본 연구는 청국장을 만들기 위해 사용되는 콩 중에서 발효가 되지 않아 버려지는 콩을 이용하여 친환경농업에 맞는 유기질비료와 액비로서의 활용 가능여부를 알아보기 위해 충남대학교 부속농장 유리온실에서 1/5000a Wagner pot을 이용해 상추 재배시험을 수행하였다. 생육조사 결과 엽장의 경우 대조구와 청국장 콩을 첨가한 CS 처리구는 비슷한 결과를 보였으며, 청국장 콩 추출액(액비)을 엽면시비 한 CSE 처리구의 경우 26~33% 증가율을 보였다. 그리고 엽폭과 엽수에서도 CSE 처리구가 대조구보다 9~20%정도 높은 결과를 나타냈다. 생체중은 청국장 콩과 추출액(액비)을 엽면 시비 한 CSE 처리구가 대조구에 비해 9~27% 정도 수량증가 효과를 보였고, 퇴비와 청국장 콩 추출액(액비)를 추비형식으로 시비한 CE 처리구에서도 대조구보다 최대 26% 정도 수량증대 효과를 나타냈다. 따라서 청국장 제조시 버려지는 미 발효된 청국장 콩과 추출액(액비)이 친환경농업에 맞는 유기질비료와 액비로서의 가치가 있는 것으로 판단된다.

Jeung-pyun, a very popular fermented rice cake consumed in Korea, consists mainly of rice, rice wine (Tak-Ju), and sugar. The effects of addition of different beans on the quality characteristics of the batter and Jeung-pyun were investigated. Six different beans were mixed with the rice flour at levels of 5% and 10% of the rice flour weight, respectively. The addition of Back-tae, Huk-tae, Sori-tae, which are types of soybeans, and black gram significantly increased the batter volume and viscosity. However, the fermented Back-tae (Cheongguk-jang) was not effective at increasing the batter volume and viscosity. The buffering effect of the beans was very significant on the fermented batter, and the decrease in pH of the fermented batter made with beans was less than that of the control batter without beans. Additions of the soybeans and Cheongguk-jang were most effective for the buffering effect in the fermented batter. Although the Back-tae, Huk tae, and Sori-tae were different colors and shapes, they were all soybeans and exhibited similar effects on the Jeung-pyun batter. However, the effects of the beans were not significant on the Jeung-pyun. The volume and moisture content of the Jeung-pyun made with beans were not significantly different from the volume and moisture of the Jeung-pyun made without beans. The above results suggest that the addition of different soybeans, mung beans, and black gram significantly effects on the properties of Jeung-pyun batter, but not Jeung-pyun itself.
