전통 메주로부터 protease를 생성하는 곰팡이를 분리한 후, 이를 사용하여 메주를 만들고, 자연 발효 하여 메주를 만든 것을 대조구로 하여 된장을 제조하고 90일간 숙성시키면서 각 된장의 효소력과 환원당 함량 그리고 아미노태 질소와 암모니아태 질소량을 측정하여 첨가한 곰팡이가 된장의 품질에 미치는 영향을 조사하였다. 수분 함량은 숙성기간이 증가하면서 감소하는 경향을 보였으며, 시료별 수분 함량의 차이는 크지 않았다. 효소력 측정 결과, amylase 활성은 모든 시료에서 낮은 활성을 보였으며, 숙성이 진행되면서 계속적인 감소세를 보였다. Protease 활성은 분리 곰팡이를 사용한 된장이 대조구보다 높았으며 속성 30-45 일경에 최대치를 보이다가 그 이후 감소하는 경향을 나타내었다. Lipase 활성은 대조구와 시험구 된장에서 차이가 거의 없었고, 숙성 30일경에 최대 활성을 보이다가 그 이후 계속적으로 감소하였다. 환원당 함량은 숙성이 진행되면서 감소하였다. 아미노태 질소함량은 분리한 곰팡이를 사용하여 제조한 된장이 대조구보다 높았으며, 숙성이 진행되면서 계속적인 증가세를 보였다. 모든 시료의 에탄올 추출물에서 항산화력이 있음이 확인되었다.

Antimutagenic effects of 5 kinds of kochujang(Korean red pepper soybean paste) samples compared with doenjang(Korean soy paste) were studied using the Ames test with Salmonella typhimurium TA100 and the SOS chromotest, with E. Coli PQ37. Th eantimutatenic effects of methanol extracts from red pepper powder and meju(fermented soybean) powder, the major ingredients of the kochujang,were also evaluated for the mutagenicity of aflatoxin B1 (AFB1) in the Ames assay. The methanol extracts from the kochujang samples showed lower antimutagenicities than those of doenjang against AFB1 and N-methyl-N'-nitro-N-nitrosoguanidine (MNNG) in the Ames assay. Traditional kochujang I and II exhibited strong antimutagenic activity against AFB1 and MNNG. The traditional kochujang samples against MNNG were aslo observed in the SOS chromotest system with the same fashions as shown in the Ames mutagenicity test. The methanol extracts from meju powder had the strongest inhibitory effects on mutabenicity induced by AFB1, however, those form red pepper powder showed lower inhibition rate than kochujang. These results suggest that traditional kochujang exhibit higher antimutagenic acitivity than the commercial variety, and that meju powder seems to be one of the major antimutagenic components in kochujang.

Traditional screen printing is still a dominant method to print electrodes on c-Si solar cells. In order to achieve higher efficiency for c-Si solar cells, improvement of the electrode material is one of the key approaches. Shadowing loss can be reduced by using high aspect ratio finger electrode with width of finger electrode less than 80um. The rheological properties of Ag paste for applying c-Si solar cells are improved by using Ag nanowires. The printing properties including the aspect ratio of printed electrode can be improved with higher Thixotropic index (T.I.) values.

This study was conducted to investigate the physicochemical characteristics of Sunchang traditional kochujang(fermented hot pepper-soy bean paste) for quality standardization. The kochujang samples, which have been fermented for 8 months in 1999, were collected from 20 firms at folk village in Sunchang area and analyzed their chemical compositions and color reference. The mean value of moisture, amino-type nitrogen, pH, acidity and salt content of the samples collected were $44.62{\pm}1.79%$, $132.66{\pm}21.67\;mg%$, $4.52{\pm}0.08$, $15.77{\pm}1.62$ and $8.76{\pm}1.55%$, respectively. The moisture, pH, acidity and salt content of each sample did not show much differences among samples. The Hunter values(L, a and b) of Sunchang traditional kochujang were $25.72{\pm}1.58$, $23.26{\pm}1.71$ and $9.86{\pm}0.94$, respectively. The mean content of amino-type nitrogen of Sunchang traditional kochujang was $132.66{\pm}21.67\;mg%$, and there were a little difference between the minimum(100.33 mg%) and the maximum(164.56 mg%). The main free sugars of Sunchang traditional kochujang were fructose($1.86{\pm}1.01%$), dextrose($4.29{\pm}2.06%$), sucrose($0.54{\pm}1.21%$), and maltose($1.48{\pm}0.77%$). The contents of fructose, dextrose, and maltose had little difference among samples. The fatty acids in Sunchang traditional kochujang were composed of palmitic, stearic, oleic, linoleic, linolenic, octadecatetraenoic, arachidonic and behenic acid. The linoleic acid(18:2) showed the highest, occuping 59.37% of the total fatty acids.

The purpose of this study is to investigate the patterns of Korean traditional food use in the households of middle aged women living in Kyunggido and Incheon area Four hundred eighty seven housewives whose children were in middle school answered the questionnaire about Korean traditional food use patterns in ordinary days, national festive days and in private celebration or memorial days. Most households have used Korean traditional table setting called Bansang as daily meals(96.7%) and have used home-made Kimchi(97.3%). However, the use of home-made Jang such as soy sauce, soybean paste and red pepper soybean paste was not very high(64.3%). Most households have celebrated New Years day(99.6%) with Ddukguk and Manduguk, Chusuk(95.1%) with Songpyun, and fruits, Full-Moon day(95.1%) with Ogokbap, Namul and Brum. Dongji was celebrated with Patjug by 73.3% of households. However, Samjitnal and Danho were celebrated with Whajeon and Ssukjulpyun by only 18.9% and 43.8% of the households respectively. The households using Korean traditional food to celebrate the birthday, the 1st birthday of child, the wedding or to memorize the passing day of ancestors were 96.0%, 80.7%, 81.3% and 86.7% respectively. Compared to households of urban and nuclear family, households of rural and extended family tended to use significantly more Korean traditional foods in many occasions and showed significantly higher rate of using home-made Kimchi and Jang.

전통발효식품(간장 및 된장, 고추장, 감식초 등)중에 재래식과 개량식 제품의 맛과 향에 기인하는 유기산의 분포정도를 확인하고자 하였고, 아울러 식품공전에 보존료로 고시되어 있는 propionic acid가 발효과정 중에 생성됨에 따라 그 분포정도를 알고자 하였다 재래식 간장에서는 citric acid, formic acid, oxalic acid, propionic acid가, 개량식에서는 acetic acid와 lactic acid가 상대적으로 많이 검출되었으며, propionic acid는 검출되지 않았다. 재래식 및 개량식 된장 모두 유사한 분포양상을 보였으며, 재래식에서는 개량식 보다 citric acid와 succinic acid를 제외하고 약간 높은 함량을 보였다. 고추장의 경우 재래식이 개량식보다 citric acid, formic acid, acetic acid, lactic acid가 다소 높은 함량을 보였고, 그 외 다른 유기산들은 비슷한 양상을 보였다. 그러나 재래식에서는 Propionic acid가 검출된 반면 개량식에서는 전혀 검출되지 않았다. 일반 양조식초에서는 acetic acid가 주요 유기산이었고 미량의 formic acid가 검출되었으며, 감식초의 경우 acetic acid, lactic acid, propionic acid가 검 출되었다. 감식초중 flavonoid계 인 tannic acid 함량은 다소 제품별로 차이는 있었으나 그 범위는 366.9 ∼ 909.8 mg%를 보였다. 결론적으로 재래식 발효식품과 개량식 발효식품의 유기산 분포는 그 함량이 서로 달랐으며, 특히 보존료로 사용되고 있는 propionic acid는 된장을 제외한 재래식 발효식품에서 생성되었고, 개량식 발효식품에서는 생성되지 않았다. 또한 식초의 경우 감식초에서만 검출되었다.
