Abstract
To evaluate the effects of sucrose-fatty acid ester (SE) on bread-making characteristics, the dough mixing, gelatinization, baking properties with the addition of SE alone and together with other surfactants were investigated. SE increased the peak time and the peak height in mixogram, indicating that it contributed the elasticity of dough. In farinogram, SE increased the peak time and mechanical tolerance index, but reduced the dough stability. SE increased the peak viscosity and reduced the gelatinization temperature and maximum consistency temperature in amylogram. SE increased the specific volume of bread loaf and retarded the increase in hardness of bread during storage, showing its anti-staling effects. The maximum anti-staling effect of SE was observed at 0.5% level. The addition of SE (0.2%), SSL (0.15%) and ES-95 (0.15%) blend showed the maximum specific loaf volume, and that of SE (0.25%) and SSL (0.25%) did the maximum anti-staling effect.
자당-지방산 에스테르(Sucrose-fatty acid ester, SE)가 제빵특성에 미치는 영향을 분석하기 위하여 반죽특성, 호화특성, 제빵특성 및 노화방지 효과를 조사하였고, 다른 유화제와 혼합, 비교실험을 하였다. SE의 첨가에 의해 peak time과 peak height를 증가 시켜 반죽 탄성이 향상되었고. farinogram 특성은 SE 0.5, 1.0% 첨가에 의해 peak time과 mechanical tolerance index (MTI)는 증가하였고 stability는 감소하였다. 호화개시온도, 최고점도시 온도는 감소하였으며 peak viscosity는 증가하였다. 제방특성은 SE의 유화제로서의 작용에 의하여 빵의 비체적을 증가 시켰으며, 빵의
