        본 연구는 고기능 미래 식량자원으로서 이용 가치가 높은 밀웜과 검은콩을 첨가한 쿠키를 제조하고, 밀웜 및 검은콩 첨가량에 따른 품질특성, 항산화 활성, 기호성을 비교해 보고자 수행되었다. 밀웜의 첨가량을 0%, 10%, 20%, 30%로 증가한 쿠키와 밀웜과 함께 검은콩 분말 10%, 20% 를 첨가한 쿠키를 제조하여, 품질특성, 항산화 활성, 관능 특성을 비교한 결과는 다음과 같다. 팽창율, 손실율은 밀웜만 첨가한 쿠키와 밀웜과 검은콩 분말을 함께 첨가한 쿠키 모두에서 밀웜 분말 첨가량이 증가함에 따라 유의적으로 증가하였다. 총 폴리페놀 함량, DPPH 라디칼 소거능, FRAP, ABTS 측정 결과 밀웜 분말과 검은콩 분말을 첨가한 쿠키 모두에서 아무것도 첨가하지 않은 쿠키보다 활성이 높게 측정되었다. 밀웜 분말의 첨가량이 증가할수록 항산화 활성은 증가하여 밀웜 분말 30% 첨가군에서 가장 높은 항산화 활성을 나타내었다. 또한 동일한 양의 밀웜에 검은콩 분말을 함께 첨가한 쿠키는 밀웜 분말만 첨가한 쿠키 보다 총페놀함량, DPPH 라디칼 소거능, ABTS 라디칼 소거능이 높게 측정되었다. 밀웜만 첨가한 쿠키의 색도는 첨가량이 증가할수록 쿠키의 밝기(L 값)와 황색도(b 값)는 유의적으로 감소하고, 적색도는(a 값) 증가 하였고, 밀웜과 검은콩을 함께 첨가한 쿠키는 적색도(a 값), 밝기 (L 값), 황색도 (b 값)가 모두 감소하는 것으로 측정 되었다. 쿠키의 조직감 측정결과 밀웜 첨가량이 증가할수록 쿠키의 강도가 유의적으로 감소하였으나(p < 0.05), 검은콩을 함께 첨가한 쿠키는 강도가 강하게 나타나 밀웜 증가에 의한 쿠키 강도의 감소를 검은콩을 첨가함으로써 개선할 수 있었다. 이상의 결과에서 밀웜 쿠키의 품질특성, 항산화 활성, 기호성을 모두 향상하기 위해서는 밀웜 분말을 10% 첨가하여 제조하는 것이 가장 우수하다는 것 을 알 수 있었다.

        This study was done in order to investigate the changes in quality of Cheonggukjang for soybean cultivars during fermentation. Cheonggukjang of 14 cultivars that were inoculated with Bacillus subtilis 15893 was produced, and, then, it was measured for hardness, proximate composition, amino nitrogen, enzyme activity, and total aerobic bacteria counts. In a raw bean, the highest hardness value was 16,975 g from Sunyu. In a steaming bean, Jangwon had the highest hardness value and the lowest aerobic bacteria counts of forty-eight hours fermented Cheonggukjang. Saedanbaek, whose protein contents was highest in raw bean, was also highest in Cheonggukjang. The amino nitrogen content of twenty-four hours fermented Cheonggukjang was highest in Saeol and Sunyu while forty-eight hours fermented Cheonggukjang was highest in Singi, Daol, and Milyang 231. In the protease activity, Saedanbaek had the highest and total aerobic bacteria count that were either increased or held as time went on ; twenty-four hours fermented Cheonggukjang was highest in Milyang 231 and Keunol while forty-eight hours fermented Cheonggukjang was highest in Chunsang.

        This study was performed to increase the yield and to reduce the processing times for the preparation to improve the productivity and quality of rice jochung, a traditional food in Korea. In order to evaluate the quality characteristics and yield of jochung, the viscosity, color value, mineral contents and the sensory evaluation were measured. Jochung is prepared from steamed rice (STR), wet-milled rice flour (WRF) and dry-milled rice flour (DRF) by processing methods of rice and reacting times (6 hours or 13 hours) of liquefaction and saccharification. There is commonly added liquefying enzyme for rice liquefaction (0.4%/10 kg rice, at 85~90℃ for 1 hour or 4 hours) and saccharogenic enzyme with malt (2.5% or 4.5%/10 kg rice, at 56~60℃ for 5 hours or 9 hours). The inner structural properties of WRF showed the more distinct shape regular structure of uncombined starch particles but the DRF closely maintained particles of rice flour observed by SEM. If processing times for liquefation and saccharification were reduced from 13 hours to 6 hours, the yield of jochungs prepared with WRF increased 8%, the DRF 7%, and the STR 3% respectively and the sensory evaluation as well as color values and overall desirability received high scores. The viscosity, color a and b values of jochung processed with WRF for 6 hours were lower than that processed for 13 hours. The viscosity and color a, b value and Ca content were decreased in the jochung processed with WRF or DRF for 6 hours, but Mg, P and K were increased than that of STR. Jochung processed by 0.4% liquefying enzyme and 2.5% malt with WRF for 6 hours will increase the yield, save manufacturing times and costs and will thereby enable cost-effective techniques.
