Abstract

Effects of azodicarbonamide (ADA) were investigated on the rheological properties of flour dough by measuring farinogram, amylogram and extensogram based on the amount of ADA added. Quality characteristics of the bread made with the ADA added dough were also evaluated by measuring dough volume, moisture content, pH, proofed time, baking loss and textural characteristics. The farinogram showed that water absorption, stability and elasticity of the dough with ADA were higher than those without ADA. However, its absorption time and weakness decreased compared to the dough without ADA. Through the amylogram, it was found that gelatinization temperature and maximum viscosity increased, but temperature of maximum viscosity reduced in the dough with ADA. The extensogram showed that the area and resistance of the dough increased slightly but extensibility decreased drastically after fermentation, resulting in the ratio of resistance and extensibility (R/E) of the dough with ADA was lower than those without ADA. The bread prepared with the dough containing ADA after freezing up to 12 weeks showed higher pH and specific loaf volume but lower moisture content, second proof time and resistance than those without ADA.

냉동 반죽 제조시 azodicarbonamide(ADA) 첨가량을 달리하여 만든 냉동 반죽의 물성에 미치는 영향인 farinogram, amylogram, extensogram을 비교 조사하였고, 냉동 반죽의 품질을 결정하는 2차 발효 시간, 빵 제품의 pH, 수분 함량, 비용적 및 경도에 미치는 영향을 -20$^{\circ}C$ 냉동고에서 제조 직후부터 12주까지 저장하면서 비교 조사하였다. ADA 첨가량이 증가할수록 farinogram에서 반죽의 흡수율, 안정도와 강력도는 증가하고, 흡수 시간과 약화도는 감소하였으며, amylogram에서 호화 개시 온도와 최고 점도는 증가하고, 최고 점도시 온도는 감소하였다. 또한 extensogram에서는 발효시간 45분에서 면적, 신장도와 저항비는 증가하고, 저항도는 감소되었다. 냉동 반죽 제빵법으로 만든 냉동 반죽은 같은 냉동 저장 기간에서 ADA 첨가량이 증가할수록 2차 발효시간, 수분 함량 및 경도 값은 감소하였으며, pH, 비용적은 증가하였다.
