  • 6개월 숙성된 재래식 고추장과 시판 중인 공장산 고추장의 이화학적 특성을 비교하였다. 공시된 고추장은 순창지역의 찹쌀고추장 18종, 보은지역의 10종의 보리고추장, 사천 지역의 밀 고추장 17종 및 공장산 고추장 10종이었다. 재래식 고추장의 유리당 함량은 대체로 공장산 고추장의 1/4 수준이었으며 주요 유리당은 glucose로 나타났고 이밖에 fructose, maltose sucrose가 검출되었다. 유리아미노산의 총량을 비교해 보면 공장산이 1,089mg으로 가장 높았고 그 다음이 사천, 순창, 보은 고추장 순으로 각각 554, 498, 266mg이었다. 각 고추장에서 가장 많이 함유되어 있는 유리아미노산은 순창 고추장에서는 serine, 보은 및 사천고추장에서는 aspartic acid, 공장산 고추장에서는 glutamic acid로 나타났다. 재래식 고추장에서 발견되는 휘발성 유기산으로는 acetic aicd, propionic acid, butyric acid 및 3-methyl butanoic acid가 검출되었으나, 공장산 고추장에서는 이 중 3-methyl butanoic acid가 검출되지 않았다. 함량면에서 aceticacid가 가장 많은 유기산으로 나타났으며 재래식 고추장에서 함량상 중요한 비휘발성 유기산은 lartic, oxalic, succinic acid이며 공장산 고추장에서는 이외에 itaconic, malic, malonic, pyroglutamic acid가 미량 검출되었다.

  • The volatile flavor components of traditional and commercial kochujang were collected by simultaneous steam distillation-extraction (SDE) method. Essential oils were analyzed by gas chromatography (GC) and combined gas chromatography-mass spectrometry (GC/MS). Tested kochujang included Sunchang kochujang prepared with glutinous rice, Boeun kochujang prepared with barley, Sachun kochujang prepared with wheat and commercial kochujang. One hundred and twelve volatile flavor components which included 30 esters, 15 alcohols, 14 aldehydes, 13 acids, 9 ketones, 7 alkenes, 6 phenols, 3 alkanes, 3 pyrazines, 2 benzenes and 2 furans were identified. The major volatile compounds in traditional and commercial kochujang were 2-methyl propanal and ethanol, which represented $21{\sim}36%\;and\;2{\sim}44%$ of total GC peak area, respectively.

  • Consumption and general views of housewives in Inchon on commercial kochujang(fermented red pepper-soy paste) were surveyed by questionnaires in June through August, 1997. Respondents considered the taste (88.1%) as the most important factors to determine the quality of kochujang and preferred hot(621%) and bright red colored kochujang(70.6%) with fine red pepper powder Eighty seven percent of respondents preferred the traditional kochujang to the commercial one mainly due to the taste and the reliability to the materials kochujang. Especially all housewives at the age of sixty and over preferred traditional kochujang and those at twenties had a higher preferrence for the commercial one compared to other age groups. While 51.4% of the respondents consumed both e traditional and commercial kochujang, 16.2% and 32.5% did only commercial and traditional kochujang, respectively. Consumption of commercial kochujang decreased with age and main food with it was pan fried dishes(33.7%). Convenience(76.6%) was the major reason for purchasing commercial fried and most respondents(44.1%) selected the special brand from the previous experience of their own. Problems to be improved in commercial kochujang were better taste(31.3%) and development of diverse usage(62.4%).

  • The antiobesity effect of commercial kochujang and fermented wheat grains in Sprague-Dawley (SD) rats was studied. The experiment was consisted of 6 groups. Normal, high fat diet (HFD), HFD+raw wheat grains, HFD+first fermented wheat grains (FFWG, with Aspergillus oryzae) HFD+final fermented wheat grains (FiFWG, fermented more for 30~40 days), and HFD+ commercial kochujang. The results showed that final body weight, weight gain, food efficiency ratio, and adipose tissue weight were markedly decreased by the commercial kochujang and the fermented wheat grains, whereas non-fermented raw wheat grains had no such effect. Lipid contents such as total lipid, total triglyceride and total cholesterol decreased in the serum and organs of liver and adipose tissues by the commercial kochujang and the fermented wheat grains as well. These results also indicated that fermented wheat grains exhibited more suppressive effects on high fat induced-obesity than raw wheat grains. Increased fermentation time and adding the red pepper powder resulted in increased the anti-obesity effect. Especially, commercial kochujang showed higher antiobestic effects than fermented wheat grains. These in vivo findings suggested that well-fermented end products of the wheat grains and red pepper powder in kochujang could be useful in the prevention of obesity.

  • To study the characteristics and processing of Kochujang which is rapidly fermented by commercial enzymes, three kinds of Kochujang(KP-FA, KP-FN, and KP-BN) using commercial proteases and one Kochujang(KM) using Meju were prepared and their qualities investigated. There were only small differences in pH and acidity between each Kochujang. The moisture contents were high tendency in the three kinds of Kochujangs using the commercial proteases at 20 days of fermentation. Reducing sugars had a tendency to decrease during the fermentation in the Kochujangs using the proteases. During the first half of fermentation, the Kochujangs made with proteases showed higher amino nitrogen contents than the Kochujang(KM) made using Meju. Acidic protease activity was high in KP-FA at 20 days of fermentation and neutral protease activity was high in KP-FN and KP-BN at the beginning of fermentation. The Kochujangs made using the proteases, through 20 days of fermentation, obtained high preference in the sensory evaluation for color, texture, and overall acceptability. However, the hot taste was stronger in these Kochujangs during the fermentation.

  • General views of 1,436 housewives respondents through the country on commercial kochujang (fermented hot pepper-soybean paste) were surveyed by questionnaires. The 65.0% of total respondents had experience of purchasing commercial kochujang on the market, mostly super market (43.0%) of respondents, and the respondents who has job and live in apartment purchased the commercial products more often than the others (80.5%). The reason for purchasing commercial products were convenience (36.1%) and short of time (13.0%). The critera for purchasing commercial product were previous experience (40.1%) and well known trademark (20.6%) and not for purchasing were concerning of noxiousness (29.2%) and inferior taste (25.0%). Respondents prefered glass packing (44.3%) and plastic bottle (20.2%) of 500 g pack for single usage (42.3%). The most important standards for kochujang taste were pungency (59.1%) and savory taste (28.6%). The problems indicated to commercial products were inferior taste (32.2%), especially too sweet (52.6%), and safety (20.6%).

  • Time-dependent flow properties of commercial kochujang (hot pepper-soybean paste) were evaluated at various shear rates (5, 15, 25, and $35\;sec^{-1}$) and temperatures (5, 15, and $25^{\circ}C$). Flow properties of all samples showed thixotropic behaviors, which were qualitatively evaluated and quantitatively described by the Weltman, Hahn, and Figoni and Shoemaker models. Time-dependent flow properties of kochujang were found to vary over the range of the shear rate and temperature investigated. Time-dependent models of Weltman and Hahn were suitable ($R^2=0.923-0.987$) for commercial kochujang.

  • 일반 시판 개량메주 이외에 Aspergillus속 균주로 생산된 곰팡이성 개량메주 및 Bacillus속 균주로 생산된 세균성 개량메주로 각각 담금한 사과고추장의 숙성중 품질 특성에 대해 조사하였다. 총유리당 함량은 사과고추장(II)가 발효 10주에 22.43%로 가장 높았으며, 사과고추장(III)은 유리당의 구성에서 glucose비율이 현저히 높았다. 총 유리 아미노산 함량은 사과고추장(I)에서 107.53~401.52 mg%, 사과고추장(II)에서 108.69~441.19 mg% 사과고추장(III)에서 106.82~423.28 mg%였으며, aspartic acid와 glutamic acid가 높은 비율이었다. 견고성과 부착성은 사과고추장(I)에서 높은 경향을 나타내었으나 거침성은 3종의 사과고추장간에 차이가 거의 없었다. 사과고추장의 맛이나 색상에 대해서는 유의적인 차이가 없었으나, 향 및 전반적인 기호도는 사과고추장(III)에서 가장 높은 점수를 얻었다.

  • 본 연구에서 고추장 제조시 발효가 항돌연변이 효과와 in vitro 항암효과에 미치는 영향을 확인하기 위하여 고추장 제조 재료인 원료 밀, 1차발효밀, 2차발효밀, 최종발효밀, 고춧가루와 최종발효밀로 제조된 고추장의 Sal. Typhimurium TA100을 이용한 Ames test를 실시하여 MNNG에 대한 항돌연변이 효과를 살펴보았으며, HT-29 인체 대장암세포와 AGS 인체 위암세포의 성장 억제효과를 살펴보았다. 실험한 결과 원료 밀보다 1차발효밀, 2차발효밀보다 최종발효밀이 발효진행에 따라 점차 증진된 항돌연변이 효과와 in vitro 항암효과가 나타났으며 최종발효밀과 고춧가루로 제조된 고추장이 가장 높았다. 15, 30일 발효시킨 고추장이 발효되지 않은 고추장보다 더 높은 항암효과가 나타났다. 따라서 발효과정(기간)이 고추장의 항돌연변이 효과와 항암효과에 중요하게 관련되어 있다고 할 수 있으며 고추장의 주재료인 고춧가루의 capsaicin, 비타민C와 ${\beta}$-carotene 등의 작용만이 아닌 밀에서 온 발효 숙성 중에 많이 증식된 미생물 그리고 발효에 의한 생성된 다른 활성물질이 항돌연변이와 항암 효과에 관련되어 있다고 하겠다.
