본 연구는 시중에서 판매되는 메밀 제품 중 밀가루의 혼합여부를 판별하기 위한 가능성을 검토하기 위하여 시도되었다. 메밀은 통합분, 내층분, 중층분, 외층분으로 나누어 제분하였다. 모든 메밀분중 회분, 단백질, 지방함량은 외층분=통합분>중층분>내층분 순으로 높았다. 밀가루와 메밀외층분은 회분과 단백질함량에서 비슷한 수준을 보였다. 칼륨과 마그네슘 함량은 모든 메밀분이 밀가루에 비하여 높은 수준을 보였다. Quercetin 유도체인 플라보노이드 함량은 외층분>통합분=중층분>내층분 순으로 높았으나, 밀가루에서는 검출되지 않았다. 통합분과 밀가루의 혼합분의 비율과 마그네슘 또는 회분량과의 사이에 신뢰할만한 상관관계가 관찰되어, 이를 기준으로 시판제품 중 메밀함량을 평가하였다. 그러나 이 성분은 메밀의 제분정도 또는 원료에 따라 크게 변동될 수 있어 밀가루의 혼합을 확인할 수 있는 지표로 사용하기는 어려울 것으로 사료된다. This study was tried to evaluate possibilities for discriminating the mixture degree of wheat flour from buckwheat products. Buckwheat was milled into four grades of powder, i.e. whole grain flour(WGF), inner layer flour(ILF), middle layer flour(MLF) and outer layer flour(OLF)), and these powders were mixed with wheat flour(WF) to make mixed samples. Ash, protein and fat contents of the buckwheat flours were high in the order of OLF=WGF>MLF>ILF. On the other hand, WF showed a similar content to OLF in ash and protein, and to ILF in fats. Potassium and magnesium contents were higher in all the buckwheat powder than in the wheat flour. Flavonoid contents were higher in order of OLF>WGF=MLF>ILF, but it was not in wheat flour. Although the reliable correlation between mix ratio and components, i.e. mag-nesium or ash analyzed were found, it did not seem to reflect sufficiently the expected variations of contents of original material components. Also, compositions of commercial buckwheat products were analyzed to evaluate the mixed ratio of buckwheat flour and wheat flour. The results suggest that the components analyzed in this study as putative marker were not good in determining whether or how much buckwheat products contained wheat flour.

혈청 콜레스테롤과 3 - Hydroxy - 3 - Methylglutaryl Coenzyme A Reductase

최용순(Yong-Soon Choi),이상영(Sang-Young Lee) 한국식품영양과학회 1992 한국식품영양과학회지 Vol.21 No.5

Cholesterol have many essential functions as a component of cellular and subcellular membranes, metabolic precursor of bile acids and steroid hormones, and obligatory part of the metabolic systems involved in DNA synthesis and cell division. These essential funtions demand a continuous and appropriate supply of cholesterol to the tissues. Body cholesterol pool is maintained by the balance of acquirement from diets, de novo synthesis, and excretion either as bile acids or neutral steroids. In these metabolic process, cholesterol biosynthesis is controlled by the change in the activity of 3-hydroxy-3-methylglutaryl coenzyme A (HMG-CoA) reductase. Under most physiological or nutritional situations, the activity of this enzyme is adroitly regulated to maintain tissue cholesterol balance. Excess cholesterol accumulation in the cells induces the decrease in the number of LDL-receptor, followed by the increase in the level of serum LDL-cholesterol. Increase in the level of serum cholesterol appears to be an important determinant for the incidence of the coronary heart disease. Dietary intervention may be helpful in alleviating an increase in the level of serum cholesterol or body cholesterol pool.

최용순(Choi Yong-soon),강정석(Kang Jung-seok),박홍성(Park Hong-seong) 대한전기학회 2007 대한전기학회 학술대회 논문집 Vol.2007 No.10

UPnP Bridge supporting diverse network interface has to meet standard requirements in order to be connected with legacy devices. It is able to provide or bridge a service description and device description according to a specification because IEEE1394 and USB have this standard requirements. But it is difficult to know whether it RS232C supports only serial communication and packet transfer. It need a document for the standard definition of communication protocol on UPnP device having such interface. By doing so, this document can understand device and packet type. This paper defines MFD(Message Field Description) and makes UPnP message converter. So it will be base to standardize supporting variable legacy device.

인스탄트 메밀국수가 백서의 소화율, 성장율 및 조직내 지질함량에 미치는 효과를 검토할 목적으로 정제 사료에 탄수화물원으로서 설탕, 인스탄트 소맥면 및 메밀면 (소맥분중 10 및 30% 함유) 섭취군으로 4군으로 나누어 4주간 사육하였다. 체중증가량 및 식이섭취 량은 설탕섭취군보다 다른 3군에서 유의하게 높았으나, 실험군사이에 유의한 차이는 없었다. 본 연구에서 의식이 탄수화물원의 차이는 조소화율에 유의한 영향을 주지 않았다. 혈청 및 간장의 콜레스테롤 농도는 각 군간 유의한 차이는 관찰되지 않았다. 혈청 및 간장의 중성지질의 농도는 메밀면 섭취군에서 낮은 경향을 보였으나 유의한 차이는 없었다. 이러한 결과는 인스탄트(알파화) 메밀면(30% 함유)은 다른 주요 영양성분의 소화율에 장애를 주지 않으며, 완만하게 중성지질을 낮추는 효과가 있음을 시사한다. To evaluate a possible effects of instant buckwheat noodle on hepatic and serum lipids profiles, apparent digestibilities and growth rate, male young rats were fed diets containing sucrose as a control group, instant 100% wheat flour noodle, or instant wheat noodle fortified with either 10% or 30% buckwheat flour as experimental groups for 4 weeks. Weight gain and feed intake in the two buckwheat noodle fed groups were similar to those of the wheat flour fed groups. In addition, no significant differences were found in the apparent digestibilities among the groups experimented. There were no differences in the hepatic and serum cholesterol levels due to the diets. However, buckwheat noodle group showed a trend to decrease the liver and serum concentration of triacylglycerol, compared to the sucrose and 100% wheat flour groups. The addition of buckwheat flour to wheat flour up to 30% seemed to be effective in lowering the hepatic triacylglycerol level. After 10hr fasting, the serum glucose level of the buckwheat noodle group was similar to the levels of the other groups. The presented results indicate that instant noodle containing buckwheat at the level of 30% has a mild hypotriglyceridemic effects, and no adverse effects on the digestion of macronutrients in rats.

최용순(Yong-Soon Choi),곽인신(In-Shin Kwak),이정애(Jung-Ae Lee),이상영(Sang-Young Lee) 한국식품영양과학회 1999 한국식품영양과학회지 Vol.28 No.2

지금까지 보고된 한국인의 혈청콜레스테롤 농도 및 식이 콜레스테롤량에 대한 자료(선택된 논문(21편), 보고서)를 이용하여, 1962년부터 1995년까지 1995년을 기준으로 한국인의 인구를 표준화하여 이 인자들에 대한 연차적인 변화를 추정하였다. 1962년부터 1995년까지 혈청콜레스테롤 농도는 증가하는 경향을 보였으나, 통계적인 의미는 없었다. 이기간 동안 혈청콜레스테롤 농도의 상승폭은 60대 이상의 연령에서 높았으며, 성별 간 증가패턴에 차이는 없었다. 콜레스테롤 섭취는 시골에 비해 도시에서 높았으며, 지난 25년간 섭취량은 직선적으로 증가하였으며, 1995년 주요한 콜레스테롤 공급원은 계란(39.3%), 멸치(8.3%), 해산물(35.3%), 육류(13%) 등이었다. 이들 결과로부터 1995년을 기준으로 한국인의 평균 혈청콜레스테롤 농도는 178㎎/dl, 평균 식이 콜레스테롤 섭취량은 278㎎/day로 추정되었다. To estimate annual changes in age-adjusted mean of serum cholesterol and cholesterol intake in Korea during the past years, data from 21 literatures regarding for serum cholesterol level of Korean or National Nutrition Survey Reports from 1962 to 1995 were extracted for this study. Age-standardization for mean serum cholesterol level was adjusted being based on Korean population composition in 1995. Mean of Korean serum cholesterol level depicted an increasing tendency from 1962 to 1995. Magnitude of changes in mean of serum cholesterol was big in the age old groups over 60th decade, but sex difference in the pattern was not observed. The estimated mean cholesterol intake was higher in the urban population than those of rural′s and it increased linearly from 1969 to 1995. Major food sources for cholesterol were egg(39.3%), anchovy(8.3%), seafoods(35.2%) meat(13%) in 1995. From the results, it was estimated that mean serum cholesterol and daily cholesterol intake of Korean would be 178㎎/dl and 278㎎/day in 1995, respectively.

셀레늄의 영양생화학

Selenium (Se) obtained from dietary sources including cereals, grains and vegetables is an essential micronutrient for normal function of the body. Plants convert Se into selenomethionine and incorporate it into proteins in place of methionine, while higher animals synthesize selenoproteins containing selenocysteine. Excessive Se in the body is methylated stepwise to methylated selenium metabolites from selenide. Both inorganic and organic forms of selenium can be the nutritional sources in human, and they are transformed to selenide and then the amino acid selenocysteine attached to a specific tRNA<SUP>ser(sec)</SUP>. The selenocysteine (Sec) is incorporated into selenoprotein sequences by the UGA codon. The decoding of UGA as Sec requires specific mechanisms because UGA is normally read as a stop codon: cis -acting sequences in the mRNA (the sele-nocysteine insertion sequence, SECIS, within the 3’untranslated region) and trans -acting factors dedicated to Sec incorporation are required for incorporation of Sec during translation of selenoprotein mRNAs. Approxi-mately 25 selenoproteins have been identified in mammals. Several of these, including glutathione peroxidases, thioredoxin reductases and selenoprotein P, have been purified or cloned, allowing further characterization of their biological function. The antioxidant properties of selenoproteins help prevent cellular damage from free radicals which may contribute to the development of chronic disease such as cancer and heart disease. Other selenoproteins have important roles in regulation of thyroid function and play a role in the immune system. Daily selenium intake was reported to be 42.0±16.9 ㎍/day in Korean adult women. This review focuses on the metabolism and biological functions of selenium, and the nutritional status of selenium in the Korean population.

메밀은 이차적인 식량자원으로 중요성을 갖는 곡물이다. 본 연구에서는 메밀의 영양적 기능성과 관련된 기전을 in vitro조건에서 평가하였다. 메밀은 메탄올 또는 물로 추출하였다. 물추출물은 이어서 효소로 처리한 후 얻어진 단백질가수분해물을 pH에 따라 분리하여, 각 추출물에 대하여 생리활성을 측정하였다. Fe^(2+)-ascorbic acid계에서 측정한 메탄올추출물의 항산화능력은 메밀품종에 따라 차이를 보였으며, 수원 4호 추출물의 경우 ascorbic acid의 3.3배(IC_(50))의 높은 항산화효과를 보였다. 또한, 메탄올추출물은 α-amylase와 aldose reducase활성을 저해하였다. 메밀단백질 또는 rutin은 angiotensin-converting enzyme활성을 저해하였으나, 가수분해물에 따라 저해정도는 차이를 보였다. 메밀단백질은 casein보다 높은 소수도를 나타냈으며, in vitro에서 산성스테롤과 결합능력을 보였다. 종합적으로 이러한 작용을 나타내는 메밀성분은 메밀의 혈당 혹은 이와 관련한 질병의 제어, 고혈압의 예방 나아가 혈청콜레스테롤저하를 유도하는 대사계의 주요한 조절인자로 보여진다. Generally, buckwheat has been regarded as a crop of secondary importance in many countries. In vitro functionalities of buckwheats as a food were evaluated in this study. Five of buckwheat cultivars were extracted with methanol, and the extractant were dried and lyophilized, separately. Or water soluble buck- wheat components were digested with the commercial enzymes and the obtained protein hydrolysate was again fractionated by acid precipitation. The antioxidant capacity of the methanol extracts determined using Fe^(2+) -ascorbic acid system was dependent on the cultivars: The extract of Suwon 4 showed 3.3 times stronger activity than ascorbic acid in terms of IC_(50). Also, the extracts of buckwheats inhibited efficiently the activities of α-amylase and lens aldose reductase. Buckwheat soluble protein or rutin suppressed the in vitro activities of angiotensin-converting enzyme, and the inhibitory degree depended largely on the cultivars. Buckwheat proteins exerted higher hydrophobicity being related to the sterol binding capacity than casein. The results suggested that buckwheat seeds may be desirable and functional food resources in human living in current society.
