The effects of cultivation methods (cultivation of curled-shaped type, M-1; conventional cultivation, M-2; growing after treatment with a growth regulator, M-3; cultivation by the combination of M-1 and treatment with oak charcoal, M-4) on the quality characteristics of soybean sprouts were studied by the measurement of growth characteristics. This study also investigated the changes in shelf-life stability of the new soybean sprouts (NSB) using M-4, which was cultivated with oak charcoal and treated with antimicrobial Citrus sunki seed extract. Among the soybean sprouts grown for six days at the high temperature and humidity environment (90$\pm$5% RH, 25$\pm$1$^{\circ}C$), M-1 revealed no significant difference in terms of quality, such as the harvest yield, the rot rate and the growth characteristics when compared with M-2. M-3 showed no significant difference in growth characteristics, of hardness, and sensory evaluation scores when compared with the soybean sprouts grown by conventional methods. NSB had a low number of total microorganisms and had a better appearance after five days of storage than did the control group (M-2). These findings demonstrate that chemical-free and clean soybean sprouts can be grown by combining oak charcoal and antimicrobial Citrus sunki seed extract, thereby meeting the consumer demand for safe, chemical free sprouts.

감귤 6종류의 종자를 메탄올로 추출하여 이들 추출물에 의한 N-nitrosodimethylamine(NDMA) 생성억제효과를 검정하였다. 감귤류 종자의 수분함량은 4∼6%, 조단백질 함량 11∼15%, 조지방 32∼46%, 탄수화물 함량은 22∼45%이었으며, 회분함량은 2∼4%, 플라보노이드는 12∼24mg%, 폴리페놀함량은 22∼53mg%이었다. 감귤종자 메탄올 추출물의 추출수율은 0.7∼1.1%, 고형분 함량은 0.8∼1.2%이었다. 감귤종자 메탄올추출물에 의한 아질산염의 소거효과는 추출물의 첨가량이 증가할수록 그 소거율이 증가였다. 또한 아질산염 소거능은 pH 의존성이 커서, pH 1.2(42.7∼96.9%)에서 높은 가장 높은 소거효과를 보였으며 pH 6.0(19.9∼62.6%)에서 가장 낮은 효과를 보였다. 게다가 반응시간에 따른 아질산염 소거효과는 3시간 반응시켰을 때 가장 높았다. NDMA 생성 억제효과는 감귤 종자 추출물의 농도가 증가할수록 컸다. 즉 감귤종자 추출물을 각각 1, 3 및 5$m\ell$ 첨가하였을 때 NDMA 생성 억제율은 각각 1.2∼39.8%, 21.3∼60.1% 및 47.4∼94.0%이었다.
