}$ for barley-pepper cropping system. In appeared that agricultural lands may contribute to the greenhouse effect as a potential carbon sink preserving carbon into soil.

  • This study was reviewed the changes in main ingredients, seasonings and cooking methods of Tangpyeongchae in Korean cook books and literatures published from the 1700s to the 1960s. The first published books about Tangpyeongchae were in Kosasibijib and Kyongdojabji, written in 1783 and the late 1700s, respectively. Tangpyeongchae, a representative traditional Korean dish that was royal cuisine offered at ritual events in the Chosun Dynasty, was called Cheongpochae in the royal court. It was a dish made by mixing cheongpomuk (mung bean gel), meat, dropwort, mung bean sprout, egg strips and laver. This dish has been seasoned with vinegar, soy sauce, black pepper, garlic, green onion, red pepper, salt, sugar, sesame oil and sesame salt since the early 1900s. Dropwort, egg strips, laver, pine nut (powder), red pepper powder, and red pepper threads were used as garnishes. Tangpyeongchae was made by mixing cheongpomuk with other ingredients and seasonings until the late 1800s. Since the early 1900s Tangpyeongchae has been seasoned first with other ingredients and then mixed cheongpomuk.

  • Vegetables are liberally taken to enhance the mineral, vitamin, and rouphage value of the diet. And calcium is an essential mineral at all ages, although the daily requirement varies with physiological status of the individual. On the other hand, oxalic acid is an unwanted constituent of several clinical disorders. It is therefore necessary to take into account the calcium as well as the oxalic acid content of the various calcium, foods. Oxalic acid, calcium, calcium/oxalic acid ratio and available calcium have been determined in 31 kinds of the Korean common vegetables. The results are summarized as follows; 1. The highest content of oxalic acid has been recorded in Amaranth. spinach and beet. It is respectively 1,100mg%, 619mg%, 550mg% in fresh sample. It is comparatively high in Leek, leavels of perilla, Mugwort, Chyi-leaves, green red pepper, Burdock. 2. Many vegetables have been calculated as below 2.0 in the calcium/oxalic acid ratio. 3. Avaiable calciumis much in Malaolitoria, Lettuce, Green onion whole, Green garlic, Wild onion, Cabbage and Radish root. 4. A food calendar is suggested as a guide to the proper selection of food items for normal individuals and for those suffering from urolithiasis, cardiovascular disease or calcium deficiency status.

  • Each of 48 monoconidial isolates of Colletotrichum gloeosporioides Penz. obtained from diseased fruits of pepper was classified into strain G or strain R based upon pathogenicity to green and red fruits, morphology of conidia, and cultural characteristics in potato dextrose agar. The strain G was designated for isolates to cause anthracnose symptoms both on green and red fruits. All isolates of the strain G produced conidia abundantly. but produced no perithecia and setae in PDA. Conidia of all isolates in the strain G were attenuated or round at one end. The optimum temperature for mycelial growth of strain G was $26-28^{\circ}C$. The mycelia of strain G in PDA appeared to be whitish when young, and turned to be dark in old culture. Symptoms on pepper fruits caused by the strain G were somewhat sunken to be circular to elliptical lesions. Yellowish conidial masse were observed at the center of lesions, and the lesions turned to irregular shape and to reddish brown color in the later stage of disease development. No setae were visible on the acervuli. The strain R was designated for isolates to cause anthracnose symptoms only on red fruits of pepper. All isolates of the strain R produce conidia, and perithecia of Glomerella cingulata (Stonem.) Spauld. & v. Sch. in PDA. Some isolates of the strain R produced setae in culture under fluorescent light. Conidia of all isolates in the strain R were round and blunt at the ends. The optimum temperature for mycelial growth of strain R was the same as that of strain G. The mycelial growth of strain R was faster than that of strain G in PDA. The mycelia of strain R in PDA appeared to be gray to dark. Symptoms on pepper fruits caused by the strain R were circular to irregular black ring-spots Short setae or no setae were visible on the acervuli.

  • Organic farming in Korea has mainly focused on producing vegetables in plastic film house and cereals in paddy field. For high productivity of vegetables and cereals, most Korean farmers have not applied crop rotation in the cropping system. Thus, this study was carried out to evaluate the effects of crop rotation on the yield of red pepper and green onion, the changes in soil fertility and the potential as green manure of rye and hairy vetch. Rye and hairy vetch were cultivated for winter season every year, and directly incorporated into the soil. The yield of red pepper fruits in organic farming using crop rotation (OFCR) decreased 23 to 36% compared with conventional farming system (CFS). Whereas, green onion showed the increased yield of about 13%. In OFCR, total carbon content of soil was higher, however available phosphate content lower than conventional farming. As a result of measuring the bulk density of soil, OFCR and CFS were 1.26 to $1.35Mg/m^3$ and 1.37 to $1.42Mg/m^3$, respectively. Carbon and nitrogen contents of microbial biomass in OFCR were obviously higher compared with the CFS. In the plot cultivated rye for winter season, the weed germination was strongly reduced (about 52 %). Balance of macro nutrient elements, nitrogen and phosphate, in the application of rye and hairy vetch had a minus value. For potassium, the output value was higher than the input one, therefore organic farming under red pepper-rye or hairy vetch systems requires applying additional potassium input. Also, we selected two hairy vetch varieties of cv. Hungvillosa and Ostsaat which can be adapt at Korea climate. In order to estimate a yield of green manures, the weight of shoot and root was measured. The ratio of shoot and root between rye and hairy vetch showed 0.88 and 1.91, respectively. The potential levels of nitrogen, phosphate and potassium which could be supplied from rye were 7.7, 7.8 and 21.9 kg/10a and from hairy vetch were 17.0, 8.6 and 22.9 kg/10a, respectively. So we recommend that cultivating hairy vetch, as a nutrient supplier, and rye, as an amendment to enhance the soil physical property, for winter season be practical method in Korea organic farming system.

  • The Guk was divided Malgunjangguk, Tojangguk, and Gooumguk as to cooking method. Gooumguk was boiled with several materials of beef, bone, organs and water for the long time, and a good source of protein, calcium, and phosphorus. In the thesis, according to the kinds of Gooumguk, the reference frequency to them, the adding foods in them, and the variety cooking method in the Gooumguk were analyzed by the cooking books published from 1670 to 1988 in Korea. 1. There were 41 kinds of Gooumguk and Kaejang, Joktang and Byultang were firstly published to Omshikdimibang in 1670. 2. Many kinds of Gooumguk were generally used on royal parties in Yi dynasty and were used by several substances. 3. The main substances of Gooumguk were meat, poultry, fish, and shellfish. The seasoning substances were green onion, garlic, ginger and black pepper etc, and were used for the removal of the meat's or fish's off-flavor. 4. Yangtang, Kalbitang, Joktang, Yeongebacksuk, and Chooatang etc expressed the taste of the one main substance and Japtang, Sulnongtang, Yukgejang, Yongbongtang etc were combinated the taste of the several materials. 5. Cooking methods of Yukgaejang and Koritang before 19 century were different in present.: Yukgaejang was not used Gochoojang or powdered red pepper and Koritang was used Gochoojang.

  • The study was an attempt to compare the Korean home-made sesame oil (sample A) with the market goods in Korean (sample B) and in Japan (sample C) for their flavor and cooking after an hour heating. And there were 5 spices used green onion , garlic, ginger, black pepper and red pepper in heating process of the sesame oil. The results obtained were as follows : 1) On the chemical changes of AV, IV, SV, TBAV, and the appearence of color and viscosity , it was supposed that the changes were showed merely more by the heating than the heating of the spices addition. Among the spices garlic was noticed to change greatly in comparison with the other spices. And A was showed to change a little respectively at color , SV, which B, C changed more. 2) Through the sensory examination there was not of significant effect in the strength and acceptability after an hours heating between sample A, B and C. 3) Basic aroma component of the fresh sesame oil and the heating in the carbonyl fraction were analyzed and indentified by G L C. N-hexanal, n -heptanal , n-octanal etc were increased by means of the heating , sample b remarkably more than A.
