Study on the preparation of the saccharification kochujang with retrogradated starch food and changes in physiochemical properties during the aging

노화된 전분식품을 이용한 당화고추장의 제조 및 숙성 중 성분 분석 연구

This study was attempted to investigate changes in physiochemical properties of the preparation of saccharification kochujang with retrogradated cooked rice, bread, rice cake and sensory evaluation during 60days aging. 1. Moisture content in 4 samples were slowly increased and pH of kochujang was slowly decreased during aging. 2. Reducing sugar content were about 1.4~2 times higer than $T_3$ and $T_2$ at 50days of aging. 3. In no significant difference 4 samples, the level of adipic acid, citric acid, malic acid was the most and that of acetic acid, iso-butyric acid, fumaric acid, lactic acid, tartaric acid was smaller. 4. Sensory evaluation conducted by fifteen university students as panelist showed that their were more significant difference among four samples and notable preferance for $T_3$ over $T_0$, $T_1$, $T_2$.
