Abstract

The purpose of this study was to compare the quality characteristics of each brown rice glutinous rice red pepper paste prepared. In this study, brown rice, glutinous rice, and red pepper paste were prepared with various enzyme preparations. A 20-day study of the physicochemical and microbiological properties of each enzyme through the results process showed significant differences. In particular, brown rice red pepper paste manufactured using cozies purchased from Sunchang was functionally superior to rice cozies and bean cozies, with probiotics of 7.1-7.5×107 CFU/mL, lactobacillus of 1.9-2.2×103 CFU/mL, 48.67-52.30%, and 58.57-63.90%. When the results were combined, the composition of microorganisms and enzymes of fermented soybean paste purchased from Sunchang was not confirmed, but brown rice chili paste with nutritional and functional properties could be prepared compared to A.oryzae and A. kawachii.

본 연구에서는 순창에서 구입한 메주와 Aspergillus kawachii를 접종한 쌀코지, Aspergillus oryzae를 접종한 콩코지를 이용하여 제조한 현미찹쌀고추장의 품질특성을 비교하고자 진행하였다. 효소제를 달리하여 제조한 고추장을 제조한 뒤 총 20일간의 발효 기간을 거쳤다. 발효 기간이 경과함에 따른 효소제별 이화학적 및 미생물학적 특성을 연구를 하였다. 이화학적 특성(산도 및 pH, 당도, 수분함량, 색도, DPPH 및 ABTS radical 소거활성 측정)과 미생물학적 특성(생균수 및 유산균 수 측정)을 분석한 결과 첨가량에 따른 유의적인 차이는 나타나지 않았으나, 효소제에 따른 유의적인 차이는 있는 것으로 나왔다. 특히 순창에서 구입한 코지를 이용하여 제조한 현미찹쌀고추장은 7.1-7.5×107 CFU/mL의 생균수, 1.9-2.2×103 CFU/mL의 유산균수와 48.67-52.30%, 58.57-63.90%의 DPPH 및 ABTS 라디칼소거능이 있어 쌀코지와 콩코지에 비해 기능적으로 우수함이 있는 것을 확인하였다. 결과를 종합하였을 때, 순창에서 구입한 메주의 미생물 및 효소제의 조성은 확인하지 않았으나, A. oryzae, A. kawachii에 비해 영양적, 기능적 특성이 확보된 현미찹쌀고추장이 제조되어질 수 있음을 확인하였다.
