  • The quality of the buckwheat bread made with previously heated ($55^{\circ}C$) and cooled buckwheat flour 0dough with the addition of ascorbic acid(AA) or/and sodium stearoyl lactylate(SSL) was evaluated . With heat treatemtn , handling property of dough and grain of the bread crumb were markedly improved and stickiness of the dough decreased . The optimum resting time to produce the best loaf volume and grain was found to be 3hr for both unheated and heated doughs. Heat treated dough showed higher dough expansion rate during fermentation than unheated dough, even though heated dough had lower loaf volume, probably because of an improper oven spring. Increase in shortening of dough formula from 3% to 5% improved loaf volume without improvement of handling property. With the addition of 100 ppm AA or/and 0.5% SSL, loaf volume and crumb grain were improved for both unheated and heated doughs.Microscopic analysis of a mixed dough by scanning electron microscope (SEM) showed that heated dough had a continuous network whereas unheated dough was discontinuous. The addition of AA and SSL gave the dough a more continuous network whereas unheated dough was discontinuous . The addition of AA and SSL gave the dough a more continuous structure with strengthened strands or interactions between the starch granule and protein. Therefore, it appears that the presence of continuity in heated buckwheat breadwheat bread dough is related to the improved loaf volume and crumb grain without dough stickness.

  • 전분의 어떤 성질이 묵 형성을 영향을 주는가를 알기위해 도토리, 메밀, 녹두 전분(묵전분)과 옥수수, 쌀, 밀 전분(비묵전분)의 이화학적, 분자구조적 성질과 전분지방질의 함량을 조사하여 겔 강도와 비교하였다. 전분의 아밀로오스 함량은 녹두, 도토리, 메밀, 밀, 옥수수, 쌀 순이었으며 겔 강도 역시 같은 순서로 나타나 이들 사이에서 가장 좋은 상관관계를 보였다(r=0.95). 묵전분의 아밀로오스의 특성을 보면 비묵전분보다 분자크기가 켰고(${\overline}D.P._{n}=1,800{\sim}1,580\;vs\;670{\sim}1,120$), 평균 가지수가 많았으나(${\overline}N.C.=2.9{\sim}5.4\;vs\;1.7{\sim}2.5$), 평균 가지 길이는 작았다(${\overline}C.L.=290{\sim}390\;vs\;390{\sim}450$). 묵전분의 아필로펙틴의 ${\overline}C.L.$은 비묵전분보다 컸으며 ($22.2{\sim}22.6\;vs\;18.9{\sim}21.3$), 전분지방질의 함량은 비묵전분보다 더 작았다($0.12{\sim}0.49\;vs\;0.68{\sim}1.26%$), 이들 분획물의 성질과 지방질함량은 겔 강도와 좋은 상관관계($r=0.76{\sim}0.84$)를 보였다. 따라서, 묵전분의 겔 형성능력은 아밀로오스 함량과 전분의 여러 특성이 종합적으로 작용해 나타내는 것으로 보인다.

  • The validity of the energy data of the starch-foods and seaweeds in Korean food composition tables has been suspected due to possible differences in their chemical compositions from those of western food ingredients. Energy conversion parameters being used currently in nutrition has been derived in countries where food items re quite different from ours. This study was undertaken to determine the metabolizable energy of starch-foods and seaweeds by the method selected in preexperiment20). Cooked starch foods and seaweeds were freeze-dried and fed to Sprague Dawley rat with 200∼300g body weight to measure apparent metabolizable energy (AME) values and nitrogen-corrected AME (AMEn) values for four days after three days of preliminary period for adaptation to the diets. The AME and AMEn values of the wheat noodle were 4554.6, 4584.7, the Starch Vermicelli, 3763.4, 3855.7, the Ra myon, 4916.9, 4876.0, the Buckwheat noodle, 4469.7, 4442.0kcal/kg dry matter, the Potato, 4514.6, 4520.0 and those of the Bread, 3256.9, 3582.6, 3260.5, kcal/kg dry matter, respectively. Those of Sea tangle were 1437.3, 1631.3 and of Laver, 3126.6, 3171.3kcal/kg dry matter, resectively. When the AME values of the starch-foods and seaweeds measureed in present study were compared with energy values calculated by various conversion parameters such as Atwater's Rubner's, Sochun's and FAO's, there appeared dramatic differences indicating that for many of the food items, the latter energy values by conversion factors are hardly acceptable. These data also suggest that the existing energy conversion factors are not applicable to seaweeds and a further study is needed to obtain specific factors for the conversion to biological energy from the chemical composition of seaweeds.

  • This study investigated the microbiological hazards in the manufacturing processes of Naengmyeon. Sanitary indicative bacteria, such as aerobic plate counts and coliforms as well as pathogenic bacteria, were examined from raw materials, manufacturing processes, working area, 17 utensils and equipment. The aerobic plate counts for raw materials and arrowroot starch estimated as 0.77±0.68~5.02±0.28 and 5.02±0.28 log CFU/g, respectively. Coliforms were detected from wheat flour, buckwheat flour, and potato starch. Staphylococcus aureus was detected to be 0.61±1.06 log CFU/g in wheat flour and 0.20±0.35 log CFU/g in buckwheat flour. During the manufacturing process, aerobic plate counts for kneading process were 4.54±0.34 log CFU/g. But after the press out and heat process, contamination of aerobic plate counts and coliforms decreased and remained at a low level until the release process. Aerobic plate counts before washing disinfection of screw were 3.28±0.62 log CFU/100 cm2, the level of which was high in utensils and equipment that had contact with employees or water. These results represent not only an important indicator for the hygienic level but also a scientific basis for analyzing biological hazards, which lead to the introduction of HACCP for the production of safe and hygienic cold noodles processed by manufacturers.

  • 묵의 형성과 그의 물리적 특성을 구명하기 위하여 동두전분을 포함한 9가지 전분의 겔 텍스쳐를 비교 분석하였고, 아밀로오스와 아밀로펙틴이 묵의 특성에 미치는 영향에 대하여 시험하였다. 10%의 전분으로 제조한 동부, 녹두, 도토리 및 메밀 전분 겔의 겔 지표는 2.11-2.37 범위로서 이들 상호간에 유의한 차이가 없었고, 탄성 한계는 0.60이상이었다. 겔 강도 계수는 녹두 전분 겔이 1400으로서 가장 높았고, 동부, 도토리, 메밀 전분 겔은 약 700-1000범위에서 상호간에 유의한 차이가 없었으며, 절단성은 동부 전분 겔은 0.23이었고, 다른 전분 겔들은 0.46-0.62범위였다. 묵의 텍스쳐 특성에 있어서 아밀로펙틴은 겔 지표와 탄성한계에, 아밀로오스는 겔 강도 계수와 절단성에 기여하며, 이 두 분획은 어느 한 쪽 만으로는 묵을 형성할 수 없고 두 분획이 알맞은 비율로 배합되어 있을 때 비로소 묵이 될 수 있다는 것을 알 수 있었다. 또한 곡류와 감자 전분으로부터 분리한 아밀로오스를 동부 전분이나 동부 아밀로펙틴에 첨가하면 그 효과가 다르게 나타났으며, 곡류 전분에 동부 아밀로오스를 첨가하면 겔 강도 계수와 절단성은 증가되었지만 겔 지표와 탄성 한계는 향상되지 않았다. 그러나 감자 전분은 동부 아밀로오스의 첨가에 의하여 겔 강도 계수가 증가되고 절단성이 생김으로써 묵과 비슷한 텍스쳐 특성치를 나타냈다.

  • Muck (Korean traditional starch jelly) is very unique and the one of the oldest starch processing traditional food. The typical ingredients for making muck such as acorns, mungbean and buckwheat have been eaten since the new stone age or even before that era. This study was for investigation on the history of muck and its processing methods in the ancient and the modern culinary literatures from the 1400’s to 1900’s. The summary of the reviews was as follows. In the ages from the 1400’s to 1700’s, using starch powder, Se-myon and Chang-myon were made and their shape were like noodles instead of cubical shape. It was after the 1700’s that muck making methods were revealed in the literature, like ${\ulcorner}Gyeong-do-jabji{\lrcorner}$ (1730) and${\ulcorner}Go-sa-sib-e-jib{\lrcorner}$ (1737). The naming of muck might be from the time after 1800’s, in${\ulcorner}Myoung-mul-kiryak {\lrcorner}$ (around 1870) the basis of the names of Choeng-po (white mungbean jelly) and Whang-po (yellow mungbean jelly) could be found. One of the most well-known muck dish, Tang-pyeong-chae, was recorded many old literatures, so it was found that Tang-pyeong-chae was very popular and governmental policy of Tang-pyeong-chak influenced the food of the common people. In ${\ulcorner}Shi-eui-jeon-seo{\lrcorner}$ (late 1800’s) there were records of several types of muck and starch powder making methods in detail which were handed down to the modern ages.

  • Among all the ingredients usedin mandu, the following types were used:, 13 types of grains were used (12.38%), 30 types of vegetables, fruits, bulbs,and nuts were used (28.57%), 32 types of marine products, birds, meats, fishes, and shellfishes were used (30.48%), 10 types of functional ingredients were used (9.52%) and. For spices, 20 types of spices were used (19.05%). 2. Cooking Methods offor Mandu. The mMandu eaten at in the early Joseon era had was primarily made ofusedbuckwheat that contained boiled tofu or egg uiijuk in the kneaded dough for the most part and while kneading with buckwheat, the tofu or egg uiijuk has been boiled down to knead the dough, and and starch powder, bean powder, or rice powder, etc were mixed to make the mandu coating. Buckwheat powder was mixed toadded to the flourwer or was used by itself, while meat, vegetables, tofu, and shiitake mushroom, etc were also addedincluded. From the 18th century, the host plant, or cabbage kimchi, were prepared and combined had been sliced to be used as filling together while red pepper powder was mixed combined withto spices or vinegar soy sauce to be used together. Also, Radishes had beenwere also used as filling, but shown as not being used fromafter the start of the 1900's. For the shape of mMandu, it was madeinto different shapes such as as triangle, rectangle, date plum, gwebul, half moon, or pomegranate shapes, and then shapes to be boiled in simmering water, baked, or cooked as soup in clear broth for soup., In the 17th to 18th century, boilingthen in a steamer gradually became a cooking style, assumed the style of boiling in a steamer in $17th{\sim}18th$ century while in the 16th century,the an essay ofn fermenting flour in ‘Food Dimibang’ in 16th century had indicated it was cooked as the style ofby steaming in a rice steamer. Also, Mandu may have also contained the following: the thin-cut and boiled fish was cut out thin to put into the filling and boiled down, made by putting in added pine nuts after making bbeef jerky or boiled- down meat, fish, or shellfish itself to extractsand mold mandu only the ingredients combined withto put on starch powder, and then boiled down and put on pine nut powder finally, after it or cooled it wasdown to be eaten by dipping in vinegar soy sauce. In conclusion, many different types of mandu were made during the Joseon era using a variety ofwhile the ones using such various ingredients. are also one type of mandu.
