본 연구에서는 인산염과 가스첨가제를 첨가한 된장 시료군과 첨가하지 않은 된장 시료군 간의 이화학적 분석 결과 및 관능적인 품질 특성에 대하여 연구하였다. 제조된 된장을 28일간 저장하면서 이화학적 분석 및 색상 변화 측정, 관능평가 등 분석을 실시하였는데, 인산염과 가스첨가제를 첨가한 된장 시료 C의 경우가 된장에 인산염만 첨가했을 때의 된장 시료 B, 인산염과 가스첨가제를 첨가하지 않은 된장시료 A와 비교하여 색상에 있어서 좋은 품질을 유지하였

Browning of commercial Doenjang product during storage and marketing is a main concern in the industry. There have been many studies on the improvement on the quality of Doenjang during storage. In this study, phosphate and gas absorber treatment was introduced in manufacturing of Doenjang to improve the color of commercial Doenjang during storage. Doenjang treated with Phosphate and 9as absorber (sample C). Doenjang teated with Phosphate only (sample B), and the control (sample A) were prepared and their physicochemical and sensory properties were determined during storage at for 28 days. Sample C was the best in terms of color as well as sensory evaluation resulting in preventing browning of Doenjang during storage. These result suggest that commercial production of Doenjang should introduce phosphate and gas absorber treatment to improve the quality of Doenjang, and to prevent undesirable browning reaction during storage and marketing.
