  • The main objective of the study was to investigate the phytic acid contents of various cereals and legumes produced in Korea. The results showed that the phytic acid contents of buckwheat, foxtail millets, sorghum, millet, barley, jobs' tears, yellow corn and wheat flour (Urimil) were in a range of 0.13 to 2.27%. The contents of the phytic acid ranged from 1.03 to 1.16% for legumes including red Indian bean, black Indian bean, mung bean, and black soybean. The phytic acid content of brown rice was five times higher than those of 100% polished rice. The polishing process of the rice decreased significantly the content of the phytic acid. We estimate that the daily phytic acid intake from rice was changed from 653 mg/day in 1995 to 430 mg/day in 2005 based on the results of a national nutrition survey.

  • 제빵용 밀가루인 강력분에 흑마늘 추출액을 0, 5, 10, 15% 첨가하여 반죽의 레올로지 특성으로 Falling number, RVA에 의한 호화 특성, Farinograph, Alveograph 등을 분석하였다. Falling number는 흑마늘 추출액의 첨가량이 증가함에 따라 대조구에 비하여 낮아졌으나 제빵적성의 범위에 있었다. 호화도 특성에서 흑마늘 추출액의 첨가량이 증가함에 따라 호화개시 온도, 최고점도, 유지강도, 최종점도, break down, set back 등 모두가 대조구에 비해 증가하였다. Farinograph 측정에서 흑마늘 추출액 첨가량이 증가할수록 반죽의 강도와 흡수율은 증가하였고, 반죽형성시간은 감소하였으며 안정도와 약화도는 급격히 감소하는 경향을 나타냈다. 반죽의 내성(MTI)은 대조구에 비해 흑마늘 추출액 첨가량이 증가할수록 증가하였으며, FQN은 대조구가 가장 높았다. Alveograph 측정에서 $P_{max}$는 대조구가 가장 높았고 L, G 값은 흑마늘 추출액 15% 첨가구가 가장 높았으며 W값은 15% 첨가구에서 가장 낮았다. 이상의 실험 결과 흑마늘 추출액 5%까지는 첨가가 가능하나 그 이상은 반죽의 레올로지 특성을 저하시켜 제빵 적성이 나빠질 것으로 생각된다.

  • As people know how to brew a wine from fruits and cereals, they continued to develope various wines good to their taste. Korean wines are also ones made from cereals and they have long been eager to improve the delicate taste. They used to drink Takju, raw rice wine, made from nonglutinous rice and Nuruk, a kind of yeast starter. During Koryo Dynasty, Soju a liquor was imported from Won(the Chinese dynasty). Nowadays this traditional folk wine, which had been developed variously and drunk all over the country, is decreasing year after year. The purpose of this study was to review on the wines ; its kinds, raw materials, brewing method, manufacturing utensils, measuring units and devices and the terms for wine making based on 20 documents published in 1600, in the middle of Yi dynesty. The results of review were as follows. 1. There were 121 kinds of wines at that time in Korea. 2. Among the raw materials for wines, major materials were glutinous rice, nonglutinous rice, wheat flour, wheat, mung bean, and black soybean. And minor materials were pepper corn, Lycium chinenisis, cinnamon, pine needles, pine nuts, jujube, mugwort leaves, lotus leaves, pine corn, pine bud, chrysanthemum, pine flowers, honey, Acanthopanox seoultenses, bamboo-root, marrowbone of blak cow, sweet flag, Ciprus noblis, Saurea lappa, honey suckle, Tricho santhes, azalea, the leaves of the paper mulberry, and bark of chungum tree. 3. There were several kinds of wines such as a wine without using Nuruk, a wine made from glutinous rice, nonglutinous rice, or glutinous and nonglutinous rice with flour. 4. There were several brewing methods for wines such as a wine boiled with ring rice cake, a wine brewed with loaves of rice cake, a wine brewed with hard boiled rice, a wine brewed with rice gruel, and a wine brewed with powdered rice gruel. 5. There were 23 kinds of utensils including measuring devices for weight and volume.

  • Black sooty mould fungus was observed on the upper side of the mulberry leaves caused by the Capnodium sp. This fungus develops with the utilization of the honeydew dropped by the whiteflies. Few selected insecticides like Monocrotophos, Chloropyriphos and Nuvan were tried to control the whitefly incidence and followed by the application of Maida (wheat flour paste) and Starch solution separately to control the incidence of the Capnodium on mulberry. It is found that a significant control of the whitefly incidence with the application of Nuvan (2 $m\ell$/L) and followed by Chloropyriphos (2 $m\ell$/L) and Monocrotophos (1.6 $m\ell$/L) and also a significant control of sooty mould infection were recorded with Starch and Maida application.

  • Rice consumption has been continuously decreasing as the eating habits of Koreans have become westernized and diversified. The per capita annual rice consumption in Korea has dropped sharply from 136.4 kg in 1970 to 61.9 kg in 2016. The Korean government, therefore, has been trying to promote rice consumption by invigorating the processed food industry using rice flour. To facilitate the market for processed rice foods, it is essential to develop proper milling technology in terms of flour particle size and damaged starch content to produce high quality rice flour at competitive cost. Dry milling and wet milling are the two major processes used to produce rice flour. Although the dry milling process is relatively simple with a lower production cost, damaged starch content increases because of the high grain hardness of rice. In wet milling, the quality of rice flour is improved by reducing flour particle size as well as damaged starch content through soaking procedures. However, the production costs are high because of the additional expenses associated with the disposal of waste water, sterilization and drying of the wet flour. Recently developed technologies such as jet milling and cryogenic milling also require expensive investment and production. Therefore, developing new rice cultivars with dry milling adaptability as well as good processing properties is an important goal of rice breeding in Korea. 'Suweon 542' is a floury endosperm mutant line derived from sodium azide treatment on a high-yield, early maturing, and non-glutinous japonica rice cultivar, 'Namil'. Compared with the wild type, after dry milling process, the grain hardness of 'Suweon 542' was significantly lower because of its round and loosely packed starch granules. Also, the flour of 'Suweon 542' had significantly smaller particles and less damaged starch than 'Namil' and other rice cultivars and its particle size distribution was similar to a commercial wheat cultivar. Recently, through collaborations with nine universities and food companies, a total of 21 kinds of processed prototypes, using the dry milling flour of 'Suweon 542', were evaluated. In the production of major rice processing products, there was no significant quality difference between the flours prepared by wet milling and dry milling. Although the amount of water added to the dough was slightly increased, it was confirmed that the recipe applying the wet flour could be used without significant change. To efficiently transfer the floury endosperm characteristics of 'Suweon 542' to other commercial rice cultivars, it is essential to develop DNA marker tightly linked to the target gene. Association analysis using 70 genome-wide SSR markers and 94 F2 plants derived from 'Suweon 542'/'Milyang 23' showed that markers on chromosome 5 explained a large portion of the variation in floury grains percentage (FGP). Further analysis with an increased number of SSR markers revealed that the floury endosperm of 'Suweon 542' was directed by a major recessive locus, flo7(t), located in the 19.33-19.86 Mbp region of chromosome 5, with RM18639 explaining 92.2% of FGP variation in the F2 population. Through further physical mapping, a co-segregate and co-dominant DNA marker with the locus, flo7(t) was successfully developed, by which, thereby, breeding efficiency of rice cultivars having proper dry milling adaptability with high yield potential or useful functional materials would be improved. 'Suweon 542' maintained the early maturity of the wild type, Namil, which can be used in rice-wheat double cropping systems in Korea not only for improved arable land but also for sharing flour production facilities. In addition to the high susceptibility against major rice diseases, nevertheless, another possible drawback of 'Suweon 542' is the high rate of viviparous under prolonged rainfall during the harvesting season. To overcome susceptibility and vivipary of 'Suweon 542', the progeny lines, derived from the crosses 'Suweon 542' and 'Jopyeong', an early maturing rice cultivar with multiple resistance against rice blast, bacterial blight, and rice strip virus, and 'Heugjinju', a anthocyanin pigment containing black rice cultivar, were intensively evaluated. As the outputs, three dry milling suitable rice elite lines, 'Jeonju614', 'Jeonju615', and 'Jeonju616' were developed.

  • The changes in ingredients, seasonings and cooking methods of Japchae in Korean cook books published from the 1600s to the 1960s were investigated in this study. Japchae was a royal dish enjoyed by Kwanhaegun of Joseon Dynasty and interesting historical story is contained in it. Kwanghaegun Ilgi in 1608 showed that Japchae was Kwanghaegun's favorite dish. Therefore, it has been thought that Japchae was created in the 17th century. Wonhaengeulmyojeongrieugye in 1796 described bellflower Japchae and mungbean sprout Japchae. The traditional Japchae was made without glass noodle called dangmyeon. Eumsikdimibang in 1670 first introduced traditional Japchae, which was made with 20 different ingredients and then served with topping sauce made of pheasant broth, strained soybean paste and wheat flour. Japchae in Kyugonyoram(1896) was prepared by mixing mungbean sprout, watercress, gonjasoni, tripe and yukhwe with mustard. The current style Japchae with glass noodle first appeared in the 1920s and became popular in the 1950s because the traditional Japchae was described in cook books until the 1940s. There were two ways of preparing current style Japchae. Yijogungjeongyoritonggo in 1957 described Japchae was made by mixing the boiled glass noodle with other ingredients and seasonings together. On the other hand, Japchae in Urinaraeumsikmandeuneunbeob(1960) was prepared by seasoning first with other ingredients, and then mixing boiled glass noodle. A variety of ingredients - vegetables, mushrooms, meat, fish, pheasant, beef tong, sea cucumber, gonjasoni and pear - has been used to prepare Japchae. Japchae has been seasoned with ginger, soy sauce, black pepper, sesame salt, sesame oil, oil, leek, garlic, salt, sugar, vinegar and mustard. Egg strips, pine nut, thin strips of Shiitake and stone mushroom, red pepper threads, Chinese pepper(cheoncho), black pepper and ginger were used for garnishing.
