Abstract

Changes in quality characteristics of gochujang prepared with different ingredients (white rice, barley, sorghum and millet, bamboo salt) and meju starters were studied. The gochujang samples were fermented for 6 weeks at $40^{\circ}C$ and analyzed for changes in their physicochemical properties and sensory characteristics. Eight different gochujang samples were prepared: WR-SS-AB, WR-SS-ABL, WR-BS-AB, WR-BS-ABL, MG-SS-AB, MG-SS-ABL, MG-BS-AB, MG-BS-ABL (WR: white rice, MG: mixed grains, SS: solar salt, BS: bamboo salt, AB: Aspergillus oryzae/Bacillus subtilis starter meju, ABL: Aspergillus oryzae/Bacillus subtilis/Lactobacillus plantarum starter meju). There were significant differences between experimental groups in terms of moisture content, pH, acidity, and color value. All gochujang samples showed increased moisture contents and pH as well as increased acidity and amino-type nitrogen during fermentation. MG-BS-ABL showed the highest contents of amino-type nitrogen and free amino acids after 6 weeks of fermentation compared with other experiment groups. In addition, MG-BS-ABL showed the highest sensory analysis score, including appearance, flavor, taste, and overall acceptability after the fermentation of samples. Based on the results, MG-BS-ABL exhibited similar quality characteristics as general gochujang but showed the highest sensory scores and contents of amino-type nitrogen and free amino acids. These results might be due to the high protein contents of mixed grains and high mineral contents of bamboo salt and fermented products from mixed probiotic starters.

고추장 재료(잡곡, 죽염)와 종균을 이용하여 제조된 고추장은 일반적인 고추장에 비해 수분 함량, pH, 산도, 색도는 특별한 차이를 보이지 않았다. 모든 고추장 시료는 발효기간이 지남에 따라 수분 함량은 증가하고 pH는 감소하였으며, 산도, 아미노태 질소는 증가하였다. 잡곡과 죽염, 유산균이 들어간 혼합균주 스타터 고추장(MG-BS-ABL)은 6주간 발효되었을 때 아미노태 질소, 유리아미노산의 양이 다른 고추장에 비해 유의적으로 많은 것으로 나타났다(P<0.05). 또한, 관능평가에서 외관, 향기, 맛, 전반적인 기호도가 모두 다른 고추장에 비해 높은 점수를 나타내었다. 이상의 결과로 MG-BS-ABL군은 일반적인 고추장과 유사한 고추장의 품질 특성을 나타내었으며, 아미노태 질소, 유리아미노산의 함량이 높아 관능평가에서도 높은 점수를 얻은 것으로 생각된다. 이 결과는 아마도 기장에 함유된 높은 단백질의 함유량과 죽염의 미네랄 조성, Aspergillus oryzae, Bacillus subtilis와 Lactobacillus plantarum의 혼합균주 메주의 발효에 의한 것으로 생각한다.
