Legumes are important agricultural and commercial crops characterized by root nodules formed as a result of the symbiotic relationship with nitrogen-fixing rhizobia. Due to the economic significance the chemistry of some of these species has been well recognized. Soybeans and processed soy products, which contain isoflavonoids and saponins, are of wide interest for their multifacted biological effects. (omitted)

본 연구는 시판 장류의 알코올 함유량 및 관련 품질특성을 파악하고자 산도, pH, 염도, 환원당, 알코올 함량 및 효모수를 조사하였다. 산도는 재래식 된장과 간장이 개량식보다 낮게 나타났고, 재래식 고추장이 개량식보다 높게 나타났으며, pH는 재래식 된장과 고추장이 개량식보다 낮게 나타났고, 재래식 간장이 개량식보다 높게 나타났다. 염도는 재래식 장이 개량식 장보다 모두 높게 나타났고, 환원당과 알코올은 재래식 장이 개량식 장보다 모두 낮게 나타났다. 또한 주정 무첨가된 시료 중 알코올이 검출된 장류 중에 효모수를 측정한 결과 검출 유무가 알코올 함량과 연관성이 없어 효모의 존재만으로 알코올을 생성하였다고 판단할 수 없었다. 지금까지 결과를 종합해보면 개량식 된장에 비해 낮은 환원당을 나타낸 재래식 된장의 경우 알코올 발효의 기질로 사용될 당이 부족하기 때문에 낮은 알코올 값을 보인 것으로 사료되고, 개량식 간장의 경우 재래식 간장보다 낮은 염도를 나타내기 때문에 균의 활동이 비교적 활발하여 산도와 알코올 함량이 높은 것으로 사료된다. 할랄식품 시장 진출을 위한 알코올을 함유하지 않은 장을 만들기 위해서는 난분해성 당을 사용하고 염도를 높여 균 활동을 억제하는 추가적인 연구가 필요할 것으로 보인다.

The Internet, as a commercial tool, provided a new market that connects producers to consumers through I-commerce. 2-commerce through the Internet became a new trend in all industries. This research indicates problems that block the activation of I-commerce of agricultural products, which is less developed than the other industries. To solve the problems it suggests E-commerce for agricultural products combining on and off line markets. It also suggests data mining technique for analyzing entire information in system.

Deonjang has been developed as a fermented food in Korea. It produces a distinctive flavors and tastes during the fermentation process. The purpose of this study was to determine the quality characteristics of commercial deonjang certified for traditional foods. We investigated the amino nitrogen, sodium chloride(NaCl), total colony counts, coliforms, Bacillus cereus and isoflavone of 24 commercial deonjang samples certified for traditioinal foods. Deonjang showed wide ranges in amino nitrogen(105.76~318.93 mg%) and NaCl(12.53~16.51%). Survey distribution of microflora investigation in the total colony counts were detected in all 24 samples(100%), and the range is low $1.5{\times}10^6$ CFU/g, at the highest $2.5{\times}10^9$ CFU/g respectively. For the coliform, the following results were $0{\sim}5.0{\times}10^1$ CFU/g. B.cereus was detected in a total of four samples were $2.5{\times}10^3{\sim}3.3{\times}10^4$ CFU/g in the distribution. Daidzein of isoflavones showed the lowest at 86.7 ppm, 681.8 ppm range of the best shows and genistein as low as 0 to 50.0 ppm respectively. This research provided information for quality characteristics of commercial deonjang certified for traditional foods.

우리 국민의 주식이 되는 쌀(백미)과 콩류, 감귤류, 열대과 일류, 엽채류, 엽경채류, 근채류, 과채류, 버섯류에 속하는 농산물(989건)에 대해 8종의 EBI계 농약의 잔류 여부를 분석하였다. 그 결과 8건의 검체에서 농약이 검출되었고 농약 수는 5종이 검출되었다. 기준 미설정 농약은 2종이었으며, 곡류 134건 중 4건 검출로 3.0%, 채소류 471건 중 4건 검출로 0.8%의 검출율을 나타내었다. 그 외 콩류(48건), 견과종실류(72건), 과실류(197건), 버섯류(67건)에서는 전혀 검출되지 않았으며 부적합율은 0.1%로 나타났다. 국내 미등록농약인 paclobutrazole이 근대에서 잠정허용기준을 초과하는 것으로 확인되었다. 그리고 EBI계의 검출율은 0.8%로 매우 낮았으며 검출된 농약의 경우도 기준규격 이하로 안전한 수준이었다.

Content analysis of flavonoids (epicatechin, epicatechin gallate, and rutin) present in the leaves of Boehmeria nivea (originating from Geumsan-myeon, Biin-myeon, Hansan-myeon, and Baeksu-eup) and their commercial products (ramie tteok, ramie songpyeon, ramie bory-tteok, and ramie tea) was conducted by HPLC. The content of epicatechin, epicatechin gallate, and rutin was highest in the leaves of B. nivea from Geumsan-myeon (0.138 mg/g), Baeksu-eup (1.654 mg/g) and Geumsan-myeon (12.205 mg/g), respectively. With respect to commercial products, the content of epicatechin and epicatechin gallate was highest in ramie tea, with concentrations of 1.879 and 1.090 mg/g, respectively. Given these flavonoid concentrations, B. nivea leaf extracts have the potential to be used as additives in natural medicinal products, health supplements, and beverages.

This study was conducted to examine the physicochemical properties and consumer acceptability of commercial Gang-jeong. The samples used in this study were nine different Gang-jeong as commercial products. To accomplish this research, the physicochemical properties of nine samples, including moisture, crude lipid, sugar contents, acid value, color values, and texture, were measured. In addition, consumer panels evaluated the overall acceptability, appearance, flavor, sweetness, and texture of samples using a 9-point Likert type scale as well as the perceived intensities of sweetness and rancid odor by a 9-point Just-About-Right (JAR) scale. All data were statistically analyzed using One-way ANOVA, Principle Component Analysis, Hierarchical Cluster Analysis, and Pearson's Correlation Analysis. All physicochemical properties were significantly different among the samples (p<0.001). Analyses of consumer acceptability and JAR ratings of the nine samples showed significant differences (p<0.001).

This study was performed to analyze the JAR (Just-About-Right) Rating and CATA (Check-All-That-Apply) Method for commercial Yugwa (Korean oil pastry products) containing Baeknyeoncho (Opuntia ficus-indica var. saboten). The survey was conducted with 50 participants, and five kinds of Yugwa samples (Control, B-YG, B-RY, B-WY and B-GB) were used. According to the results of the study with these samples, the B-RY sample received the highest score in 'Try again (6.30/9)' and 'Recommend (6.24/9)'. The Control Sample, which was the traditional Yugwa, received the second highest score (Try again: 5.62/9, Recommend: 5.70/9). The liking attributes for these samples were related to eating convenience, familiar taste, traditional type and size. These findings suggest that the factors to be considered in the development of commercial Yugwa are the maintenance of traditional taste and familiarity in an easy-to-eat size for consumers.

This study was carried out to investigate the 106 kinds of pesticide residues in agricultural products (n=3,614) by GC, for the northern area of Seoul from March (1999) to December (2000). The detection rate of pesticide residues in samples was 5.0% (mean =2.86$\pm$7.22 mg/kg, n=180). The order of the agricultural products in which pesticide residues were detected was korean lettuce > perilla leaf, pepper > chinese cabbage > leek > spinach. The percentage of the agricultural products in excess of MRL was 2.0% (n=73). The agricultural products in excess of MRL were korean lettuce (n=15), perilla leaf(n=13), leek (n=6), spinach (n=6), pepper (n=5), chwinamul (n=5), etc. The order of the pesticide residues which were detected in agricultural products was procymidone endosulfan chlorpyrifos vinclozolin chlorothalonil and diazinon. The average residual values of procymidone, endosulfan, chlorpyrifos, vinclozolin, chlorpyrifos, and diazinon were 4.07, 1.24, 1.27, 2.83, 17.71 and 1.48 respectively. The pesticide residues in excess of MRL were chlorpyrifos (n=19), endosulfan (n=12), procymidone(n=), vinclozolin (n=6), etc, and the measured concentration ranges of chlorpyrifos, endosulfan, procymidone, vinclozolin, pyrazophos, diazinon and EPN were 0.03-6.72, 0.18-5.8, 2.0-60.8, 1.70-20.33, 0.26-1.21. 0.59-4.3 and 0.28-4.19 respectively.
